Where can I get installation manuals and specification sheets? Our product documentation is hosted. Visit http://www.ValcomES.com/install

How do I purchase your products? It depends on the application. Contact [email protected]

Are there any special prerequisites for purchasing? If you are purchasing certain IP products, there is a prequalification process.

Can I register a project that I’ve cultivated? Yes, we offer project registration for qualified projects. If a company registers a project with us, there are 3 benefits. 1) We will not allow another company to register the same project. 2) We will offer our best pricing. 3) If you pursue the project in a reasonable amount of time, we will not provide a quote for the registered project to any other company.

What are the advantages of IP speaker systems? Valcom IP speakers systems have many benefits. We have a partial list of those benefits here.

What are the network requirements for IP speaker systems? We maintain a document that outlines network requirements and a proper initial setup procedure. It may be found here.

What are the advantages of Valcom Self-Amplified systems? When Valcom Self-Amplified Speaker technology was introduced in 1977, it became a “Why didn’t somebody think of this before?” moment. It has since become the technology Engineered, Built and Supported in the U.S.A.

of choice for tens of thousands of integrators large and small. A partial list of the advantages of Valcom Self Amplified Speaker technology is available here.

If I just need to replace a 70.7 or 25-volt amplifier, but the client and I prefer a product that’s manufactured in the U.S.A., what should I use? Valcom manufactures central amplifiers under the Clarity and PagePac brands.

How can I get expert assistance in responding to an RFP? We will be pleased to review any published RFQs or RFPs associated with your opportunities, however, it’s rare that these documents provide the device types and counts required to provide a quote. RFPs and RFQs are often crafted from bid specifications provided by manufacturers and written around specific products. Manufacturers write their bid specifications in such a way that only their products may be considered. These documents often require rarely, or never used features and functions that are specific to one manufacturer. Occasionally, RFPs and RFQs represent products on which an end user has standardized. These often disallow substitution and may, if reissued without the benefit of oversight, perpetuate the use of old technologies. Too often, however, RFPs and RFQs are fabricated using cut and paste from various manufacturers’ bid specifications and cannot be met line-by-line by anyone. Many times, strict adherence to RFPs and RFQs can limit an End User’s options in obtaining superior state-of-the-art solutions offering all of the features that they really need. In most cases, what’s truly important is meeting or exceeding the intent of the specification. We still see newly published RFPs and RFQs that were written in the 1950s. If no one had ever worked to modernize these, we’d all be using rotary telephones, switch bank manual intercoms and old fashioned central amplifiers. Remember that RFPs simply indicate a need and are a starting point towards obtaining the best solution to satisfy that need. Providing this solution is the best service that we can provide to the End User. Superior results are realized when you work proactively with specifying authorities and End Users to educate them on the best solutions available. If your company simply responds to published RFPs and RFQs, and those RFPs specify dated technology, then we will offer a better solution using our innovative products. It is our task, together, to work with specifying authorities to teach them why Valcom solutions are better. We have a great deal of marketing collateral to support this fact and we will gladly participate in webinars, conference calls, and, when practical, live demonstrations to decision makers. We offer great solutions; therefore, we have had great success with this strategy. Engineered, Built and Supported in the U.S.A.

As a manufacturer, our quotes are based upon customer provided material lists. If you provide the information required to do so, we can assist in product selection. The solution that we suggest can only be as accurate as the information that you provide. Our public address system design guide will help you to provide the information that we need to provide a complete and accurate suggested equipment list for your application.

What does Valcom ES need in order to provide design suggestions? We always want to provide the right products for your application. The accuracy of our suggested equipment is directly related to the level of detail provided to us. We have a site survey and public address system design guide to help you gather the right information for a great design!

How do I design a public address paging system? It’s actually quite simple. Probably the most difficult part is choosing from our many speaker and clock styles. Our site survey will help you to gather site information and our public address system design guide will help you to determine speaker quantities and desired features. Once that’s done, or anytime during the process, give us a call and we’ll help you pick the right control equipment.

Does Valcom offer wireless PA systems? Wireless PA systems are never truly “wireless”. Wireless PA systems simply have no wired audio connection to a shared audio distribution frame. By using a properly configured 802.11 wireless network for your audio distribution, most Valcom equipment can be deployed “wirelessly”.

How do I design a K-12 school intercom system? A school intercom system design is just like any other. The only difference is that K-12 schools use a lot of features. For that reason, we’ve developed a K-12 system questionnaire and design guide. As concern for crisis preparedness grows, K-12 facilities often require both an emergency notification system and a bell/clock/intercom system. A cost-effective approach is selecting an emergency notification system that also offers all of the functions of a bell/clock/intercom system. Benefits of this approach include: 1) Labor savings. Stand-alone emergency notification systems, even supervised systems, must be tested periodically to verify operation. By utilizing the system daily for intercom and general announcements, operational testing requires little or no additional effort.

2) Significant cost savings results from using speakers, visual messaging LED signs and core equipment for both emergency notification and daily intercom/paging. 3) One system results in less maintenance. 4) One system results in less training. 5) Daily use means that periodic refresher training is unnecessary.

Where is Valcom equipment manufactured? We are proud to be a U.S. manufacturer with a Virginia based facility. We do our own electronic, software and mechanical engineering. We have a full-service metal fabrication shop to build our high-quality enclosures; we make our own transformers and build each circuit board using both automated and manual processes.

What are some common features for specific vertical markets? Our design guide lists common features for vertical markets.

What are some best practices for public address system installations? We’re glad you asked. Best practices come from many years of experience and can help you to avoid costly mistakes and facilitate future additions and maintenance. We offer a regularly maintained published Best Practices and General Troubleshooting Guide.

What are some general troubleshooting techniques? What tools will I need? We offer a regularly maintained published Best Practices and General Troubleshooting Guide.

Why do I need an Emergency Mass Notification system if I already have a public address system? A properly configured public address system is actually the best kind of emergency mass notification system. It can instantly communicate with everyone on a site. The problem is, public address systems don’t communicate with people who might be coming to the site, and they may or may not communicate with hearing impaired individuals. An emergency mass notification system should always use a properly configured public address system as its core, however there’s more to consider. It should have: 1) Visual signage for hearing impaired individuals, or just for those listening to headphones. 2) Remote notification capabilities like e-mail, Facebook. Twitter, etc. 3) Supervision, so you know it’s ready when you need it. Valcom Engineered Solutions is a leader in emergency mass notification. Our offerings are best discussed in conversation. Give us a call! We’re always glad to help.

Where do I find the latest programming software? All the latest Windows based programming tools are found here.

Can a Valcom solution integrate with my existing communication systems? The answer is almost always yes. We can integrate with all kinds of telephone systems, analog, IP, hosted. We can reutilize existing speakers, cabling, amplifiers, notification systems, etc. Let us know your vision and let’s find a way to make it work! We’ve been doing this for a long time.

Can you explain the difference in the various IP gateways and servers? In addition to many styles of IP speakers and horns, Valcom Engineered Solutions offers many gateways to transition to and from analog audio, inputs, telephone systems, microphones, music sources, etc. We also offer application servers that provide higher levels of system functionality and advanced features. We publish a document discussing each. That document is available here.

Can you outline your VoIP Intercom capabilities as they relate to integration with Cisco Call Managers? Regarding our VoIP intercom devices, they register to CUCM as a third-party SIP Device (Basic) and (from the CUCM perspective) look like a single-line phone. The user can call it directly by its Directory Number, and it can be programmed to automatically ring down to a predetermined number when the Call Button is pressed. The ring down can be to a single extension or to a hunt group. The intercom includes a relay mounted on the doorplate speaker to unlock doors. If the speaker is in an unsecured location, there is also a separate relay module included to allow putting the door unlock relay inside the building in a protected area. Email [email protected] for more information.

