Lighting Control Wiring Diagram

About this detail

Interconnections between a twenty-four volt direct current wall occupancy sensor and momentary switch, a power pack, and an emergency lighting control unit (Wattstopper ELCU-200). The twenty-four volt direct current wall occupancy sensor connects via three low-voltage lines to the power pack. The power pack interfaces with normal line and normal neutral conductors from the normal circuit, while providing normal switched sense, normal neutral, and normal power sense connections. The emergency lighting control unit integrates emergency line, emergency neutral, normal switched sense, normal neutral, and normal power sense feeds, with a jumper loop to remain intact. A drawing note mandates that the power pack and emergency lighting control unit shall be mounted in the nearest accessible location.
