It would be wrong of anyone to post information of how it would be possible to trigger anyones alarm but it is possible to do. Ive never heard of it happening but that doesnt mean it wouldnt or couldnt.

Arfurs point though is a very valid one, just because you can replace the stand-by battery doesnt mean you can resolve the problem. Without a proper check the system could still be carrying a fault and his suggestion to get it checked by a proffesional is good advice. I suspect thats why you came here, to seek good advice!

Thanks

Could well be true, it's easily detected with the right (simple) equipment.

I had a few false alarms, did tests, fitted a filter after asking for advice here. All OK since.
