Abstract
A lighting control system includes a power pack and an enhanced occupancy sensor configured to implement multi-valued signaling to encode additional information into the occupancy signal it provides on the signal line. The power pack is configured to monitor the signal line to detect and interpret the additional information. In one example, the lighting control system also includes a manual override switch coupled to the signal line and/or to the occupancy sensor.
