  Further, the key telephone 10 </ b> A has a control circuit 16 configured by a microcomputer or the like, and this control circuit 16 is connected to the codec 14 and the extension interface 15. Further, various keys 17 such as dial keys and function keys are connected to the control circuit 16, and an LCD 18 is connected as a display for displaying the incoming call number.

  Further, the key telephone 10 </ b> A includes a sensor 19. The sensor 19 is a fire sensor that detects fire in the premises with heat or smoke, a human sensor that detects intruders on the premises, and the sensor output is supplied to the control circuit 16. Furthermore, although explanation and illustration are omitted, the other key telephones 10B to 10N are configured similarly to the key telephone 10A.

  On the other hand, in this example, the main apparatus 20 is a case where three ISDN lines 41 to 43 are handled as telephone lines. The extension interfaces 21A to 21N for N units, the exchange switch 22, and the lines for three lines are used. Interfaces 231 to 233. The key telephones 10A to 10N are connected to the exchange switch 22 through the extension interfaces 21A to 21N, and the exchange switch 22 is connected to the telephone lines 41 to 43 through the line interfaces 231 to 233.

  The main device 20 has a control circuit 24 configured by a microcomputer or the like. The control circuit 24 detects the states of the extension interfaces 21A to 21N and the line interfaces 231 to 233, and controls the extension interfaces 21A to 21N, the exchange switch 22 and the line interfaces 231 to 233 to make outgoing and incoming calls. Realized. Further, for example, a routine shown in FIG. 3 is prepared in the control circuit 24 as an alarm program executed by the microcomputer in the event of an abnormality.

  Further, the main device 20 includes a report destination memory 27 and a voice storage circuit 28. In this case, when an abnormal situation such as an intruder or a fire is detected, the report destination memory 27 is prepared with data on the telephone numbers of the police, fire department, security company, etc., which are the report destinations. A correspondence table of 10N and its installation location is prepared. Also, the voice storage circuit 28 is provided with voice data for reporting a report for each report content.

  The main device 20 includes a power supply circuit 25 whose operating power is input as a commercial AC voltage, and a rechargeable battery 26 for backup during a power failure.

  In such a configuration, during normal times, the key telephones 10A to 10N and the main apparatus 20 execute processing in the same manner as the normal key telephones and the main apparatus. For example, when a call is made from the key telephone 10A, the key telephone 10A is connected to an available telephone line among the telephone lines 41 to 43 through the exchange switch 22, and thereafter, outgoing calls and telephone calls are realized.

  On the other hand, when an abnormality such as an intruder or a fire occurs, the abnormality is reported by the routine shown in FIG.

  Furthermore, since the alarm sound is also output simultaneously from each speaker 13 of each of the key telephones 10A to 10N, it is possible to threaten the intruder and notify the security guard even when the security guard is patroling the premises. can do. Furthermore, if any of the lines 41 to 43 is free when an abnormality occurs, use that free line. If there is no free line, forcibly disconnect one of the lines. It is possible to report abnormalities by using from. If necessary, you can also report to two or more locations at the same time.

  In the telephone system shown in FIG. 4, the network interface 234 is connected to the exchange switch 22 of the main device 20, and this network interface 234 is connected to the WAN 50 through the cable 44. Therefore, in this case, information regarding the alarm can be exchanged with the WAN 50 as well.

  In the above description, the sensors 19 are provided in all the key telephones 10A to 10N. However, the sensors 19 can be provided only in some of the key telephones, or one of the key telephones can be detected. A plurality of different sensors can also be provided. Further, the sensor 19 can be externally attached without being incorporated in the key telephone.

  Furthermore, the start and release of the security can be performed by the button operation of the main device 20, but when the predetermined key operation is performed on any key 17 of the key telephones 10A to 10N, the start or release of the security is started. Can also be executed. In that case, for example, if the security is started one minute after the key operation for starting the security and the notification is made one minute after the sensor 19 detects the person, the key operation is performed. People are not reported as intruders.

  Further, the start and release of security can be performed by grouping the key telephones 10A to 10N into groups. Further, at the time of reporting, it is possible to connect a modem instead of the voice storage circuit 38 and send out data notifying the abnormality instead of the voice data. Moreover, it can replace with a key telephone and a main apparatus, and can also be set as an IP telephone and a call control server.
