does the alarm activate i.e external siren or does it bleep twice and stop?

I think what the guys above are trying to say is that there could be something seriously wrong with your electrics.One of our engineers went out to a system today and found that when the landing light was on he was getting 150v between neutral and earth( this voltage under normal circumstances should be 0v ideally) so the actual control panel lid was becoming live. This was not a fault on the alarm and our engineer isolated totally from the spur, downpowered the system and strongly advised the customer to get an electrician in.

And thats fine (and thanks!) but Im not convinced that its not a problem with the alarm (yet)If I isolate the alarm from the mains and then try my "test" will that tell me anything that I dont already know?The alarm will be running off the battery so it should tell me if the problem is with the supply or the alarm wires, right?

the buzzer sounds (45 secs to disarm) if I let it go it will fully activate (internal and external bells sound)

Sorry, but wrong. Unless you know EXACTLY where all the alarm and mains cables run in your house, that they are well-separated and that there aren't any faults or shorts anywhere in either or between them.

nope not unless you have a DP switch - call out an engineer ( they didnt know they had it dialling out ? - impossible )

well I know where they all are but I cant say that they are all short free, but I cant imagine that something has changed since yesterday.... such a weird (annoying!)manifesation

things can change since 10 minutes ago - it could be dangerous , get it checked by a competant engineer ( tonight if possible ) it sounds like your on a monitored / rental thing to me ( you in manchester ? ) - if you are just call em in

they didnt realise that they had it set to dial out when the alarm was set and activated...very handy for me every morning/evening

nah, its just a dialler that rings a couple of numbers during an activation....

Gonna have to bite the bullet and call them tomorrow

cool its the right choice , if they give the alarm a clean bill - ask em about induced ac then maybe youll need a sparky too ?

post back if you need advice about what they say

Think about it - carefully!

1. Your alarm shouldn't take any notice of changes in your normal electrical circuits, including normal power cuts of several hours. EVER.

2. Somtimes they do, for extreme events like thunderstorms. You can get filters/protection for this.

3. IF your alarm triggers for ANY tiny operation of ANY mains switch then either:

a. The alarm has a serious fault which is incredibly sensitive to tiny mains fluctuations, OR

b. You have a serious, possibly lethal, fault in your mains supply.

If a. it's useless as an alarm; you need an engineer to fix it. He would quickly tell you if it was option b.

If b. You need an electrician URGENTLY. You may sit in the bath and kill yourself (or wife, or kids..)

If it was me I wouldn't take either risk, but especially not the second one!
