Understanding the LED when the detector 
is in operation 
The LED can have the following states in operation: 
•  Flashes 1 to 3 times when powered ON: Indication of 
range setting after power-on 
•  Off: Normal state, no alarms 
•  Permanently on: Intrusion detected – if detector in Latch 
mode 
•  Permanently on with 2 dips per 3 s: Low supply voltage or 
self-test failure 
Understanding the LED when testing the 
detector with GS960-TR tester 
The LED can have the following states during the test: 
•  Flickers: In test mode 
•  Flickers and blinks: In calibration mode 
•  Flashes 1.5 s: Confirms received signal 
•  Blinks slowly 1 time each 2.5 s after calibration: Set range 
setting to Zone 1 (4 to 9 m) 
•  Blinks slowly 2 times each 2.5 s after calibration: Set 
range setting to Zone 2 (2 to 4 m) 
•  Blinks slowly 3 times each 2.5 s after calibration: Set 
range setting to Zone 3 (1 to 2 m) 
Troubleshooting 
Detector does not respond: 
•  Check the supply voltage and polarity 
LED permanently on: 
•  Switch off the detector for a short period 
•  Check if LED is in latching mode (DIP 1 ON) 
LED permanently on with 2 dips per 3 s: 
•  Check supply voltage – it should be higher than 7 V 
No alarm: 
•  Check the INTRUSION and FAULT relay wiring 
•  Check the alarm loop wiring
