可能となる。(Function) According to the present invention, when a calling telephone is received, the called person who is on the intercom handset side is called by the intercom, and when a response is obtained, the pre-disconnection contact type relay is manually operated. Since the telephone line can be switched from the telephone to the intercom handset, it is possible to talk from the position of the intercom handset.
また、インタホン子機側に居る人が電話を掛けだいと思
った時に、この装置のインタホン親機を呼び出し、電話
を掛けてもらい通話したい当人が相手側の電話機に出た
時点で電話回線を電話機からインタホン子機側に切り換
えることによって直接通話ができることになる。Also, when a person on the intercom handset side wants to make a call, they can call the interphone base unit of this device, have the person make the call, and when the person they want to talk to answers the other party's phone, the phone line is disconnected. Direct calls can be made by switching from the telephone to the intercom handset.
