, a telephone number setting device for setting the telephone number of C, θ4
) is the speaker that generates the alarm sound, (15) is the voice response unit that generates the message of emergency call or answering when you are away, (16) is the sound collection microphone that collects the ID status sound, and θ is the telephone line (4). a control code receiving unit (1 hinoki is a switching contact, θ9) that receives a control code signal sent through the control code signal and inputs the control code data to the control unit (10);
(20aX20b) is the input/output interface.The operation of the embodiment will be explained in detail below.In Figure 4, the abnormality detection signal vE is output from the abnormality detection sensor fl). This is a basic flowchart when there is an emergency input to the telephone terminal device (X) via the supervisory control device (6). If there is an emergency input, immediately call the first contact point A.
The phone number is read from the phone number setting device 0, and when the first call destination A responds, an emergency call message (for example, "This is XXX's home. A fire has broken out. Please confirm. ), and when a predetermined confirmation control code (for example, a 4-digit number) is sent by operating the telephone, the telephone line (4) is opened and the emergency alert is terminated. On the other hand, if the first callee does not respond or the specified confirmation control code is not input even after responding (for example, if a child or elderly person who does not understand the meaning of emergency calls responds), the first call It is determined that the emergency report has not been transmitted to the predecessor (17), and the second report destination B is transferred to make the same emergency report as described above. Also,! If the emergency report is not reliably conveyed to the 2nd notification destination B, the emergency report is sent to the 3rd notification destination C, and the emergency report is sent to the 3rd notification destination C.
If the emergency call is not transmitted, the first callee is contacted again and the emergency call is repeated n times. In addition,
Control code for checking the above, control code/monitor for sound collection or selection control code/monitor for selecting various devices (7) for performing inversion control, inversion control 0-I
A control code instructing L, etc. is sent out by operating a button on the telephone, and a control code signal sending a frequency corresponding to the number is received by the control code receiving unit Oη and converted into control code data. Further, the switching contact 08) is first switched to the voice response unit 05) for generating an emergency message, and after the sending of the emergency message is finished, it is switched to the control code receiving unit θ power.

Next, when a sound collection control code is sent from an external notification destination (for example, A) that received the emergency message, the control unit (10) receives this sound collection control code and contacts the switching contact (18). ) for a predetermined sound collection operation section 11.
6) and transmits the sound collection signal output from the sound collection microphone (+6) to the reporting destination A via the telephone line (4).

At this time, the alarm sound emitted from Shuhiga α4) is stopped for the operation stop period t2, so in the I center section of the sound collection operation period t1, the situation sound that is not disturbed by the alarm sound is transmitted to the destination A, and the emergency notification is This allows you to clearly hear the sounds of the current situation, allowing you to accurately grasp the situation. Further, the start end of the operation stop section t2 of the alarm means (2) that emits the alarm sound is set slightly later than the end of the sound collection operation section 1.0, and the end of the operation stop section t2 is the sound collection operation section t! is set slightly earlier than the end of the sound collection operation section 1+, and at the start end tza and the end end L+b of the sound collection operation section 1+,
Since the alarm sound is collected as a situational sound by a sound collecting microphone (national sound) and transmitted to the person to whom the report is being made, it is possible to confirm that the tip-off means (2) is operating normally, and the tip-off means (2) It can be confirmed that the home phone is working again.In addition, a pager carried by a family member who is out of the house may be set as the first notification destination A, and in this case, the family member will immediately call the phone number of the home when the family member is away. , calls the telephone terminal (X), sends a control code to monitor the emergency input in the control code reception section following the answering message from the telephone terminal (X), and checks the type of emergency input ( In addition to detecting fires, gas leaks, etc., the system also sends out sound collection control codes to listen for situational sounds.

〔Effect of the invention〕
