feature descriptions
1 ACTIVE/PASSIVE ARMING: When active arming is selected, the system will only arm when the transmitter is
used. When set to passive, the system will arm automatically 30 seconds after the ignition is turned off. Passive
arming is indicated by the rapid flashing of the LED.
2 ARM/DISARM CONFIRMATION HONKS ON/OFF: This feature controls the horn honks that confirm the arming
and disarming of the system.
3 IGNITION CONTROLLED DOOR LOCK ON/OFF: When turned on, the doors will lock three seconds after the igni-
tion is turned on.
4 IGNITION CONTROLLED DOOR UNLOCK ON/OFF: When turned off, the doors will unlock when the ignition is
turned off.
5 ACTIVE/PASSIVE LOCKING: If passive arming is selected in Feature 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 trans-
mitter. 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.
6 IGNITION CONTROLLED DOMELIGHT: If turned on, the system will turn on the domelight for 30 seconds when
the ignition is turned off. The domelight supervision output (H1/4) wire must be connected to an optional relay
as described in the Primary Harness Wire Connection Guide.
7 DOOR LOCK PULSE DURATION: 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 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.
8 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 BLUE H2/C wire will supply two negative pulses instead of a
single pulse. At the same time, the GREEN H2/A 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.
9 SECURITY FEATURES ON/OFF: In the ON setting the (-) ground-when-armed output will be active and can be
used to operate starter kill. The unit will also trigger a panic sequence if the ignition is turned on before dis-
arming the system. Turning the security features off will turn off both the starter kill feature and the triggered
sequence with ignition.
10 CODE HOPPING
ON/OFF: This system features Code Hopping
as an option. To use Code Hopping
technol-
ogy, you must program this feature on. Code Hopping
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.
