1-4 ACTIVE/PASSIVE LOCKING: If passive arming is selected in Feature 1-1, then the system can be programmed
to either lock the doors when passive arming occurs, or only lock the doors when the system is armed via the
transmitter. Active locking means the system will not lock the doors when it passively arms. Passive locking means
that the system will lock the doors when it passively arms.
NOTE: Remember, when passive arming is selected, the unit will chirp 20 seconds after the last door
is closed. The system does not actually arm or lock the doors until 30 seconds after the door has
been closed.
1-5 PANIC WITH IGNITION ON: This feature controls whether or not the panic mode is available with the igni-
tion on. In some states, there are laws prohibiting a siren sounding in a moving vehicle. This feature makes the
system compliant with these regulations.
1-6 DOOR LOCK PULSE DURATlON: Some European vehicles, such as Mercedes-Benz and Audi, require longer lock
and unlock pulses to operate the vacuum pump. Programming the system to provide 3.5 second pulses, will
accommodate the door lock interface in these vehicles. The default setting is 0.8 second door lock pulses. Some
modification to the door lock harness (H2) is also necessary. (See (+/-) Door Lock Outputs Harness (H4) section,
"Type E - Mercedes-Benz and Audi -1985 and Newer" diagram.)
1-7 FORCED PASSIVE ARMING ON/OFF: To use this feature, passive arming must be selected in Feature 1-1. When
turned on, forced passive arming will ensure that the system will passively arm, even if a zone is left open or
invalid. Forced passive arming occurs one hour after the ignition is turned off.
1-8 AUTOMATIC ENGINE DISABLE (AED) ON/OFF: AED is a full-time, passive starter disable that works inde-
pendently of the security system. When turned on, the orange, ground-when-armed output (H1/1) will activate
30 seconds after the ignition is turned off. The LED will flash at half its normal rate when the ignition is turned
off to indicate that AED is active and will interrupt the starter in 30 seconds. AED does not occur in Valet® mode
and can be bypassed using the emergency override procedure. The transmitter can be used to disarm AED,
however, the system must be armed and then disarmed, using the transmitter, to disarm AED.
1-9 ARMED WHILE DRIVING (AWD) ON/OFF: In the default setting (Armed While Driving), the system can be
armed with the ignition on. When armed, the ground-when-armed is not active and the sensors are bypassed. The
door triggers will remain active.
1-10 CODE HOPPING ON/OFF: The system uses a mathematical formula to change its code each time the trans-
mitter 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 Code Hopping™ feature lets
the receiver ignore the Code Hopping™ part of the transmitted word. As a result, the unit may have better range
with Code Hopping™ off.
