PROBLEM TO BE SOLVED: To flexibly correspond to a system configuration so that it can be installed easily and surely without impairing usability. SOLUTION: A terminal device 3A, 3B, ..., 3G measures a voltage drop unit 16 that drops an input voltage and outputs a voltage, and a voltage at one side end and the other side end of the voltage drop unit 16. It includes a voltage measuring unit 15 and a control unit 13 that sets an identification code so that the order of connection from the control device 2 can be determined based on the voltage measurement result and notifies the control device 2 of device information. The control device 2 raises the voltage of the cable to a constant voltage and holds it for a certain period of time at the start of power supply to the terminal devices 3A, 3B, ..., 3G, and then based on the identification code and the corresponding device information. Controls a plurality of terminal devices 3A, 3B, ..., 3G. [Selection diagram] Fig. 2
