PIR movement sensor not working - HOW TO FIX!

If your PIR movement sensor is not working on your burglar alarm system, then this video gives a guide of how to fix it.

Test your system by setting it, and then moving in front of the sensor to check it works. If it doesn't check the following;
- PIR sensor is faulty
- The sensor lens is covered (inside)
- Wires have come loose on the sensor
- The wire to the sensor is damaged

I thought you said "How to fix" 🤷 get a professional. Thanks for wasting my time.

On my sensor the LED will flash when moving but sometimes when there is no person in the room it stays on red instead of going off. Any idea how to fix?
