Thanks everyone. So I googled and found on here how to access the PM360 using the app and connecting to wifi. The errors are below (we have one siren, a front door contact and two motion sensors - hall and living room)
Front door - CNTCT Vanish (Guessing related to replacing the battery)
Living Room - motion sensor missing
Hall - motion sensor missing
Siren - tamper alarm (I removed the cover yesterday and out it back on)
KeyPad - tamper alarm
Siren missing
GSM Net Fail
GPRS Net Fail
im no expert but that’s a lot of things with alarms or missing so I’m making the assumption it’s going in the bin. Few people mentioned above but how do I remove this? Whenever weve unplugged the PM360 before eventually the siren goes off. As suggested above do I just take the siren off of the wall and smash it up with a hammer or sledgehammer? Is there a more elegant way or is it just brute force?
