Hello,
I installed the pet immune motion detector PSG9984P about three months ago and it has been working fine. Yesterday it started blinking yellow and red every 30 seconds. The installation instructions note that this is a “self test failure” but do not explain what that means or how to fix.
I tried tampering the device and uninstalling / reinstalling from my panel but I’m still seeing the same behavior. The panel reports the sensor as idle so not having communication issues.
How should I troubleshoot further?
