Car Alarms: alarm going off, shock sensor, gm vehicles

Question
I just installed a Audiovox Prestige APS-786T in my 2005 Buik LeSabre, and every thing seemed fine, until I activated the remote start in the morning when I woke up. After about a minute of running the alarm starts going off. I've tried to get it to repeate the problem in the afternoon when I have time to troubleshoot it, but the alarm doesn't go off. I've adjusted the shock sensor to max. to try and eleiminate it also. The only thing I'm wondering about is if the auto ride height adjusts in the A.M.  and if that could be my problem?

Answer
You mean the Audiovox alarm is going off, not the factory, correct?

The shock sensor input on the Audiovox should be automatically disabled when remote starting.  To verify that it is not the shock sensor, just disconnect the molex plug that is going to the brain of the alarm from the shock sensor and try it again.

How did you interface the door trigger in this vehicle?  My sheet is saying that you must diode isolate all of the doors in order to prevent falsing.  More than likely the brain of the vehicle is doing a self check after being shut off for so long and this is causing your falsing, if the door triggers were not isolated.

Let us know.
