Diagnostics
The microprocessor at the heart of your system is constantly moni-
toring the switches and sensors connected to it. It detects any faulty
switches and sensors and prevents them from disabling the entire
system. The microprocessor also records and reports any triggers
that occurred during your absence.
Arming diagnostics
If the system is armed with an input active (door open, sensor trig -
gering, etc.) 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until the input is no longer active. 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 t amper alert. If four chirps are heard
when disarming, the system was triggered in your absence. If five
chirp s are heard, a zone was triggered so many times that NPC has
bypassed that zone. In either case, the st atus LED will indicate which
zone was involved (see Table of Zones section). T he system will
ret ain this information in it s 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.
