Hi all

Just received my alarm parts ready for upgrade.
One question that came to mind relates to the bell box.
If the backup battery is removed/disconnected from the bell, will the bell
still work off the panel power?
Is the backup battery only used in the event of power being cut between the
panel and the bell?

Yes, provided you have connections to + (aka + holdoff), - (aka -
holdoff) and trigger (aka just about anything). Wouldn't do it myself
for extended operation though.
