Sensors LOS-CDT Series Occupancy Sensors
369653c 1 02.07.13
Dual Technology Ceiling Mount Sensor
The LOS-CDT Series dual technology ceiling-mount
sensors can integrate into LutronR systems or function
as stand-alone controls using a LutronR power pack.
The technology eliminates manual sensitivity and timer
adjustments during installation and over the life of the
product.
Features
Intelligent, continually adapting sensor
Ultrasonic (US) combined with Passive Infrared (PIR)
sensing provide high sensitivity, high noise immunity,
and excellent false tripping immunity
Suited for complex environments that are difficult to
control with single-technology sensors
Snap-locks to ceiling-mounted cover plate
Non-Volatile Memory: settings saved in protected
memory are not lost during power outages
500 ft( to 2000 ft( (46 m( to 186 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.

Self-Adaptive Feature
The LOS-CDT Series sensors combine both Ultrasonic
(US) motion detection for maximum sensitivity and
Passive Infrared (PIR) motion detection for false
triggering immunity. The self-adapting internal
microprocessor analyzes the composite sum of both
signals to eliminate time-consuming adjustments and
callbacks found in non-intelligent sensors.

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.

Sensor Placement
Range Diagrams
Mount the sensor so the grilles face the open portion of the room and are not facing a nearby wall, window, or
other obstructing object.
Do not place sensor within 6 ft (1.8 m) of air vents, air handlers, windows, fans, etc., as this may cause false
triggering.
If installing a 180° occupancy sensor (500 and 1000 models), place the sensor on the same wall as the doorway
so that traffic in a hallway will not affect the sensor; otherwise, place in center of room.
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).
Decrease total coverage area by 15% for “soft” rooms (e.g. heavy draperies or thick carpeting).
LOS-CDT-1000
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).

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

1. Place timer in Test Mode (see page 8).
2. Set photo cell to maximum. Turn the blue knob full
clockwise (lights on no matter how bright the natural
light is), then about 30° counterclockwise.
3. 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.
4. Adjust to desired level. If lights remain off, adjust the
blue knob another 30° counterclockwise and repeat
step 3 until the lights turn on.
NOTE: Set blue knob to 100% to disable photo cell
functionality and leave secondary dry contact closure
output functionality intact.
