by AF 0206 c3 — February 15, 2010 — WattStopper has introduced four multi-way wall switch occupancy sensors for code-compliant lighting control in commercial spaces with more than one entrance or switch location.
The sensors provide convenient full-function multi-way control and install easily using traditional three- and four-way wiring, according to the company. The product offering includes what Wattstopper describes as the industry’s first dual relay multi-way occupancy sensors, facilitating economical control of bi-level lighting or multiple loads. Multi-way sensors are available in passive infrared (PIR) and WattStopper’s patented dual technology models.
The multi-way sensors provide out-of-the box automatic-on operation, and turn lighting on whenever any one of the connected sensors detects occupancy. Dual relay sensors are factory configured to turn only the first load on automatically; a control strategy shown to save the most energy. Lighting can be turned off manually from any of the sensors, and if manual-on operation is preferred, sensors may be quickly adjusted while installed in the wall box. When the space is no longer occupied, lighting will automatically turn off following a time delay that begins when the last sensor ceases to detect occupancy.
