The IOTA ETS-DR Emergency Lighting Control Device allows local switch control of designated emergency luminaires when emergency power is provided by a generator or inverter. The ETS-DR senses the loss of normal AC power and bypasses the local switch device allowing emergency power directly to the fixture regardless of switch position. The ETS-DR is rated for any lamp load up to 3 amps continuous power including LED loads per NEMA 410 standards. The ETS-DR is an ideal solution for achieving increased energy savings in accordance with most energy efficiency standards by eliminating the need to operate the designated emergency fixtures 24/7 when emergency power is sourced from a generator or inverter.
