The stopper, which is located at the portion, is released in a form in which the held stopper is angularly displaced upward by the spring force of the spring, and the plunger located inside the selection valve is maintained in the operation standby state. By releasing the stopper in this manner, the compressed gas for opening the plunger provided in the main body of the selection valve in an operation standby state is discharged to one side of the actuator and its guide hose. And actuate the actuator provided at the top of the fire extinguishing gas container to open the passage for the main fire extinguishing gas, which is collected and reused, or released to the atmosphere in the case of harmless gas. You. When the fire extinguishing gas passage is opened by the valve opening compressed gas, the fire extinguishing gas moves through the pipeline to reach the lower part of the selection valve, and the plunger in the released state is released by the gas pressure.

In the unlikely event that the intended use is for a fire that may occur in the building, it is not used periodically or on a daily basis as in other facilities of the building. Due to the limited time of the fires that occur, the aging is relatively fast, and the frequency of occurrence of electrical and electromagnetic defects due to aging is high even when periodic maintenance and inspections are performed.

The lack of sound increases casualties, leaving small fires that can be extinguished early, leading to immediate fires, resulting in precious lives and property damage. . The deficiencies of the fire prevention and fire suppression facilities can ultimately be attributed to the lack of audible alarms operating on electrical and electromagnetic systems and the inactivation of selection valves.

There is no particular problem for the fire extinguishing gas to move and bleed through. However, since there is no alarm device that can sound an alarm and evacuate residents, fire extinguishing gas is blown out and the number of casualties increases even though residents have not yet evacuated. There is a big problem of doing it.

Therefore, the residents who could not be evacuated will have difficulty breathing and convulsions due to the fire extinguishing gas together with the smoke generated at the time of the fire, thereby choking.
There is a problem that it is more important than the fire extinguishing work of the building and also leads to an increase in casualties.
