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 switches sharing the same zone) for 60 minutes.
If the bypassed sensor tries to trigger the security system while it is 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 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.
NPC requires that you change the way you test the system since NPC
bypasses an input zone for 60 minutes. If the system “sees” the same
zone trigger three times, and the triggers are spaced less than an hour
apart, the system bypasses that input zone for 60 minutes.
If that zone does not attempt to trigger the system during the 60-minute
bypass period, the zone’s monitoring begins again at the end of the
hour. If it does attempt to trigger while bypassed, the 60-minute bypass
starts over again.
Disarming and rearming the system does not reset NPC. The only way
to reset NPC™ is for the 60 minutes to pass without a trigger, or for
the ignition to be turned on. This allows the system to be repeatedly
triggered, disarmed and rearmed, and still allows NPC to bypass a
faulty zone.
When disarming the system, 5 chirps indicate NPC is activated. The
LED reports the zone that has been bypassed. (See Diagnostics section
of this guide.)
