業性が低下したりする問題点があった。However, according to the above-described conventional alarm device inspection tool, for example, when it is desired to perform an operational inspection of the city gas alarm device and the carbon monoxide gas alarm device, the city gas alarm device is used as the alarm device. It is necessary to separately prepare a city gas alarm inspection tool that supplies carbon monoxide gas to the alarm device and a carbon monoxide gas alarm inspection tool that supplies carbon monoxide gas to the alarm device. There was a problem of low efficiency. When inspecting a heat detection type fire alarm, a high heat source is brought near the fire alarm to inspect the fire. If you put the alarm device too close to the alarm device, the housing of the alarm device may be scorched or deformed, but if you try to check it while keeping it away, there is a problem that the inspection workability deteriorates. .

Therefore, with the development of such an alarm device, an inspection tool capable of efficiently inspecting such an alarm device is desired.

たものであることが好ましい。To achieve this object, the alarm checker according to the present invention is characterized in that a fuel gas supply section is provided, and the fuel supplied from the fuel gas supply section through the fuel gas supply path. It has a burner section provided with a burner nozzle for burning gas, and a guide nozzle for guiding the inspection gas generated by the combustion of the fuel gas to the detection section of the composite alarm device,
In a longitudinal side view in a state where the guide nozzle is mounted on the burner nozzle, a point where a heat radiating portion capable of discharging heat generated in the guide nozzle is provided at a portion of the guide nozzle closer to the tip than the burner nozzle. It is in. Further, it is preferable that the burner section is provided with a gas combustion catalyst section for adjusting an incomplete combustion gas amount in the inspection gas, and the gas combustion catalyst section has a flow rate of 0.06 to 0.
5 to the butane gas burned at 13 g / min
It is preferable to provide 5 to 10 mg of a 10 wt% Pt-supported Al 2 O 3 catalyst.

ガスを生成させることができる。[Operation and Effect] That is, since the fuel gas supply unit is provided and the burner unit provided with the burner nozzle is provided, the fuel gas supplied from the fuel gas supply unit through the fuel gas supply passage is burned, and the burner nozzle is operated. In addition to carbon dioxide burned from the fuel gas, it is possible to generate an unburned fuel gas and an inspection gas having heat including carbon monoxide gas due to incomplete combustion.

ものであるか否かを確認することができる。Further, when the guide nozzle is provided, the inspection gas can be constructed so as to be generated in the guide nozzle, and the inspection gas can be guided to the detection portion of the composite alarm device. Therefore, when the inspection gas having heat reaches the gas detection element provided in the gas alarm or the detection unit provided with the heat-sensitive element of the heat detection type fire alarm, those alarms are activated. Therefore, it is possible to confirm whether or not the operation is normal.

供給に支障をきたしにくい。Since the inspection gas has heat, if the inspection gas is continuously supplied to the same place for a long time,
The place is highly heated, and there is a risk of burning or deforming as shown in the above-mentioned conventional technique. On the other hand, when the guide nozzle is provided with a heat radiating portion for releasing heat, the necessary minimum inspection gas and heat generated in the guide nozzle are supplied to the alarm device, and the surplus is different from the detection unit. It is possible to allow the heat to be released to a portion, and it is possible to prevent heat from being concentrated and concentrated on a specific location and reaching high heat. Further, the heat radiating portion is provided at a portion of the guide nozzle that is closer to the tip end side than the burner nozzle in a longitudinal side view in a state where the heat radiating portion is attached to the burner nozzle. In addition, it flows in a direction different from that of the alarm device, and moreover, it is less likely to interfere with the oxygen supply to the burner section.

が知られている。これらの状況を考慮した場合に、上述
のブタンガス濃度は、都市ガス警報器による警報を発生
できる濃度として十分であることがわかる。Further, when the burner section is provided with a gas combustion catalyst section for adjusting the amount of incomplete combustion gas in the inspection gas, the combustion of the fuel gas in the combustion section is made closer to complete combustion. The amount of heat generation can be increased and the amount of carbon monoxide gas generated by incomplete combustion can be reduced. Thereby, the composition of the inspection gas can be set to a gas composition, concentration, and temperature more suitable for inspection. Specifically, the gas combustion catalyst unit has a flow rate of 0.1.
5 to 1 for butane gas burned at 0 g / min
Since 5 to 10 mg of 0 wt% Pt-supported Al 2 O 3 catalyst is provided, the composition of the inspection gas that has passed through the catalyst combustion section becomes butane: 6000 to 8000 ppm CO: 400 to 800 ppm. The alarm generation setting of the city gas alarm is usually 3000 to 4000 ppm in terms of methane concentration,
Moreover, the output characteristics of the gas detection element for methane and butane are about the same. It is known that the output for butane becomes lower than the output for methane due to a filter or the like. When these situations are taken into consideration, it is understood that the above-mentioned butane gas concentration is sufficient as a concentration at which a town gas alarm can generate an alarm.

発生しない適切な濃度となっている。Further, in the case of a carbon monoxide gas alarm, since it is usually sensitive to carbon monoxide gas of 50 ppm, it is sufficient to generate carbon monoxide gas of 50 ppm or more. The carbon monoxide gas sensing element may take a long time for output response. Therefore, it can be said that the above-mentioned carbon monoxide concentration is a preferable concentration in order to shorten the inspection operation time. Moreover, even if a person inhales the inspection gas for a short time due to a malfunction, the concentration is appropriate so that no serious problem occurs.

It becomes a temperature that makes it hard to burn or burn.

性を向上させることができた。Therefore, it becomes possible to adjust the carbon monoxide gas, the combustible gas, and the inspection gas in which the heat is appropriately adjusted, and the alarm level of the normal carbon monoxide gas (incomplete combustion) alarm device can be easily adjusted. It can supply suitable inspection gas that can be inspected, such as carbon monoxide gas alarm, combustible gas (city gas, propane gas) alarm, gas leak alarm,
It will be applicable to any inspection of thermal fire alarms. In addition, these complex alarms can be inspected at once, and the convenience of inspection work can be improved.
