Claim:
A light fixture comprising: a light, a housing that houses the light, and a control circuit comprising: an occupancy sensor, a control signal receiver, a control signal transmitter operatively connected to the occupancy sensor, a control element operatively connected to the occupancy sensor and to the control signal receiver, and an output from the control element, the output wired between the light and a source of power, wherein the control element controls the output to control power from the source of power to the light upon occupancy sensed by the occupancy sensor, wherein the control element controls the output upon wireless receipt of a first control signal by the control signal receiver, and wherein the control signal transmitter wirelessly transmits a second control signal upon occupancy sensed by the occupancy sensor, wherein the second control signal is the same as the first control signal in that the first control signal and the second control signal have a single format providing a same message that causes the control element to control the output, the single format being an uncoded signal format at a specified frequency of transmission.
