mux sensors
audio sensor
The 506T Audio Sensor is a low-current device that provides an added level of protec-
tion to an existing security system by detecting sounds that have the acoustic signature
of breaking glass or metal-to-glass impacts. It consumes less than 1 mA of current.
adjusting the audio 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 three
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 an
eighth of a turn and retest. If the sensitivity needs to be decreased, turn the adjustment
screw counter-clockwise and retest.
shock sensor
The 504C dual zone magnetic resonance shock sensor provides a warning trigger for
lighter impacts to the vehicle as well as a full trigger for heavy impacts.
mounting the shock sensor
Mount the 504C sensor with wire ties or double-sided tape. Air ducts or wiring har-
nesses work well for mounting, although it is best to avoid harnesses containing light-
ing circuits.
adjusting the shock sensor
To adjust the sensor, turn the sensor screw clockwise for higher sensitivity or counter-
clockwise for less sensitivity.
