I am new to this forum and new to owning an Omega; I bought a 2001 2.2 auto CD saloon a month ago and very happy I am overall......
However, one problem I would appreciate some advice on. My alarm seems to be hyper-sensitive and goes off for no apparent reason. Is there any way to lock the car without activating the alarm? Or can the alarm be de-sensitised? Other than by nobbling the horn, can the audible alarm be turned off completely?
Despite living in south London, peace for myself and others at night is currently a higher priority than anti-theft....!
Thanks,
Alan

3 posibilities on order of preference .. :)
1) Power sounder batteries are dying/dead .. :( Do you ever hear 4 little chirps when starting/stopping engine ?? Either way ... disconnect the powersounder (10 minute job) and see if that fixes it.

2) Bonnet switch misaligned ... Especially in the present weather, as the bonnet expands/contracts with heat/sunlight it can trigger the bonnet switch if it has been dislodged.. a common-ish thing given where it is and the propensity for it to catch on sleeves whilst working on the engine !!!
3) Something "live" inside the car that starts to fly around once stationary ... had this with a large moth one time ... turn off the motion sensor and see if this sorts it .. :)

PS .. BTW .. "Hello" and Welcome :)

May be its the bonnet switch they do play up and very often the hot weather aggravates this problem , the bonnet expands slightly and this activates the switch and the alarm goes off . To check if it is the switch you can do a couple of things either unplug the switch or use a cable tie to hold the switch plunger down . If this solves the problem you can either leave it like this or locate the area on the bonnet the switch makes contact and put something in there to make sure the switch is depressed properly .. The plastic cap from a milk bottle fits :y

Thanks for the advice. I assume that there is no way to lock the car without activating the alarm. Is that right? I had an old Carlton where I could do just that.

No but I shall listen out for that. Please excuse my ignorance, but what does the power sounder do? Will disconnecting it stop the audible alarm?

I shall have a look at that.

This I am now doing and await results.....

I would bet on the bonnet switch to be honest :y
The power sounder is a battery backed up alarm ie if someone disconnects the main car battery the alarm can still sound and gives protection :y

you shouldb e able to lock without alarming, by using just the door pins, obviously you have to do the drivers via a different door, and be carful not to lock your keys in.
My money is on the bonnet switch :y very easy to try as well
-
I just thought of something else it may be worth checking that the door switches are ok including the boot switch , My alarm was going off the other week and I found I had not shut the boot down properly :-[

Miggy has 2 audible alarms .... 1) the "normal" horn type that goes off whenever an occurance is detected. 2) the power sounder siren which goes off it the battery is disconnected (This is to preent a scrote simply cutting the battery feed and then nicking the car) and nhas internal batteries to do this.
The powersounder is permanently connected to the car battery and should maintain its charge that way.
The problem seems to be that when the powersounder batteries get old a couple of things can happen ....
1) - most common : They don't charge up and so tell the alarm ECU there is a problem .. so the alarm goes off
2) - rare but has happened : They leak causing shorts on the electronic board that causes false alarms or even fire
Disconnecting the PS does not stop the normal alarm working .. you just lose the disconnect protection. A new PS is around £60 from VX but cheaper from a breaker, however it may have the same problems as your own. A forum member is looking into offering a refurb service once he gets all the logistics finally sorted.
