Replaced a failed PIR today and now have faults on all zones.
Prior to me meddling, each pir detected movement and illuminated the led with the exception of the failed one. Now none are showing leds and each zone is reporting a failure at the control panel.
They still trigger the tamper alarm if I take the covers off though?
I've reset the alarm at the control panel and set each zone type to 'guard' but that hasn't changed anything. Have I goose'd all the pir sensors somehow or is there something else I need to reset somewhere?
Cant really help you but I would refit the old PIR and get the system back working again.
Then remove a working PIR and replace with the new one. If all ok then at least you know the new one is fine. If not then its faulty.
I did that initially. Old sensor from kitchen replaced the broken one and the new one fitted in the kitchen.
Looks like I'll phone an alarm chap tomorrow.
Can you see a red light on the pir itself when you trigger it? Sounds like you might have shorted out the power supply to the pir and popped the fuse (if it has one!!).
No, no red lights on any of the pir's so I'm guessing I could have shorted something. Will pop the front off the alarm box in the morning and try to check the fuses.
Dunno about house alarms, but some fire alarm sensors have little numbered switches (DIP switch) inside that need setting
You've blown a fuse in the control panel, usually a 1 amp quick blow. Sometimes theres spares in the panel.
Thanks stof...in the control panel/key pad bit the main alarm box?
In the main control panel.
Thanks to stof, it was indeed to the Aux & Speaker fuse that had blown.
Unfortunately, now the sensors are working again they trigger the alarm even when it's not set 🙂 so I've put the blown fuse back in again until the weekend when I have some time and daylight to sort it out.
