御システム。The main operation panel and multiple terminal devices are connected to each other via signal lines, and address signals, control data signals, and return standby signals are transmitted from the main operation panel to the terminal devices, and the voltage changes on the signal lines are transmitted. A photocoupler that detects the transmitted address signal and control data signal, a constant voltage clip circuit that is inserted before the photocoupler and regulates the upper limit of voltage change on the signal line, and a signal line that detects the transmitted address signal and control data signal. A remote monitoring and control system that is equipped with a return circuit on the side of the terminal entrance that sends back a monitoring signal to the main operation panel as a change in current on the signal line by changing the line-to-line impedance of the signal line.
