PURPOSE:To monitor sensors connected to other terminal devices centralizingly at a main control panel, by selecting the on/off of a load corresponding to the on/off operation of each sensor freely, even if the sensors and loads connected to each terminal device are used for any application. CONSTITUTION:An output circuit 16a transmitting a signal to a signal line 6 and an input circuit 16b receiving a return signal returned in the current mode via the signal line 6 are connected to an operating circuit 17. A key switch 18 operates loads 41-4M manually for on/off operation nd switches 201-20N setting the function of the sensors 71-7N to ON or OFF type are connected to a switch function setting section 19. When the specific sensor 7x is set on, whether the corresponding specific load 4 is set on or off is determined with the switching operation of the switch 20x corresponding to the sensor 7x. Thus, through the switching of the switches 201-20N, the on/off operation of the sensor 7 is brought into a desired correspondence with the on or off operation of the load 4. |
