ABSTRACT:
A node is provided for operation in a control system comprising one or more master devices and one or more communications pathways operative to provide control signals from one or more of the master devices to the node. The node includes an electrical device configured to be controlled by one or more of the master devices. The electrical device includes a controller, a communication interface operably coupled to the controller adapted to permit communication between the controller and one or more of the master devices of the control system for controlling an operation of the controller, and an indicator operably coupled to the controller. The communication interface includes a radio frequency communication interface and is adapted to control the operation of the indicator to indicate whether or not the electrical device is operably coupled to a power supply.
