Ok thanks for the advice ?

Sorry to revive a very old thread, but if the battery is flat is there no way of reviving it? Only option is to buy a new one?

I'm a little confused trying to figure out how the G3 control panel works... So, you have a spring which is designed to detect when the control panel has been opened and trigger the alarm. However, within the control panel you also have a battery which, if I've understood correctly, powers the entire system, so this can just be yanked out, rendering the tamper alarm fairly useless.
