Abstract

In a doorphone system for an apartment house, it is possible to select optimum equipment arrangement according to the state of existing wiring. In the case of receiving a signal indicating a key number from an incoming AM signal identifier, a state controller determines whether or not the key number matches any one of the key numbers of room monitors stored in a connection destination storage. In a case where the key numbers match, the state controller determines that the room monitor of a communicating counterpart is connected to the own device, switches a connection destination of a first relay to a third relay side, connects the second relay, connects the third relay to the terminal corresponding to the matched key number, and opens a communication path between the room monitor of the communicating counterpart and a lobby interphone.
