Best idea is to plug it into a diagnostic computer this will tell you the cause of the last few triggers i.e. door switches, interior sensor, bonnet switch, ignition on when alarmed or whatever. It'll cost you a few quid but its a darned sight easier than trial and error...

One thing you could try, is locking it with the key not the remote, this leaves the interior sensor deactivated (so you have perimetric alarm cover but not volumetric) this is so you can leave a dog in the car etc but it will also show up a dodgy volumetric sensor.

can someone tell me will the alarm module detect a drop in voltage eg short or earth fault somewhere

Are you sure that it was'nt a fly or the window open letting the wind rustle yeh "pine tree air freshener"?

As soon as I leave mine with the window slightley open the Alarm starts just as I'm walking away.

You can stop that by locking it with the key as described above :)

maybe not a be a fault last night 02.15 alarm went off got up looked out of window all looked ok reset back to sleep 10 mins later going again looked out this time reset and sat looking out of window to see a person pop up from the blind side after a loud bang from bedroom window and a lot of shouting thay were on their toes pity the dogs training pistol only fires blanks maybe some one wants it or something in it the moral is not to just look out of the window its a pity my 3 gsd dogs are out the back at least now its in the garden with an escort and fiesta jamned in front of it
