Unison Echo® Occupancy & Vacancy Sensors can cut down on wasted electricity. They automatically detect motion, and can be used for either occupancy or vacancy detection in areas up to 2,000 square feet, ensuring a space is only lit while in use. Echo Sensors are perfect for conference rooms, custodial closets, restrooms and other areas that are empty for a long period of time.
