Claims (1)

[Claims for Utility Model Registration] 1. An alarm circuit 4 connected to a telephone line 3 and also connected to an emergency signal generator 8, which generates a dial tone from the telephone line 3 in response to generation of an emergency signal. an emergency call unit 12 that detects a signal and outputs a call signal for calling a subscriber with a special destination number such as the police or fire department; and in response to a response signal from the subscriber in response to the call signal, The alarm circuit 4 having a message sending unit 13 for sending an emergency message, the general telephone 2, and the telephone line 3.
In the emergency notification device, the switching section connects the telephone line 3 to the telephone 2 and the alarm circuit 4 when the switching section is not in operation, and connects the telephone line 3 to the telephone 2 when the telephone is in operation. telephone line 3
a relay 14 that connects the alarm circuit 4 to the alarm circuit 4; and when the emergency signal is received from the emergency signal generator 8, it sends out a relay drive signal that operates the relay 14; When the dial tone signal is received, the emergency call unit 12 is activated, and when the dial tone signal is not received, the relay 14 is activated after the relay 14 is deactivated and activated a predetermined number of times. An emergency notification device comprising: control means 5 forcibly driving the emergency message sending section 13 when the dial tone signal is not yet input. 2 An alarm circuit 4 connected to the telephone line 3 and also connected to the emergency signal generator 8, which detects a dial tone signal from the telephone line 3 in response to the occurrence of an emergency signal and alerts the police or fire department. an emergency calling unit 12 that outputs a calling signal for calling a subscriber with a special destination number such as a local office; and a message sending unit that sends an emergency message in response to a response signal from the subscriber in response to the calling signal. 13, the general telephone 2, and the telephone line 3.
In the emergency notification device, the switching section connects the telephone line 3 to the telephone 2 and the alarm circuit 4 when the switching section is not in operation, and connects the telephone line 3 to the telephone 2 when the telephone is in operation. telephone line 3
a relay 14 that connects to the alarm circuit 4; when a dial signal is sent from the telephone 2 to the telephone line 3, it is determined whether the destination number corresponding to the dial signal matches the special destination number; and a discrimination circuit 11 which sends out a matching signal when there is a match and maintains the matching signal until the telephone set 2 is turned on; and when the emergency signal is received from the emergency signal generator 8, the relay 14 is activated. In addition to sending out a relay drive signal, if there is a matching signal from the discrimination circuit 11, the message sending unit 13 is forcibly driven, and if there is no matching signal, it waits for the detection of the dial tone signal. , and a control means 5 for driving the emergency call section 12.
