Sensors
Sensors have no user controls. Simply install two AAA
alkaline batteries and Sensors begin working. The bat-
teries will last for about two years of continuous use. The
detection zone (See Figure 1) extends out from the lens
of the Sensor. Best performance is achieved when the
target being detected passes through the detection zone
from left to right or right to left.
The detection range from the Sensor varies with the
difference in temperature between the target and air
temperature. During winter a target may be detected at
a distance of 75 feet or more from the Sensor. However
during hot weather this distance may be reduced to less
than 30 feet. The Sensors should be set to a height that
is at the center mass of the target being detected. Use
this information when setting up your Sensors.
