Hi

I've found the type of battery I need in the main power box of this alarm system but is there another battery in the outside 'bell/light' box & if so what type is this?

That depends on the sounder fitted, only one way to find out though, get your ladders out and take a look.

The details will be written on the battery/ s.a.b,.

Put the panel in engineering before you remove the sounder's cover, stop you getting tamper alarm.

Or simply tell us the make/ model of you sounder, and we can tell you what should be fitted.
