Decided to disconnect my battery today to save killing it over the winter, but my problem is that as soon as I disconnect the negative terminal it triggers the alarm if activated.
I am not bothered about the alarm being on, just want to keep the doors locked.
Anyway around this? Does the alarm have a back up battery and is it a case of waiting for it to drain itself?

Why not pull the main fuse? I do this all the time and just pop it back in everytime I take it out.
Do you set the alarm before you pull it? I need to as I want to keep the doors locked. Had a look at pulling the wiring from the back of the alarm and after a brief look decided that it was going to a real pain to get to it. So just diconnected the battery and let it run, it just switched off after a while, not sure my neighbours were happy though
I had a problem once with a Lotus Exige that had been left unused over the Winter, where the car security system wouldn't allow the car to be unlocked when the battery was flat. I couldn't get at the battery to charge it. The car handbook told you how to get round this situation, but it was locked in the car! I found out from the dealer that there were a couple of terminals connected directly to the battery hidden under one of the panels in front of the windscreen that could be unscrewed. After charging the battery via these terminals, everything was back to normal and the battery operated with no problems from then on.
Since that incident I have always used an intelligent charger, that you can leave connected all the time, on any car I do not intend to drive over the Winter. If you got one of those, you wouldn't have to disconnect anything and your car would still be protected by the alarm system.

Not option for me, where I park has no sockets and an extension cable would not be feasible. So only left with disconnecting it to prevent drain.

i am in a similar situation with no power supply in the garage. Have you solved the problem disconnecting the battery / alarm ..
It has been mentioned on here to pull the main fuse but i think then the car remains open ? let us know if you got the answer

All I did Stefano was to activate the alarm, stuff rags in front of the siren and disconnected the battery. After about 5 minutes my alarm switched off, didn't sound like it had run out of battery. Doors are still locked and hasn't gone off since.
Haven't bothered looking into the fuse, as I fitted a switch that cut off the negative supply to the battery. But this was a real pain to fit as there is not much room down there.

good thread this - how do you disconnect the siren. If you do it with the alarm off as posted earlier does everything else work but it doesn't make a noise if set off. I go away and my alarm is unpredictable so this would be a good solution.
If the alarm is off when you disconnect the battrey it doesn't go off, at least mine didn't.I didn't bother with it in the end. Whoever wired my alarm in made sure it wouldn't be disconnected easily, so i gave up on that idea. Plus i would have thought the alarm controled the central locking, another reason i have up on that solution. Maybe someone else on here can answer that?

am i right in saying if the battery does drain the alarm will go off . Hence ,that's why you disconnected the battery set the alarm off and let the alarm siren come to a stop and the car still remains locked ?
How do u get the alarm to go off if the car is locked , open the rear clam or ?

does anyone have a pic of where the main fuse is , before i pull something else out .!

Don't have any pics, but it's on the driver's side under the rear clam, kind of a plug housing a big fuse. The plug pulls apart. If you can't find it, drop me a note and I'll talk you through it over the weekend.cheers
