Abstract

A coordinating unit receives an input signal from the ringing circuit of a telephone, a doorbell switch, the timer of a washing machine, or the like. The coordinating unit, through a program muting circuit reduces the volume of televisions, radios, or the like, in the home and signals of the presence of an input signal by ringing a prescribed chime or chimes associated with the particular input signal. Also, a switching feature is incorporated in order that the power may be removed from certain preselected sockets in the home to eliminate noise from machinery such as power tools or vacuum cleaners. Furthermore, an outdoor signaling device can be operated by the coordinating unit for flashing lights and buzzers mounted exteriorly of the house.
