Okay i just recently got a Viper 5002 installed with tilt, glass break, and back up battery sensor and a piezo siren. Well it worked great the first few days. well it recently went off randomly in at 3 oclock in the morning and just today at work it went off 5-7 times at work. After I disarm it it would beep 4 times then on the lcd display show sensor, and number 4, and alarm. So I don't know whats wrong with it. I just like to know what it is...i'm already set a date to go back to the installer and getting it fixed.
