My Alarm is too "sensitive".

[Simplex]

Is there anyway way of "turning down" the sensitivity of the alarm system on my 1998 850 dti auto estate.

I've always locked the car with the remote fob. The car as always been sensitive to strong winds or hailstones, even thunder sets it off.

I've taken now to locking it with the key, but I'am not sure if this gives me any alarm settings.

Any advice would be welcome.

Thanks.

Is this a standard alarm system? I didn't realise they were adjustable.

hi mate

when i first got my 850 t5 i thought the alarm didn't work at all. then i noticed that the alarm horn under the bonnet was unplugged. maybe it was too sensitive for the previous owner.

maybe you could do this - immobiliser and dead locks will still work then

Hi robtd my friend, the best way to find out if all is well is to plug it in and try it! Best of luck.

it works fine mate

plugged in and singing away when required - just wondered if it may have been too sensitive for the previous owner

unplugging it may be a solution for this chap

if it is a1998 v70 the ultrasonic sensors in the B pillars were being replaced as they were too sensitive best way to tell is to take it to a volvo or independant repairer and get the alarm causes read.

Hey, I got one of these (V70 1998 AWD with the ultrasonic sensors). Was there a recall for them? Ours has gone off enough in the wee small a.m. that we now don't lock it at night using the alarm. People have reckoned it was probably bugs etc.

Cheers,

I have the same problem with my new C70 convertible. Volvo told me to remove any metal objects from the centre consol and armrest - made no difference. What is the answer to the problem raised by Simplex?
I now lock the car by following the instructions as though leaving dogs etc in the car, ie
Hold down the lock button inside the drivers door. The door locks then unlocks. Get out and lock with the remote. All is now set apart from the interior volumetric sensors. Works for me but need to know how to cure it.
Is it a microwave sensor? Had one on a renault which I could tune with a small screwdiver.
All ideas welcome.

Yes, was told the same by Volvo - do not leave any coins in the coin tray in centre console as it interferes with alarm (great design if true!!). Anyway, having not put any coins in for 18 months, the problem is sorted.

IMHO, that's crazy talk! the car is full of metal - the seat frames, heated seat/electric seat wiring/elemants/motors, the handbrake, gearbox, etc.

And the alarm is ultrasonic. It's not a metal detector. Like a bat's satnav, it is looking for a change in the ultrasonic reflections it receives to detect movement in the cabin. If any coins in the tray don't move, how could they set it off?

Of course, if that has solved your problem, maybe it's me who is crazy ;-)

Love to hear the opinion of an alarm expert here.
