Diagnostics
The microprocessor at the heart of your system is constantly mon-
itoring all of the switches and sensors connected to it. It detects
any faulty switches and sensors and prevents them from disabling
the entire system. The microprocessor will also record and report
any triggers that occurred during your absence.
If the system is armed while an input is active (door open, sensor
triggering, etc.) the unit will chirp once when arming and then
again a few seconds later. This is called Bypass Notification. The
system will ignore the active input until it ceases. Three seconds
later it will monitor that input normally. For example, if your car
has interior light exit delay, and you arm the system before the
interior light goes out, you may receive Bypass Notification. Once
the light goes out, however, the doors are monitored normally.
NOTE: Bypass notification will not occur when using Silent Mode
™
or if
chirps have been programmed OFF.
Extra disarm chirps indicate Tamper Alert. If four chirps are heard
when disarming, the system was triggered in your absence. If five
chirps are heard, a zone was triggered so many times that Nuisance
Prevention Circuitry
™
has bypassed that zone. In either case, the
status LED will indicate which zone was involved (see Table of
