Diagnostics
The microprocessor at the heart of your system is constantly monitor-
ing 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, 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.
Note: Bypass notification will not occur when using Silent Mode or if chirps have been programmed OFF.
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 normal-
ly. 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.

Doors are covered by NPC differently: If the alarm is triggered by an
open door for three full cycles (one-and-one-half minutes), the doors
will be bypassed until the trigger ceases.
NOTE: Arming and disarming the system does not reset this function! The only ways to reset a bypassed zone
are for it to remain untriggered for 60 minutes, or to turn on the ignition. If testing your system, it is impor-
tant to remember that the NPC programming can cause zones to be bypassed and seem to stop working. If five
chirps are heard when disarming, NPC has been engaged. If you wish to clear the NPC memory, turn the igni-
tion on.
