The Automatic Load Control Relay (ALCR) is a UL 924 listed emergency device that is powered from an always-available normal / emergency source fed by an upstream emergency transfer switch. The ALCR provides power to emergency lighting load(s) by bypassing switches or other controls upon loss of utility power and ensuring a "lights-on state" during loss of normal power while tracking the state of normal lighting loads during normal operation.
