Hi,
Hopefully the people on this wonderful site can help me again.
When we bought our bungalow in 2005 one of the 1st things we did was get a burglar alarm installed. Unfortunately the installer has retired.
PIRs were installed in each room except where internal.
Over the years we have had 'false' alarms from our dining room during the night.
They rarely happen when we are at home, but mostly in the early hours of the morning when we are away.
It has happened on the last 2 occasions and we really can't expect our neighbour to switch off the alarm any more. (Age and health are against her)
Our 1st countermeasure will be to omit that zone in future but obviously we'd like a permanent fix.
Thinking it may be a spider we spray all our rooms with insect killer before we go away. This obviously doesn't work.
The PIR faces diagonally across the room but there is a large South facing window opposite. Our neighbour has a security light that unfortunately shines into the room (protected by vertical blinds only). However my understanding is that this is unlikely to be the cause.
I am struggling with the fact that the problem is intermittent and that it mainly occurs when we are away. (Or could that just be coincidence?)
Because the room is South facing with a large window could it be that temperature changes means we have a faulty PIR? If so, is replacement a DIY job and is there a preferred PIR type or make?
Failing that, if I ask another installer to look at the alarm system will they be able to find an intermittent fault?
Thank you
