Overview
The Automatic Load Control Relay (ALCR) is a UL 924 listed device that is powered
from an emergency source and provides power to emergency lighting load(s). The
ALCR ensures a “lights on state” during loss of normal power while tracking the state of
normal lighting loads during normal operation. The ALCR also assures a “lights on”
override by utilizing a normally closed emergency contact closure which interfaces with
fire alarm and emergency systems.
The ALCR is available in two models for installation convenience including Power Pack
(ALCR-PP) and DIN-rail (ALCR-DIN).
