The document summarizes the System Sensor A77-AB Adapter Bracket, which allows installers to retrofit applications where a larger diameter smoke detector was previously installed. The adapter bracket is made of high UV-resistant plastic, comes in a 6.5-inch diameter to fit 100 and 400 series detectors, and does not require additional hardware. It covers the footprint of old detectors to allow new detectors to blend into acoustic ceilings without costly repainting.
