されている。In such a fire gas leak alarm, as a gas detector, it is only necessary to detect a city gas or carbon monoxide to issue an alarm, but as a fire detector, a smoke caused by a fire is detected. There are smoke detectors, heat detectors that detect heat from fire, etc.For example, it is proposed to use heat detectors with less false alarms for kitchens that emit smoke or water vapor from cooking, such as living rooms and bedrooms For places with little fire, it has been proposed to use smoke detection with good detection performance.

報は、単一の警報および各警報の組み合わされた複合型
の警報が存在するが、このような警報だけでは、ガス漏
れや火災の緊急度が分からないという問題がある。However, in the above-mentioned conventional fire gas leak alarm, the alarm by sound includes a single alarm and a compound alarm in which each alarm is combined. There is a problem that the urgency of a gas leak or fire cannot be determined only by such an alarm.
【０００６】また、音声警報のレベルが小さいものであ
ると、人が火災ガス漏れ警報器の設置場所から離れたと
ころにいるときには、緊急度を要する警報を聞き逃すお
それがある。If the level of the sound alarm is low, there is a possibility that when a person is away from the place where the fire gas leak alarm is installed, a warning requiring urgency may be missed.
【０００７】更に、一般に火災ガス漏れ警報器は住宅用

警報が聞き取れるようにすることが望まれる。Furthermore, fire gas leak alarms are generally used for houses, and it is desired that an alarm can be heard even by an elderly person or a hearing-impaired person.

させているものではない（特開平１１−３２８５５３号
公報参照）。Conventionally, there has been proposed a fire alarm which changes the volume of a buzzer or temporarily increases a warning sound in accordance with a change in smoke density or temperature. However, such a fire alarm has a simple smoke alarm. It merely changes the volume according to the values of the density and the temperature, and does not change the warning sound from the viewpoint of the degree of urgency (see JP-A-11-328553).
【０００９】一方、常に警報音量を非常に大きなものと

ないという問題がある。On the other hand, it is conceivable that the alarm volume is always set to a very high level so that the alarm sounds throughout the house. When a warning is issued, the problem is not only to surprise the residents, but also to turn off the power of the fire gas alarm device, making it impossible to warn of a real fire or gas leak. Further, in general, once an alarm is generated, even if a more urgent condition is detected, a new emergency condition is not reported because there is no means for newly reporting it. is there.

とめると表１の通りとなる。That is, in this example, it is determined that, for example, an alarm in which fire and CO are combined is less likely to be a false alarm and has a higher degree of urgency than an alarm with only CO. When all three alarms are issued, the urgency is highest. When each of the detectors does not detect any fire or gas, the normal monitoring state is continued. Table 1 summarizes the above determination processing.

断部にて判断してもよい。The above example is merely an example of setting the urgency level. As another embodiment, for example, if at least one of the fire sensor and the plurality of gas sensors exceeds the threshold value, the output values of the other sensors at the same time are simultaneously referred to, and the output values of the other sensors approach the threshold value. If it is, the emergency level 2 may be determined by the warning determination unit.

圧レベルは適宜変更することができる。Then, upon receiving the value of the urgency level from the alarm judging section 20, the voice control section 24 outputs a warning sound as a synthesized voice, and the volume adjusting section 25 adjusts the volume. In this case, in this example, the warning sound may be, for example, either a buzzer sound or a synthesized voice, but for example, the output sound pressure is set to the following three levels according to the urgency level. Note that this sound pressure level can be appropriately changed.
【００３３】緊急度レベル１：７０ｄＢ 緊急度レベル２：７５ｄＢ 緊急度レベル３：８０ｄＢUrgency level 1: 70 dB Urgency level 2: 75 dB Urgency level 3: 80 dB

Please check immediately. Further, it is desirable to change the sound pressure level and sound quality together with the content of the synthesized voice.
【００３６】これにより、緊急度が高い場合には大きな

However, the urgency level is determined based on the temperature rise rate, the gas concentration rise rate, and the like. And the content of the notification can be changed according to the detected content. The setting of the urgency level is not limited to the above example, and may be changed according to the installation environment. Further, the urgency level once set may be changed afterward.

ことができるという効果を奏する。As described above, according to the fire gas leak alarm according to the present invention, the emergency level is determined based on the output content of the detecting section. Since the content of the voice alarm is changed according to the degree of urgency, the higher the urgency level is, the easier the voice alarm is to hear and the more accurate and prompt the emergency situation can be recognized, and the more appropriate action should be taken promptly. It has the effect of being able to do so.

ことができる。According to the second aspect of the present invention, since the volume of the voice alert increases as the urgency increases, the urgency is low, that is, when there is a high possibility that there is no accidental fire or gas leak. In the case where both a fire detection and a gas leak detection are detected at a low volume, that is, when there is a high possibility of an actual fire, a high volume alarm is issued, and the alarm can be reliably notified.
