For motion sensing models only—Mount the sensor
on a wall that will have an unobstructed view of the
typical traffic in the coverage area. When choosing
a location, do not install the sensor in the following
areas.
◆ ◆
Behind curtains or other obstructions
◆ ◆
In locations that will expose it to direct sunlight or
heat sources
◆ ◆
Near a heating or cooling inlet or outlet.
The effective detection range is approximately 10
meters or 33 feet. Factors that may reduce the range
may include the following items.
◆ ◆
The difference between the surface temperature of
the object and the background temperature of the
room is too small.
◆ ◆
Object movement in a direct line toward the
sensor.
◆ ◆
Very slow or very fast object movement.
◆ ◆
Obstructions in the shaded area of the diagram
Typical motion sensing coverage.
False detections may be triggered by any of the
following conditions.
◆ ◆
The temperature inside the detection range
suddenly changes because of the entry of cold or
warm air from an air-conditioning or heating unit.
◆ ◆
The sensor being directly exposed to sunlight, an
incandescent light, or other source of far-infrared
rays.
◆ ◆
Sma ll animal movement.
