Description
The LOS-W Series of wall-mounted sensors incorporate infrared (WIR) and dual technologies (WDT) -
ultrasonic and infrared. They are used in spaces with pendant fixtures, ceiling fans, or high ceilings. They
integrate into Lutron
R
systems or function as stand-alone controls using a Lutron
R
power pack.

• LED indicators: Ultrasonic (US)-green, Infrared (IR)-red
• For indoor use only
Coverage and Placement
• The occupant sensor must have an unobstructed view of the room. Do not mount behind or near tall cabinets,
shelves, indirect hanging fixtures, etc.
• For -WIR models, do not place sensor within 4 ft (1.2 m) of air vents, air handlers, windows, fans, etc., as this
may cause false triggering.
• For -WDT and -WDT-R models, do not place sensor within 6 ft (1.2 m) of air vents, air handlers, windows,
fans, etc., as this may cause false triggering.
• Place the sensor on the same wall as the doorway so that hallway traffic will not affect the sensor.
• Closely follow the diagrams for major and minor motion coverage.
• Decrease total coverage area by 15% for “soft” rooms (e.g. heavy draperies or heavy carpeting).
• Indicated coverage is when sensor is mounted at 8 ft (2.4 m) high.
