Indoor fire hydrants are the main facilities for fighting indoor fires in buildings.

They are one of the earliest and most common fire-fighting facilities in my country and are widely used in firefighting due to their reliable performance and low cost.

An indoor fire hydrant is an interface with a valve that supplies water to the fire scene from the indoor fire hydrant water supply network. It is connected to the indoor fire water supply pipeline and is a fixed fire-fighting facility in the building.

The components inside the indoor fire hydrant box include fire hoses, water guns, valves, and fire hydrant alarm buttons. Some fire hydrant boxes will be equipped with fire hose reels (portable fire hoses) and fire extinguishers.
