Occupancy Sensor
LOS-C Series
Installation Instructions
Description
The LOS-C Series of ceiling-mounted sensors incorporate ultrasonic (CUS), infrared (CIR), and dual
technologies (CDT). They integrate into Lutron
R
systems or function as stand-alone controls using a
Lutron
R
power pack.

• Dry contact closure available on -R models
• LED indicators: Ultrasonic (US)-green, Infrared (IR)-red, Dual Tech (DT)-red and green
• 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, hanging fixtures, etc.
• For -CIR 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 -CDT and -CUS 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.
• If installing a 180° occupant sensor, place the sensor on the same wall as the doorway so that hallway traffic
will not affect the sensor; otherwise, place in center of room.
• 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 range is when unit is mounted on an 8 ft to 12 ft (2.4 m to 3.7 m) ceiling.
