Passive Infrared Detector (PIR) Issue
Hi folks. I have a 6000 Series PIR originally manufactured by GE security. The sensor is wired to a OMRON MK2P-S 8 pin relay. The relay controls an audio alarm. Everything worked fine for a while but now it no longer triggers the relay, despite the LED indicating it should. I can physically disconnect the COM connection and it will force the relay to trip and perform the desired alarm message. The voltage to the PIR is 13.5v (specifications indicate 10v-16v is the acceptable range). I have set the jumper for 2 and 3 pulse with no difference in behavior. Any troubleshooting ideas? Thanks in advance.
