Abstract
In various types of systems it is expedient to have a plurality of control consoles, each assigned a relative priority so that they may control the associated equipment in a predetermined hierarchy. The priority wiring requires only a pair of wires from one console to the next. A higher priority console, when activated, disables all lower priority consoles in the hierarchy and an indicator at each disabled console is activated to indicate the disablement. The indicator at the active console is not activated and the indicator at the highest priority console is, of course, never activated. Power to activate the disablement indicators is provided from the higher priority active console.
