Description

[Detailed Description of the Invention] Technical Field> The present invention utilizes weak radio waves to send external notifications through telephone lines that issue alarms based on abnormality detection signals installed in various parts of the house, thereby providing comprehensive information about the inside of the house. This relates to alarm devices for disaster prevention, crime prevention, etc.0 <Prior art> In conventional alarm devices of this type, intruders often break in by cutting telephone lines or electrical service lines; When disconnecting, the base unit can be operated by connecting a well-known backup device (battery) to the base unit, and the power source for transmitters such as intrusion transmitters and fire transmitters is There is no problem because of the battery, but if the telephone line is disconnected, external notification cannot be made through the telephone line, and there is a drawback that it is not possible to warn that the telephone line has been disconnected.

Purpose of the present invention An object of the present invention is to provide an alarm device that eliminates the above-mentioned drawbacks.

<Embodiment> An embodiment of the alarm device of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the alarm system of the present invention. In FIG. A fire transmitter that transmits an abnormality detection signal to the main unit 3 by radio waves when detected; 4 is an intrusion sensor that detects the opening and closing of doors 5 and windows 6 to detect an intrusion abnormality; 7 is an intrusion sensor 4 that detects an intrusion abnormality; An intrusion transmitter that transmits an abnormality detection signal to the base unit 3 by radio waves when detected; 8 is a gas sensor that detects gas leak; 9 is an intrusion transmitter that transmits an abnormality detection signal to the base unit 3 by radio waves when the gas sensor 8 detects a gas abnormality; A gas transmitter for transmitting data, 10 a water leak sensor for detecting water leaks, and a water leak transmitter for transmitting an abnormality detection signal to the base unit 3 by radio waves when the water leak sensor 10 detects a water leak abnormality in 1 summer; 12 is a bath sensor that monitors the water level and temperature of the bath; +3 is a bath transmitter that transmits a detection signal to the base unit 3 by radio wave when the bath sensor 12 detects a set water level, set temperature, or abnormality; Fire sensor 1 and fire transmitter 2. The intrusion sensor 4 and the intrusion transmitter 7. The gas sensor 8 and gas transmitter 9. The water leak sensor 10 and the water leak transmitter 11. The bath sensor 12 and bath transmitter 13 are each connected by wire.

The base unit 3 is the fire transmitter 2. Intrusion transmitter 7° gas transmitter 9. Water leak transmitter 11. An alarm is issued in response to a detection signal transmitted from the bath transmitter 13, an abnormal state display lamp 4 is turned on, and an external bell 15 is connected by wire to notify outside the house. It also transmits a signal to the handset 17 via the power line 16. The handset 17 that has received the signal also issues an alarm in accordance with the detection signal.

That is, if the slave unit +7 is installed at a location separate from the base unit 3, the slave unit 17 can also be notified when an abnormality occurs. Furthermore, the base unit 3 and the slave unit +7 also have the function of inter-7 on-call via the power line.

The base unit 3 is connected to a telephone 18. The telephone 11
j: Has sensor input terminals for intrusion, fire, gas leak, etc.
A reporting destination can be set in advance, and when an abnormality signal is input from the base unit 3 to the sensor input terminal of the telephone 18, an automatic notification is sent to the reporting destination via the telephone line 19. 20 is the electrical service line j.

FIG. 2 is a block diagram showing an embodiment of the alarm device of the present invention. In FIG. Display unit 24 consisting of an LED and a clock display section for displaying abnormal conditions. A carrier circuit 251 that sends and receives audio and signals to and from the handset 17. A speaker 26 that issues calls and alarms. microphone 27
1 Call circuit 281 Function buttons 29 for setting the time, stopping alarms, etc. In the event of an intrusion or fire, the abnormal condition will be reported to your phone! an abnormal state signal output section 30 for outputting to 8; Detection circuit 31 that detects whether the telephone line 19 is disconnected
, and each is controlled by a control circuit 32.

The telephone 18 is connected to the abnormal state signal output section 30 and the sensor input terminal 33 of the base unit 3, and when an abnormal signal is input from the base unit 3 to the sensor input terminal 83 of the telephone t8, it is automatically sent to the notification destination via the telephone line I9. This is for reporting.

The telephone 18 also has a ringer circuit 35 that generates a ringing tone when a 16 Hz, 75 V AC signal is applied, a dial circuit 37 that generates a signal when a dial button 36 is operated, and a dial circuit 37 that is superimposed on the telephone line 19. A telephone call circuit 88 that separates and amplifies the received voice and outputs it. A handset 39 that has a built-in microphone and receiver. A display unit 401 that displays a dial number when the dial button 36 is operated.
Function buttons 41 used when setting notification destinations, speed dialing, etc. It consists of sensor input terminals 33, each controlled by a control circuit 42.

Since a telephone call is made on the telephone line I9 by inverting the calling pulse and the polarity of the telephone circuit ■O, the detection circuit 31
i If the level is not detected for a certain period of time, the control/circuit 3
An abnormal condition is output to the speaker 26, and an alarm sound is to be sounded from the speaker 26.0 Figure 3 is a block diagram of a telephone equipped with a telephone line disconnection detection terminal.In Figure 3, the telephone line 19 is disconnected. When detected, the detection circuit 43. The disconnected state is outputted to the detection terminal 45 via the control circuit 44.

When the telephone line 19 is disconnected, the output of the detection terminal 45 is maintained by the backup battery 46 connected to the control circuit 44.

When the telephone line 19 is disconnected as described above, the base unit 3
and handset 17. External bell! This is to prevent intrusion by issuing an alarm at 5 etc.

In this case, the base unit 3 is equipped with a backup device (
Since the battery) 47 is connected, the electric lead-in line 2
It works even if 0 is disconnected. Also, intrusion transmitter 7. No problem will occur because the power supply is for the transmitter handsets such as the fire transmitter 2.

Effects> Since the alarm device of the present invention has the above-described configuration, when the telephone line is disconnected, the base unit or slave unit issues an alarm to prevent intrusion.
