SAVE ENERGY AND MONEY WITH OCCUPANCY SENSORS AND VACANCY SENSORS
Occupancy Sensors are used to automatically turn lights on when you enter a room and off when the room is unoccupied. You can adjust the time delay
Vacancy Sensors require lights to be turned on manually, but will turn lights off automatically when the room is vacant.
Energy Savings - Sensors can provide significant energy savings, and are particularly effective in spaces which are occupied intermittently or are unoccupied but lights are left on for convenience or safety reasons. Ideal commercial applications include offices, classrooms, copy rooms, restrooms, storage areas, conference rooms, warehouses, break rooms, corridors, and filing areas. Occupancy sensors have become a standard feature in new construction and remain a proven energy-saving strategy for retrofits.
Types of Sensors - Some sensors work with passive-infrared (PIR) technology, some work ultrasonically, and some offer combined infrared/ultrasonic. Applications such as public restrooms with stalls require ultrasonic sensors. Some sensors are designed for wall mount and others for ceiling mount. All ceiling-mount sensors require the installation of a power pack. (Choose the appropriate technology)
Features - With many models, you can adjust the time delay to determine how long the lights will remain on after sensing vacancy. Some devices will sense ambient light and will not turn on if there is sufficient daylight. Motion sensitivity can also be adjusted on many models. Another feature to consider is coverage spread which is important, for example, in large spaces or where activity is concentrated at desk level.
Choose sensors according to application, light source, load, poles, and features. Commercial sensors are required for loads over 600 watts and for applications requiring a ceiling mount.
