Product Description

The IOTA ETS-STEP Emergency Lighting Control Device allows the use of local switch and step dimming control on designated emergency luminaires when emergency power is provided by a generator or inverter. The ETS-STEP senses the loss of normal AC power and bypasses local step dimming settings, allowing emergency power directly to the fixture regardless of bi-level control settings. The ETS-STEP is rated for any lamp load up to 3 amps continuous power including LED loads per NEMA 410 standards. The ETS-STEP 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. The additional power lead of the ETS-STEP interfaces with the driver or ballast’s step dimming control for proper emergency operation of the fixture from the designated auxiliary supply.
