What happens to a burglar alarm (just a stand-alone one, not centrally
monitored) when mains power is off for days? I know that the internal
battery will obviously discharge but does it actually trigger the sounder
at any point, or does it just die quietly?

We're going away for two weeks, during which time the house is being
rewired and I don't want the neighbours being disturbed by a shrieking
alarm.

TIA


Once power is disconnected, the alarm will activate. Your external bell box
will most likely have a battery back up. The external box will sound until
either battery goes flat, or power is restored and alarm reset. Best option
is to enter the engineer code into the alarm (if you know it). This will
stop the alarm sounding when power is disconnected. Alternatively,
disconnect battery backup from both alarm panel and external bell box (not
sure, but this may wipe the alarms internal settings or it may have a small
watch type battery to retain settings).

What alarm is it?
