..., 7-n) are connected. In addition, as the sensors, switches for security bells, emergency bells, fire alarms, etc. (not shown) may also be provided.

Both the central monitoring device 1 and the terminal device 3 have a CPU and memory consisting of a microprocessor, etc., and each CPU
Under the control of U, data are transmitted to each other via transmission line 2. That is, as illustrated in FIG. 2, the central monitoring device 1 receives the start signal ST, the communication partner terminal 3-k,
A message consisting of address data ADRk specifying the address data ADRk, transmission data CNTk to the terminal 3, end signal END, etc. is cyclically sent to the transmission line 2, while the terminal 3- specified by the address data ADRk Transmission data C
TRk is taken in from the transmission line 2, and return data REPk containing predetermined data such as monitoring information to be described later or data designated by the transmission data CTRk is sent to the transmission line 2. This data REPk is received by the central monitoring device 1.

A control program for the CPU 12 is stored in the memory 11 of the central monitoring device 1.
M) In addition to the area, there is a transmission data area prepared in the same number as the number of terminals, in which data to be sent to each terminal is temporarily stored, and a transmission area in which address data for specifying the third terminal to communicate with is temporarily stored. When the monitoring information from the destination address counter and the terminal 3 includes alarm data, which will be described later, a reception data area is provided for temporarily storing the address data and alarm data of the terminal.

The central monitoring device 1 also includes an audio information selection instruction section 12 which selects and instructs audio information suggesting the content based on the address data and alarm data of the terminal stored in the reception data area. A speech synthesis unit 13 that generates an audio signal based on instructed audio information. ．．
An analog switch 15 that closes according to instructions from the CPU 12 and sends the output of the voice synthesizer 13 to the public telephone line 14.
It is equipped with

The reporting device 16 has a so-called auto-dial function,
A partner station instructed by the CPU 12 is called by this device.

In this embodiment, the terminal 3 has sensors 4°5.6
When any of the sensing signals is input, an alarm corresponding to the input signal is issued from the alarm display device 7, and alarm data is created. Note that the above-mentioned alarm continues until the sensing signal is no longer input. This alarm data includes monitoring information RE to which start signals, end signals, parity pits, and other data are added as desired.
It is sent to the central monitoring device 1 as P. Note that when none of the sensors is generating a sensing signal, monitoring information RFP including no-alarm data is sent out instead of alarm data. Further, when alarm data created by another terminal is transmitted (answered back) via the central monitoring device, the alarm display device generates an alarm of a type corresponding to this alarm data.

The central monitoring device 1 includes a memory 1 as shown in FIG.
The aviles data ADRk set in the transmission address 9 counter of No. 1 is sent to the transmission line 2.

Terminal 3- constantly monitors the signal on transmission line 2 and is in standby mode until its own station is called, but the above address A
Since DRk is the address of the own station, the above-mentioned monitoring information is sent to the transmission line as reply data REPk.

After transmitting the address data ADRk, the monitoring device determines whether alarm data is set in the transmission data area corresponding to the address data ADRk.

If the alarm data is set, the alarm data is sent as the control data CTRk in FIG. If not, the terminal 3-k continues without sending the control data CTRk.
The monitoring information RFP,k sent from the transmission line 2 to the transmission line 2 is received. Subsequently, it is determined whether the received monitoring information REPk includes alarm data. If alarm data is included, the type of alarm data and the terminal address ADRk are stored in the reception data area of the memory 11; if the alarm data is not included, the terminal address ADRk is stored in the reception data area.