What are the options for correcting clocks? Valcom offers analog and digital display clocks. These clocks can be corrected by a variety of methods including NTP, digital correction and wireless. We also honor many of the old synchronous wire correction schemes. Info may be found in our Best Practices and General Troubleshooting Guide or on our website.

I need brochures and catalogs for my local Architects and Engineers. Where can I find current content? Send them this link http://www.ValcomES.com/esd.

What about warranty? Valcom offers a one-year warranty free of charge. The details may be found here. Manufacturers often offer warranties beyond one year and hide the cost in the selling price. Valcom offers warranties beyond one year at a transparent optional charge. The cost varies by system.

Our facility director would like to install a 2-way intercom/paging system, but we can only afford a one-way system. Can we upgrade later? It’s a common misconception that 2-way talkback systems cost more than one-way systems. They can actually cost less in many cases. Give us a call to discuss your specific application.

What is SIP and how does it work with Valcom IP endpoints and gateways? SIP is Session Initiation Protocol. In telephony, there has always been a clear distinction between two different phases of a voice call. The first phase sets up the call. with all of the details needed to get two telephones communicating. Once the call has been setup, the phones enter a mode using data or voice and an entirely different set of protocols to transfer voice between the two phones. In the world of VoIP, SIP is an application layer call setup protocol. A simplified example of SIP communication with Valcom IP endpoints and gateways designated as SIP stations may be found here. Endpoints and gateways may also be defined as SIP trunks if necessary. Additional info may be found in our Best Practices and General Troubleshooting Guide

What are the advantages and disadvantages of using SIP access for paging/intercom systems? SIP is Session Initiation Protocol. Announcing or broadcasting messages across your entire office or complex has never been easier with VoIP/SIP paging. Any organization from schools, offices, car dealerships, or manufacturers that need to quickly and effectively alert an entire team or, just a small group, can benefit from the advanced features and functions now available from VoIP/SIP paging systems. With a network based VoIP/SIP paging system you'll enjoy a quicker and more flexible installation than traditional wired, analog systems and you'll eliminate the need for separate voice and data networks. Most Valcom IP endpoints inherently support both the SIP and Valcom VoIP protocols. It’s even possible to use both in the same system. When SIP access is used exclusively, SIP licenses may be required for each endpoint, Valcom VoIP protocol, on the other hand, does not require licensing. SIP access typically results in shorter dial strings to access speaker zones, however SIP access is completely dependent upon the IP telephone system and, should it fail, both speaker and phone internal communications are lost. When choosing SIP access, it’s a good practice to include one or more dedicated paging

telephones, independent of the IP phone system, to allow speaker communication to continue in case the IP phone system should fail.

What is the difference between a PA system, a Public Address System, an Intercom System and an Emergency Mass Notification System? A PA or Public Address System is typically a local one-way speaker system intended to deliver audio announcements to a facility. An Intercom System is typically a bidirectional speaker system with the ability to initiate conversations from any speaker location. Public address and intercom systems are often one and the same and offer both one-way and two way capabilities. Emergency Mass Notification Systems (EMN Systems) are communication systems designed for managing crisis situations. EMN systems often feature all of the capabilities of a public address/intercom system along with capabilities to provide secondary alerting through signage, two way radios, social media, email, cell phones, etc. EMN systems often provide coverage spanning large geographical areas. When planning new or upgraded internal communications, it’s advantageous to consider EMN needs up front. This strategy saves money long term by putting systems in place that can easily and cost effectively grow along with your organization.

Do VoIP clock/speaker combination products require one, or two PoE Ethernet connections? Both the clock and the speaker are powered by and communicate through a single PoE switch port. Network requirements may be found here.

Are there guidelines for commissioning a PA/Intercom system? Every system has its own unique features. Therefore, the commissioning process will vary. We have published some general guidelines here: PA/Intercom Site Commissioning Guidelines.

How can I send automatic messages across my public address system? There are many ways to accomplish this. If you already have a system or source that produces the audio, we can easily distribute that audio facility or area wide. If you don’t already have the audio source, we offer several options to serve WAV files, prerecorded audio or text-to-speech audio. The messages can be triggered numerous ways. We can accept many data feeds like syslog, RSS, Atom and CAP feeds or physical inputs like pushbuttons, relay closures or phone dial codes. We also support message launch from browsers or PC desktop shortcuts. Give us a call to discuss the right solution for your application.

How can Valcom Engineered Solutions support me in winning a job? Just tell us what you need! Webinar? Site visit? We’ll support you in any reasonable fashion. We don’t just want to win one job with you; we succeed by helping your business succeed. There’s an old saying, “If you want to go fast, go alone, if you want to go far, go together.” Let’s go far, together!

If I can make announcements through my telephone speakers, why would I need a public address system? Imagine yourself sitting at a desk, in a quiet area, talking on a speakerphone. There’s no problem with that. Now imagine yourself talking on a speakerphone from the back of a room of noisy people. Not quite the same. Speakers in telephones are only designed to provide audio to a small, quiet area like a conference table or private desk, not an entire room. However, paging through telephone speakers as well as overhead speakers is a great solution. We do this on a regular basis. Ask us how!

How can I interface an analog intercom with a hosted phone system? With a number of institutions migrating to hosted solutions for their phones, there is often a need to interface an existing Class Connection ES or Multipath system with the new hosted solution and still retain functionality of the classroom call buttons. One suggestion would be using a locally accessible FXO port on the hosted phone system to interface with the admin ports of the analog intercom. Another solution would be to provide dedicated analog telephones to interface with the analog intercom. Alternately, a Valcom FXO Gateway may be added to provide 2-way SIP access to the analog intercom. In any case, it’s suggested to utilize at least one dedicated POTS phone to ensure that intercom access is available should the hosted phone solution be inaccessible.

How can I interface a Valcom system with an on-premise phone system? It depends on the system. Single zone one-way systems might possibly connect to the telephone system’s page port. Multizone systems will require some means of selecting the desired zone. This may be accomplished via DTMF using Loop Start Trunk Port, Loop Start C.O. Line Port, FXO port, Analog Station Port or via Session Initiation Protocol (SIP). Analog Station Port access requires that the port provide some non-standard* indication that the caller has completed the announcement and is therefore the least desirable option.

SIP access may require annual license renewals with the telephone system manufacturer and may also require one or more Valcom SIP Paging Gateways to perform group announcements. Loop Start Trunk Port, Loop Start C.O. Line Port or FXO port access is often the preferred method and simply requires that the selected Valcom equipment provide one or more analog dial tone I/Os. *Station level access requires calling party disconnect (aka open loop disconnect), complete silence on the idle station or may use a set time out.

Should I use telephones or microphones to access my Public Address System? Telephone based access is almost always preferred due its ability to dial access multiple zones, engage in 2-way talkback intercom conversations and the ability to make announcements from any designated telephone system station (phone). Limited use microphones may also be included in a system designed for telephone access.

