Each of remote control groups (GR) is provided with room units (20, 20, ...) which are set by one primary device (2a) and secondary devices (2b) which are interlocked with the primary device (2a). A central monitoring board (30) is provided for transmitting signals from/to the room units (20, 20, ...). In the memory of the board (30), a class area (M2) is provided for storing the class data of the primary device (2a) and the secondary devices (2b). The board (30) transmits operating signals to the room unit (20) provided with the primary device (2a) based on the class data stored in the area (M2). In addition, the board (30) identifies the room units (20, 20, ...) which start operations in response to the operating signals as one group (GR) and registers the group (GR) in a group area (M3). <IMAGE> |
