Ceiling-mounted device that integrates Lutron wireless and wired sensors and controls through the QS communication link to Energi Savr Node (ESN) units, GRAFIK Eye QS control units (models starting with QSGR), Quantum systems, Sivoia QS shades/draperies, and myRoom control modules. Uses Clear Connect RF Technology for communication with Radio Powr Savr occupancy and daylight sensors, and Pico wireless controllers. QSM connects to four Lutron wired sensors or controls - occupancy sensors, daylight sensors, EcoSystem infrared (IR) receivers, or EcoSystem wallstations. Does not apply to wireless only models. Powered by the QS link - no line voltage connections are required.