What kind of wire do I need for non-IP wired clocks? We suggest using UTP cabling for our wired clocks. Here are some guidelines. Using 24 AWG UTP for 24V Clocks

What is your IP6000 System? IP6000 is the IP based product line of Valcom Engineered Solutions. Valcom IP Mass Notification/Intercom systems are used in many applications from school intercoms to full scale multimodal emergency mass notification. They differ from analog wired systems in numerous ways. Using the IP network to support facility systems, including mass notification and intercom has caused the role of Network Administrator to gain increased prominence in every professional and government organization. One reason for this is the fact that hosting facility systems on a LAN/WAN provides many benefits, not the least of which - long term cost savings. Managing multiple IP based systems typically requires fewer personnel since most adjustments and diagnostics may be performed remotely. That means less time lost driving to sites, fewer service vehicles required, less vehicle insurance cost, less fuel cost, and more multitasking. Unlike analog systems, Valcom IP Mass Notification/Intercom systems do not require a central control system. They are hosted on the LAN/WAN, therefore the physical location of endpoints and their proximity to each other is irrelevant. Also, unlike analog systems, system size constraints are essentially non-existent. These systems are easily deployed on a facility, enterprise and/or global scale. Valcom’s server-less design means that as long as properly configured network connectivity exists between endpoints, they will be able to communicate. This robust, redundant strategy coupled with inherent supervision, explains why Valcom IP Mass Notification/Intercom systems are utilized in some of the most vital facilities in the world. A full complement of one-way or intercom POE speaker and horn endpoints are available to suit any area. These speakers and horns may be selected in any combination conceivable for announcements to a single area, multiple areas, or everywhere. Access may be via single line POTS type telephones, FXO ports, loop start C.O. line ports, loop start trunk ports, SIP, microphone or analog station ports (FXS) featuring Open Loop Disconnect. Visual notification endpoints, such as LED displays, may easily be incorporated into your design to deliver messages to high noise areas, to benefit hearing impaired individuals, or anywhere that visual alerting is desired. Input/output gateways allow users to launch messages from panic buttons or automatically from 3rd party monitoring devices. They also provide switch outputs to control electric door locks, lighting or any other facility system.

Audio gateways allow the introduction of music, microphone or other external audio sources. They may also provide audio outputs to facilitate integration of existing legacy analog paging systems, radio systems, etc. Although the Valcom IP Mass Notification/Intercom systems feature a server-less design, there are Application servers available to provide desirable features. Telephone Paging Servers allow the broadcast of system announcements through the speakers of many existing IP telephones. This simple addition adds audio coverage to private offices and other areas that may not be close to a system speaker. Application Servers may be added to provide scheduled tones, music, prerecorded or live announcements. They also provide a graphical browser interface to launch messages or monitor call status. Application servers feature the ability to monitor data feeds such as syslog, RSS, ATOM or CAP feeds to automatically launch one or more messages to speakers/horns, IP telephone speakers, text to LED signs, as well as screen pop ups on PCs. All of the messaging modes may be simultaneously initiated from a single user action. Advanced Servers allow users to launch their own emergency announcements via CAP, RSS and/or ATOM feeds. This allows the incorporation of any system capable of responding to such feeds. Alerts may easily be posted to websites, Facebook, Twitter as well as many existing systems. All servers have a high availability option.

How many IP telephone speakers can simultaneously receive a public address announcement from a VE6023 Telephone Paging Server? The number of phones is controlled by the license that was preinstalled when the server was purchased. Other than that, there is no hardcoded limit on the number of IP phones that can be paged by one VE6023 Telephone Paging Server. The server will run through its database of phones and send the activation message to each one. When all the phones have been contacted, then the audio is sent over the network. Having said that, though, there may be reasons why a single server may not be the best option. When the VE6023 was designed, we tested the time to send activation commands to 10,000 IP telephones under ideal network conditions. It worked out to about one second per 1000 phones. So, that would extrapolate to be 16 seconds for 16,000 phones, etc. The end user may decide that waiting 16 seconds is too long (especially for an emergency message) and may want to put additional VE6023 Telephone Paging Servers in place to expedite the setup time. Your network speed, traffic and design will dictate the real setup time for the paged phones. Engineered, Built and Supported in the U.S.A.

There could also be structural reasons due to the way the network is designed. If there is a location that would have the bulk of the paging activity, and the network connectivity to that location is not as robust as it could be, then you may decide to put a local VE6023 there to keep the traffic within the local area. For another example, you may want to have more than one VE6023 server for the redundancy value. In most cases, after the phones are individually set up via unicast, the audio stream to the phones is sent via multicast. There is an option to page to the phones via unicast audio to each phone. If the network requires the unicast option, then realistically, you probably will only be able to page about 500 phones per VE6023. The good news is that practically nobody has that limitation on their network. So, you see that there are various ways to setup an installation that take into account the customer's infrastructure and the way they want to use the system. The system can also be expanded later if necessary. If one server was installed and it did not provide adequate performance, then additional VE6023 Telephone Paging Servers could be added and the phones subdivided between the servers to share the load. As for other needed equipment, there does need to be a source for the paging audio. For live voice paging, you need some way for the user to make a call and make the announcement. One option is a VE204A, which can provide up to 100 paging groups when connected as a SIP trunk on the IP Telephone System. Another option is a VE8014AR FXS Gateway, which connects to an FXO port(s) on the IP telephone system. This FXS Gateway allows practically unlimited page groups but does require the customer to have at least one available FXO port.

If classrooms have telephones, why would I need a call button? First, call buttons are very inexpensive and the spare wire pair to support them is typically available in the multi-pair cable connecting the classroom to the wiring closet. They are not an expensive addition to an intercom system. But why even add them? There seems to be a trend in the school intercom market where call buttons are removed from RFPs, and then they reappear. The logic seems to be that if there is a telephone in the classroom, then there is no need to have a call button as the teacher can use the telephone to call the office. Schools that do not install call buttons, quite often add them after the fact. Here’s 4 reasons why: 1) If a student becomes violent, they can easily disable the telephone (tear it out of the wall) to prevent the teacher from calling for help. A call button is much more difficult to disable or vandalize. As a matter of fact, a call to the office would most likely be initiated in the process. Once a call button is pressed, there is no way to

Engineered, Built and Supported in the U.S.A.

P a g e | 17

cancel, or disconnect, the call from the classroom. The call ends when the called administrator hangs up the phone. 2) If a student is in a situation where the teacher needs to be by their side (medical condition, injury), then any student can call the office by pressing the call button and the teacher can converse from anywhere in the room. 3) If the teacher becomes incapacitated, perhaps due to a medical condition or violence, will students know how to call the office for help? Pushing a call button takes no training. 4) If the phone system fails, having a call button on the intercom speaker ensures that the teachers will still have full communication with the office should a crisis situation occur.

What is the suggested cable type to use for Valcom Self Amplified Speakers? Are there limits? “Limits” is such a strong word. With a proper design, there really are no “limits”. One of the many benefits of Valcom Self Amplified Speaker Technology is the ability to use inexpensive UTP cabling. There are 2 pairs required for each cable run, one for dc voltage and one for audio. In order to minimize cost and maximize benefit, the dc power supplies should be located in IDF closets close to the speakers they are powering. A cable run may connect multiple speakers.

Why do I need synchronized clocks? Synchronized clocks provide a single time standard for a facility and save money by coordinating work schedules, break times, meetings, class changes. They are easily coordinated with a facility’s public address system such that reminder tones, like class change tones, may be implemented to manage the daily activities of employees, students and staff.

What is the best method to correct synchronized clocks? The best method depends upon the application. For new VoIP installations, IP clocks are the best choice. They are easily deployed on the facility’s LAN and are powered and synchronized through a single network connection. Even our IP clock/speaker combinations only require a single network drop. IP clocks are automatically updated following time changes. 2-wire digital correction is also a great choice. This correction protocol features the ability to power and instantly update the clocks over a single pair of UTP in a non-IP environment. 2-wire digital clocks may be wired in parallel so that one cable pull serves multiple clocks. Battery operated wireless correction clocks have the obvious advantage of quick deployment without the cost of cabling. Replaceable, readily available D-cell batteries can last up to 7 years. Wireless correction clocks may also be locally powered for a completely maintenance free deployment.

What’s the difference between regular Valcom talkback speakers and Class Connection ES talkback speakers? Due to the potential capacity of a Class Connection ES system vs. a lesser capacity talkback system, we designed the system to make balancing easy. The talkback speakers specified for use with Class Connection ES systems have provisions to tailor the sound Engineered, Built and Supported in the U.S.A.

level to the area of coverage. In other words, it’s easy to make the speakers quieter or louder depending upon the room that they serve. This approach makes future maintenance easy as all of the custom audio levels are set at the room level. You can use any Valcom Talkback speaker with Class Connection ES as long as you add a volume control or use a call switch with integrated volume control along with the speaker.

