• Designed to shunt around a lighting control panel during an emergency power loss.• Bypasses local switch or a lighting panel from controlling the load.• Mounts in an enclosure or the lighting fixture• Meets UL 924 requirements

This Emergency Shunt Relay is designed for an application where designated emergency lightsare ON/OFF controlled by a lighting control panel during non-emergency times. When a poweroutage occurs, the UL 1008 Transfer Switch transfers power from the Normal power to theEmergency power source. At the same time the RRU-1 unit senses the outage and bypassesall ON/OFF control from the switch or the control panel to meet UL 924 requirements.
