UL LISTE D
General
Specification
Commercial Grade
In-Wall Occupancy/Vacancy Sensor
Model #: MWOS
Integrated PIR and Ultrasonic sensor technology to detect very fine motion and provide accurate motion sensing
Allows to choose triggering when both technologies detect motion or when only PIR detects motion
Less false trigger, fast ON/OFF; commercial grade sensor for closet, garage, hotels, meeting room, work places
Adjustable timeout from 15 seconds to 30 minutes; Walk-Through mode: 3 minutes if no activity after first 30
seconds
Description: This Multi-Technology Wall Switch Sensor combine advanced passive infrared (PIR) and ultrasonic
technologies into one unit. The combined technologies helps eliminate false triggering even in difficult applications.
Selectable operating modes allow the sensor to turn a load on, and hold it on as long as either or both technologies
detect occupancy . After no movement is detected for the selected time delay, the lights switch off.
A "walk-through" mode can turn lights off after only 3 minutes, if no activity is detected after 30 seconds following an
occupancy detection.
This sensor also contains a light level sensor. If adequate daylight is present, the sensor holds the load OFF until light
levels drop, even if the area is occupied.