You offer several different attenuators/volume controls, can you explain the differences? V-LPT Impedance Matching Module The V-LPT is designed to connect to 45 Ohm system speaker outputs. It attenuates the speaker signal level (≈ 7vrms) to line level audio (≈ 245mv rms) and lowers the output impedance to 8 Ohms. It can provide one-way audio to up to 150 Valcom Self Amplified Speakers or can feed line level audio into an old fashioned 25/70.7/100 volt amplifier. Although it includes a trim pot for fine tuning the signal, it is really designed to be setup during installation and is not for daily adjustment. V-1092 Wall Mount Volume Control The V-1092 is a single gang passive (non-powered) volume control for line level audio sources. It is designed to be adjusted as often as necessary. It is a very useful addition to speaker lines serving speakers or horns that will be difficult to access after installation, speakers in individual offices or meeting rooms, or zones consisting of multiple speakers in a common area like a cafeteria or hallway. The V-1092 features a stainless-steel plate and fits a single gang electrical wall box. V-1094A Page Port Preamp/expander The V-1094A is a single gang active (powered) volume control/preamp for line level audio sources. Although not typical, it is designed to be adjusted often if necessary. It boosts signal on line level audio lines reaching capacity and provides an 8-ohm output to drive up to 150 additional Valcom Self Amplified Speakers or horns. The V-1094A features a stainless-steel plate and fits a single gang electrical wall box. VMT-1 Impedance Matching Transformer The VMT-1 provides an impedance match between a 500-600 Ohm balanced line and a high impedance auxiliary or Hi-Z microphone input (typically of an old fashioned 25/70.7/100 volt amplifier). It may also be used to attenuate the audio output of an old fashioned 25-volt amplifier to line level audio (Although the V-1095 is preferred for this application). Refer to V-1096 for line level to lo-Z microphone level.

V-1095 70 Volt Expander The V-1095 may also be used to attenuate the audio output of an old fashioned 25/70.7/100 volt amplifier to line level audio. The V-1095 features a stainless-steel plate and fits a single gang electrical wall box. It also features a volume control for fine tuning the signal. V-1096 Audio Interface The V-1096 provides an impedance match between a line level output and a Lo-Z microphone input. It features capacitive coupling to block DC supervision voltage. S-560 20-Watt Attenuator The S-560 permits changes to the audio level of 25 or 70.7 volt speakers and horns without altering the speaker wiring connections. Tap the speaker for the maximum audio level required and use the attenuator to change the volume level. The attenuator features a stainless-steel plate with embossed numbers and fits a single gang electrical wall box. The attenuator controls a 20-watt speaker load with a 10 position tap switch and operates on 25 or 70.7 volt speaker lines. The S-560 is also the attenuator of choice for 45-ohm talkback speaker circuits. Call Buttons with volume control There are several models of call buttons for 45-ohm talkback speaker circuits that feature integrated volume controls. V-2971 Normal call switch with volume control (Stainless Steel) V-2991-W Normal call switch with volume control (White Decor) V-2970 Normal/Emergency call switch with volume control (Stainless Steel) V-2995-W Normal/Emergency call switch with volume control (White Decor) These are designed to provide convenient screwdriver adjustment of speaker broadcast levels. When these are used, both the audio and call button pairs of the originating equipment terminate on the call button with volume control. A new attenuated pair is then routed from the call button/attenuator to the speaker. For maximum range, adjust the 45-ohm speakers being controlled to their highest volume level.

How many gateways, IP speakers and other endpoints can I have in an IP6000 system? Over 99,000. There is no practical limit to the size of an IP6000 system.

How many Valcom Self-Amplified speakers can I connect to an audio output of an IP Audio Gateway, page port or page control? When properly designed, there is no practical limit to the number of speakers.

What is IP paging and intercom? An IP intercom or IP public address (PA) system uses one or more TCP/IP networks to connect speakers and other support endpoints together. Being network based, IP intercoms/PA systems can be sized for any application and can provide coverage to one or many locations. These systems are primarily accessed through one or more telephones. The access telephones may be part of a telephone system or traditional POTS sets. A combination of both may be used in a single system. IP intercoms require telephone access for 2-way communication and usually have pushbuttons at the speaker locations to initiate calls. These buttons are often referred to as “call buttons”, “staff assistance buttons” or, in the case of emergency IP intercom stations, “emergency call buttons”. Pressing the pushbutton causes a telephone to ring, once it is answered, a 2-way (talkback) conversation is established between the person that pressed the pushbutton and the person that answered the telephone. The intercom conversation is “handsfree”, much like a speaker phone conversation and disconnects when the telephone user hangs up or releases the call. An IP intercom or IP public address system also uses telephone dialing to call different speakers or areas. Microphones do not support 2-way intercom conversations or dialing to call different speakers or areas. There are many speaker and horn styles from which to choose, all of which are conveniently powered and communicate over a single network cable (PoE). It’s common for systems to have both one-way and 2-way intercom speakers.

Do you have products for school intercom opportunities with existing analog speakers and clocks? We routinely modernize all types of existing systems. This is especially true of school intercom systems. Assuming that the existing cabling, speakers, call buttons, clocks are in good condition, we can provide either IP or analog retrofit equipment to facilitate the modernization of existing systems without the cost of full replacement.

Call us to discuss your specific application.

Do you offer speakers designed for higher fidelity background music applications? Valcom interior speakers are commonly used for background music. If your application requires higher fidelity (retail, lobby areas, etc.) then you may wish to select our Signature Series High Fidelity speakers which are designed to provide a higher frequency response.

Do you offer a 30-watt wall speaker? Wall speakers are designed for indoor areas. A 30-watt wall speaker would produce approximately 112 decibels of sound at 1 meter. Our one-watt wall speaker will produce approximately 98 decibels of sound at 1 meter, more than adequate for most indoor areas where wall speakers would be an option. Environments that would require 30 watts of audio power would require hearing protection and would be much better suited to the use of horns. Read more about the relationship between power ratios and sound pressure in the “Amplifier/Power Facts and Myths” section of our best practices document.

Do you offer bells for schedule changes? Mechanical bells for alerting students and staff of scheduled times are very limited in their functionality. All modern internal communication systems with scheduling capabilities use the system speakers to sound tones for breaks, lunch time, shift changes, class changes, etc. These same speakers are used for voice announcements, custom tones, intercom and emergency notification.

How can Valcom use 24 AWG UTP for speaker connections? Unlike old fashioned techniques where speakers are powered from a central location, Valcom provides power at each speaker. This modern approach provides may advantages. Since our audio pair simply provides audio signal, and not power, there is very little current flow in the cable. Therefore, the signal loss in the cable in negligible. Distributing the power for the speakers keeps dc voltage wire lengths short, which results in less wire resistance and again, negligible power loss.

Do you offer speakers designed for cleanroom applications? Our cleanroom speakers VIP-140A and V-1040A are designed to meet the special requirements of cleanroom applications.

How many network switch ports do I need for an IP6000 system? In a pure IP6000 system, every speaker, clock/speaker combination unit, horn, LED sign, gateway and server will require a separate switch port. This configuration provides the most easily managed, versatile solution. However, there are several alternative solutions that support the use of numerous analog speakers and horns from a single switch port. Therefore, the answer to your question varies by design and the level of analog integration. Systems managed by a facility’s IT staff are often pure IP6000 system designs simply due to the expertise of those who will be administering the system.

How are Valcom IP endpoints configured? Most are easily configured with the VIP-102B IP Solutions Setup Tool. The VIP-102B discovers all routable Valcom endpoints and allows easy assignment of IP addressed, dial codes, group membership, NTP source, etc. It features many diagnostic and copy functions to assist with your setup. Install the latest version of the VIP-102B Valcom IP Solutions Setup Tool on a Windows based PC that is connected to the VLAN and perform a system scan. Verify that all the installed endpoints are discovered by the VIP-102B. A video example may be found here, a reference manual may be found here and Best Practices can be found here. There is also a Valcom IP Setup Tool which is used to change the IP address on Class Connection ES VECPU5 boards, MultiPath V-CPU-4 boards and VERCA boards.

