OVERVIEW

The nLight AIR rCMSB  is a wireless ceiling/surface mount occupancy and daylight sensor family that utilizes digital Passive Infrared (PIR) and photocell detection with adjustable time delays for dimming and on/off switching of luminaires. It is battery-powered for simple installation into a variety of ceiling types. When installed as part of a nLight AIR lighting control system, the rCMSB will send commands to other devices wirelessly for networked control strategies.

INSTALLATION INSTRUCTIONS

INSTALLATION STEPS
There are 3 mounting options with the rCMSB: Surface, recessed, and junction box mounts. Please see the installation steps for each option. Once the mounting plate is installed, proceed to the sensor installation process to complete the installation. Do not mount using adhesive tape.

SURFACE MOUNT INSTALLATION

1. Disconnect the sensor from the mounting plate by twisting the top half of the sensor counterclockwise. This will unlock the sensor from the mounting plate.
2. Place the mounting plate at the sensor location and mark the two holes to drill. Drill 3/16” hole through ceiling surface at these locations. Note: If using an aisleway lens (45A), be sure to align the mounting plate with the arrows as indicated on the mounting plate.
3. Insert anchors (#6-8-10 X 1”) into ceiling surface at drilled locations.
4. Mount the mounting plate to the anchors using the screws (#6 Pan-Head Phil/Slot 1”) provided.

RECESSED MOUNT INSTALLATION

1. Disconnect the sensor from the recessed mounting plate by twisting the top half of the sensor counterclockwise. This will unlock the sensor from the mounting plate.
2. Drill a hole using a 3” hole saw in the surface you plan to mount the sensor. Hole size should not exceed 3.25” to ensure proper fit.
3. Pull the spring clips up on the plate and guide them through the ceiling hole. Once inside the hole, the spring clips will pull the plate up, covering the hole drilled.

JUNCTION BOX MOUNT INSTALLATION

1. Disconnect the sensor from the junction box mounting plate by twisting the top half of the sensor counterclockwise. This will unlock the sensor from the mounting plate.
2. Align the mounting plate to the junction box with the holes matching where the screws will attach to the junction box. Note: If using an aisleway lens (45A), be sure to align the mounting plate with the arrows as indicated on the mounting plate.
3. Mount the mounting plate to the junction box using screws for the junction box (typical #6 Pan-Head Phil/Slot 1”).
4. Attach the optional mounting ring by inserting the tabs into the corresponding holes on the mounting plate. Note: If you need to remove the mounting ring, there are small arrows along the ring to indicate where the tabs are located. Place a flathead screwdriver at one of these locations between the ring and the mounting plate and gently pry upwards to remove.

SENSOR INSTALLATION

1. Remove the pull tab from the battery compartment on the bottom of the sensor. Verify the sensor is operational by tapping once on the button next to the sensor lens. A green LED will light up as you tap the button.
2. Place the sensor in the mounting plate and rotate clockwise until the sensor seats into the plate (for the recessed mount, you may need to pull down on the mounting plate slightly or remove it altogether to install the sensor). Continue to turn until it is locked in place – you feel/hear a slight click. Ensure the sensor is seated completely around the entire edge, as there are two locking tabs on the unit.
3. Proceed next to commissioning using the Clarity Pro app.

NOTE
You will need to push the button on the sensor during the commissioning process.
NOTE
If you need to remove the surface mount sensor for any reason, simply twist counterclockwise to remove it. If you need to remove the recessed mount sensor, pull down on the sensor until one of the ceiling clips is exposed and you can grab it with your fingers. Guide this first clip out of the hole, then remove the entire unit. At this point, you can now twist counterclockwise to remove the sensor from the mount.

REQUIRED TOOLS & SUPPLIES

• Drill (Surface Mount)
• Screwdriver (Surface Mount, Junction Box Mount)
• 3” Hole Saw (Recessed Mount)

COMMISSIONING PROCESS

All nLight AIR devices utilize the Clarity Pro mobile app for commissioning. Refer to the quick start guide for a brief introduction to the commissioning process. It is recommended that you follow the commissioning process with the device installed in its final location. This will ensure you have a proper network connection.

1. The rCMSB conserves the battery prior to commissioning. In order to activate it during commissioning, simply double-tap the button on the device next to the lens. This will allow you to see and identify the device in Clarity Pro.

2. After tapping the button twice, the device will display in Clarity Pro for 1 minute, at which time you should select the device and add it to your grid.
   NOTE
   At least 1 line-powered device must be added to the grid first before adding any battery-powered devices

3. .Once the device is on the grid, you will now have an additional 2 hours where the device will remain active in commissioning mode. You can visibly see this with a simple 1-sec blink pattern on the device.

4. Proceed to add other devices in the space to the grid.

5. Once you have completed adding all devices to the grid, you can now proceed to set up your behavior zones. Refer to the quick start guide or user guide for more information on this process.

6. Once your behavior zones are set, tap Save and this will complete the commissioning process. If you were not able to complete this process within the 2-hour window, upon tapping Save, Clarity Pro will instruct you to wake devices via motion sensor by walking under each sensor. If a sensor does not wake up, simply double-tap the button again next to the sensor lens.
   NOTE
   The blinking of the LED to indicate active commissioning mode can be silenced with a simple single tap of the button. After saving behaviors, there is a 2-minute sync process before rCMSB controlled devices will respond to occupancy delay times. This sync process occurs after the space has become unoccupied.
   If a firmware update is required for the rCMSB, you must update each device individually from the Site Overview screen.

Test Mode
The rCMSB has a test mode feature for verifying occupancy and daylighting with the output devices. Once placed in test mode, the occupancy time out will occur within approximately 30 seconds to the dim percentage as programmed in Clarity Pro and by simply shining a light on the photosensor, the outputs will change from 100% (or max level) to 1% (or min level) in approximately 15 seconds.
To enable test mode, press the button next to the sensor lens 3 times, wait for the LED to blink twice (indicates test mode disabled), and then press the button once. Confirmation of successfully entering test mode will be seen with three subsequent LED blinks with a 1-second pause between each. This will enable test mode for 10 minutes. To disable, press the button 3 times, followed by pressing it 2 times. Otherwise, the test mode will expire on its own after 10 minutes, at which point it will return to the programmed settings put in Clarity Pro.

Low Battery Mode
When the rCMSB has reached a very low battery threshold, the device will go to sleep and produce the following blink code at the LED on the unit:

• LED on for 1/4 sec
• LED off for 10 sec
• Repeat

PUSH-BUTTON SETTINGS

Please read all 3 steps before using the push button functions

1. Enter a function by pressing a button the number of times as the desired function number from the tables below (e.g., press three times for function 3, test mode).
2. LED will flashback the selected function’s current setting (e.g., 2 flashes for disabled). To change the setting, proceed to step 3 before the flash-back sequence repeats 3 times. To exit the current function or to change to a different function, wait for the sequence to repeat 3 times then return to step 1.
3. Press the button the number of times indicated in the particular function’s detailed table for the NEW desired setting (e.g., press 1 time for enabled). As confirmation of setting change, LED flashes back the NEW setting 3 times before exiting.
