Automatic Load Control Relay

A simple and smart energy solution for emergency lighting systems

In a time of energy consciousness, ETC's Automatic Load Control Relay (ALCR) offers a simple and smart way to reduce overhead energy costs.  

The ALCR is a UL924 emergency lighting device that allows a single light, or zone of emergency lights, that are typically always on, to be controlled under everyday non-emergency circumstances, while forcing emergency lights on when normal power is lost or a fire alarm is activated. For increased safety and visibility, after a state of emergency is over and normal lighting is recovered, an optional delay (between 0-15 minutes) can be programmed to hold the emergency lighting state prior to returning to normal control as people exit or enter through normally dark areas.   

Automatic Load Control Relay

The ALCR is available in two models: Power Pack (ALCR-PP) and DIN (ALCR-DIN). The DIN model functions the same as the PP model and is designed specifically for 0-10V fixtures and ballasts.
