some older (over 10 years) panels were very sensitive to electrical
interference and radio transmissions (taxi, police, amateur). If it is
that sort of age or older I would change panels (Texicom recommended).
And the panel back-up battery.

My in laws have gone on holiday and I am doing some decorating and looking
after the house. The problem is the burglar alarm goes off every day. I
set the alarm at approx 3PM and I get a call from their neighbour at 8 to
8-30 PM saying "the alarm is going off". The electricity has never been
switched off by me for decorating purposes. When I look at the event log,
it is always a different zone so that discounts a spider etc crawling over a
passive. Two of the activations have been 1 x door contacts (not surface
type) and 1 x panic button! I have now left the alarm off to save the
neighbours any more grief. Why would it go off after 5 hours or so? Any
ideas before I call an engineer?
