Abstract
A load control system has a system controller and a plurality of load control devices which receive power from a utility power source. The load control system includes at least one emergency load control device which receives power from a backup power source in the event of a power failure of the utility power source. The emergency load control device is configured to enter an emergency mode during the power failure of the utility power source, wherein in the emergency mode, the emergency load control device controls respective electrical loads according to emergency mode preset settings, and the emergency load control device transmits a message to the system controller to indicate the emergency load control device is in the emergency mode. The system controller is configured to transmit a message to the emergency load control device to exit the emergency mode when power from the utility power source is restored.
