This house has a Honeywell Accenta G3 alarm system. If the main unit loses power for any reason, the external siren sounds - even if the alarm is not even armed! Entering the code to disarm it is not an option as the keypads are completely dead when the power is out.
I presume this means the backup battery inside the box has failed, but I can't get in there and replace it without also setting off a tamper alarm! Is there any way to disable the tamper alarm so that electrical work can be carried out with the power off? Or a way to replace the backup battery without setting off the alarm?
