How does a suspended fire extinguisher become a safety guardian of building space?

In house construction, suspended fire extinguishers are suspended from the roof in an inverted manner, and together with the rain sprinkler system, a safety protection network is established. This special fire-fighting device is usually installed in large spaces such as warehouses, parking lots, and shopping malls. Its cylindrical metal shell is loaded with dry powder or gas fire extinguishing agents and is an indispensable part of the building fire protection system.

When a fire occurs, the ambient temperature rises sharply to the set threshold, and the temperature-sensitive glass bubble at the top of the device breaks immediately, triggering the internal pressure release device. This automatic start-up method does not require human intervention. With its fast-response fire extinguishing mechanism, the suspended fire extinguisher sprays downward evenly in an umbrella-shaped form to form a protection area. Compared with traditional handheld fire extinguishers, this top-down fire extinguishing method can break through obstacles and achieve no-dead-angle coverage of three-dimensional space, which is suitable for large places where precision equipment is stored.

The coordination between the suspended fire extinguisher and the rain sprinkler system is another major technical highlight. When the fire detector captures an abnormal signal, the suspended fire extinguisher releases fire extinguishing agent to suppress the fire, and the sprinkler system that is activated almost simultaneously forms a secondary protection through a dense water curtain. This dual fire extinguishing system overcomes the possible response delay of a single system, and can improve the fire extinguishing efficiency through the effects of dry powder asphyxiation and water curtain cooling. Under special circumstances, the suspended fire extinguisher array can form a chain reaction. When a unit is activated, the adjacent devices are activated in groups through pressure conduction, building a dynamically expanded fire extinguishing line.
