GREY AND BROWN WIRES — To automatic door lock/unlock (VS255XR only)
The power door lock outputs may be connected to a car which has existing or add-on power door lock switching
relays. The transistor ground output is high enough to energize most switching relays.
When disarmed, UNLOCKS the doors with a 0.5 second ground output. When armed, LOCKS the doors with a 0.5
second ground output.
DO NOT CONNECT THESE POWER DOOR LOCK WIRES DIRECTLY TO THE DOOR LOCK ACTUATORS, AS
THIS WILL DEFINITELY BURN OUT THE ALARM SYSTEM.
Installation will vary from car to car, depending on the car's power door lock wiring. In most cases, a separate door
lock interface module SEA169 is required. Mercedes and Audi owners will need a different model (SEA168).
Please refer to the module's manual for more information.
ADJUSTING THE SHOCK SENSOR
1. Remove the back cover.
2. Use a small, flat-blade screwdriver to turn the adjustment knob.
3. When turned clockwise, the sensitivity is increased. If turned counterclockwise, the sensitivity is decreased. Do
not overturn the potentiometer, as it may break, only 270 degree adjustment range.
4. To test the sensitivity, kick a wheel lightly, and siren will "chirp," then kick hard enough to trigger the alarm at
the desired point. If it does not "chirp," the sensitivity should be increased. If the wheel is lightly kicked and the
alarm sounds, the sensitivity should be decreased. Check all wheels for consistency.
Note — To prevent false alarms, the shock sensor will not trigger the alarm until 4 seconds after the alarm is armed
and no further motion is detected.
PLUG-IN LED 2-pin RED connector Fig. 7
A. Determine where to mount the LED. The LED should be
easily seen by potential thieves and vandals. However, do
NOT mount where the LED is easily exposed to
sunlight. Discuss the LED location with the customer before starting.
B. Drill a 6 mm hole in the LED location.
C. Run the LED connector through the hole, and then plug into the alarm brain’s 2-pin RED connector.
IMPORTANT The LED operates on +5V, not +12V. DO NOT CONNECT THE LED
DIRECTLY TO THE CARS BATTERY, OR IT WILL BURN OUT.
