is a sensor contact, 25 is an output contact, 11 is an audio ROM
, 12 and 15 are amplifiers, 13 is a hybrid circuit, 14 and 19 are transformers, 16 is a PB signal decoder (DTMF DCR), 18 is a calling signal generation circuit, 20 is a DC blocking capacitor, 21 is a photocoupler, 22, 23 is a resistor, 26 is a RAM, 27 is a ROM, 28 is a DC loop current, and 32 is a call switching contact (
33 is a DC power source for loop detection, 34 is an incoming call detection circuit, and 37 is a relay (RL).

Next, the circuit operation will be explained. The remote telephone voice notification control device shown in FIG. 2 is controlled by the CPU 5.
and a program burned into the ROM 27 in the CPU 5. First, input I/O port (1
) 6 is closed, the CPU 5 detects the input and connects the output I/O port (
4) Calling signal 16Hz, 75Vrm via 17
s is sent from the calling signal generating circuit 18 to the central office line 4 via the transformer 19 and the DC blocking capacitor 20.

As a result, the bell of the telephone 2 rings and when answered, a DC loop is formed on the office line side of the telephone 2, and a DC loop current 28 is generated on the office line 4 by the DC power supply from the loop detection DC power supply 33. flows in, and the photocoupler 21
is turned on, and the input I/O port (3) 24 is connected to the CPU 5.
It is sent as a response signal to. When the CPU 5 confirms the response, it stops the calling signal generation circuit 18, then accesses the audio ROM 11 from the output I/O port (6) 8, and reads the notification signal corresponding to the input I/O port (1) 6. Messages (e.g. "No. 1 window has opened", "Gas sensor has worked", "Customer has arrived", etc.) are sent to central line 4 via amplifier 12, hybrid circuit 13, and transformer 14. and transfers it to telephone 2.

The above is the operation of the remote notification function, and since it is possible to install a plurality of contacts 10 of the input I/O port (1) 6, by installing the audio ROM corresponding to each, the operation shown in the example can be performed. It becomes possible to send out any of a plurality of messages such as the above in response to an input.

Next, the remote control operation will be explained. When the telephone 2 hears the input message from the remote telephone voice notification control device during remote notification operation and outputs a control signal by pressing the PB button, the control signal is sent to the transformer 14, hybrid circuit 13, Amplifier 1
5, PB signal decoder 16, input I/O port (5)
The control signal is transferred as a BCD code to the CPU 5 via the CPU 9.

The CPU 5 interprets this code and operates the output contact 25 via the corresponding output I/O port (2) 7. When performing an output operation, in combination with the audio ROM 11 described earlier, a confirmation message (for example, "Do you want to sound an alarm? If you agree, please press #")
"Please press the button") can also be sent to the telephone.

In the operating state described above, the contact 32 of the relay 37 disconnects the central office line 4 from the telephone exchange so that it does not affect the telephone exchange. When the telephone receives an incoming call from the telephone exchange, the incoming call detection circuit 34 operates, and the CPU 5 receives the call from the I/O port (7) 35.
The CPU 5 operates the relay 37, switches its contact 32 (rl), and connects the telephone to the telephone exchange. This allows the phone to, when there is no incoming call,
Remote voice notification and remote control are performed with the remote telephone voice notification control device, and when there is an incoming call, it can immediately respond to the incoming call without any hindrance and perform its original function as a telephone. Please refer to FIGS. 3 and 4 as they are flowcharts showing the operation of this embodiment described above.
