Dual Technology Ultrasonic and Passive Infrared Line Voltage Wall Mount Occupancy Sensor

Model: MDW-V Description:120/277VAC Single Pole, Dual Technology Line Voltage Occupancy Sensor Combines Advanced Passive Infared(PIR)and Ultrasonic Technologies into One Unit.


Dual Technology Ultrasonic and Passive Infrared Line Voltage Wall Mount Occupancy Sensor

This Dual Technology Occupancy Sensor combines advanced passive infrared (PIR) and ultrasonic technologies into one unit. The combined technologies help to avoid false triggering even in difficult applications. The MDW-V turns lighting on and off based on occupancy and ambient light levels.

The sensor offers numerous operating modes that can be combined to create the ideal custom control. Selectable operating mode 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 the lights off after only 3 minutes, if no activity is detected after 30 seconds following an occupancy detection.

This sensor 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.

The MWD-V provides an eliptical coverage pattern. The coverage shown repersents walking motion at a mounting height of 10

 feet.  For building spaces with lower levels of activity or with obstacles and barriers, coverage size may decrease.
