(Installation of photoelectric composite communication system)
Next, the installation operation of the photoelectric composite communication system 700 will be described.
First, as in the first embodiment, the information distribution device 710 is installed at a predetermined position of the house 101 and the commercial AC power line 211 is connected to the main breaker 210. In addition, each interface device and the photoelectric composite outlet 730 are appropriately installed at predetermined positions of the house 101.
Then, the photoelectric composite connection cable 740 is connected to the photoelectric composite conversion device 711 of the information distribution device 710, and the photoelectric composite branch device 720 is connected to the end of the photoelectric composite connection cable 740 to branch the photoelectric composite connection cable 740. However, the photoelectric composite outlet 730 is connected. Further, each interface device is connected to a photoelectric composite outlet 730 in the vicinity by a photoelectric composite connection cable 740, and the photoelectric composite communication system 700 is constructed in the house 101.

Is common. Accordingly, the power terminal 621 of the photoelectric composite connection cable 740 is inserted into the power terminal insertion slot 233 and connected to the power terminal receptacle 234, while the connection terminal 832 is inserted into the terminal insertion slot 812 to the terminal receptacle 813.

By connecting these photoelectric composite connection cables 740, the terminal brackets 813 of the interface device are connected to each other. Therefore, the detection unit of the photoelectric composite conversion device 711 is connected via the photoelectric composite connection cable 740 and the photoelectric composite branch device 720. The terminals 811 are short-circuited. Thus, the DC power supplied from the converter 801 is supplied to the relay circuit 802, the relay circuit 802 is closed, and commercial AC power is supplied from the sub-breaker 220 to the photoelectric composite converter 711. Thus, the photoelectric composite conversion device 711 to which the commercial AC power is supplied supplies the commercial AC power to the interface device via the photoelectric composite connection cable 740 and the photoelectric composite branching device 720. The interface device to which the commercial AC power is supplied acquires low-voltage DC power for control from the commercial AC power, and can convert and control various signals to optical signals. The optical signals are information distribution devices 710. To be aggregated.
Further, since the photoelectric composite outlet 730 is in a state in which the terminal brackets 813 are open, the detection unit terminals 811 of the photoelectric composite conversion device 711 of the system to which the interface device is not connected are open. For this reason, the DC power from the converter 801 is not supplied to the relay circuit 802, and the open state is maintained.
