Basic Operation
Radar/Impact Sensor
Operation
The SEA-8081 security system comes
standard with a radar (microwave) sensor.
The radar sensor emits a high frequency
signal which is changed when mass move-
ment, from such items as a person’s body or
arm is detected. The SEA-8081 security
system is capable of detecting movement in
two sectors, one inside the vehicle and one
outside the vehicle. The impact sensor will
provide two levels of impact protection, giving
a warning when a light impact is placed on the
vehicle and entering a full alarming state when
a heavy impact is placed on the vehicle.
WARNING (radar sensor)/
PRE-WARN (impact sensor)
MODE
The warning/pre-warn mode controls the type of
coverage provided by the radar and impact
sensors.
When the Warning Mode is ON, the radar sensor
protects two sectors, one inside the vehicle and
one outside the vehicle. When the Pre-warn
mode is ON, the impact sensor will provide two
levels of impact protection, giving a warning
when a light impact is placed on the vehicle and
entering a full alarming state when a heavy
impact is detected. When the Warning/Pre-warn
Mode is OFF, the radar sensor will only protect
the sector inside the vehicle while the impact
sensor will respond only to heavy blows to the
body of the vehicle.
