The present invention relates to an emergency alarm device, and more particularly, to an alarm device that prevents theft accidents in financial institutions and displays texts and alarms for a certain period of time, and then displays an indicator light.

In order to achieve the purpose of the present invention as described above, if an abnormality occurs in the extension line, as well as an external safe or a safe, the contents of the accident are displayed in text and an alarm sound is issued. Is to end.

In accordance with the already registered utility model No. 14763 of the present invention, the relay is installed in the transmitting device, and the relay is operated by connecting the DC power to another relay at the relay contact point by the transmitting switch, and the relay is also installed in the receiving device. The buzzer is designed to generate a cracking sound or a continuous sound so that the guard can cope with the accident.

In the conventional alarm system, when the wire connected between the transmitter and receiver is disconnected or shorted, the receiver does not operate in the receiver or the signal and the line fault are displayed in the same state, resulting in confusion. It became.

The present invention is designed to prevent line failure on the receiving device side when the wire is cut or struck when an error occurs in the wire where the signal generator is installed, for example, between a financial institution such as a bank and a security office such as a police box. It indicates the failure in the signal generator, which is a transmitter, in a letter, and restores the line immediately. The invention is described in detail according to the accompanying drawings as follows.

1 is a block diagram for explaining the present invention, and the output of the internal sensing circuit 1 is connected to be input to the hard bell driving circuit 4, the police box signal driving circuit 5 and the control circuit 6, and the external sensing is performed. The output of the circuit 2 is connected to the control circuit 6 and the safe box detection circuit 3 is connected to the police box signal driving circuit 4 and also the control circuit 6 via a switch SW. In addition, the output of the control circuit 6 is sent to the alarm sound generating circuit 11 and the timer circuit 8, and after a certain time by the timer circuit 8, the movable terminal of the automatic switching device 7 is closed. Switching is made from the furnace 10 side to the lamp driving circuit 9 side.

In the above-described configuration, the control circuit 6 of the police box signal driving circuit 5 turns on the subtitle display bulb when the switch installed in the internal, external, or safe box is turned off to notify the contents of the accident. . After a certain time has elapsed by the timer circuit 8, the operating terminal of the automatic switching device 7 is switched from the caption lamp driving circuit 10 to the lamp driving circuit 9, which is an alarm lamp, to indicate the cause of the accident. Will be done.

In addition, each sensing circuit is composed of a relay and a transistor or an integrated circuit, and an alarm switch is installed between input terminals of each sensing circuit to operate by turning on or off such a switch. In the same room and the input terminal of the outside detection circuit can be configured to operate when an error occurs in the track by attaching and connecting the alarm of the police box. In addition, the output of the control circuit 6 may cause all letters to appear simultaneously when the timer circuit 8 is activated and the subtitle lamp circuit 10 is powered to turn on the subtitles. Of course, it may be blinking or letters may be displayed one by one.

2 shows an example of the police box signal driving circuit 5, in which (a) and (b) change the polarity of the electrodes between the terminals in a relay manner.

That is, that in case of trouble, the operation to receive a start signal from the station detection circuit (1) or the safe detection circuit 3, the line (L ₁ , L ₂ The relay Ry, which received the start signal from the electrode of the ground, is grounded by the relay terminals RL ₁ and RL ₂ , thereby providing a line L _1. , L ₂ Drive by changing the polarity.

In addition, (c) and (d) illustrate an integrated circuit method, and a cruss (+) power supply shows a case in which the switch (R) is turned off because the resistor (R) and the switch are connected in series.

That is, the signal is connected to the lines L ₁ , A between the two ends of the ANLOG switch (A ₁ , A ₂ ) and the ANLOG switch (A ₃ , A ₄ ) with the NOT cable (NOT ₁ ) and NOT cable (NOT ₂ ) connected in series. L ₂ ) is connected, and between NOT gate (NOT ₁ ) and NOT gate (NOT ₂ ) is the control terminal of ANLOG (A ₂ , A ₃ ), and the output of NOT gate (NOT ₂ ) is ANLOG (A ₁ , When connecting to the control terminal of A ₂ ) Normally, the output of the NOT gate (NOT ₁ ) is Low and the output of the NOT gate (NOT ₂ ) is high (+) and the line (L ₁ ) L ₂ ) has a negative polarity and is powered by a signal. If the connection between and earth is not possible, the output of NOT gate (NOT ₁ ) will be high and the output of simultaneous NOT gate (NOT ₂ ) will be low, so that ANLOG (A ₁ , A ₂ ) is ON as shown in (d) OFF at the ANLOG (A ₂ , A ₃ ) is turned OFF when the line (L ₁ ) from plus to minus, and the line (L ₂ ) from minus to plus so that the polarity of the electrode can be operated. do.

For example, the character display method can light up the lamp installed behind the letter “Internal operation” and the lamp installed after the subtitle of other necessary characters such as “Check out the box outside the box” or “Check the door opening / closing abnormality” You can turn on to make the corresponding letter appear so that you can take action.

In the above case, if the letters are displayed by several lamps, the lamps can be identified even if one or two lamps are broken. When there is no manager, the lamps with high alarm sound and high power consumption are automatically turned off. to be.

In addition, three signals can be identified by changing the polarity of the line. For example, the track (L ₁ ) is a normal signal when the plus line (L ₂ ) is negative, the outgoing signal when the line (L ₁ ) is negative, and the line (L ₂ ) is positive, and when the line status is faulty (one line break, Mass production disconnection, 2-wire short-circuit, etc.)

3 is a circuit diagram of an exemplary embodiment of the present invention, wherein the AC power is regulated by a power transformer PT, and is full-wave rectified by a bridge rectifier circuit composed of diodes D _1-4 so that a zener diode ZD and an NPN transistor Q _It is to supply power to each circuit based on the constant voltage circuit of _1-4 ), and to connect the battery (BATT) in case of an AC power failure.