How can I provide SIP access to a non-SIP compliant Valcom endpoint? Some products do not inherently support SIP due to their large capacity and the impracticality of using a SIP license per zone or station. Using Valcom protocol does not require per endpoint licensing. So, how do we use a SIP identity to route to Valcom protocol? It’s easy to use one or more VE802X FXO gateways, which are SIP accessible, to provide a “bridge” from a SIP phone system to a VE801X FXS gateway to access internal Valcom dial tone. Users simply dial an FXO gateway’s SIP identity, then the FXO gateway goes off-hook on the FXS gateway and users receive Valcom dial tone. In this way, a single SIP identity can access thousands of zones.

Can you provide a riser diagram for an IP6000 system? That is a good question. There is no way to make a one-size-fits-all riser diagram for an IP6000 system. Each system is comprised of individual IP endpoints designed to meet the specific requirements of an application. In a pure IP system, the riser diagram would consist of the network infrastructure connected to the IP endpoints in each physical location. The endpoints might be speakers, IP LED signs, FXO gateways, FXS gateways, Application Servers, audio gateways, or other endpoints. There is no official headend. This topology is what makes Valcom IP systems so robust. There is no single point of failure.

How do I implement SIP protocol with a Microsoft Lync® platform? A mediation server may be used to facilitate SIP access from a Microsoft Skype for Business (Lync) system. Although we do not endorse one brand over another, one well known choice of mediation server is AudioCodes' Enterprise Session Border Controller (E-SBC).

I am installing a Class Connection ES system for a campus style school, what is my best design option? It’s expensive to install cabling between multiple buildings in a campus style school environment. In addition, cables routed outdoors are often more susceptible to lightning damage. Fortunately, Valcom Engineered Solutions offers the perfect resolution to this problem. We offer several products that allow the deployment of analog station cards over a data network. All speaker, call button and synchronized clock connections can then be terminated within each building. This topology can save a significant amount of cabling, trenching and labor cost.

What’s a cost-effective way to mix stereo line level audio to a single monophonic output? Our V-9130-W is passive single gang mixer. It features both left and right RCA connections and a 3.5mm input. 2 screw terminals on the back provide the monophonic line level audio output.

Is there a way to connect multiple IP6000 sites together without enabling multicast on our WAN? Our VEUTM Unicast/Multicast Converter may be used to encapsulate multicast traffic in unicast packets for transport over unicast only network segments. One is typically required at each site.

Can I provide a system that automatically monitors itself? There are many techniques for providing redundancy and supervision. For example, wiring speakers in common areas such that adjacent speakers are sourced from different wiring closets, amplifiers, power supplies and audio outputs insures the continuation of audio coverage should one system component fail. Engineered, Built and Supported in the U.S.A.

P a g e | 26 As far as equipment supervision, we do offer products that provide automatic supervision. Our IP6000 system endpoints inherently report their routabilty to report basic network routing issues to our VIP Status Monitor Software. Class Connection ES VETCS Supervised station cards monitor call switch cabling via a 12K ohm end of line resistor and report faults via syslog, contact closure or in the Class Connection ES Administrator Software. Class Connection ES also provides system card fault detection and reporting. It’s also notable that our Application Servers all offer an optional “High Availability” mode with automatic failover.

What type of licensing is required for your IP endpoints? At this time, Valcom Servers are sold with a onetime, non-recurring license as part of their initial purchase price. Valcom IP speakers and gateways do not require any licensing unless they are accessed via Session Initiation Protocol or Singlewire® (formerly Informacast) protocol. To use the speakers and gateways with InformaCast® broadcasts would require Singlewire® IP Speaker licenses (acquired directly from Singlewire®). Be aware that Informacast® compatible products are not directly compatible with Valcom protocol and use unique Valcom part numbers (typically a -IC suffix) If using SIP for the talkback function of the speaker an endpoint license (Typically a "Third-Party SIP Device (Basic)") would be required for each speaker.

How can I add horns to a maxed out, old-fashioned, 70-volt system? You could mean that the load on the existing amplifier has reached the amplifier’s power capacity, or you could mean that the cabling on one or more runs will not adequately support any more horns. You cannot compensate for inadequately sized cabling by choosing a higher capacity source. Having an adequately sized source (amplifier, power supply) and having adequately sized cabling are equally important, yet unrelated, design criteria. Fortunately, there is an easy solution for either scenario. Simply add a Valcom V-1095 70 Volt Expander, up to 150 Valcom self-amplified horns/speakers, and simple dc power supplies. The V-1095 allows expansion of 25/70.7/100 volt speaker lines without loading the existing amplifier. As a huge bonus, the new Valcom speakers and horns can be connected using UTP cabling!

Do you offer horns for areas requiring explosion-proof equipment? Yes, we offer one way self-amplified, 45 Ohm talkback and 70.7 volt explosion proof horns.

Do you offer cleanroom rated speakers? Yes, we offer both one way self-amplified and IP cleanroom speakers.

Do you have any design recommendations for reverberant areas? Reverberation is repeatedly perceiving the same sound 2 or more times. Artificial reverberation is commonly added to music as a desirable “concert hall” audio effect. Too much reverberation, however can be quite detrimental to voice public address announcements. Natural reverberation is caused by sound reflecting off non-absorbent surfaces. In the audio industry, the term RT60 is used to quantify reverberation and is the time that it takes for the audio level, or sound pressure, of the original sound to diminish by 60 dBspl. RT60 is the result of the sound frequency, sound absorbency and surface area of the physical barriers encountered by sound pressure. High frequencies have shorter wave lengths and are absorbed more quickly. Lower frequencies tend to bounce around a bit longer. If all the reflections are quickly absorbed, then reverberation is not perceptible. (see Haas Effect). In areas with very reflective surfaces, such as non-porous concrete, RT60 can be quite high. So, in simpler terms, if you put too much loud sound into echoic areas, there’s a good chance that you will have issues with reverberation. How do you combat this? The ultimate answer is to acoustically treat the area. There is a whole science devoted to adding the right sound absorbent materials to an area to combat reverberation. This can, however be impractical and expensive for many applications. A more practical approach may be to use a single point of sound. The idea behind this approach is that a single point of sound (a single horn or a single array of horns) will minimize the reflected sound as there is only one source of direct sound to reflect. You see this approach in many sports arenas and concert halls. Many times, an area is both reverberant and loud, so a single point of sound is impractical. A good approach in these areas is to have many points of sound, all pointing straight down so their sound encounters the first reflective surface (the floor) simultaneously and therefore the reflected sound is in phase and, theoretically, diminishes in phase. In practice, this is never a perfect approach, but it’s better than bouncing sound off different surfaces at different times. Another advantage here is that by directing the sound sources (horns) straight down, the volume of each can be turned down to a level just high enough to cover the area directly below. This minimizes the initial sound energy that will need to diminish and effectively shortens the perceived RT60. A light analogy works well in describing reverberation minimization techniques. Picture a room with mirrors covering all surfaces, floor, walls and ceiling. You are tasked with evenly lighting this room. You would not want to use bright spotlights pointed in different directions as they would reflect off different surfaces and randomly scatter the light. Where reflections crossed paths, the light would appear even brighter, just as intersecting “in phase” reflected sound would create uneven loud spots, and out-of-phase reflected sound would create “dead” spots.

Engineered, Built and Supported in the U.S.A.

