The Leviton Sector intelligent ballast and lighting control is a three-in-one integrated system that combines occupancy sensing, daylight harvesting, and dimming control, helping installers to save wiring time and end users to save energy. Sector uses the same wiring type for all components and accessories in the suite, and all components are on a single bus with accessories connected to the network rather than to the ballast. Using infrared and ultrasonic technologies, the ceiling-mounted Multi-Technology Occupancy Sensor (right) reduces energy costs 34% to 60% by employing self-adjusting, smart, or customized settings to extinguish lights when a room is not in use. The Sector Network Photocell measures ambient light levels to reduce unnecessary artificial lighting, and the Sector 5-Button Digital Switch (left) manually controls dimmable and nondimmable lighting.
