3-5 CRANK TIME 0.6/0.8/1.0/1.2/1.4/1.6/1.8/2.0/4.0 SECONDS: If the unit is programmed for no engine
checking or voltage sense, the crank time must be set to the appropriate duration. The default setting is 0.6
second. If a different crank time is desired, select feature 3-5 and select either 0.6 second by using the one-
chirp setting or toggle through the higher settings by using the two-chirp settings.
3-6 VOLTAGE CHECK HI/LOW: This feature only functions when programmed for voltage sense. Some vehicles
have many accessories, which are turned on when remote started. In these vehicles, the variation of voltage
between the engine off and the car running is very small and the remote start unit may "think" the vehicle has
not started. This can cause the remote start to shut-down after the car has been started. If this happens program
this feature to the LOW position.
3-7 AUXILIARY OUTPUT FACTORY DISARM/SPECIAL ACCESSORY: In the default setting this wire sends a nega-
tive pulse that may be used to disarm the vehicle’s factory security system. If programmed for a special accessory,
the wire can be used to energize a relay to power up extra ignition wires in the vehicle. This wire must be used
to energize circuits in the vehicle that operate accessories, such as the radio or heater.
3-8 BLUE WIRE STATUS OUTPUT/FACTORY SECURITY RE-ARM OUTPUT: The blue (H3/1) wire will supply a 200mA
(-) output for the entire remote start run time. If programmed for factory re-arm output, this wire will supply a
momentary 200mA (-) pulse whenever the remote start times out or is shut down with the transmitter. This can
be used to re-arm many factory security systems.
3-9 AUTOMATIC ANTI-GRIND ON/OFF: With the anti-grind ON (default) the ground-when-armed output will be
active during remote start operation. If accessories such as a voice module or window module are added to the
unit, it may be necessary to program this feature OFF.
nuisance prevention circuitry
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 Diagnostics section of this guide.)
