What is a FASS?

All Lutron dimmers have an air-gap off. Typically this is integrated into a slider or paddle switch. Some dimmers have electronics that stay active when the lights are off, such as an infrared receiver. For these products, the air gap is activated by a separate Front Accessible Service Switch (FASS). When open, the FASS completely disconnects the power to the load. This ensures that there is no leakage current to the fixture during routine lamp maintenance. In addition, when the FASS is open, no remote locations (3-way, etc.) can re-energize the circuit.
