House Alarm - help please

smity · Jan 11, 2009

I havent long lived in my current house and my upstair's bulb blew this morning and tripped the mcd for the upstairs lights which set my alarm off

So i inspected further to find the alarm is wired into the upstairs lights mcb shouldn't this be on its own mcb as there is room for one?

If so what amp mcb do i need?

Regards

Hey.

Yeah if theres room for it then put a 6A MCB in to cover the alarm circuit. It would be good to make sure that it only feeds the alarm and nothing else though.

Cheers.

As the alarm sounded when the breaker tripped, doesnt that mean he could do with a service on his panel, with the sounders sounding?. New battery possibly needed...

Thanks mate thought it was odd to have it wired in to the light circuit.

I would agree sounds like the battery is shot

When you say it went off, did the bell box ring or was it just the loss of AC power warning??

what happened is when it tripped the outside bell box went off then when i pushed the mcb up it sounded the siren inside the house and i had to enter the code to shut it up.

That sounds like a new battery is actually required. Basically when the power to your panel is cutthe 12v battery inside the panel then takes over the panel as a backup, but if the battery is dead the bellbox then self activates its internal backup battery, and sounds the alarms. As the internal sounders kicked in once power was restored, this was because of the bellbox already in alarm state, this then triggering the internal sounder..
