prets this pattern of triggers as false alarms. After the third trig-
ger, the NPC
™
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 by NPC
™
. If your secu-
rity system is triggered by an open door for three, full 30-second
cycles (one and one half minutes), the system will bypass the
doors until the trigger ceases.
NNOOTTEE
: Arming and disarming the system does not reset the 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 NPC™ can cause zones to be bypassed and
appear to not work. If five chirps are heard when disarming the system,
NPC™ has been engaged. To clear the NPC™ memory, simply turn the igni-
tion 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.
