This is a bipolar (±24v) time-division multiplexed signal consisting of the following, and data is transmitted by pulse width modulation. When the address data of the transmission signal Vs received via the signal line 4 and its own unique address data match, each terminal device 2, 3 takes in the control data of the transmission signal Vs, and returns the transmission signal Vs. The monitoring data signal is converted into a current mode signal (signal #i4) in synchronization with the standby signal WT.
The signal is sent back by short-circuiting between the two via a suitable low impedance.

The central control device 1 also has a dummy transmission signal Vsl;
An interrupt signal Vi as shown in FIG. 3(b), which is constantly sent out and returned from one of the monitoring terminals 2, is received! Interrupt processing is performed by detecting the terminal device 2 that has generated an interrupt, accessing the terminal device 2, and causing the monitored data to be returned. - On the other hand, when the monitoring terminal 2 receives a monitoring input, it generates an interrupt signal Vi in synchronization with the start pulse signal ST of the dummy transmission signal Vs, and also generates an address confirmation mode transmission signal VS from the central controller 1. The central controller 1 responds to the monitoring input when the interrupt access mode transmission signal Vs is transmitted from the central controller 1 in response to an interrupt. Based on the monitoring data sent back from the monitoring terminal 2 to the central control device 1, control data to be transmitted to the control terminal 3 is created. Furthermore, the monitoring terminal 2 is provided with an individual operation switch 5 that individually controls a load 7 such as a light.
