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 bypasses, that sensor or switch (along with any

other sensors or switch es sharing the same zone) for 60 minutes.

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 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.

note: Arming and disarming the system does not
reset this function! The only ways to reset a bypassed
zone are for it to not trigger for 60 minutes, or to turn
on the ignition. 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
