A second transmission master station (3B is provided in a control panel (3), so that a first transmission master station (1A) and the second transmission master station (3B) independently issue a control command to first transmission slave stations (2a, 2b, ... 2z) in a second room (2) to control a load and collect state monitoring information on the load, thus, even if the first transmission master station (1A) in a first room (1) stops, a control operation over the load and a load state indication from the control panel (3) are possible even during the stop period. |
