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.

Not on mine it won't.
There are many alarms around where doing that has zero effect on the bell
box.
