Emergency Battery Pack Options - Field Installable

*Minimum delivered lumen output to assist in product selection for increased fixture mounting height.

Photometry

Photometric data is provided, including distribution curves, zonal lumen summaries, cone of light data, and luminance data for various configurations. Lumen output multipliers are available for different CCTs, finishes, and CRI values. A guide is included for estimating delivered lumens in emergency mode using the formula: Delivered Lumens = 1.25 x P x LPW.

Detailed compatibility charts are provided in the original document.

Lighting Control Systems

JOT (Just One Touch)

A wireless, app-free system using Bluetooth Low Energy (BLE) for dimming and switching. Setup involves installing fixtures and controls, pairing via a pinhole tool, and then the system operates.

nLight Wired Controls

Offers various wall control styles (Push-Button, Graphic) and accessories like occupancy sensors, photocells, and dimming modules. Example wiring diagrams demonstrate integration with sensors for manual and automatic control, including daylight harvesting and occupancy sensing.

nLight AIR

An integrated wireless solution for retrofit or new construction spaces, featuring smart sensors and individually addressable controls. Setup involves installing nLight AIR fixtures, wireless wall switches, and pairing via the CLAIRITY+ mobile app for customization.

UL924 Sequence of Operation: For nLight AIR devices with an EM option, emergency operation maintains high-end trim unless a normal-power-sensed (NPS) broadcast is received. Association with a group including a normal power sensing device is required for EM devices to receive NPS broadcasts.
