Avantguard 5 Acting Strange

Installed my Clifford AG5 a few months ago and everything worked fine until a few days ago.
This occurs only once in a whyle.

When I press the button to lock the car the system will chirip 3 times and the alarm will blow instantly.
I disarm , check all the doors , the hood , baggage room, I arm again ... the siren blows.
I put system in valet mode and let it be until next time I drive. Then I take it out of valet and arm when I park... everything ok.

I go to sleep and at 5 AM the system blows ... I wake up and I go down to the car to stop the GSM pager that calls my mobile every time the alarm blows.
I arm the system everything ok.
At 6:05 AM phone rings again , alarm started... I go down again to stop the GSM module. Disdarm the car , arm it again ... everything ok.
At 6:30 alarm again.... go down .. stop GSM module , put the car in Valet mode and go back to sleep until 7:30.

I drive to work , park the car and when I want to arm the system siren starts wining right away...

I take my brand new notebook and want to check the system event trough the Clifford Wizzard but I just realyze my notebook has no serial.

Anybody any ideea what can be wrong ? I will check it in the weekend with another notebook but until then I might discover what is wrong.

By the way , I have installed the 516L Voice module and the module does not report any door or baggage room open when I arm the system...

Any ideea ?

What zone is being indicated by the alarm? If must be telling you something . . .
