Pre-Installation
A Before associating the sensor, install the corresponding dimming or switching device(s).B Twist and remove the mounting bracket to insert the battery into the battery cavity.C Associate sensor with a corresponding dimming or switching device/system.D Before mounting the sensor, please note the following sensor placement information:
- The sensor is designed for ceiling use only. DO NOT install on ceilings higher than 12 ft (3.7 m).
- The sensor should be installed in a location where it has a good view of all parts of the room. The sensor requires line-of-sight to operate properly. If you cannot see thesensor, it cannot see you. The sensor cannot see through glass objects such as patio or shower doors.
- DO NOT mount the sensor within 4 ft (1.2 m) of HVAC vents, halogen or incandescent light bulbs, microwave ovens, Wi-Fi routers, IoT cameras, or other non-clear Connect wireless devices. When using Clear Connect – Type X lamps or fixtures, ensure the sensor is mounted at a distance of 2 ft (0.6 m) or greater from the lamp or fixture.
- The sensor may be installed up to 60 ft (18.3 m) away from the associated dimming or switching device(s) if they are in direct line of sight. If there are walls or other barriers between the sensor and receiving device(s), the sensor should be located within 30 ft (9.1 m).
- Whenever possible, avoid placing the sensor in a location where it has a broad view outside of the intended space. If this is unavoidable, the lens can be masked toblock the view of undesired areas.
Installation
Mounting
- Drop-Ceiling Mounting
a Place the mounting wire through the mounting bracket and pierce ceiling tile in the desired location. From the opposite side of the tile, slip the Ceiling Tile Backer through both legs of the wire.b, Twist the wire tightly to prevent sensor sagging. The Ceiling Tile Backer will prevent the tile from breaking. - Solid-Ceiling Mountinga Drill two 3/16 in (4.6 mm) pilot holes for the provided screw anchors.b Press the anchors into the holes and tap flush with a hammer.c Place the flat side of the mounting bracket against the ceiling and install the two provided screws using a hand screwdriver.d Attach the sensor to the mounting bracket by inserting and twisting in a clockwise direction until the sensor locks into place.
Testing Sensor Coverage
- With the sensor mounted on the ceiling, press and release the “Test” button. The lens will glow briefly, indicating the test mode has been entered.NOTE: There is a warm-up period of 90 seconds after the battery is installed before the test mode is activated. If the button is pressed during this time, the lens will flash continuously until the warm-up period is complete, and then the test mode will be automatically entered.
- Confirm the coverage area by walking through the space and observing the lens. The lens will glow solid every time motion is detected. If the lens remains off during motion, the sensor cannot detect motion at that location.
- Press and release the “Test” button again to exit the test mode. If the button is not pressed, the test mode will automatically time out 15 minutes after being enabled, or 5 minutes after the last detected motion if the room is vacated.
- If the sensor has significant trouble detecting motion during the test, it should be moved to another location and re-tested.
Testing Wireless Communication
This test should be performed to verify that the sensor has been correctly set up with the corresponding dimming or switching device and that there is proper wireless communication from the chosen sensor location.Press and release the “g” button multiple times to toggle the lights on and off.
Advanced Set-Up
The sensor features several advanced set-up modes. For the majority of installations, the default settings will provide the best performance and you will not need to utilize the advanced setup. If you determine the default settings require adjustment, refer to the back of the sensor. The sensor has three adjustable advanced set-up modes: Auto-On, Activity, and Timeout. The default settings are listed below.

Advanced Set-Up ModesAuto-On
The automatic-on functionality of the sensor can be adjusted to control how the lights respond upon initial occupancy. There are three available settings: Enabled, Low Light, and Disabled.Enabled: The lights will always turn on.Low Light: The lights will only turn on automatically if there is not already sufficient ambient light in the room.Disabled: This setting converts the sensor to vacancy-only mode. The lights will not automatically turn on but will still automatically turn off after vacancy. The lights must be manually turned on by using the associated dimming or switching device.
ActivityThe sensitivity of the sensor can be adjusted based on the expected level of activity within the area. There are three available activity settings: Low Activity, Medium Activity, and High Activity.Low Activity: This is the most sensitive setting and will detect very slight motions. This is the recommended setting, as it will work well for nearly all applications. It is ideal for spaces where occupants will often be seated for long periods of time.Medium Activity*: This setting is slightly less sensitive than the Low Activity setting and can be used for spaces that experience normal activity.High Activity*: This is the least sensitive setting and can be used for spaces that will generally only experience large motions, such as foot traffic.
TimeoutThe sensor will turn the lights off if no motion occurs for the duration of the timeout period. There are four available timeout settings: 1**, 5, 15, and 30 minutes.
The Low Activity setting is the default and will perform best for most applications. Rarely, if the sensor is placed near external noise sources such as heating vents, air conditioning vents, or light bulbs, it may turn the lights on without occupancy or keep the lights on too long after vacancy. If this occurs, change the sensitivity to Medium Activity or High Activity to resolve the problem.
To select a 1-minute timeout, press and hold the timeout button for approximately 10 seconds until all three LEDs begin flashing rapidly. To save the 1-minute timeout setting, press and hold the timeout button until all three LEDs turn on solid, indicating the 1-minute timeout has been saved.

Product Description
Lutron ceiling-mounted occupancy sensors are wireless, battery-powered, passive infrared (PIR) devices that automatically control lights via RF communication with a dimming or switching device.
Grace Period
In vacancy mode (Auto-On, disabled) there is a built-in 15-second vacancy grace period that begins when the lights are automatically turned off, during which the lights will automatically turn back on in response to the motion. This grace period is provided as a safety and convenience feature in the event that the lights turn off while the room is still occupied so that the user does not need to manually turn the lights back on. After 15 seconds, the grace period expires and the lights must be manually turned on.
NOTE: The lights can be manually turned off at any time by using the receiving device directly. If the lights are turned off manually, the room must be unoccupied for the duration of the timeout period of the Sensor before the lights will turn back on in response to occupancy.
Important Notes
- This sensor is part of a system and cannot be used to control a load without a compatible dimming or switching device. Refer to the instruction sheets of the receiving device(s) for installation information.
- Clean sensor with a soft damp cloth only. DO NOT use any chemical cleaners.
- The sensor is intended for indoor use only. Operate between 32 °F and 104 °F (0 °C and 40 °C).
- DO NOT paint the sensor.
- Use only high-quality lithium batteries, size CR123, 3 V- (ANSI-5018LC, IEC-CR17345). DO NOT use rechargeable batteries. Using improperly-rated batteries could damage the sensor.
- The range and performance of the RF system is highly dependent on a variety of complex factors such as:
- Distance between system components
- The geometry of the building structure
- Construction of walls separating system components
- Electrical equipment located near system components
