Reference numeral 5 has relay contacts b1 and b2.

When the control circuit 5 receives the emergency signal from the sensor 8, the control circuit 5 sends a relay drive signal to the relays A14 and B15, operates the relays A14 and B15, and receives a dial tone signal via the reporting circuit 4. If the dial tone signal is not received even if the emergency call circuit 12 is driven and the relay A14 is operated, the relay A14 is deactivated and operated at least once to keep the ordinary telephone 2 from the telephone line 3 for a certain time. If the dial tone signal is input during the relay A14 operation during the above disconnection, the emergency call circuit 12 is driven.If the dial tone signal is not yet input during the relay A14 operation, the emergency message transmission circuit 13 is forcibly driven. Then, the emergency message is sent to the telephone line 3 via the relay contacts a1 and a2.

The operation of the emergency notification device 1 of the present invention will be described.

When the control circuit 5 of the emergency notification device 1 receives the emergency signal from the sensor 8 when the general telephone 2 is talking to the outside through the telephone line 3, the relay A14 and the relay B15 operate,
The contacts a1 and a2 are closed, the telephone line 3 is connected to the alarm circuit 4, and b1 and b2 are closed to prepare for connection to the call back telephone 7. At this time, the connection between the ordinary telephone 2 and the telephone line 3 is released, and when the relay A14 is restored,
The call back telephone 7 is connected to the telephone line 3.

By the way, if the general telephone 2 is calling through the telephone line 3 to a subscriber other than the police or fire department, the telephone line 3
After disconnecting the connection between the telephone and the general telephone 2 for a certain period of time and restoring the exchange (not shown), if the alarm circuit 4 is connected to the telephone line 3, the alarm circuit 4 can receive the dial tone signal. . However, if the ordinary telephone 2 is calling a subscriber with a special destination number such as police (110) or fire department (119), even if the ordinary telephone 2 is disconnected from the telephone line 3 for a certain period of time or more, It is well known in the art that the exchange cannot be restored unless a subscriber such as a police or fire department goes on-hook. For this reason,
When the general telephone 2 is calling a police station or a fire station, the alarm circuit 4 cannot receive the dial tone signal unless a subscriber of the police station or the fire station goes on hook.

Therefore, when the control circuit 5 receives the emergency signal from the sensor 8 to operate the relays A14 and B15, and the control circuit 5 cannot receive the dial tone signal via the alarm circuit 4, the relay The non-operation and operation of A14 are performed a predetermined number of times (one or more times), the ordinary telephone 2 is disconnected from the telephone line 3 for a certain period of time or more, and the control circuit 5 issues the alarm circuit 4
If the dial tone signal can be received via
It may be presumed that the general telephone 2 was calling a subscriber other than the police or the fire department.

Therefore, in this case, since the telephone line 3 is not connected to a telephone such as a police station or a fire station, the control circuit 5 first drives the emergency call circuit 12 to call a subscriber such as the police station or the fire station. Send a signal. When a response signal is received from the police or fire department, the emergency message sending circuit 13 is driven to send an emergency message.

When the control circuit 5 is still unable to receive the dial tone signal through the alarm circuit 4 after the relay A14 has been deactivated and operated a predetermined number of times, the general telephone 2 calls a subscriber such as a police station or a fire station. It can be presumed that Therefore,
In this case, since the telephone line 3 is calling a telephone such as a police station or a fire station, the control circuit 5 does not drive the emergency calling circuit 12 but forcibly drives the emergency message sending circuit 13 to send the emergency message. To do.

Generally, the emergency call device 1 is obliged to install a call back telephone 7, and if the emergency call device 1 is activated after the general telephone 2 calls the police or fire department through the telephone line 3 once. Even if the alarm circuit 4 of the emergency call device 1 operates, the exchange cannot be restored unless the police, fire station, etc., as described above, so the telephone line 3 cannot be disconnected and the relay A1
When 4 is restored, the call back telephone 7 can be called from the police or fire department. That is, when the emergency notification device 1 is activated, not only the contacts a1 and a2 of the relay A14 are closed but also the contacts b1 and b2 of the relay B15 are closed. Then, when the relay A14 is maintained in the operating state and the relay A14 is restored, the call back telephone 7 can be called from the police or the fire department.

Referring to FIG. 2, an emergency call device 1 according to a second embodiment of the present invention has the same configuration as the emergency call device of FIG. 1 except as described below.

The emergency call device 1 of FIG. 2 determines whether or not the destination number corresponding to the dial signal and the special destination number described above match when the dial signal is sent from the ordinary telephone 2 to the telephone line 3. In the case of, the discriminator circuit 11 sends out a coincidence signal and maintains the coincidence signal until the general telephone 2 goes on hook, and when the emergency signal is received from the sensor 8,
A relay drive signal for operating the relays A14 and B15 is sent, and if there is the coincidence signal from the discrimination circuit 11, the message transmission circuit 13 is forcibly driven. If there is no coincidence signal, the dial tone is sent. The control circuit 5 drives the emergency calling circuit 12 after waiting for the detection of a signal.

The operation of the emergency notification device 1 of the present invention will be described.

The emergency notification device 1 monitors a dial signal for calling the outside from the ordinary telephone 2. Specifically, the determination circuit 11
Monitors the contents of the DP dial counter 9 when the general telephone 2 is a dial type, and monitors the contents of the PB receiver 10 when the general telephone 2 is a push button (PB) type. The discriminating circuit 11 uses the special number of the police or fire department, etc., in which the destination number corresponding to the dial signal indicated by the contents of the DP dial counter 9 or the PB receiver 10 is stored in advance in a built-in memory (not shown). It is determined whether the destination number of the subscriber matches, and the match signal is maintained until the general telephone 2 goes off-hook.

When the control circuit 5 receives the emergency signal from the sensor 8,
While sending the relay drive signal to the relay A14 and the relay B15, if there is the coincidence signal from the determination circuit 11, the emergency message sending circuit 13 is forcibly driven, and the emergency message is sent via the relay contacts a1 and a2. To the telephone line 3 and notify the police or fire department connected to the telephone line 3.

When there is no coincidence signal, when the control circuit 5 receives the dial tone signal through the notification circuit 4, it drives the emergency calling circuit 12 and sends out the calling signal to subscribers such as police and fire departments. When receiving a response signal from a subscriber such as the police or fire department, the emergency notification message sending circuit 13 is driven to send the emergency notification message to the police or the fire department.
