FIG. 20 shows a conventional lighting system.
Some have the configuration as shown in FIG. The lighting system includes a monitoring terminal 70 having a human sensor unit and a plurality of lighting control terminals 71 connected to a control panel 73 via a transmission line 74. The output of the human sensor unit is monitored, and each lighting control terminal 71 controls and monitors the lighting state of the lighting fixture 72.

Here, individual addresses are assigned to the monitoring terminal 70, the lighting control terminal 71, and the lighting fixture 72, and the control panel 73 sends a transmission signal including the address to the transmission line 74. The monitoring terminal 70 and the lighting control terminal 71 are individually accessed to transmit and receive transmission signals.
