SensorWorx SWX-221-B Wireless Ceiling Mount Dual-Tech Occupancy Sensor, 360°, Battery Powered

Product Overview

The SensorWorx SWX-221-B is a wireless, battery-powered ceiling-mounted dual-technology occupancy sensor designed for commercial lighting control systems. It uses passive infrared (PIR) and acoustic sensing to detect occupancy and wirelessly signal connected load controllers to manage lighting based on room activity.

Key Features & Design

• Functionality: Detects occupancy using dual-technology sensing (PIR and acoustic) and wirelessly signals connected load controllers to manage lighting based on room activity..
• Installation context: Ceiling-mounted and wireless for straightforward installation, with retrofit-friendly potential and minimal wiring required.
• Notable specifications: Dual-technology sensing (PIR and acoustic); 360° small-motion coverage up to approximately 500 sq ft; battery-powered wireless operation; ceiling-mounted installation with occupancy-based control through linked load controllers.
• Contractor-relevant details: The wireless ceiling-mount design simplifies retrofits and new installations, reducing cabling and enabling quick deployment in classrooms and offices while supporting efficient occupancy-based lighting control.

Performance / Benefits

In real-world use, the SWX-221-B provides reliable 360° occupancy sensing to ensure lights operate only when spaces are occupied. The wireless, battery-powered design minimizes installation disruption and enables flexible placement, delivering energy savings and improved occupant comfort in offices, classrooms, and other commercial environments.
