A signal from the gas meter 18 is input to the microcomputer circuit section 14 via the meter interface circuit 19 at a constant flow rate.

The microcomputer circuit section 14 receives the signal from the meter interface circuit 19 and the input / output section 14
The value is added by the meter reading unit 14b via c, stored in the memory unit 14a, and compared with the remaining amount alarm value preset in the memory unit 14a.

When the added value of the signal from the gas meter 18 reaches a certain value set in the memory section 14a, or when the regular report date and time stored in advance in the memory section 14a and the clock counting section 14e are compared, When they match, the notification control unit 14d performs a notification operation.

After the notification, the relay drive circuit 15 and the relay drive circuit 17 restore the relay contact 9 and the relay contact 3 to switch to the telephone 4.

When not making a report, the microcomputer circuit section 14 inputs the signal of the current monitoring circuit 2 which outputs a signal when the loop current of the telephone line 1 is detected.

When the detection signal of the current monitoring circuit 2 is input, the telephone 4 is hooked off, the telephone 4 is judged to be in use, and the notification operation is not performed until the detection signal disappears. Further, in this case, the output of the operation signal output circuit 12 also outputs the signal during operation.

The operation signal output circuit 12 outputs an operating signal even when there is an input signal from the operation signal input circuit 13.

Further, the call monitoring circuit 8 detects that the DC circuit of the line connection circuit has gone off-hook in order for another automatic notification device connected to the connection terminal 7 to make a notification when this device is not making a notification.

Therefore, the second automatic notification device 23 operates the relay contacts 3 and 6 by the signal input from the call monitoring circuit 8. Then, the first automatic notification device 2
Since the output of the call monitoring circuit 8 of No. 2 is turned on, the relay contacts 3 and 6 are operated. Therefore, the telephone line 1 is connected to the dial transmission circuit 10 and the data transmission / reception circuit 11 of the third automatic notification device 24. In this case, the telephone line 1
As for the value of the DC resistance of the third automatic notification device 24 to the telephone line 1, only the DC circuit resistance of the current monitoring circuit 2 of the first automatic notification device 22 is connected.
