The 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 Maestro sensor family, including: adaptive relay switching, smart ambient light detection, and simple button presses for changing settings. The Maestro 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”. FEATURES: XCTT Technology for major, minor, fine, and very fine motion detection180° sensor field-of-viewTamper-resistant PIR lensUp to 900 ft2 (81 m2) major motion coverage and 400 ft2 (36 m2) minor motion coverageTwo Ambient Light Detect (ALD) options:Learning ALD Mode:Uses adaptive algorithm.Sensor learns user’s preferred light level over time.Fixed ALD mode:Four selectable light level thresholds: Hi, Med, Low, MinOccupancy models (MS-A102-XX, MS-B102-XX, MS-A202-XX, MS-B202-XX) can be set to Auto-ON / Auto-OFF or Manual-ON / Auto-OFF per circuitDual-circuit models (MS-A202, MS-B202) meet Title 24 requirements for multi-level lighting control.Single-circuit “Vacancy” models (MS-A102-V-XX, MS-B102-V-XX) available to meet Title 24 / Title 20 requirements for vacancy sensors.Adjustable timeout for each circuit (1, 5, 15, or 30 minutes)Sensitivity adjustmentPIR (Hi, Med, Low, Min)Ultrasonic (Hi, Med, Low, Off)Switches all lighting loads: incandescent, halogen, ELV, MLV, CFL, LED, magnetic fluorescent, electronic fluorescentSwitches fan loads at 120 V~ MS-B102, MS-B102-V work with MaestroR accessory switches in multi-location applicationsMS-A models DO NOT require neutral wiring, while the MS-B models DO require neutral wiring.
