UL924 Emergency Lighting Relays

Our ESRN and ESRLBC UL924 Emergency Lighting Relays can be used for automatic load control relay (ALCR) or bypass/shunt applications to turn on emergency lighting in the event of the loss of normal utility power. In ALCR applications, when normal power is present, the ESR relay coil is activated and the emergency panel is fed from normal power. The lighting load can be switched on/off using an individual wall switch. When normal power drops out, the ESR coil is deactivated and N/C contact falls closed. The automatic transfer switch changes over to backup (generator) power, and the lighting load is illuminated regardless of the position of the wall switch or controller scheme.
