'98 Chimaera.
This lunchtime my alarm just started chirping every now and again. The suddenly all hell broke loose and it just went off. Used the 'plipper' to open the doors/turn off the alarm, but siren kept going. Got in the car, started the engine with the siren still wailing
I locked and unlocked the doors a few times, but still it carried on.
I decided to give the local TVR specialist a ring. The reply was most amusing:
"Have you been driving it in the rain?"
"Yes!"
"Ah! That'll be the problem. Best thing you can do is take the siren out, wrap it in a blanket and put it in a cupboard till the battery runs down."

That'll just shut it up - won't fix the problem - mine did the same needed a new siren unit - strangely enough most dealers have these in stock....... about £90.
had this problem with mine too, it would make some very interesting noises when the siren got wet, the best being when I pulled up outside a pub, armed the system and got a big wolf wistle!
seemed that water would fill up inside the siren and cause it to short out,
cured it by turning the siren so that the opening faced down and also put some silastic where the cable goes into the back of the siren,no problems since.

The other alternative although a bit late now, this happened to me and the reply from TVR I got was to unplug it at the front and then plug it back in again, this cured mine!!!
I tried this last night when it started again. Unfortunately it was dark and I didn't realise how fragile the connector is. When I found a torch the four little pins inside were splayed about all over the place.
Spent 10 minutes with the siren wailing in my ear with a small screwdriver bending the pins back to where they should be. Still didn't fix the problem.
Had to displace the Westie from the garage for the night and stuff the front of the car full of carpet so that the neighbours could get some sleep and hopefully let it dry out a bit.
It does seem better today, though.
If the siren's getting wet, do what I used to do in the good old days when men were men and alarms cost a mint 
1. Remove siren from car
2. Extract casing screws
3. Apply wife's hairdryer
4. Reassemble in reverse order
We were always getting cars in that had been bought at auction by Arfur Daley & Co. and steam cleaned or jet-washed by the teaboy. Alarm gets full of water (oe even just a bit of condensation if steam cleaned), PCB components short out, alarm goes potty. Dry it out and it's fine... till the next time!
