Abstract
An apparatus for and method of inhibiting and overriding the normal operating mode of an input device connected to a communications network function within an electrical network made up of input devices, with a group of the input devices being capable of commanding an electrical control device to apply and remove electrical power from an electrical load. The input devices or nodes communicate with the electrical control device over the communications network. When one of the input devices is turned off, the normal operating mode of all of the other input sensors is inhibited. The electrical control device remains inhibited until all of the input devices are no longer in the off position. Thus, electrical power to the load controlled by the electrical control device remains disconnected until all input devices are in the on position. Local and remote signaling, control, and indication diagnostic and monitoring functions are also performed.
