A lighting control system includes an enhanced occupancy sensor and/or an enhanced power pack, allowing for more sophisticated and/or accurate lighting control and energy management capability. In one example, the occupancy sensor provides additional information, such as information about movement detected in the monitored area, in the form of a signal superimposed on the occupancy signal, and a specialty power pack is configured to detect and respond to the superimposed information signal, thereby providing enhanced functionality to the lighting control system. The superimposed signal conveying the additional information is made high-speed/short-duration such that it is “invisible” to a conventional power pack and the occupancy sensor remains compatible with conventional power packs. The enhanced occupancy sensor may therefore be used seamlessly with both conventional and specialty power packs, and may be implemented as a “drop-in” component for legacy lighting control systems.
