Product Overview The Leviton ACS20-DMW is a ceiling-mounted occupancy sensor with an integrated relay for single-zone lighting control. It operates on 120–277 VAC and combines passive infrared (PIR) and ultrasonic sensing to detect occupancy and directly switch lighting loads. Bluetooth connectivity enables wireless configuration and commissioning via the Leviton Smart Sensor App. Key Features & Design Functionality: Ceiling-mounted occupancy sensor with an integrated relay for single-zone lighting control Installation context: Designed for ceiling mounting in standard junction boxes; line-voltage operation eliminates the need for external power packs Notable specifications: 120–277 VAC input, up to 2000 sq ft coverage, 360° detection pattern, integrated relay switching up to 8 A depending on voltage, Bluetooth configuration, ambient light sensing with AutoCal Contractor-relevant details: Supports wireless commissioning via mobile app, allows linking of multiple sensors for expanded coverage, compatible with standard commercial wiring practices Performance / Benefits Dual-technology sensing combines PIR for initial motion detection with ultrasonic monitoring for sustained occupancy, enhancing reliability in varied spaces. The integrated relay enables direct load control, simplifying installation by reducing additional devices. Built-in daylight sensing with AutoCal minimizes unnecessary lighting operation, while Bluetooth configuration enables efficient on-site setup and adjustments.
