Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder, inclination sensor, and
intrusion sensor.
The power sounder provides an
audible alarm, which is distinct from
the vehicle’s horn. It has its own
power source, and can sound an alarm
if the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation.
The intrusion sensor monitors the
vehicle interior, and can activate the
alarm if it senses unauthorized entry
into the vehicle’s interior. Do not
allow passengers or pets to remain in
the vehicle when the intrusion sensor
is activated.
