How to disable a burglar alarm

[HappyHippyDad]

Inside the bell box will be a series of pins with a jumper plug, the pins will be denoted, one combination of pins will disable the bell box siren with the jumper plug.

Factory set engineers code is usually 0000 or 9999, some unusual ones are 1234.

Or as most scrotes do just fill the bell box with builders foam.

Bloody ell.. I started reading that and thought I was in mission impossible!

Definitely let us know how this one goes Pirate.
It could be quite funny
As above, take ear defenders up the ladder with you, as it is going to be horribly loud right next to your head.

If it's been there a long time, there's a good chance the bell box battery is approaching uselessness.

Find panel (not just keypad, the main box)
Remove mains power to panel.
Open panel (alarm will go off)
Remove spade terminals from battery from panel.
Panel speaker and any extension speakers will stop making noise.
The only thing left sounding will be be bell box if the battery is any good.

After 15 minutes max the bell box should stop.
The battery will discharge.
Game over.

OK guys, thanks to all of you for your advice! The general consensus is wear ear defenders, have cutters to hand, get the bell box open and hope for the best!
I will certainly report back. Fortunately, the bell box, which is in the communal stairwell, is only about 7' above floor level, so hopefully I won't fall far off the ladder! It'll be a while before I do this job due to a recent op which prohibits ladder work for a week or so, but watch this space.

Your post reminded me of this...

Tim has nailed the procedure, also if the battery is not completely dead you could connect the bell cable to it to keep the bell silent until you've got to it.

I've disconnected/upgraded loads over the years, you'll be surprised at how little people actually care about a ringing bell box, as long as its not middle of the night.

also if the battery is not completely dead

...then connecting a wind-up megger to the bell supply can produce useful undocumented results.

Oddly enough, I do actually have a wind-up megger! It sits on my curiosity shelf beside my AVO which, sadly, I can't get to work despite buying an expensive new battery for it...I'd like to get it working, but that's for another thread.
