OPERATION
When the alarm is armed, the ultrasonic unit is automatically activated and fills the
inside of the vehicle invisible sound waves, setting up a steady pattern.
When the alarm’s exit delay has expired (normally 20 seconds), any movement within
the vehicle, banging of the windows or opening of the hatch/boot causes a change in
the ultrasound wave pattern. These disturbances are detected by the unit, triggering
the alarm.
INSTALLATION
Ultrasonic Sensor
The sensors are to be fitted at the top of the ‘A’ posts between the wind-screen and
the side windows. The sensor should face in towards the rear of the car and may be
secured by pushing the ‘tail’ down the back of the plastic trim on the ‘A’ post.
Alternatively, the sensor can be secured by fixing it with the self tapping screws
provided through the hole in the ‘tail’ to the ‘A’ posts.
Ensure that each ultrasonic sensor can be installed facing the rear of the vehicle
without fouling the sun visors.
