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.
