装置。In a composite intercom device constituted by a slave unit, an indoor unit, and a base unit, the base unit includes a calling circuit that operates a call oscillator in response to a call from the slave unit; a time limit circuit for setting a time for establishing a communication path with the handset for a predetermined period of time; and a time limit circuit for setting a time for establishing a communication path with the handset, and a time limit circuit that establishes the communication path with the handset when the base unit or the indoor unit responds within the predetermined time. The device is characterized by being provided with a call control circuit that controls a call switch circuit that opens and closes, and a holding circuit that stops the time-limited operation of the time limit circuit during a call between the base unit and the slave unit or between the base unit and the indoor unit. Composite intercom device.
