Sensor Switch Open area office lighting control is made cost effective with the use of the nCM PDT 9 Series Standard Range 360° occupancy sensor. This small, yet powerful sensor provides line of sight PIR detection of small motion in a circular pattern and combines overlapping Microphonics™ coverage for detection of occupants working in their cubicle space. By installing multiple nCM PDT 9s on 30' (9.14 m) centers, large zones are created (typically one per circuit of lighting). The lighting is then controlled in blocks similar to manual switching. Restrooms with stalls, large storage areas with shelving, and libraries with study carrels are also easily and cost effectively controlled by the nCM PDT 9.
