2. Description of the Related Art In recent years, multi-family apartments have occupied the center of the form of living in cities.
A fire monitoring and alarm system has been introduced to ensure a safe and comfortable life. In such a fire monitoring and alarm system, a fire detector, a gas detector, and even a human body detector installed in each dwelling unit or common area are connected to a fire receiver. After receiving the alarm from the device, check whether a fire has actually occurred,
Fire alarms are set for all dwelling units or related dwelling units.

[0003] It is necessary to confirm such an alert,
Fire detectors, etc., are certain indicators of fire, for example, because they detect the occurrence of smoke and determine that a fire has occurred, so smoke is generated even if it is not an actual fire. As long as the alarm is issued, so-called false alarms are also included, and it is impossible to judge whether it is an actual fire or not by the first alarm. Many of you may have experienced fire alarms and the sound of a fire alarm bell with tobacco smoke.

[0004] For this reason, conventionally, for example, various methods have been proposed for confirming whether a fire alarm is caused by an actual fire or not.
One method is to check the alarm again after a certain period of time after the first alarm is issued, and to judge that a fire has actually occurred if the sensing alarm continues. Another method is to provide a smoke detection level and determine that a fire has actually occurred when a predetermined level is reached. Various other methods have been proposed according to the sensing target.

[0005]

As described above, in the above-described conventional fire monitoring and alarm system, various efforts have been made to eliminate false alarms from the detectors, and the results thereof have been utilized. However, in the past, there was a warning from the sensor, and after confirming the above, only when it was confirmed that there was a fire, the information about the warning was recorded and saved. No information about the alert was recorded. Also, even if the record of the alarm is left,
It was not left as information that it was so-called misinformation.

However, in this case, valuable information included in the trouble report is not utilized. In other words, there are some reasons for false alarms to occur, for example,
This is because there are causes such as sensor malfunction, incomplete operation, poor installation location, and environmental impact of the installation location, and the occurrence of false alarms indicates that such a cause exists. It is.
