TWO STAGE INFRASONIC
SHOCK SENSOR
AS-9495-4P (NR)
Printed In Taiwan
Form No. 128-5858
MOUNTING THE SHOCK SENSOR:
Never mount the sensor outside the vehicle where it will be exposed to the elements. Never mount any compo-
nent near hot or moving parts. Always mount the components and route the wiring away from the rotating steering
shaft assembly.Always mount the sensor within 22" of the alarm module to assure the plug in cable reaches the
sensor.
1. Select a solid mounting location inside the vehicle. Ideally the inside firewall, center of the vehicle is best for
sensitivity. An alternate location can be the "A" pillar,"B"pillar, or suspended from an existing brace or wiring
harness.
2. Mount the sensor using the two screws provided or cable ties securing it to your chosen location.
CONNECTING THE SENSOR:
1. Connect the large 4 pin connector of the wiring harness to the 4 pin mating connector on the AS-9495-4P (NR).
2. Route the small 4 pin connector of the harness toward the alarm control module and connect it to the mating 4
pin connector on the alarm unit.
SENSITIVITY ADJUSTING:
Note: The shock sensor's LED's will not operate unless the alarm system is armed.
Thesensitivityofthepre-detectstage, (indicatedbytheRedLEDflashingrapidly), andfulltriggerstage, (indicated
by the Red LED turning on momentarily) are set with one setting. The pre-detect stage will operate at 30% less
force than the full trigger stage.
1. Arm your alarm system than firmly strike the windshield pillar with the open palm of the hand considering the
force required to break the vehicle glass. If the alarm system triggers easily, disarm your alarm, turn the
adjustment screw located on the sensor counterclockwise to decrease the units sensitivity, and repeat the
above test. If the siren emitted a few short bursts (pre-detect) no further adjustment is necessary.

Note: Proper sensitivity level is dependent mostly upon technician preference, mounting location, and vehicle
size. Always consider the effect of setting the sensitivity level too high. This will cause false triggers due to
environment noise and passing vehicle vibrations. Keeping your settings at a minimum will prevent these prob-
lems.
