GD100 GD100 – Single Channel Detector The GD100 is a cost‐effective, single‐channel, din‐rail mounted, microprocessor‐based detector used to detect vehicle presence by means of an inductance change caused by the vehicle passing over a wire loop buried under the road surface. With front panel switches to allow for different loop frequency settings, sensitivity settings and mode settings, the GD100 is a compact, low‐voltage detector specifically designed for the Gate & Door market.
Applications
Parking barrier control.
Safety loop.
Arming control.
Motorised gates and doors.
Industrial control systems.
Specific Features
Compact Size: This compact industry‐standard housing combines all the requirements regarding features and functionality and allows this detector to be incorporated into any new or existing vehicle detection system.
Selectable Fail‐Safe/ Fail Secure: Allows a selectable output for either Fail Safe or Fail Secure operation.
Loop Isolation Protection: The loop isolation transformer provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops.
Loop Frequency Indication: The possibility of cross‐talk (interference) between adjacent loops/ detectors can be determined by a visual display, and eliminated by changing the frequency settings. Automatic Sensitivity Boost (ASB): Facilitates the reliable detection of all vehicle combinations and high‐ bed vehicles by boosting the sensitivity to maximum after detection of a vehicle.
