ABSTRACT:
An electrically powered annunciating system, for use in electrical panel boxes, having a sensing circuit including a first acoustic transducer to transmit a sonic signal to an annunciating circuit having a second acoustical transducer at a spaced distance from the first transducer to operate the annunciating circuit responsive to a sonic signal received from the first transducer. The sensing circuit powers the first acoustical transducer to produce a sonic signal responsive to a sensed electrical event such as termination of power to an electrical component. The annunciating circuit includes a tuned amplifier for signal purification and amplification, a time delay integrator to prevent accidental circuit operation caused by noise and an annunciator and a communication interface activated responsive to a sonic signal received by the second transducer. The annunciating system is particularly adapted for use in electrical panel boxes having multiple electrical components that are coupled by post and bus bar type connections, to alleviate the use of flexible wiring in the box for annunciating circuits.
