2-4 PROGRESSIVE DOOR TRIGGER ON/OFF: The system responds to a door trigger input with a progressive
response. When the door is opened with the system armed, the siren will chirp 10 times prior to the full trig-
gered sequence. The door trigger is still treated as an instant trigger and closing the door quickly will not prevent
a full triggered sequence from occurring. If the progressive door trigger is programmed off, the full siren output
will occur the moment the door is opened.
2-5 VALET PULSE COUNT 1 to 5 PULSES: The system can be programmed to count the number presses of the
valet switch before disarming the security system or VRS
be set for 2 to 5 pulses using the two-chirp setting to select the pulse count.
GHOST SWITCH OPTION: For added security, the GRAY wire on the two-pin Valet
connected to any switch in the vehicle that provides a positive (+) momentary pulse.
2-6 DOOR TRIGGER ERROR CHIRP ON/OFF: With the door trigger error chirp programmed off, the system will not
report an invalid zone on arming when the door trigger wire is active. This eliminates the extra chirps that occur
when interfacing with vehicles that have exceptionally long dome light delay circuits.
2-7 IGNITION-CONTROLLED DOMELIGHT SUPERVISION ON/OFF: If turned on, the system will turn on the dome-
light for 30 seconds when the ignition is turned off. The optional domelight supervision feature must be installed.
2-8 DOUBLE PULSE UNLOCK ON/OFF: 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 positive pulses instead of a single pulse.
This makes it possible to directly interface with double pulse vehicles without any extra parts.
2-9 CHANNEL 3 VALIDITY/LATCHED/LATCHED RESET WITH IGNITION/30 SECOND TIMED/SECOND UNLOCK
OUTPUT: Channel 3 can be programmed for these output configurations. The unit is set to the default validity
output. To change the configuration, use the two-chirp setting to toggle to the different configurations.
