Emergency Lighting Control Unit Wiring Diagram

About this detail

Wiring connections for a Wattstopper ELCU-200 emergency lighting control unit, or approved equivalent, complying with UL standard 924 and UL standard 916. The unit receives power inputs from both normal and emergency lighting panels along with neutral and sense conductors from normal switches or occupancy sensors. Switched sense outputs connect to normal fixtures while power output feeds emergency fixtures directly from the emergency power source. The schematic provides wire color coding including black for power in and normal sense, white for neutrals, and red for power out and switched sense lines.
