Hi I have initially searched this forum but could not find an answer.
Our builders removed the bell from our burglar alarm to carry out some work. We put the bell back and the unit seemed fine. There was no tamper light. However none of the PIR sensors work anymore. There are no lights on any of them. I've just done a walk test and seven of the eight zones are were lit up red. However there are still no lights on any of the PIR's. Anyone have any ideas? The manual is silent on this. The alarm is old, not sure how old, definitely more than 5 years.
Thanks
