The ELCU-100 Emergency Lighting Control Unit allows lighting control devices for normal lighting to also control emergency lighting
installed within the area. The ELCU is designed for lighting control in areas where emergency lighting fixtures are connected on
dedicated emergency lighting circuits that are typically ON 24 hours per day. The ELCU allows ON/OFF control of the emergency
lighting along with the normal room lighting to save energy.
The intended operation of the ELCU is to guarantee that the emergency lighting is ON whenever normal power to the controlled circuit
is interrupted. While normal power is present, the ELCU allows control of the emergency lighting by a device such as an occupancy
sensor, a relay, a dimmer, or a wall switch.
