Sensors LOS-CIR Series Occupancy Sensors
369655c 1 02.07.13
Infrared Ceiling Mount Sensor
The LOS-CIR Series passive infrared ceiling-mount
sensors can integrate into LutronR systems or function
as stand-alone controls using a LutronR power pack.
The sensor uses a small semiconductor heat detector
that resides behind a multi-zone optical lens. The
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 (PIR) 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 ft( to 1500 ft( (42 m( to 140 m() coverage when
mounted on an 8 ft to 12 ft (2.4 m to 3.7 m) ceiling
Affords choice of turning lights off or dimming to a
preset level in the unoccupied state when integrated
with a LutronR system.
Models Available
Model Color Coverage Field of View
LOS-CIR-450-WH White 450 ft( (42m() 360°
LOS-CIR-1500-WH White 1500 ft( (140m() 360°
Self-Adaptive Feature
The LOS-CIR Series sensors provide 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.

Power packs may be required when interfaced to LutronR lighting control systems. If more than 1 occupancy
sensor is connected to the same input, a power pack is required. A maximum of 3 occupancy sensors can be
connected to the same input. If more than 3 sensors are required per input, use one of the following models:
LOS-CDT-500R-WH, LOS-CDT-1000R-WH, or LOS-CDT-2000R-WH.

Range Diagrams
The occupancy 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 4 ft (1.2 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 (e.g. person taking a half-step) at a greater distance than it can detect minor motion (e.g. writing at a
desk or reading a book).
May not detect occupancy with no significant difference between ambient and body temperatures.
Sensor Setup
Sensor setup is available as a service by Lutron. For more information see the Sensor Layout and Tuning
service document (LutronR P/N 3601235).

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.
