Screw up of the day...

... lifting carpets to reveal many phone wires. The original owner liked to put in phone extensions...


<interlude> this is where thinking ahead would have helped.


... I don't need the phone extensions, I'll cut them out and... what's that noise? Yep, I cleverly cut through my burglar alarm feeds to the PIR sensors breaking the anti-tamper loop and triggering the alarm. The internal alarm could be cancelled but the outside alarm ran for 20 mins (legal limit).


I've resoldered the wires but now have supply/day/fault lights lit which means a blown fuse (according to the manual). Problem is that the panel has another anti-tamper alarm and the engineering code to bypass it appears to have been changed. This self inflicted hassle would be bad enough if I ever used the alarm but I've never set it.

Postscript (a logical conundrum). I cut two cables - on checking the sensors I discover that the hall and dining room sensors no longer work so they must be the cables I cut, right?

Apparently not - when I reconnected the wires it blew a fuse (marked as aux) but the dining room sensor started working.

I use an electrician who seems to know everything (and used to install Paragon alarms). After poking around a bit, he looks baffled and then says: "Any chance you swapped the cables?" I admitted there was every chance. It seems that, despite the logical evidence, one of the cables was for the outside siren, why 2 PIR sensors stopped by cutting 1 PIR cable and the siren cable remains a mystery (to me).

I/we also discovered that my ant-tamper alarms for the alarm case and the siren case don't function and that someone had reset the engineering code allowing you to bypass the tamper alarms anyway.

Just cut all the wires and bin it.

nah... £48 later (and I had to hold the ladder steady) it's working fine.

Every time there is the slightest disruption in power supply ( and for many other reasons it seems ) all the house alarms go off around us - and you know what, nobody takes a blind bit of notice - alarms are only any good if you are actually at home and it is your alarm, there are so many false alarms they are nothing but a nuisance these days - and any burglar worth their salt would just carry on as normal safe in the knowledge no neighbours will investigate the alarm going off for the nth time that month...
