Infrared Ceiling Mount Sensor
The ULOS-CIR Series ceiling-mount passive infrared
sensors can integrate into Lutron systems or function
as stand-alone controls using a Lutron power pack. The
sensor uses a small semiconductor heat detector that
resides behind a multi-zone optical lens. The sensor’s
detector is sensitive to the heat emitted by the human
body. In order to trigger the sensor, the source of heat
must move from one range of detection to another. Non-
moving hot objects will not cause the lights to turn on.
Features
• Intelligent, continually adapting passive infrared
(PIR) sensor
• Passive infrared sensing
• Reliable motion detection with high error immunity
• Snap-locks to ceiling-mounted cover plate
• Non-Volatile Memory: settings saved in protected
memory are not lost during power outages
• 450 to 1500 sq ft (42 to 140 m2) coverage when
mounted on an 8 - 12 ft (2.4 - 3.7 m) ceiling
• Affords choice of turning lights off or dimming to a preset
level in the unoccupied state when integrated with a
Lutron system.
• Assembled in the USA.

Self-Adaptive Feature
The ULOS-CIR Series ceiling-mount occupant sensors provides reliable detection with high error immunity.
The internal microprocessor analyzes the information from the PIR technology and determines the optimum
setting to use in order to properly cover the space.

Sensor Placement
Range Diagrams
• The occupant sensor must have an unobstructed view of the room. Do not mount behind or near tall
cabinets, shelves, indirect hanging fixtures, etc.
• Do not place sensor within 6 ft (1.8 m) of air vents, air handlers, windows, fans, etc., as this may cause
false triggering.
• Closely follow the diagrams shown concerning major and minor motion coverage. The sensor can detect
major motion (such as a person taking a half-step) at a greater distance than it can detect minor motion
(such as writing or typing at a desk).
• May not detect occupancy with no significant difference between ambient and body temperatures.

Sensor Adjustments
Timer Test Mode Factory Settings
1. Remove the retainer cover.
2. Rotate the black timer adjustment knob to about
midway (12 o’clock).
3. Return setting to minimum setting (full CCW).
Note: The timer will remain in the 8-second test
mode for 1 hour, then automatically reset to
8 minutes.
4. To manually take the timer out of the 8-second
test mode, turn the timer adjustment approximately
1/16 in (1.5 mm) clockwise to make the setting
slightly above minimum (just above the 8-minute
setting).
