ATSD

DESCRIPTION

Application
The auxiliary transfer switch works in conjunction with an emergency lighting inverter or auxiliary generator to power switched or dimmed emergency lighting fixtures. The auxiliary transfer switch senses the loss or normal power and, bypassing the switch or dimmer, transfers the lighting load to a designated emergency power source, regardless of the switch or dimmer position.
