る通話回路とを備えたインターホン装置。 In an intercom device that allows intercom calls between calling and receiving terminals that have set a tuning number via a bus cable, there is a tuning number setting switch that sets the tuning number, and a voltage that is set by the tuning number setting switch. A ladder resistor that outputs a change as an analog signal, a CPU provided with an A/D conversion circuit that converts the analog signal input from the ladder resistor into a digital signal, and a CPU that decodes the digital signal are selected from the originating terminal. An intercom device equipped with a communication circuit that allows an intercom call between a calling terminal and a receiving terminal when a station number is input.
