4 Wire Polarity Reversal and
5 Wire Alternating 12 Volt
Door Lock Control Circuits
In these applications, the AS 9159 Door Lock Interface ( or equivalent 30 A automotive relays ) must be
used. Refer to the AUDIOVOX Door Lock Wiring Supplement for proper connection to these types of
circuits.
COMPLETING THE INSTALLATION
Antenna Wire : Be sure to extend the thin black antenna wire to it’s full length, and cable tie into place
where it cannot be damaged. Avoid wrapping this wire around major, high current wire looms.
Adjusting the OPTIONAL Shock Sensor : Using a small screwdriver, gently turn the adjustment screw
fully counterclockwise. ( DO NOT over turn this screw. Maximum rotation for this adjustment is 270° ).
Close the hood and trunk lids, and arm the alarm. Wait 6 seconds for the accessories trigger zone to
stabilize, then firmly strike the rear bumper with the side of a closed fist considering the amount of force
required to break a window .
CAUTION : Never perform this test on the vehicle’s glass, as you may break the window.
Turn the adjustment screw clockwise ( increasing sensitivity ) about ¼ turn and re - test. Repeat this
procedure until the alarm sounds. Ultimately, one very firm strike to the rear bumper will cause the alarm to
sound.
WARNING ! Setting the sensitivity too high can cause false alarms due to noise vibrations from passing
trucks and heavy equipment. To decrease sensitivity, turn the adjustment screw counter clock-
wise.
Wire Dressing : Always wrap the alarm wires in convoluted tubing, or with a spiral wrap of electrical tape.
Secure these looms along the routing using cable ties. This will ensure that the alarm wires are not
damaged by falling onto hot or sharp moving surfaces in the vehicle.
Operation : Take a few moments to check off the appropriate option boxes in the owner’s manual, and to
fully explain the operation of the system to your customer.
