mux (multiplex) sensors
adjusting the 506T glass tamper sensor
NOTE: Before testing, all the doors and windows must be shut. If a window is open,
the acoustics of the vehicle interior change dramatically. The customer should be
informed of this. Also remember that Clifford security systems cannot trigger until ten
seconds after they are armed.
A single tap of a key or a coin should not trigger the sensor, since it is designed to
react to multiple, closely-grouped sounds. A sharp rap with a set of keys should trig-
ger the sensor. If the sensitivity needs to be increased, turn the adjustment screw clock-
wise an eighth of a turn and retest. If the sensitivity needs to be decreased, turn the
adjustment screw counter-clockwise and retest.
adjusting and testing the 509U ultrasonic sensor
1.
The sensitivity adjuster is found on the top of the 509U control module. Insert a
small screwdriver into the adjustment hole and turn the screw clockwise to
increase sensitivity or counterclockwise to decrease sensitivity.
2. Arm the alarm system, wait a few seconds and then move your arm through an
open window on the vehicle as if attempting to remove an item from the seat.
The LED should illuminate on the control module to provide visual indication it
has detected the movement and the alarm system should trigger.
If it does not, then increase the sensitivity in small increments until the optimum
position is reached and the sensors do pick up the movement. Do not over adjust
the sensors as the system will false alarm. The sensitivity level should be left at
the minimum setting where the sensors pick up movement in the rear seating
position.
3. When satisfied with the final sensitivity setting, mount the 509U control module
securely with the double-sided tape and cable tie provided.
adjusting the 507C tilt/motion sensor
The unit has 2 wire loops (one WHITE and the other BLACK) for setting both the tilt
threshold and the arming delay. The 2 wire loops are located on the side of the sensor
next to the harness plug.
TILT SENSITIVITY THRESHOLD
The BLACK loop controls the tilt sensitivity threshold that detects when the vehicle is being
lifted. A 1-degree threshold is the default setting for extreme sensitivity. If the BLACK
