180° Dual-Technology Occupancy/Vacancy Motion Sensor Wall Switch | 120/277V | Enerlites MWOS

180° Dual-Technology Occupancy/Vacancy Motion Sensor Wall Switch, Single Pole | ENERLITES MWOS

The ENERLITES MWOS Dual-Technology Occupancy/Vacancy Motion Sensor Wall Switch delivers highly accurate lighting control by combining Passive Infrared (PIR) and Ultrasonic sensing technologies. This advanced dual-tech design minimizes false triggers while ensuring reliable motion detection in both line-of-sight and obstructed areas.

Featuring a 180° field of view, the MWOS provides up to 1200 sq. ft. of PIR coverage and 400 sq. ft. of ultrasonic coverage, making it ideal for offices, restrooms, classrooms, and commercial spaces. The sensor supports both Occupancy (Auto-ON/Auto-OFF) and Vacancy (Manual-ON/Auto-OFF) modes, allowing users to select the control method that best meets energy code requirements and user preferences.

The adjustable time delay ranges from 15 seconds to 30 minutes, while the built-in walk-through mode enhances energy savings by turning lights OFF after only 3 minutes when brief occupancy is detected. An integrated daylight (ambient light) sensor prevents lights from turning ON when sufficient natural light is present, even if motion is detected.

For convenience and flexibility, the MWOS includes a manual ON/OFF push-button, adjustable motion sensitivity, and a zero-crossing circuit to extend relay life and improve performance. Compatible with incandescent, CFL, and LED lighting, this single-pole wall switch requires a neutral wire for installation.

The ENERLITES MWOS is UL listed, California Title 24, Part 6 compliant, and backed by an industry-leading 5-year warranty, making it a reliable, long-term solution for energy-efficient lighting control.
