NPC™ requires that you change the way you test the system, as NPC™ will bypass 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 will bypass 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 will begin 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 allow NPC™ to bypass a faulty zone.
When disarming the system, 5 chirps indicate NPC is activated. The LED will report the zone that has been
bypassed. (See
Table of Zones
section of this guide.)

When using the Diagnostic functions, use the Table of Zones to see which input has triggered the system. It is
also helpful in deciding which input to use when connecting optional sensors and switches.
ZONE NO.
TRIGGER TYPE
INPUT DESCRIPTION
1
Multiplex
H1/6 BLUE wire. Connects to optional hood/trunk pins or
an optional sensor. Inputs longer than 0.8 seconds will
instantly trigger the full alarm sequence and report Zone 1.
2
On-board impact sensor
Second-stage of on-board impact sensor (heavy impacts
from impact sensor).
3
Two-stage, progresses from
Door switch circuit. H1/5 GREEN or H1/7 VIOLET.

5
Two-stage, progresses from
Ignition. H1/9 YELLOW.

: The Warn-away response does not report on the LED.
