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.

Abstract: A load control system controls an electrical load provided in a space and comprises a load control device and a first occupancy sensor mounted to a movable structure (e.g., a door) and a second occupancy sensor mounted to a fixed surface (e.g., a wall or a ceiling).

The load control device turns on the load in response to receiving the occupied control signal from the first occupancy sensor, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors.

Abstract: A load control system comprises a load control device and a battery-powered occupancy sensor, which transmits a first wireless signal to the load control device in response to detecting the presence of an occupant in a space. The load control system further comprises a visual indicator for providing a visual indication when the magnitude of a battery voltage of a battery of the occupancy sensor has dropped below a predetermined low-battery voltage threshold. The occupancy sensor may comprise the visual indicator, such that the visual indicator is illuminated when the occupancy detects the presence of the occupant in the space and the magnitude of the battery voltage is less than the predetermined threshold. Alternatively, the load control device may comprise the visual indicator, such that the visual indicator is illuminated in response to receiving a second wireless signal, which is transmitting by the occupancy sensor when the magnitude of the battery voltage is less than the predetermined threshold.
