diagnostics
The microprocessor at the heart of your system is constantly monitoring
all of the switches and sensors connected to it. It detects any faulty
switches and sensors and prevents them from disabling the entire sys-
tem. The microprocessor will also record and report any triggers that
occurred during your absence.
arming diagnostics
If the system is armed with an input active (door open or ignition) the
unit will chirp once when arming and then one more time a few seconds
later. This is called bypass notification.
The system will ignore the input that was active when it was armed until
it goes away. 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 get bypass notification. Once
the light goes out, however, the doors are monitored normally.
disarming diagnostics
Extra disarm chirps are the 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 false alarm prevention
circuitry has bypassed that zone. In either case, the status LED will indi-
cate which zone was involved (see Table of Zones section). The system
will retain this information in its memory, and chirp four or five times
each time it is disarmed, until the next time the ignition key is turned on.
nnoottee::
Bypass notification will not occur if chirps have been
programmed OFF.
