Honeywell Accenta G3 tamper alarm

Re: Honeywell Accenta G3 tamper alarm

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?

Yes, that means the backup battery in the main unit is dead. I had the same problem a few years ago. What I found is that duct tape over the siren will quiet it down enough for it to not irritate the neighbors while you replace the battery in the main system.

Re: Honeywell Accenta G3 tamper alarm

Tamper fault puts the unit into lockout and the keypad acts dead until that fault is cleared, only by entering User Code then Engineer Code. If that has been changed from default 9999 then only choice is phone the alarm company that knows it, or blow out the entire program back to factory defaults.

I'd be tempted to disconnect the siren, yes it's another tamper fault event but at least then you can check/replace the battery.

If the alarm panel sounds an alarm while power is off, there must be a battery somewhere in order to sound the alarm.

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.
