Series Description
The Functional Devices ESR Series UL924 emergency lighting shunt relays, or bypass relays, are designed for applications that require an emergency load, such as exit lighting or any other emergency lighting, to be switched on during a loss of normal power. The economically priced relays are available prepackaged in their own Nema 1 enclosure or in panel versions to be installed inside an existing enclosure. Emergency lighting relays can be ordered with a standard two-position on/auto override switch.The override switch models can be used for testing purposes to verify your emergency load is being switched properly.
