Emergency lighting controls

The UL924 emergency lighting control relay (ERC) mounts in the ceiling and features an automatic diagnostic feature to replace the need for an accessible test switch. When lighting is turned off in a room, the emergency luminaires stay on for an additional 2.5 sec to verify the emergency power source and that lighting is functioning correctly. The UL924 emergency lighting dimmer control (EDC) turns lights on to full brightness in an emergency. The EDC is available in 120V and 277V models and includes a test switch. The UL924 emergency lighting control relay (panel-mount) (EPMC) is a universally compatible device available in 120V and 277V models. The test switch allows user to test their emergency lighting system with the press of a button, and a green LED confirms wiring connections and power availability.
