The Lutron LRF2-DCRB Radio Powr Savr Daylight Sensor is designed for use with compatible Lutron products. A key feature of this sensor, and several other Lutron ceiling and wall-mounted devices, is the ability to utilize a green laser for programming and access to features from floor level, eliminating the need for a ladder during setup and maintenance. The sensor’s model number can be found on packaging or on a label affixed to the device itself. This article details the specifications for green laser usage, association procedures, and locating the model number for the LRF2-DCRB.
Identifying the LRF2-DCRB Model Number
Locating the model number of the LRF2-DCRB is essential for accessing support documentation and ensuring compatibility. According to the provided documentation, the model number is typically found in one of two locations. If the original packaging is available, the model number is printed on the insert card within plastic packaging or on the top of the box. The model number is characterized as being 12-16 characters long and beginning with a combination of letters followed by a dash.
If the original packaging is unavailable, the model number is located on a label affixed to the side of the device. In cases where the device is already installed, it is necessary to turn off the power, remove the wallplate, and unscrew the device to access the label. It is noted that the product number location differs for Ariadni/Toggler dimmers, which display the number directly on the front of the device, either on the top left or below the on/off toggle.
Green Laser Specifications for Programming
Several Lutron devices, including the LRF2-DCRB, can be programmed using a green laser. Specific specifications for the laser are outlined to ensure proper functionality. The laser must have a constant wave output with a wavelength of 532 nM and a maximum output power of 5 mW. These specifications are critical for the laser to be recognized by the sensor during the association process.
Associating the Sensor with Lutron Products Using a Laser
The standard installation guide for the LRF2-DCRB is modified when utilizing a green laser for association with compatible Lutron products. The typical procedure involves pressing and holding the “Link” button on the sensor for approximately six seconds. However, when using a laser, this step is skipped. Instead, the process is initiated by turning on the laser and passing the beam over the hole in the sensor.
The sensor will respond by flashing its lens LED rapidly, then transitioning to a blink rate of once per second. This indicates that the sensor is ready to receive the association command. To initiate the command, the laser beam must be passed over the sensor hole again within a 10-second window. Upon successful initiation, the sensor’s lens LED will flash rapidly again. The documentation directs users to refer to the specific product documentation for the expected response upon completion of the association process. If the laser beam is not passed over the sensor hole within the 10-second window, the sensor will revert to normal operation.
Calibration Mode and Laser Programming
Following the association process, the LRF2-DCRB automatically enters Calibration Mode. Calibration is necessary to ensure the sensor accurately interacts with the base unit(s). The calibration procedure itself is detailed in the product documentation accompanying the base unit. The sensor will automatically exit Calibration Mode if left unattended for 10 seconds.
Compatibility with Other Lutron Devices
The documentation lists several other Lutron devices compatible with green laser programming, including:
- Radio Powr SavrT Occupancy/Vacancy Ceiling Sensor (model LRFX-OCR2B-P, LRFX-OCRB-P)
- Radio Powr SavrT Vacancy Ceiling Sensor (model LRF2-VCR2B-P)
- Radio Powr SavrT Occupancy/Vacancy Wall Sensor (model LRFX-OWLB-P, LRFX-OHLB-P, LRFX-OKLB-P)
- Radio Powr SavrT Vacancy Wall Sensor (model LRF2-VWLB-P, LRF2-VHLB-P, LRF2-VKLB-P)
The provided documentation does not detail the specific programming procedures for these other devices, only confirming their compatibility with the green laser method.
