Dual sensors
Your AvantGuard III system has both a Digital Dual-Zone Proximity Sensor IV and a
Dual-Zone Piezo Sensor.
The Digital Dual-Zone Proximity Sensor IV is a microprocessor-controlled passenger
compartment radar sensor that provides full perimeter protection: If someone is lurking
near your car, the sensor’s exterior warning zone will trigger the system to sound a
one-second warning tone, but if a thief actually leans into the passenger compartment
through an open window or tries to cut through a soft-top, the sensor instantly triggers
the system to blast the siren, flash the side lights and immobilise the starter and ignition
system. What’s more, thanks to Clifford Electronics’ advanced engineering, this
new-generation radar sensor uses only 30% of the power required by other radar sensors
(so it won’t drain your car battery), yet provides better sensitivity and far more precise
discrimination between genuine threats to your vehicle and everyday environmental
conditions that cause other radar sensors to false alarm.
The Dual-Zone Piezo Sensor is an all-electronic vibration/impact sensor. If someone
forcefully leans on your parked vehicle or lightly taps the bumper while parking, the
Piezo Sensor’s warning zone will cause the system to issue a warning (a different sound
than that triggered by the Proximity Sensor, so you can easily distinguish between the
two). However, if there is any genuine intrusion-related tampering, the Piezo sensor will
instantly trigger the system to blast the siren, flash the side lights and immobilise the
starter and ignition system. Unlike other vibration/impact sensors, the sensitivity
settings of the Dual-Zone Piezo Sensor are impervious to temperature variations.
Both sensors are completely adjustable by you with just a few presses on your remote
control. This makes it particularly easy to reduce the sensitivity a few steps when, for
instance, in a vibration-prone parking area such as a busy road with large trucks and
buses passing close to your vehicle.
Remote controlled sensor adjustments
Unlike other alarm sensors, you can adjust sensitivity of the two system sensors
electronically without tools and without even knowing where they are mounted! If the
setting(s) of the Dual-Zone Proximity Sensor IV and/or Dual-Zone Piezo Sensor are
either too sensitive or not sensitive enough, you may individually test and adjust the
settings of each zone. To make adjustments, just use the following procedure:
1. Disarm the system with the remote control, open the driver’s window (if adjusting
the Proximity Sensor), then select the sensor and sensor zone you wish to adjust:
a. Proximity Sensor interior alarm zone: Transmit channel 11 (LevelShift twice,
then button 3).
b. Proximity Sensor exterior warning zone: Transmit channel 12 (LevelShift twice,
then button 4).
c. Piezo Sensor primary alarm zone: Transmit channel 15 (LevelShift three times,
then button 3).
d. Piezo Sensor secondary warning zone: Transmit channel 16 (LevelShift three
times, then button 4).
2. To test the current sensitivity setting of the sensor zone you selected:
