The ATSD auxiliary transfer switch works in conjunction with an emergency lighting inverter or an auxiliary generator to power switched or dimmed emergency lighting fixtures up to 3A. The auxiliary transfer senses the loss of normal power and bypasses the switch or dimmer, transferring the lighting load to a designated emergency power source, regardless of the switch or dimmer position. Recommended applications include: auditoriums, classrooms, or any other location with generator or inverter-supplied emergency lighting.

The ATSD consists of relay switching circuitry and fusing in one compact galvanized steel case. The auxiliary transfer switch device is suitable for use indoor-dry or damp location fixture.

The ATSD auxiliary transfer device does not affect normal fixture operation and comes fully assembled to mount in the fixture ballast channel. In addition to available wiring, the device requires a direct, unswitched connection to a generator or inverter-supplied emergency panel and an unswitched source on the same branch circuit as the switched supply. One auxiliary transfer switch device per fixture can be used to bypass fixture wall switch allowing the building generator to bring on switchable fixture and not just those on “night-light” circuits. (See diagram on second page of PDF Specification)
