These Sensors detect the heat from people moving within an area to determine when the space is occupied. The Sensors then transmit the appropriate commands to the associated dimming or switching device to turn the lights on or off automatically, providing both convenience and exceptional energy savings. Easy-to-follow Instructions P/N 041-172a Key Features Low Maintenance. 10-year battery life. Convenient low-battery indicator. Multiple Devices. Up to 3 Sensors can work together to control lights for broader coverage in large spaces. Each Sensor may be added to up to 10 receiving devices. Sensor Operation Occupancy Version The Sensor will automatically turn the lights on when the space is occupied and automatically turn the lights off after the space is vacated. Vacancy-Only Version The lights must be manually turned on* at the dimming or switching device. The Sensor will automatically turn the lights off after the space is vacated.
* 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: For either Sensor version, the lights can also be manually turned off at any time by using the dimming or switching device directly. 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 Sensor. 5. 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 6. Use only high-quality lithium batteries, size CR123, 3 V IEC-CR17345). DO NOT use rechargeable batteries. Using improperly rated batteries could damage the Sensor.

A Install a Sensor in as little as 15 minutes Instructions A 1 2 Pre-Installation Before setting up the Sensor, the corresponding dimming or switching device(s) should be installed. Refer to that products installation sheet for instructions. Twist and remove mounting bracket to insert battery. Battery Release Tab B Set-Up In order for the Sensor to operate properly, it must first be set up with a corresponding dimming or switching device. The procedure for setting up a Sensor with a Maestro Wireless (MRF2- only) Dimmer or Electronic Switch is detailed below. 1.3 1.4 1.5 2 Perform the Sensor coverage and wireless communication tests as described in sections E. Testing Sensor Coverage and F. Testing Wireless Communication. If the Sensor does not perform satisfactorily from this location, it may be moved to another location by pulling the Sensor straight down and repeating steps 1.3 and 1.4. If the Sensors performance is satisfactory, it should be permanently attached to the ceiling tile, as described in section G. Permanent Mounting. Temporary Solid Ceiling Mounting Use this procedure if the Sensor will be mounted on a solid, continuous ceiling surface such as drywall, plaster, concrete, or wood. Two 3M Command adhesive strips are provided for temporarily mounting and testing the Sensor on smooth, solid ceiling surfaces. These strips are designed for easy, damage-
free removal and are not reusable. These strips should not be used for permanently mounting the Sensor (see section G. Permanent Mounting ). Carefully follow the removal instructions below to ensure the ceiling is not damaged during removal. NOTE: DO NOT use the adhesive strips on ceiling tiles, as they will likely cause damage to the tile upon removal. 2.1 Peel the red Command Strips liner off of one of the adhesive strips and apply the strip to the flat side of the mounting bracket as shown in the diagram. Press firmly. If setting up a Sensor with a different device, visit www.lutron.com/occsensors or consult the installation guide for that device for the correct set-up procedure. Setting up a Sensor with a Maestro Wireless Dimmer or Electronic Switch Place the Dimmer or Switch in set-up mode by pressing and holding the tap button for approximately 6 seconds until all LEDs on the device begin flashing. Release the tap button. Add the Sensor to the Dimmer or Switch by pressing and holding the Lights Off button on the front of the Sensor for approximately 6 seconds until the lens flashes briefly. The lights in the room will also flash 3 times, indicating the Sensor has been successfully added. The Dimmer or Switch will exit set-up mode automatically. Dimmer or Switch 2.2 2.3 2.4 NOTE: DO NOT cover the brackets screw holes because they will be used to mark screw hole locations on the ceiling. NOTE: Leave the removal tab exposed past the edge of the bracket so it can be accessed for removal later. Identify a location on the ceiling where the Sensor will have a good view of the room. Remove the black wall side liner from the adhesive strip. 2.4 Attach the Sensor to the mounting bracket by inserting and twisting in a clockwise direction until the Sensor locks into place. Position the mounting bracket on the ceiling and press firmly for several seconds. The Lights On and Lights Off buttons should now switch the lights in the room on and off, respectively, when pressed. Repeat the above procedure to set up the Sensor with any additional devices. Setting the Occupancy Light Level (occupancy version, dimming devices only) Set the Dimmer to the desired light level for entering the room. Save the occupancy light level by pressing and holding the Lights On button on the front of a Sensor that has been set up. After approximately 6 seconds, the lens will flash rapidly several times, indicating the light level has been saved. All Sensors set up with the Dimmer will now use the saved occupancy light level. Attach the Sensor to the mounting bracket by inserting and twisting in a clockwise direction until the Sensor locks into place. Perform the Sensor coverage and wireless communication tests as described in sections E. Testing Sensor Coverage and F. Testing Wireless Communication. 2.5 2.6 Removing Temporary Mounting Strip 2.7 Remove the Sensor from the mounting bracket by twisting in a counter-clockwise direction. If the Sensor coverage and wireless communication tests have been successfully completed, use the mounting bracket as a template to mark the screw hole locations with a pencil. C Sensor Placement and Coverage Before mounting the Sensor, please note the following:
