Description

Firefighting device equipped with smoke detection function that enables rapid fire suppression}

The present invention relates to a firefighting device equipped with a smoke detection function capable of rapidly extinguishing a fire.

Harmful smoke generated by a fire in a building or train is moved to the ceiling of a building or train by convection and then spreads along the ceiling at a high speed, which causes toxic smoke rather than damage caused by burns in an actual fire. The damage caused by suffocation is overwhelmingly high.

Therefore, smoke control facilities are separately installed in buildings, separated from firewalls that prevent fire from spreading, and these common smoke control facilities are usually installed on the ceiling and have a smoke control boundary wall that prevents the spread of smoke generated in the event of a fire for a certain period of time. form the mainstream
