SensorWorx SWX-222-2 360° Dual-Tech Ceiling Occupancy Sensor 120–277V

Product Overview

The SensorWorx SWX-222-2 digital large-motion 360° ceiling sensor is a dual-technology occupancy sensor designed for commercial lighting automation applications requiring enhanced detection reliability. Combining passive infrared (PIR) and passive acoustic sensing technologies, this ceiling-mounted sensor provides dependable occupancy detection for offices, conference rooms, classrooms, break rooms, hallways, and other commercial interior spaces. Operating on 120–277VAC line voltage, the sensor directly switches lighting loads without requiring a separate power pack while supporting energy-saving automated lighting control strategies.

Key Features & Design

• Functionality: Dual-technology ceiling occupancy sensor utilizing PIR and passive acoustic detection to provide reliable 360° large-motion occupancy sensing for commercial lighting automation systems.
• Installation context: Intended for ceiling-mounted commercial lighting control applications in offices, conference rooms, classrooms, break rooms, vestibules, hallways, and similar interior spaces requiring dependable occupancy detection coverage. Supports mounting to ceiling surfaces, octagon boxes, and mud rings.
• Notable specifications: Operates on 120–277VAC input voltage with 360° large-motion PIR/acoustic coverage and approximately 2000 sq. ft. coverage area. Additional specifications include dual-technology sensing, adjustable time delays from 30 seconds to 30 minutes, 800W load rating at 120VAC, 1200W load rating at 277VAC, recommended mounting heights of 8–15 ft, compact low-profile housing, white finish, and UL Listed / RoHS compliant construction.
• Contractor-relevant details: Dual-technology PIR and acoustic sensing helps reduce false-offs in occupied spaces with intermittent movement, improving occupant comfort in conference rooms and offices. Line-voltage operation eliminates the need for external power packs, simplifying installation and reducing wiring complexity during new construction and retrofit projects.

Performance / Benefits