The Sensor is designed for ceiling use only. DO NOT install on ceilings higher than 12 ft (3.7 m) or non-ceiling surfaces. Doing so may significantly inhibit the Sensors performance. 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 the Sensor, 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 or light bulbs installed below the ceiling line. Warmer rooms may reduce the Sensors ability to detect occupants. 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 the intended space. If this is unavoidable, the lens can be masked to block the view of undesired areas (refer to section I. Lens Masking). The Sensors detection range is dependent on the ceiling height, as shown in the table below. Sensor Coverage Chart Ceiling Height 8 ft (2.4 m) Max. Room Dimensions for Complete Coverage 18 x 18 ft (5.5 x 5.5 m) Radius of Coverage at Floor 13 ft (4.0 m) 9 ft (2.7 m) 20 x 20 ft (6.1 x 6.1 m) 10 ft (3.0 m) 22 x 22 ft (6.7 x 6.7 m) 12 ft (3.7 m) 26 x 26 ft (7.9 x 7.9 m) 14.5 ft (4.4 m) 16 ft (4.9 m) 19 ft (5.8 m) D 1 Temporary Mounting Methods If you are uncertain about correctly positioning the Sensor, the following temporary mounting and testing procedures are recommended to verify proper performance before permanently installing the Sensor. Temporary Drop Ceiling Mounting Use this procedure if the Sensor will be mounted on a ceiling tile. The ceiling tile mounting wire is provided for both temporary and permanent mounting of the Sensor to drop ceilings composed of multiple tiles. It is designed to allow temporary mounting, testing, and repositioning (if necessary) of the Sensor without damaging a ceiling tile. Once the Sensors final position has been chosen, the mounting wire can be twisted to lock the Sensor in place permanently. 1.1 Insert the ceiling tile mounting wire through the two smaller holes in the mounting bracket and replace the mounting bracket. 1.2 Mount Sensor to a ceiling tile by inserting the wire legs through the tile, making sure the Sensor is flush to the tile. Note: Do not twist wire legs together. 2.8 To remove the bracket from the ceiling, grasp the removal tab on the adhesive strip and pull the tab VERY SLOWLY straight across the ceiling, stretching the strip until the bracket releases from the ceiling. Discard the strip. NEVER pull the strip at an angle, as it may break or damage the ceiling surface. NOTE: Pull very slowly. NOTE: Do not pull at an angle. E Testing Sensor Coverage 1 With the Sensor mounted on the ceiling, press and release the Test: Sensor button on the front of the device. The lens will glow briefly, indicating the test mode has been entered. NOTE: There is a warm-up period of approximately 40 seconds after the batteries are installed before the test mode can be 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. 2 3 4 5 F 1 2 3 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: Sensor 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 retested. If the Sensor still has poor detection from the new location, refer to the Troubleshooting section. NOTE: If the Sensor is detecting motion in areas that are not desirable, such as hallways or adjacent rooms, refer to section I. Lens Masking. If Sensor detection is satisfactory during this test, perform the wireless communication test as described in section F. Testing Wireless Communication. 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. If the lights in the room are not on, turn them ON manually at the dimming or switching device. Press and release the Lights Off button on the front of the Sensor. The lights should turn OFF. Press and release the Lights On button on the front of the Sensor. The lights should turn ON. If the lights do not respond correctly, refer to the Troubleshooting section. G 1 1.1 1.2 1.3 2 2.1 2.2 2.3 Permanent Mounting Methods Permanent Drop Ceiling Mounting After the Sensor has been temporarily mounted, leave the Sensor in place on the tile and either take the tile down or remove an adjacent tile to gain access to the legs of the mounting wire on the back of the tile. Twist the wire legs together tightly so the mounting bracket remains snug against the tile. Replace the tile. Permanent 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. NOTE: Do not over-tighten. H Advanced Set-Up (Optional) 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 Sensitivity. The Vacancy-Only version has only two modes
(Auto-On not available). The default settings are listed below. Default Settings:
Timeout 30 min 15 min 5 min Auto-On Always Low light Disable Activity Timeout 30 min 15 min 5 min Timeout: 15 minutes Auto-On: Always (Occupancy version only) Activity:
Low Activity Activity Auto-On Always Low light Disable P Advanced Set-Up Modes U L L Timeout P U L L P U L L P U L L The Sensor will turn the lights off if no motion occurs for the duration of the timeout period. There are three available timeout settings: 5, 15, and 30 minutes. 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: Always, Low light, and Disable. Always: 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. Disable: 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. NOTE: The 15-second vacancy grace period is active in this mode. Refer to the Sensor Operation section at the beginning of this document for more details. 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.
* 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. Advanced Set-Up Operation The advanced set-up is accessed by using the buttons on the back of the Sensor. 1 2 3 4 5 To display the current setting, press and release the desired button. An LED will illuminate briefly, indicating the current setting. To adjust a setting, press and hold the desired button until the LED corresponding to the current setting begins flashing rapidly, indicating the setting can now be adjusted. Each subsequent button press of less than 2 seconds will increment the mode to the next available setting. Pressing any of the other buttons will have no effect. To save the selected setting, press and hold the button until the LED turns on solid, indicating the saved setting. During the adjustment procedure, if there is no activity for 30 seconds, the LEDs will turn off and no settings will be saved. I Lens Masking (Optional) Whenever possible, the Sensor should be installed in a location where it cannot easily see into areas outside the intended space, such as hallways or adjacent rooms. If this situation cannot be avoided, portions of the lens may be masked with the provided labels to block the Sensors view of the undesired areas. It is recommended to remove the Sensor from the mounting bracket before applying the masking labels. NOTE: The Sensor can be screwed onto the mounting bracket in several different orientations. Be sure to note the Sensors orientation before taking it down and replace the Sensor in the same orientation to ensure the intended area gets blocked. Outer lens sections correspond to the detection regions furthest away from the Sensor, while inner sections correspond to regions closer to the Sensor. Be careful when applying the labels to avoid creating gaps between adjacent masked sections. The Sensor may detect motion through inadvertent gaps. Lens sections shown in white are masked with labels Lens Mask Lens sections shown in gray have not been masked Hallway falls within Sensors coverage area. Troubleshooting Symptom Lights do not turn ON when space is occupied. Lights turn OFF while space is occupied. Lights stay ON after space is vacated. Lights turn ON when walking past room.
