Maestro dual technology (dual Tech) occupancy sensor switch applies our exclusive XCTT Technology to the ultrasonic as well as the passive infrared technology in this sensor to create a product that can detect very fine motion, such as typing. This product also includes all of the great features found in the rest of the MaestroR sensor family, including: adaptive relay switching, smart ambient light detection, and simple button presses for changing settings. The MaestroR Dual Tech Occupancy Sensor Switch is available in single-circuit and dual-circuit versions. The single-circuit versions (MS-A102, MS-B102) can be used to meet many of the Title 20/24, ASHRAE 90.1, and IECC code requirements such as “automatic shutoff”. The dual-circuit versions (MS-A202, MS-B202) can be used to meet many of the Title 20/24, ASHRAE 90.1, and IECC code requirements such as “automatic shutoff” and “multi-level lighting control”.
