Removing an alarm box

[88V8]

I need to remove the alarm box/siren for maintenance of the wall to which its affixed.

Presumably if I use the engineer code, switch off the mains to the panel and remove the control panel battery I will be OK?
The battery in the box itself, if any, is fifteen years old and hopefully long dead.

If you have received no alarms, then the unit is probably dead. Burglar alarms these days quite cheap and you can install them yourself.

I replaced our Yale system control box with no problems and I prefer the DIY option to the 'professional' systems where they may take note of your layout and codes.

You need a loud sound inside the house. External alarms are often ignored.
