PIR Issue

dashoonage

Lads/ladies im at my wits end here. I have 3 flood lights and 2 PIR's. There was a power cut last year and they were stuck on after it. No matter what i did they wouldnt go off. So i just replaced the PIR's there with new ones of the same make


Here is the behavior

-Turn on power lights come on
-Lights go off at required time,say 1 minute
- trigger PIR lights come on
-Lights dont go off at all

now here is where it gets weird. If i trigger the PIR while the lights are stuck on, then the lights will go off after 1 minute

No wiring as changed in 10 years! and they worked fine until the power cut last year.

open to any and all suggestions here

Either pir switches on 3 lights?take off one of the pir heads

Did u rewire the bases as well or just the tops

Try them one at a time ,you prob mixed up a live in/out unless there's a faulty pir

Yup either pir switches them all on. Didn't have to rewire bases just replaced the heads, same type of pirs so just left the bases.

Will start eliminating the pirs again on saturday. All brand new units though

Isolate the power supply from the consumer unit and turn it back on after 10 seconds. This will reset the lamps and take them out of "Permanently on" mode.
