When changing the 500mA aux fuse on my panel I disconnected the mains power and battery but when I pull the fuse the bell box still goes off on its battery.

 

How do I stop the bell box going off when working on this panel as I have particularly grumpy neighbours.

alarms have self activating bells,

 

when the power is removed from the unit, it sounds (powered by its own battery)

 

in most case if you don't want it to sound you get the ladder out & disconnect the battery...

Yup that’s what I assumed!!!

 

Just hate doing that as the sounder hammers my ears when you lift the bell box cover. You pros must use some serious ear defenders ???

It shouldnt go off if the battery in the panel is ok, and why do you need to replace the aux fuse?

Cos it blew when I accidentally shorted the + and - on a PIR ?

Okay most people dont know why the fuse blew, blown fuse is a symptom of a problem in many cases

Just power the bell/siren direct off the battery while you work on the panel.

This will hold the SAB silent.

There will be a short blip (duration of however long it take you to remake the connection) I normally prewire a common neg and only disconnect and reconnect the positive. Use a lead with a spade terminal one end and an insulated crock clip the other (or crocks both ends)
