Diagnostics

The microprocessor at the heart of your system is constantly monitor-

ing 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 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 trigger-

ing, 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the input is no longer active.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 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 NPC has bypassed that

zone. In either case, the status LED will indicate which zone was

involved (see Table of Zones section). The system will retain this infor-

mation in its memory, and chirp four or five times each time it is dis-

armed, until the next time the ignition key is turned on.

NNoottee::

Bypass notification will not occur if chirps have been

programmed OFF.
