Lutron Electronics LOS-WIR, LOS-W, LOS-WDT-R, LOS-WDT Installation Instructions Manual

OCCUPANT SENSOR
LOS-W SERIES
Installation Instructions Please Read

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

FEA

TURES

• Intelligent, continually adapting sensors

• 20-24 V , Class 2 (PELV) low voltage, 33 mA nominal

• 1600 sq.ft. coverage

• Flexible mounting on wall or ceiling

• Second dry contact closure output available on R models

• 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 entrance. Do not mount behind or near
tall cabinets, shelves, indirect hanging fixtures, etc.

• Keep the occupant sensor away from air flow.

• 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 (for example, heavy draperies or heavy carpeting).

• Indicated coverage is when sensor is mounted at 8 ft. high.

Adjusting the “Lights Not On”

Level: LOS-WDT-R only

1. Ensure that the ambient light is at the desired level.

2. Place sensor in Test Mode: Press and release black pushbutton.

3. Set photo cell: Turn the blue knob full clockwise (lights on no matter how bright the natural light is), then about 30
degrees counterclockwise.

4. Check for Lights-Out: Move from underneath the sensor, and remain still until the lights turn off. Move around normally
to turn the light on.

5. Adjust to desired level: If lights turn on, adjust the blue knob another 30 degrees counterclockwise and repeat step 3
until the lights remain off.
Note: Set blue knob to 100% to disable photo cell functionality and leave secondary dry contact closure output func­tionality intact.

Note: Not all models have every knob.
