Additional Data: JOT System

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

Simple Setup (1, 2, 3):

1. Install JOT enabled fixtures and controls.
2. Pair the wireless battery-powered wall switch by inserting the pairing tool and holding any button for 6 seconds.
3. Fixtures will dim to 10% brightness, indicating successful pairing.

Diagram Description: Illustrates a typical group fixture control setup with nLight controls, including a dual on/off/dim wall station, daylight harvesting sensor, and occupancy sensor.

nLight® AIR Controls

nLight AIR is ideal for retrofit or new construction where communication is cost-prohibitive. The integrated nLight AIR rPP20 Power Pack is part of each Lithonia LDN Luminaire.

UL924 Sequence of Operation (for EM options): EM devices remain at high-end trim and ignore wireless commands unless a normal-power-sensed (NPS) broadcast is received. Association with a group including an NPS device is required via the CLAIRITY+ app.

nLight AIR Accessories:

• Wall Switches: rPODB [color] (single pole), rPODB 2P [color] (two pole), rPODB DX [color] (single pole raise/lower), rPODB 2P DX [color] (two pole raise/lower), rPODBZ DX WH¹ (single pole raise/lower, requires RES7Z sensor).

Diagram Description: Shows the simple 1, 2, 3 setup for nLight AIR: Install fixtures, install wireless switch, pair with CLAIRITY app.
