In the figure is the 8-line digital display superior alarm circuit. This circuit consists of the timed stereo circuit, 8-line encoder, decoder, digital display circuit and so on. IC1(CD4532) is the octal prior encoder, and the 8-line input control wires are connected with K0~K7 eight switches, when the input control wire is cut off due to some condition, then input a corresponding high LEV, the encoder will program a 3-bit binary address code. If there are more than 2 lines of wires cut off, the encoder will react to the line of the superior stage.