P a g e | 29 One light, could possibly be used, as the mirrors would help to spread the light. If the room was large, however, the one light would have to be rather bright, too bright for those nearby. Many lights, directed straight down and dimmed such that they evenly lit the area just below, would provide an adequate evenly distributed solution. If our mirrored room had one surface that was not mirrored, then directing all the lights toward this surface would be a good solution. Likewise, in the rare case where a reverberant area is open to the outside, pointing all the sound sources towards this opening, would minimize the reflected sound. Also, keep in mind that the contents of an area will absorb or reflect sound. An empty warehouse may have a high RT60. When the warehouse is filled with boxes and people, the RT60 may be reduced significantly. These dynamically changing environments can be especially challenging. Fortunately, a heavily occupied area is also often a louder area. Valcom automatic volume controls are often incorporated into designs involving dynamically changing areas to minimize the horn sound energy, and therefore the reverberation, when the area is quiet. How much RT60 is acceptable? Many agree that acceptable times are dependent upon room size and sound frequency. In very general terms, up to 1.5 seconds is an acceptable RT60 for voice paging1. RT60 (in Seconds) <1 1 – 1.2 1.3 – 1.5 1.6 – 1.7 1.8 – 2.0 > 2.1

Notes Announcements have exceptional intelligibility Announcements have exceptional to good intelligibility Announcements have good intelligibility Borderline Intelligibility – use special layout techniques previously discussed Use direct sound where required (spot paging) Intelligibility is difficult or impossible to achieve

A simple test for RT60 during a site survey is to sound a portable canned air horn and time how long it takes for the sound to diminish.

What are some options if an area is too reverberant for voice paging? If acoustic treatment is not an option, then using a combination of alert tones through horns and text on LED signs to disseminate information is an effective alternative to voice paging for loud or reverberant areas. Spot paging, placing horns in specific locations such as break areas, immerses close listeners in direct sound such that the effects of the reverberation are minimized. 1

I see that your Application Servers offer secure shell communications. How do I get a SSL Certificate? We provide two options to make use of HTTPS. To use HTTPS, you must have a valid SSL Certificate. One option is generating a self-certified SSL Certificate and the other to purchase one from a third party. To use the self-certified SSL Certificate option you can go into the server web interface and generate one there. Otherwise you must purchase/update a SSL certificate from a third party, (which may eventually expire). Either way, both options are handled in the HTTPS Configuration menu. As an example, in the VE6024 eLaunch server: 1. Browse into the server and navigate from the main screen by selecting Advanced>Administration->Settings->HTTPS Configuration. 2. Check `Enable HTTPS`. 3. To enter a new third-party certificate check `Install new certificate`. You can then select the third-party certificate files to upload them to the server. OR 3. To use a self-signed certificate, check `Generate self-signed certificate`. You can then fill in the information in the box below the checked circle.

What are some of the advantages of using unshielded twisted pair cabling? Valcom capitalizes of the use of unshielded twisted pair cable. Highly reliable UTP was developed for the telephone and networking industries. There are many advanced cable management and connectivity options for UTP such as 110 and 66 blocks. In addition, many cable manufacturers offer long term warranties on their UTP products. UTP, when used with differential signals and inputs provide inherent noise rejection and help to minimize the effects of capacitance between adjacent pairs. These advantages are explained here.

I need to provide audio to an old-fashioned amplifier. How much input signal do I need? Audio inputs have a “sensitivity” rating. This is the amount of audio signal that is required for the amplifier to deliver full rated output to its rated load. The source must be able to deliver the required amount of audio signal and the source output impedance will be at least 10 times less than the amplifier’s input impedance. If the source’s output impedance > the amplifier’s input impedance, then less than half of the available signal can be delivered from the source to the amplifier. If the source’s output impedance = the amplifier’s input impedance, then only half of the available signal can be delivered from the source to the amplifier. If the source’s output impedance < the amplifier’s input impedance, then more than half of the available signal can be delivered from the source to the amplifier. Theoretically, ideal audio signal sources have zero output impedance and ideal audio signal inputs have infinite impedance (these do not exist). Proper transformers may be required to adjust the impedance ratio and to provide isolation and balance between the source and the input. Providing too much audio signal into an amplifier will result in clipping of the signal and ultimately audio distortion or damage.

Is there an advantage to choosing multiport audio gateways over single port audio gateways? Valcom offers our FXO, FXS and audio gateways in 1, 2 and 4 port models. The model(s) you choose will be based upon how many ports you need at any given location. For example, if you have 6 zones of audio originating from one specific distribution frame, you might choose: 1-Port Audio Gateway 6 0 0 0

2-Port Audio Gateway 0 3 1 0

4-Port Audio Gateway 0 0 1 2

Total Audio Ports 6 6 6 8

Total PoE switch ports required 6 3 2 2

By choosing two of the 4-port Audio Gateways, you end up with 2 ports for future expansion while using use a minimal number of PoE switch ports. The cost difference between a 2-port + a 4-port Gateway and two 4-port Gateways is minimal.

I am designing a public-address system and the specifying authority has dictated that we use a very specific amplifier. I don’t think it’s the best solution, or can even meet their needs. Can you help? Our products are best suited to applications where decision makers are more interested in meeting or exceeding the needs of the facility than in specifying the exact equipment to do so. If we are bound by a list of pre-selected equipment, we have limited options. Given a list of feature and system requirements, we find a great solution 99% of the time. If the specifying authority is open to a better solution, we’d love to speak with them. This is the only way to make technological progress. Otherwise, old specs perpetuate old solutions for eternity.

Why is it important to know the ceiling height and type when choosing ceiling speakers? Assuming that ceiling speakers are an appropriate option for the area, the answer is simply to ensure that the speakers selected will be suitable for the architecture of the room. For example, you probably wouldn’t want to use 2’ x 2’ ceiling tile lay in speakers if the area had 1’ x 1’ ceiling tiles, or no ceiling tiles. The mounting height determines if the speakers will be flush mounted or will be suspended in some fashion. The mounting height also dictates the quantity of speakers required for the area. Sometimes, if the ceiling height is too high, alternate mounting locations, like structural beams may provide a more suitable mounting height. Ambient noise level also plays an important role in speaker selection. Choosing the best speaker/horn option requires room details.

I know very little about IP paging solutions, can you provide a broad overview? IP paging technology is very simple. It is often considered to be much easier to deploy than analog solutions. In a pure IP deployment, every speaker connects to a properly configured IP network. This is the most common topology used and inherently supports unlimited system capacity for district wide, county wide, city wide, etc. communication systems. We have systems deployed in small private schools and we have systems deployed that span continents. You are only limited by the ubiquitous reach of the IP network. Automated scheduled audio such as tones and music, are facilitated by the addition of a browserbased Application Server. These tones and audio feature full customization and can be virtually any sound that you can imagine.

P a g e | 33 Audio inputs and outputs are, of course, analog. Inputs may be line level audio from music players, voice into microphones, voice into/from dedicated public address/intercom telephones, or telephones that are part of an existing telephone system. Telephone access of multi zone systems is the preferred access method due to the ability to dial select speaker zones/stations. Telephone access of 2-way intercom systems is mandatory so that users can participate in both sides of the conversation. And, of course, people are comfortable with telephone use for 2-way conversations. The speaker end of the 2-way conversation is hands free and operates much like a speakerphone. In a full IP deployment, audio outputs may be sound from IP speakers and/or the speakers that are integrated into many IP telephones, In hybrid deployments, those that use non-IP speakers, audio outputs may be audio from gateways that source 1-way amplifiers or self-amplified speakers*. To facilitate 2-way intercom communications. audio outputs may also be from "2-way" Talkback Intercom Gateways that connect to either 45-ohm* or 25-volt interior speakers. Both IP speakers and "2-way" Talkback Intercom Gateways are available with provisions for "call for assistance" buttons located near the speaker such that 2-way intercom calls may be initiated from the speaker location (think classroom) or from the telephone location (think office). The above is a very simplistic overview of what is possible. It's not uncommon to have 2-way talkback IP clock/speaker combinations in classrooms, while hallways and other common areas are served with audio gateways sourcing audio to 1-way self-amplified speakers or to old fashioned central amplifiers. The General Public Address and Intercom System Design Guidelines document goes into much more detail. If you view the document as a PDF, you may want to explore the many informative hyperlinks embedded in the text and some of the graphics, *Self-Amplified 1 way speakers and horns as well as 45-Ohm 2-way Talkback speakers are preferred for many reasons, not the least of which, is their ability to connect via unshielded twisted pair category 3/5/6 cable.

