Abstract:
A multiple dwelling house interphone system includes a centralized collective entrance machine for a visitor to call a dweller of any building, a dwelling unit master device provided to each dwelling unit for a dweller to respond to a call, and a centralized controller which controls communication between the centralized collective entrance machine and each dwelling unit master device. Each dwelling unit master device has an ID storage section storing its own ID. When the ID of the dwelling unit master device is inputted for calling the dweller, a centralized collective entrance machine control section of the centralized collective entrance machine first transmits an ID confirmation request signal to all the dwelling unit master devices and waits for a reply from the corresponding dwelling unit master device, and next, transmits a call signal to the dwelling unit master device that has returned a reply signal.
