Control Unit Wiring Diagram

About this detail

Wiring connections for an ELCU-200 emergency lighting control unit connected to a lighting control panel. The unit receives normal power unswitched hot 120/277 volts along with a normal power sense black 18 AWG wire, a normal neutral white 18 AWG wire, and a normal switched sense red 18 AWG wire. Emergency power in uses a black 12 AWG wire, emergency neutral uses a white 12 AWG wire, and emergency power out uses a red 12 AWG wire to feed exterior lighting requiring a 0-10VDC dimming ballast. A jumper loop can be cut for use with normally closed test switches, fire alarm panels, security panels, or other remote activation devices. Upon the loss of normal power, the UL924 listed ELCU-200 bypasses the lighting control panel and forces the emergency fixtures ON.
