accommodate door lock interface in these vehicles. The default setting is 0.8 second door lock pulses. See
Mercedes-Benz and Audi - 1985 and Newer (Type E Door Locks section) diagram.
6 DOUBLE PULSE UNLOCK OFF/ON: Some vehicles require two pulses on a single wire to unlock the doors. When
the double pulse unlock feature is turned on, the H2/2 BLUE/BLACK wire will supply two pulses instead of a
single pulse. This makes it possible to directly interface with double pulse vehicles without any extra parts.
NOTE: The second unlock output feature (H3/1 BLUE wire) is not available if the double pulse
unlock feature is turned on.
7 STEALTH CODING ™ TECHNOLOGY ON/OFF: This system features Stealth Coding ™ Technology as an option.
Stealth Coding ™ Technology is a feature that uses a mathematical formula to change the system’s code each time
the transmitter and receiver communicate. This makes the group of bits or "word" from the transmitter very long.
The longer the word is, the easier it is to block its transmission to the unit. Disabling the Stealth Coding ™
Technology feature lets the receiver ignore the Stealth Coding ™ Technology part of the transmitted word. As a
result, the unit may have better range with Stealth Coding ™ Technology off.

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.)
