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 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
1.
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.
2.
Clean sensor with a soft damp cloth only. DO NOT use any chemical cleaners.
3.
The sensor is intended for indoor use only. Operate between 32 °F and 104 °F (0 °C and 40 °C).
4.
DO NOT paint the sensor.
5.
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.
6.
The range and performance of the RF system is highly dependent on a variety of complex factors
such as:
• Distance between system components
• Geometry of the building structure
• Construction of walls separating system components
• Electrical equipment located near system components
NOTICE: DO NOT disassemble, crush, puncture, or incinerate batteries. DO NOT dispose of batteries in
normal household waste. Please recycle, take to a proper battery disposal facility, or contact your local
waste disposal provider regarding local restrictions on the disposal or recycling of batteries.
CAUTION: Risk of Fire, Explosion, And Burns. Do not recharge, disassemble, heat above
200 °F (100 °C) or incinerate. This product contains a lithium battery. The battery in this device
contains Perchlorate Material — special handling may apply. For more information visit

WARNING: Entrapment hazard. To avoid the risk of entrapment, Serious Injury, or Death, these
controls must not be used to control equipment which is not visible from every control location or
which could create hazardous situations such as entrapment if operated accidentally. Examples of
such equipment which must not be operated by these controls include, but are not limited to:
motorized gates, garage doors, industrial doors, microwave ovens, heating pads, etc. It is the
installer's responsibility to ensure that the equipment being controlled is visible from every control
location and that only suitable equipment is connected to these controls. Failure to do so could
result in serious injury or death.
Sensor Operation
The sensor will automatically turn the lights ON when the space is occupied and automatically turn the
lights OFF after the space is vacated.

Advanced Set-Up
b.
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. 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.
Auto-On

Advanced Set-Up Modes
Auto-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.
Activity
The 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.
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.
*
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.
Possible Cause
Sensor is not correctly associated to dimming / switching device(s).
Auto-On setting is set to "Low light" or "Disabled".
The lights were recently turned off manually and the timeout has not yet expired.
Sensor does not have full view of room.
Sensor is outside wireless range of dimming/switching device.
Battery has been installed incorrectly.
Dimming/switching device has been improperly wired.
Light bulb(s) burned out.
Breaker is off or tripped.
Timeout is too short for this application.
Sensor does not have full view of room.
Lens mask is improperly applied.
Activity setting is too low.
Timeout has not yet expired.
An external noise source (e.g., an HVAC vent) is interfering.
Battery has been installed incorrectly.
Sensor coverage extends beyond room perimeter.
The intended setting was not saved.
Multiple sensors are associated to a dimming/switching device and their settings do not
match.
Sensor cannot see motion due to obstruction.
Room is too big or oddly shaped.
Battery has been installed incorrectly.
An external noise source such as an HVAC vent is interfering.
Sensor is not correctly added to dimming/switching device.
Sensor is outside wireless range of dimming/switching device.
Battery has been installed incorrectly.
Dimming/switching device has been improperly wired.
Light bulb(s) burned out.
Breaker is off or tripped.
Battery is low.
Sensor is in test mode.
