your system ignores, or bypasses, that sensor or switch (along with
any other sensors or switches sharing the same zone) for 60 min-
utes. 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.
NOTE: Arming and disarming the system does not reset the Nuisance Pre-
vention Circuitry. 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 this circuitry can
cause zones to be bypassed and appear to not work. If five chirps are heard
when disarming the system, the NPC was engaged. To clear the memory,
turn the ignition key on.
Diagnostics
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 while you are away from your vehicle.
If the security system is armed at the same time that an input is
active (door opening, sensor triggering, etc.), you will hear one chirp
to indicate arming and a second chirp to indicate Bypass Notifica-
tion. A Bypass Notification chirp means that the system ignores the
