Abstract:
An area lighting control system is provided for a light fixture and occupancy sensors. In a pairing mode, the occupancy sensors transmit messages with respective unique addresses to the light fixture, which identifies an associated sensor network. Upon lapsing of the pairing mode, an operating mode follows during which the sensors transmit output signals representative of occupancy in the area, and the light fixture regulates respective light sources based on an occupancy state determined according to output signals received from the associated network. The output signals are transmitted according to pseudo-random time intervals in order to reduce wireless transmission collisions, and only upon determining no occupancy in the defined area. When signals are received from all sensors in the network during a predetermined time period, the light fixture dims the light sources, whereas otherwise the light fixture operates the light sources at full lighting state.
