Here's how NPC works: If the alarm is triggered by the same sensor
or switch three times within a 60 minute period, your system inter-
prets this pattern of triggers as false alarms. After the third trigger,
your system ignores, or bypasses, that sensor or switch (along with
any other sensors or switches sharing the same zone) for 60
minutes. If the bypassed sensor is triggered again while it is
already being bypassed, the 60-minute bypass period will start
over. This ensures that a sensor that is continually being triggered
will remain bypassed.
The vehicle doors are protected differently. If your security system
is triggered by an open door for three, full 30-second cycles (one and
one half minutes), it will bypass the doors until the trigger ceases.
NOTE: Arming and disarming the security system does not reset NPC. The
only ways to reset a bypassed zone are for that zone not to be triggered
for 60 minutes or to turn the ignition key on. When testing your system,
it is important to remember that the False Alarm Prevention Circuitry can
cause zones to be bypassed and appear not to work properly. If five
chirps are heard when disarming the system, NPC was engaged. To clear
the memory, turn the ignition key on.
The microprocessor at the heart of your system has the ability to
constantly monitor all of the switches and sensors connected to it.
It can detect any faulty switches or sensors and prevent them from
disabling the entire system. It can also record and report any trig-
gers that occur when you are away from your vehicle.
