Nuisance prevention circuitry
Your system has Directed’s Nuisance Prevention Circuitry (NPC). It
prevents annoying repetitive trigger sequences due to faulty door pin
switch es or en vi ron men tal con di tions such as thunder, jack ham mers,
or airport noise.

For example, if the alarm triggers three times within a 60- minute
period and each time the same sensor or switch triggers the alarm,
NPC will interpret those triggers as false alarms. After the third trigger,
NPC ignores, or by pass es that sensor or switch (along with any other
sensors or switches sharing the same zone) for 60- minutes.
If the bypassed sensor tries to trigger the system while it is being by-
passed, the 60 - minute bypass period starts over. This ensures that a
sensor that continually triggers will remain bypassed.
Doors are covered by NPC differently - if the alarm is triggered by
an open door for three full cycles, the doors are bypassed until the
trigger ceases.

Arming and disarming the system does not reset this function. In order
to reset a bypassed zone, the same zone must not trigger for 60
minutes, or when ignition is turned on. If testing your system, it is
important to remember that the NPC programming can cause zones
to be bypassed and appear to stop working. If five chirps are heard
when disarming, NPC has been engaged. If you wish to clear the
NPC memory, turn the ignition key on.
