Matrix Alarm Arming Diagnosis needed

I have a matrix alarm with a two way remote installed in my truck. I also have the glass break sensor installed on zone 4 (506t). I never really noticed before, but when i arm the alarm, i get a secondary chirp, which i assume is bypass notification. HOWEVER, i get no indication as to WHAT zone has a problem from my LCD remote. The only thing that is wierd is that immediately after arming, the LED in the truck flashes 4 times, pauses, flashes 4 times, pauses. It does this repeatedly for 60 seconds, then the light just flashes normally. What does this mean? My audio sensor is not supposed to be active until 3 seconds after arming. Im at a loss and need help. No other lights or anything are on when i arm it either. Ideas?

does your car have a delayed domelight

yes, HOWEVER, this is not the issue. Reason is, if i immediately get out of the truck, and arm, i get the bypass notification and the LCD on teh remote tells me that the door trigger is bypassed. So, this is why i didnt notice the symptom of my first post. If i get out, and wait for all teh lights to go out, and then arm it, i still get teh bypass chirp, but no indication on my LCD remote about what zone. The only info i have is that the LED in teh car flasshes like i noted. It also does this for 60 seconds. Nothing in the manual says anything about 60 seconds.

OK, if i unplug the glass break sensor from the 'brain' i no longer get this problem. So, does this mean there is something wrong with the glass break sensor or what?

did you isolate the sensor when it was installed??Kevin Gerry

What do you mean 'isolate'? I dont know if it matters, but i get the same problem whether i arm teh alarm normally or in 'silent' mode. It never gives me a response on my remote. The alarm just beeps a second time and the light flashes four times for 60 seconds.

Anyone have any idea why the glass sensor would trip bypass notification?
