As described above, the main controller 10 to which the gas detection output signal is applied in the state of storing the phone number and voice is controlled to generate an alarm sound and the corresponding LED to light through the notification unit 14, and at the same time, the telephone line ( 13) Call the phone number entered through 13) and transmit the prepared voice message three times repeatedly. For example, the restaurant gas alarm is on. The breaker is closed. The breaker is open.

At this time, if the other party is busy when the call line 13 is sent to the outside, if the call is connected to the next number and then try again. Link by number of rank. If there is no beep, it is indicated as a communication error (telephone line disconnection).

In particular, the transmission method is decided according to the type of the input number.If the input number is a pager, it sends the number (call code + situation occurrence code) input after connection, and the input number is a general phone or a mobile phone. After connection, it sends out (situation + breaker status) by voice. For example, the restaurant gas alarm is active (voice saved) and the breaker is open. On the other hand, if the input number is a PC, after the connection (situation code + breaker status) is transmitted as a code.

Therefore, even if the manager is not at the site, the gas situation information is constantly transmitted to the situation center (6) and the manager (7), which are the central monitoring devices, by means of the above-mentioned contact means, thereby preventing gas accidents in advance. .

In addition, the repeater as described above can check and control the status from the outside, first, by entering a specific code using the phone can check or close the current state of the breaker. For example, if you check the breaker status, the corresponding LED lights up when connected through the telephone line, and after you connect the telephone (code # 10), you can check the status of the breaker by voice message. Since it is always connected, situation information can be transmitted and stored (data exchange) with a specific code.

In this case, since a telephone line is used as a communication line, wherever there is a telephone line, a PC can be installed anywhere regardless of a place and region, so that a large number of repeaters can be managed in a large building or a factory in a large building. As a result, it is possible to build an integrated management system that can manage the history of alarm occurrence at each site using the data aggregated on the PC, or check the operation status and cope with any situation occurrence.

As described above, the present invention monitors the operation state of the gas alarm completely unattended and informs the manager or the situation center of the corresponding information using various communication devices (beep, phone, mobile phone, PC). As a system, the mobile installation is free, easy to use, and can immediately check for leaks and malfunctions, which greatly contributes to relieving gas users' anxiety, and can also control data using a PC or a telephone from the outside.
