Abstract

A lighting control module (LCM) includes an input configured to receive, from a sensor, a signal indicative of motion and/or occupancy, and to output a first corresponding signal. The LCM includes a microprocessor to receive the first corresponding signal from the input and, in response, transmit a second corresponding signal. A wireless transceiver is communicatively coupled to the microprocessor and configured to communicate with other LCMs. A relay is configured to selectively provide power to an output that is configured to be electrically coupled to a fixture. The relay is configured to selectively provide the power to the output according to a first relay-control signal from the microprocessor. The LCM also includes a regulated power supply, a power input configured to couple the power supply to an external power source, and a dimming module configured to be coupled to the fixture and to, when coupled to the fixture, output a signal to the fixture. The LCM is configured to receive from the sensor the signal, and in response to the signal cause the fixture to change its state of operation.
