guys, after 2 days owning my 98 xantia V6 a horrible thing has happened...

in a very residential neighbourhood, my alarm is freely going off

the hazard lights are not flashing. I have disconnected the battery tonight, and all is quiet.. but my confiedence is ruined with reference to alarms.. I will be awake any nights the battery is connected, wondering if it will go off...

how can I quickly remove the siren from the system, either permanently or in an emergency?

what is likely to be causing this misguided activation?

thanks
John

First things first.... lock your car with the key not the remote.... this means that the alarm is not armed.

ok...

thankyou

what does the button on the dash do, looks like - soundwaves are banned - ?

So you can lock the dog in the car and he won't set the alarm off ... basically!

but leave a little gap in the window and some water for the dog, and remember dogs die in hot cars. So only do it in the winter.

Try a search on ultrasonic sensors. These are reputed to set off the alarm by itself ...
Some Xantia models have a small toggle switch to disrupt these sensors.

In my Xantia Handbook mode...

"Switching off the siren.

To neutralise the siren so that it will not sound, open the bonnet, lift the cap off the lock situated below the air inlet grille, introduce and turn the vehicle key. The detection functions will still operate, but the siren will not operate.

Do not forget to neutralise the siren should the vehicle battery be disconnected.

If your vehicle is fitted with deadlocks, the alarm is armed by deadlocking the vehicle with the remote control."

Got that!?

Mine has the same trouble, but I'm pretty sure it's the ultrasonics as if you disarm them the siren stays quiet. A bit of a pain to change them so I've left it until I can figure out a way to find out is it's the transmitter or receiver that's duff to save having to change them both.

Alarms are a pain in the back side, mine goes off randomly from time to time to, 4 times in 2 months for what i feel no reason.

I guess it could be down to... wait for it... "anything"!

2 things..

when mine went off last night, it didnt activate the flashers, and couldnt be turned off with the button on key (or opening the car or starting it up)

And, if i try to disable the ultrasonic sensors, according to my manual, and tests, it only happens once. i.e i have to disable them every time i leave the car

hmmm

Hi all.
I do not know if I have a cure for your alarm going off.
Mine randomly did the same till I replaced the main car battery due to low volts off charge, even though its green indicator said it was O.K
That was two months ago and so far so good.

WARNING:

If it only seems to be when outside the house that the alarm goes off randomly, it may not be false alarms, but someone who is after your car.

They used to do this ages ago - make the alarms go off for a while until the owner gets fedup and disables the alarm - then they'll have either the contents or the car away !

On the other hand, my dad's Xantia used to go off every now and again - we found that by setting the vents to face level, and turning off the face-level vents, it solved the problem !
