ABSTRACT:
A load control system controls an electrical load provided in a space and comprises a load control device and one or more occupancy sensors. The load control device controls the load in response to the wireless control signals received from the occupancy sensors. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The load control device turns on the load in response to receiving the occupied control signal from at least one of the occupancy sensors, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors. The load control device is operable to determine that no wireless control signals have been received from the occupancy sensors for the length of a predetermined timeout period and to subsequently turn off the load.
