Viper alarm triggering

[A L 3 X]

I've got a viper alarm with the ultrasonic sensors at the top of the a-pillar, and it seems about ten mins after i get home at night and arm the alarm, it will sound...and keep sounding about 3 times when i go out and disarm and re-arm....but then after fiddling with the sensors or something it will stop....until the next night at home...when i unlock it and check the LED its telling me its the ultrasonics that are triggered.

I've positioned them so they aim at the top centre of the rear windscreen, and on the alarm theres a setting to adjust the sensitivity of the ultrasonics with the remote, defailt was 10 out of 20, i have turned them down to 8 out of 20.

Can anyone diagnose the problem or suggest if I should turn the sensors down a bit more? How much isturning them down too much?

Thanks

You can put the alarm into service mode, sit in the back seats and adjust the sensors so they go off when you move in the back.

You will need to find the service manual for you model.

Thinking about it my viper did this in the winter, think its the hot air in the car cooling causin movement in the air and triggering it.