I have an opportunity to retrofit an existing intercom and public address system. What do I need to consider? Retrofits are very common and are easily accomplished using either IP or analog equipment. The most important thing to understand is that the customer is requesting the upgrade for a reason. If the troubles that they’ve experienced in their existing system are related to the speakers, call switches, amplifers and wiring that you plan to reuse, then replacing the main headend equipment will likely not provide the desired results. We discuss this topic is detail in our General Public Address and Intercom System Design Guidelines.

What should my company contemplate when planning emergency messaging? First, consider what types of emergencies you might encounter. For example: 1) 2) 3) 4)

Active Shooter Severe weather event Hazardous material spill/leak Bomb threat

For each emergency message: 1) Who should be notified? a. How should the notification be delivered? i. Voice announcement? ii. Email? iii. Social Media? iv. 2-way radio? v. LED Signs? vi. Phone call? b. What should they do when they are notified? i. Evacuate? ii. Take Shelter? iii. Operate emergency equipment? 2) Who should be able to initiate the notification? a. Security? b. Management? c. Anyone? d. Public authorities? e. Automated process? (boiler over temperature switch, etc) 3) How will the notification be initiated? a. Telephone? b. Panic Button? c. 2-way radio? d. Browser interface? e. Smartphone app? f. From an automated process? 4) How will people be informed when the emergency is over?

What’s the recommended approach to managing flexible IP groups? The VIP-102B IP Solutions Setup Tool allows the creation of multiple groups. These groups are each assigned a unique dial code and are used for a myriad of purposes including: a) b) c) d) e) f)

Making voice announcements Sending text messages to LED signs and computer screens Creating Audio Events to send audio to specified speaker locations Directing streaming audio to specified speaker locations Creating audio recordings Triggering Play Lists

A highly-recommended method of group management is to create unique groups for each function. This method allows for easy long-term audio and text distribution management. For example: A typical facility will have a group that includes all speaker locations. This is commonly referred to as “all call”. This solitary group could technically be utilized to distribute automated announcements, audio files, general announcements, text-based messages, emergency announcements, scheduled audio events and music. However, by only having one “all call” group for all purposes, there is no flexibility to modify the group destinations for any one purpose. By alternatively creating individual groups for each purpose, and logically labeling them for easy identification, users can easily change the audio or text distribution for one function without hindering the others. Managing Groups Text and audio distribution management is accomplished by creating a solitary group for every unique combination of endpoints that will simultaneously receive audio or text. This would include logical combinations of: a) b) c) d) e) f)

Speakers and horns Audio gateway output Phone speakers Computers (for pop up alerts) LED signs IP telephone screens

Most users find it easier to manage these dedicated “bell tone” groups, “phone speaker groups”, “LED sign groups” and “computer screen pop up groups” as opposed to using the same groups for all functions. Engineered, Built and Supported in the U.S.A.

P a g e | 36 Groups are unrestricted and endpoints/endpoint channels may be members or any or all groups. As an example, you might have 3 individual announcement audio groups for the 6th, 7th and 8th grade classrooms, however, if there will be scheduled events that exclusively go to all 3 grade levels, building a “bell tone” group including all 3 makes future schedule management much easier. Name these with a unique prefix, perhaps “B” for bells and “A” for audio announcements, “P” for phone groups, “S” for LED sign groups, and “C” for computer screen notification groups so that they are easily identified.

Dial Code 020 026 027 028 021

Group Name A Everywhere A 6th Grade A 7th Grade A 8th Grade A 6th, 7th, 8th

Priority 40 40 40 40 40

010 011

B Everywhere B 6th, 7th, 8th

50 50

Following these guidelines will simplify schedule creation and management by facilitating ad hoc modification to single schedule event groups without sacrificing the functionality of groups used for other audio distribution, such as live announcements.

What are options for interfacing to an existing master clock? The answer is dependent upon the Valcom equipment you are using and the capabilities of the existing master clock. In general, Valcom head end equipment can accept a contact closure from an existing master clock to either reset our internal time or actuate a tone. In many cases, we can alternately provide a contact closure to sync the existing master clock or take over the functions of the existing master clock altogether.

What solutions do you offer for acoustic feedback prevention? Common techniques to overcome acoustic feedback include: a) Building separate groups to exclude speakers and horns near page initiation stations. b) Adding Valcom Feedback Eliminator(s) to delay announcements until you hang up the page telephone. c) Using Valcom Application Servers to delay announcements until you hang up the page telephone.

What are Valcom “Power Units”? To simplify power supply selection, Valcom Self Amplified Speakers and some Valcom Controllers are rated in Valcom Power Units (VPU). The power units required for each product, if any, can be found in the product manual, the product catalog or on the Valcom website. Products that require power have a negative VPU rating and products that provide power (power supplies and some controllers) have a positive VPU rating. The resulting sum of the VPUs between power supplies and the products that they are powering must simply be => zero. It’s simple addition and subtraction, no complex power formulas are required. Power supplies are independent of speaker zones, so one supply can power speakers in many zones.

In the example shown, the V-2006A Page Control unit has a convenient 30 VPU power supply built-in. 22 of the V-9022A Lay In speakers (1 VPU each) and 2 of the V-1030C 5-Watt horns (5 VPU each) will be powered from this location. +30 – 22 – 20 leaves a deficit of 12 VPU. We would simply choose a Valcom power supply that could provide at least 12 VPU. Note - If the power supply selected has multiple outputs, plan combinations of products that will connect to each output so as not to exceed capacity. For example, a 6-amp power supply (120 VPU) has 3 outputs each rated at 40 VPU. If you were powering 4 speakers that required 12 power units each, then 3 of the speakers (3 x 12 = 36 VPU) would connect to one of the 40 VPU power supply outputs and the other speaker would connect to a second 40 VPU power supply output. Do not bridge outputs.

I am installing an IP based system with 618 ceiling speakers, 134 wall speakers, 52 horns and 26 clocks. What accessories will I need? Suggested accessories for a system cannot be determined by speaker types and counts alone. Details of the installation are also required. Some examples are listed below: Product Round Ceiling Speaker Lay in Ceiling Speaker Horns Clocks

Installation Detail Round ceiling speakers may require bridges and backboxes, bridges without backboxes or support rings. In some cases, they may also require clock speaker baffles or square surface mount enclosures. We need to know the type of surface and environment in/on which the speaker will be installed to assist in accessory selection. Lay in Speakers are designed to replace a ceiling tile. They are available in Imperial measurements 2’ x 2’ or metric measurements 600mm x 600mm and do not require any accessories. Horns may require protective wire cages (guards) if they are in areas where damage from vandalism or unintentional ball strikes are possible. Clocks may require protective wire cages (guards) if they are in areas where damage from vandalism or unintentional ball strikes are possible. They may also require clock speaker baffles or 2-sided mounting brackets in certain applications.

Can you cross reference another manufacturer’s equipment list? We are often asked to cross reference equipment lists and provide a Valcom equivalent. If the equipment list consists solely of commodity items like old fashioned centrally amplified speakers and their corresponding amplifiers, then cross referencing is typically an easy task. If the equipment requested includes products to provide advanced features, or if the equipment is intended to operate as part of a bigger application, then providing us with details such as the desired features and intended operation will allow us to meet or exceed your expectations. Mandating that a comparable part-for-part equipment list be offered limits the ability to provide better options. We provide complete solutions. As such, we may not offer line item replacements for other manufacturer's parts and pieces. Our approach to deploying PA/Intercom/Emergency Mass Notification solutions is most often superior to what is requested via published specifications. Our design guide may be used to help you provide the information that we will need to provide the perfect solution.

