Diagram Descriptions: The document includes various diagrams illustrating fixture dimensions, mounting configurations, and wiring. These diagrams show details for different options such as MVOLT UGZ, DALI, QDS, and CP. Specific diagrams detail the LBR6PFWCP, LBR6 SWW1 ALOx MVOLT UGZ CP, LBR6 ALOx SWW1 xx xxx 347 UGZ, and LBRx nLIGHT configurations, providing measurements and connection points for different electrical and control system integrations. For example, one diagram shows the LBR6 SWW1 ALOx MVOLT UGZ CP with dimensions for the fixture, driver, and conduit connections. Another illustrates the LBRx nLIGHT setup with CAT-5e cabling and control components like nPS 80 EZ and nCM ADCX.

Photometry

Photometric data is provided for specific configurations, including distribution curves, zonal lumen summaries, and luminance data.

Example Photometry:

• LBR6 SWW1 ALO2 AR LSS MWD MVOLT UGZ: Input Watts: 18.1, Delivered Lumens: 1970, LPW: 108.8, S/MH: 0.94, Test No: 20-518-03. Includes distribution curve, zonal lumen summary, luminance data, beam angle (61.5°), and field angle (92.7°).

Lumen Output Multipliers

How to Estimate Delivered Lumens in Emergency Mode:

Use the formula: Delivered Lumens = 1.25 x P x LPW, where P is the output power of the emergency driver (e.g., 10W for PS1055CP) and LPW is the lumen per watt rating of the luminaire.

Dimmer Compatibility

The LBR6 is not compatible with DALI or DMX dimmers. Compatibility with various dimming systems is detailed below.

Control Systems & Additional Data

JOT (Just One Touch)

The Sensor Switch JOT enabled solution offers a wireless, app-free approach to single room lighting control using Bluetooth® Low Energy (BLE) technology for wireless dimming and switching.

Diagram: Illustrates the JOT system setup:

1. Install: Install JOT enabled fixtures and controls as instructed.
2. Pair: Insert the pairing tool into the pinhole on the wall switch; press and hold any button for 6 seconds.
3. Play: Once paired, each fixture will individually dim down to 10% brightness. All products will be fully functional.
