Abstract
A lighting control module for controlling power to a lamp is presented. The lighting control module comprises a receiver for receiving electronic communications from a central controller, a current sensor, a current controller for controlling current in a power circuit passing through the module, the current controller operating to open and close the power circuit, a control unit connected to the current controller and the receiver, the control unit operating to cause the current controller to open and close the power circuit in response to the communications, and an indicator connected to the control unit. The control unit causes the indicator to illuminate when the current sensor indicates that current fails to flow in the power circuit when the current controller is operated to close the power circuit.
