レビインターホンシステム用切換ユニツト。[Scope of claim for utility model registration] (1) An intercom base unit with a monitor TV installed in each residential unit, and a plurality of doorphones with TV cameras installed adjacent to the common entrance etc. in correspondence with these base units. The slave device is connected to the telephone signal line for transmitting telephone signals and the video signal line for transmitting video signals through the main control panel installed corresponding to each dwelling unit, and each of the above television cameras is connected to A video selection line that transmits a video selection signal is connected between the doorphone slave unit and the corresponding main control panel, and each intercom base unit with a monitor TV in each residence can be called independently.
In an apartment house TV intercom system adapted to make calls, a switching unit is interposed between each of the slave units and the corresponding main control panel to connect and disconnect the call signal line and the video selection line. When a call is made by operating the call button provided on any of the above-mentioned door intercom subunits with a TV camera, the switching unit connected to the calling side The call signal line and the video selection line are each closed, and the call signal line and the video selection line of a switching unit other than the switching unit are opened, thereby causing the output from the calling side slave device to be output. Only the above-mentioned call signal and the above-mentioned video selection signal are transmitted to the above-mentioned main control panel corresponding to the slave unit, and the call and video are transmitted only between the base unit of the intercom with monitor TV corresponding to the slave unit on the calling side. A television intercom system for an apartment complex, characterized by displaying information. (2) A set of call signal terminals connected to the door intercom unit with TV camera and the main control panel by a call signal line, and connected to the door intercom unit with TV camera and the main control panel by a video selection line. It has a pair of video selection terminals and a set input terminal to be connected, and when a set signal is input to the set input terminal, it is held in the set state and opens a call signal line between the call signal terminals, When the call button of the corresponding slave unit is operated, the call signal transmitted from the slave unit via the call signal line is used as a reset signal, and when the reset signal is input, the reset state is switched and maintained. It has a set/reset circuit that closes the call signal line between the call signal terminals and outputs a switching control signal, and a set output terminal, and receives the switching control signal from the set/reset circuit and outputs the switching control signal between the video selection terminals. switching control means for continuously closing the video selection line and outputting the set signal from the set output terminal for a predetermined period of time. System switching unit.
