Occupancy/Vacancy Sensor · 180° Coverage · Dual Technology PIR/Ultrasonic · Intermatic IOS-DOV-DT-WH
What this product is for
This in-wall line-voltage occupancy/vacancy sensor is used to switch lighting loads automatically in commercial and residential indoor spaces. It combines passive infrared (PIR) and ultrasonic sensing to improve presence detection where a single sensing technology may miss small movements or partially obstructed occupants.
Use for
Use for private offices, classrooms, meeting rooms, washrooms, hallways, utility spaces, and similar indoor areas where automatic lighting shutoff helps reduce wasted energy. It is compatible with LED, CFL, fluorescent, and incandescent lighting loads on 120/277 VAC circuits.
Avoid for
Avoid using this sensor outdoors, in wet locations, or where a neutral is not available. It is also not the right choice where 0-10 V dimming control is required, since this model is for switching rather than dimming.
Best for
Best for retrofit or new work where electricians need wall-switch replacement control with better detection in enclosed rooms, partitioned spaces, or areas with minor occupant movement. Dual technology sensing can help reduce nuisance switching compared with single-technology devices in more complex layouts.
Installed in
Installed in a standard wall box at typical switch height, with a maximum mounting height of 4 ft (1.2 m). Fits a standard decorator wall plate, which is included.
Why this product exists
This sensor exists to automate lighting control while giving installers adjustable settings for time delay, sensitivity, and ambient light response. Optional walk-through mode can shorten ON time for brief pass-through traffic, which is commonly useful in smaller enclosed spaces. Actual performance depends on room layout, partitions, mounting location, and local electrical code.
Compared with similar products
Compared with a PIR-only wall sensor, this dual technology model adds ultrasonic detection for improved minor-motion sensing. Compared with dimming occupancy sensors, this model is a simpler ON/OFF switching device for line-voltage loads and does not provide 0-10 V dimming control.
