3. Description

After motion is sensed by the detector in the coverage area, the alarm relay contacts will open for 2 seconds.
Supervision features
In the event of the voltage drop below 9 V (± 5%) for more than 2 seconds or the signal path failure, the detector
will signal a trouble. The trouble is indicated by the activation of alarm relay and the steady light of LED
indicator. The trouble signaling will continue as long as the trouble persists.
Remote LED enable/disable
The LED can be enabled/disabled remotely, if the LED has not been enabled using the LED ON/OFF pins. The
LED terminal is provided to allow remote LED enable/disable. The LED is enabled, when the terminal is
connected to the common ground, and disabled, when the terminal is disconnected from the common ground.
