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

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 ig-
nores, or bypasses, that sensor or switch (along with any other sensors
or switch es sharing the same zone) for 60 minutes.

nores, or bypasses, that sensor or switch (along with any other sensors

If the bypassed sensor tries to trigger the security system while it is being
by passed, the 60-minute bypass period will start over. This ensures that
a sensor that is con tin u ally being triggered will remain bypassed.
The vehicle doors are protected by NPC differently. If your security
system is triggered by an open door for three full cycles, the system will
bypass the doors until the trigger ceases.

Note: Arming and disarming the system does not reset this function. The
only way to reset a bypassed zone is to not have it trigger for 60 min-
utes, or to turn on the ignition. If testing your system, remember that the
NPC programming can cause zones to be bypassed and appear to
stop working. If fve chirps are heard when disarming, NPC has been
engaged. If you wish to clear the NPC memory, turn the ignition on.
