The GTD generator transfer device introduces a new way to save energy and provide Code-compliant fluorescent emergency lighting. The device works in conjunction with an auxiliary generator to power fluorescent emergency lighting fixtures regardless of fixture wall switch position. The device senses the loss of normal power, bypasses the wall switch and supplies generator power directly to the AC ballast. The device provides reliable emergency lighting only when it’s needed. It’s suitable for use in indoor dry and damp locations and comes with a five-year full warranty. The Bodine Co. Inc.
