Solid-Ceiling Mounting
• Drill two 3/16 in (4.6 mm) pilot holes for the provided
screw anchors.
• Press the anchors into the holes and tap flush with a
hammer.
• Place the flat side of the mounting bracket against the ceiling
and install the two provided screws using a hand screwdriver.
• Attach the Sensor to the mounting bracket by inserting and
twisting in a clockwise direction until the Sensor locks into
place.
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. NOTE: If the Sensor is detecting motion in areas that are not desirable, such as
hallways or adjacent rooms, refer to www.lutron.com/occsensors
If Sensor detection is satisfactory during this test, perform the wireless communication test as described in
section G. Testing Wireless Communication.
This test should be performed to verify 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 “Light” button multiple times to toggle the lights on and off.

Troubleshooting
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 set-up.
The Occupancy version of the Sensor has three adjustable advanced set-up modes:
Timeout, Auto-On, and Activity. The Vacancy-Only version has only two modes
(Auto-On not available). The default settings are listed below.
Default Settings:
Timeout: 15 minutes
Auto-On: Enabled
(Occupancy version only)
Activity: Low Activity
Advanced Set-Up Modes
Timeout
The 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.
Auto-On (Occupancy version only)
The automatic-on functionality of the Sensor can be adjusted to control how the lights respond upon
initial occupancy. There are three available settings: Always, Low light, and Disable.
Enabled: The lights will always turn on.
Low light: The lights will only turn on automatically upon entry if there is not already sufficient
ambient light in the room.
Disabled: This setting converts the Sensor to vacancy 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.
Activity
The sensitivity of the Sensor can be adjusted based on the expected level of activity within the room.
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.
* To select a 1-minute timeout, press and hold the timeout button for approximately 10 seconds until all
3 LEDs begin flashing rapidly. To save the 1-minute timeout setting, press and hold the timeout button
until all 3 LEDs turn on solid, indicating the 1-minute timeout has been saved.
** 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,
changing the sensitivity to Medium Activity or High Activity should resolve the problem.