Do you offer horns for areas requiring explosion-proof equipment? Yes, we offer one way self-amplified, 45 Ohm talkback and 70.7 volt explosion proof horns.

Do you offer cleanroom rated speakers? Yes, we offer both one way self-amplified and IP cleanroom speakers.

What solutions do you offer for heavily used PA systems? Public address systems that are in near constant use, like those in hospitals and airports, typically benefit from multiple system access paths and page stacking. Page stacking is a solution that records and queues announcements. Both Feedback Eliminators and Application Servers feature page stacking capability.

How can a Valcom system be integrated with my existing PA/Intercom? The most common integration is for the Valcom system to provide audio signal to the existing system. The usual methods would be: 1) Connect an audio output from the Valcom system to and audio input on the existing system. a. The audio may need to be reduced or boosted depending upon the input selected b. A matching or isolation transformer may be required c. If the existing system has multiple inputs, the input selected must provide the priority required for your application d. A control relay may be required from the Valcom system 2) The Valcom system automatically dial selects, and broadcasts to, a channel/zone on the existing system.

How can I adjust the volume of Valcom Speakers? Very easily, however, the specific answer depends on the speaker and system type. One-way self-amplified speakers/horns all feature convenient integrated volume controls. Typically, we recommend that installers initially set these integrated volume controls all to 1/2 volume. In many cases, the baseline volume may then be adjusted by the originating system or gateway. Finally, individual speaker/horn volumes may be adjusted up or down on a per area basis. Wall mount volume controls may be added for convenience. This may be an advantage for zones with many speakers/horns or with speakers/horns that are difficult to access. Some 45-Ohm talkback speakers have integrated volume controls, some have volume presets determined by which input is used to connect the audio feed to the speaker (high, normal, quiet, very quiet), some have no integrated means of controlling volume and simply rely on the audio level provided by the originating system. IP speakers/horns – the baseline volume is adjusted in the VIP-102B’s channel tab for the speaker/horn. Offsets from this baseline are available based upon one-way audio group priority and often, in the gateway or server originating the audio. For example, audio groups intended for emergency announcements may be programmed to provide higher volume audio than a normal zone/channel specific announcement. Likewise, the volume level of specific Application Server originated audio events, like bell tones, may be individually tailored to owner preference. There is a simple volume balancing procedure described in the network requirements document. It may be found here. Note that there are also channel volume controls on originating FXO and FXS gateways which should be left at default unless one telephone-based source characteristically provides lower volume (i.e. both a POTs single line phone and an FXO port are connected to the system, but one of these provides lower audio than the other).

Are Clarity® Brand 25-volt speakers one-way speakers or two-way talkback speakers? Both. Any voice coil speaker can be used as a one-way or two-way speaker. The ability to talk back is determined by the equipment to which the speaker is connected. The quality of the talkback signal is related to the size of the speaker cone, the ambient noise level in the speaker location and the level of voice that reaches the speaker. 8-inch speakers are a common choice for producing good quality talkback signal.

We’ve opted to build a parallel network for the Valcom IP6000 system. How can we allow users on the facility network to browse into the system Application Servers? A router may be added to route TCP/IP traffic between your dissimilar networks. As far as system adds/moves and changes, for full functionality, the PC hosting the VIP-102B IP Solutions Setup Tool would connect to a port on your multicast enabled parallel network during maintenance. However, if the PC hosting VIP-102B is routable to the Valcom endpoints, and the devices’ IP addresses are defined in the network settings of the VIP-102B, the PC may be connected on the facility network (multicast not required). From this network vantage point, however, you would not be able to add new devices or use network diagnostics/paging diagnostics.

Do you provide speaker layout services from floor plans? Determining speaker/horn type and spacing based solely on floor plans is a risky endeavor. There are many variables that affect such decisions. The presence or magnitude of these variables are impossible to ascertain without firsthand knowledge of the target environment. Avoiding the liability that would result from making assumptions requires firsthand knowledge of the site obtained through a site survey. We do offer guidelines and site survey forms to assist you in gathering the information you’ll need to perform a successful site survey and to accurately determine speaker/horn quantities per area. Once you’ve made this determination, we will gladly assist in product selection. Remember that the solution that we suggest can only be as accurate as the information that you provide.

How much does twisting pairs of wire increase effective AWG size? If you twist two wires together, each would carry half the current, so you effectively increase the gauge. American Wire Gauges go down by about 10 for every factor of ten in crosssectional area. If you had ten 20 AWG wires connected in parallel, they could effectively carry as much current as one 10 AWG wire. With two 20 AWG wires, you'd have the equivalent of one 17 AWG wire. Smaller AWG = larger conductor size = more cross-sectional area = less resistance for any given length. Some "rules of thumb”: 40 AWG copper wire has about an Ohm of resistance for each foot. By the rule above, 30 AWG copper wire would have an Ohm of resistance for every ten feet, and 20 AWG an Ohm of resistance for every 100 feet. Combining 2 conductors of the same AWG wire will result in a drop of 3 AWG size increments (two 24 AWG conductors combined = one 21 AWG conductor) Combining 3 conductors of the same AWG wire will result in a drop of 5 AWG size increments (three 24 AWG conductors combined = one 19 AWG conductor) Note that connecting wires in parallel may work at dc or low frequency ac, for audio, RF, or other purposes, it’s best to use a single pair.

The Valcom V-Alert app is the fastest way to notify large numbers of people that are located over a large (or small) geographical area. Much faster and much more reliable than SMS, the V-Alert delivers information instantly with minimal effort.

What makes Valcom stand out? When asked what makes Valcom stand out, we find it impossible to choose one answer. 1) We are proud innovators. a. We invented self-amplified speaker technology that is now the standard of most government, industrial, educational, healthcare and commercial institutions. Why? Self-amplified speakers feature highly efficient, integrated point-of-sound amplifiers and therefore connect with inexpensive, modern UTP cabling. Unlike old-fashioned 25/70.7/100-volt amplifier-based systems, there is no single source audio blocking and adjusting audio levels is as easy as turning the built-in volume control. b. We started offering VoIP speaker products and endpoints during the infancy of VoIP technology. Today we are offering our 3rd generation of VoIP speakers, horns, feature servers, FXS and FXO gateways. We utilize industry standard session initiation protocol (SIP) and our own feature rich protocol and often use both in the same systems. c. We design and build 95%+ of the products we offer in our state-of-the-art manufacturing facility. Having our own in-house electrical/mechanical/software engineering groups, metal fabrication and production facilities allows us to provide rapid response to our customers’ requests. d. Our competitors follow our lead. 2) We are international friendly. We have installations in the Middle East, Europe, Asia, North and South America and many other regions of the world. 3) We are problem solvers. We pride ourselves on finding new and innovative ways to satisfy the needs of our customers. 4) We are obsessed with customer service. This is mandated from the top of the organization. A mandate that we are honored to execute. We run towards customer concerns and work hard towards speedy resolution. 5) We provide choices. Other manufacturers provide a single local source for their products and service. We will work with any qualified integrator selected by our customers.

We are responding to an RFP for a school intercom that has classroom telephone handsets. Do you offer such a product? It is no longer typical to incorporate telephones as part of an educational intercom. Telephones that are part of intercom systems are very limited in functionality and capacity. We are one of the premier providers of internal communication systems for schools, industry, government, healthcare, transportation and retail facilities and have long abandoned such outdated solutions. Unfortunately, obsolete specifications are still issued in some places. In the rare case where this is desired, and full feature telephones are not already part of the classroom communication design, integrators will typically provide a separate telephone system along with a dedicated intercom. Our system can all be integrated with the facility telephone system for easy access.
