Basic concepts of wall fire suppression systems

Wall fire suppression system is the most popular fire suppression system in residential as well as industrial projects. If you've ever seen red pipes leading around a building or factory, that's the firefighting piping system. In news clips about a fire, you may see a firefighter spraying a jet of water up to the 8th floor of a building or more, the system the firefighter uses is called a wall fire suppression system. The wall fire suppression system is so powerful that it can push water up to the 8th floor of the building, straight into the fire.

Is it always necessary to provide a fire protection system with a wall fire extinguishing system?

The wall fire suppression system forms the foundation of the fire protection system. Without the wall fire suppression system, a fire protection system cannot be called a true fire protection system. That would be a superficial system. For large spaces in general. The construction and installation of a wall fire suppression system is relatively simple.

Basic Concepts 

This is a very effective fire suppression system for a variety of construction types and buildings as well as commercial complexes. The system mainly includes water storage tanks (underground or surface), pump clusters, pipeline systems around the building, branch pipes, valves, faucets and fire fighting cabinets. On the main pipeline there are vertical fire fighting pillars with water intakes installed.

The system has two types: wet and dry. The wet system is an automatic system while the dry system is a system that can be operated manually.

In the event of a fire, the hose reels can be connected to the fire valve to spray water onto the fire causing the fire pump to operate. For automatic operation mode, the pressure compensation pump usually creates pressure for the pipeline, but as soon as the fire valve opens, the pipeline pressure will decrease and the main pumps will start automatically.

With the help of high pressure and abundant water, the water jet from the nozzle can spray into the base of the fire and extinguish it completely.

What is the function of the wall fire suppression system?

A special water tank is installed, called a fire water tank, which is always filled with water 365 days a year. This water tank is connected to the fire pump room. From the pump room, there are two or three main pipes. These pipes form a pipeline system around the building. The pump has the effect of filling water in the pipeline with a pressure from 7bar to 10bar.

When a person observes a fire, he will activate the wall fire suppression system and spray directly towards the fire. At that time a very strong stream of water will attack the fire and the fire will finally be extinguished. The pump will continue to run to maintain water pressure in the pipeline.

What are the advantages of wall fire suppression systems?

The wall fire suppression system is very powerful and can be effective for medium to large fires. The wall fire suppression system has a long range. Because they are installed throughout the entire structure, they can attack the fire from many different angles. The entire system requires low maintenance and is virtually leak-free. In addition, the wall fire suppression system also has a long lifespan.

The main pipe runs around The building is installed underground so it does not obstruct vehicles and does not cause any impact when a fire occurs.

• Other fire suppression systems such as automatic nozzles and foam systems can all be connected to the wall fire suppression system.

What are the limitations of wall fire suppression systems?

There are a few limitations in wall fire suppression systems. First, this system requires people to operate. The water jet at the nozzle is so powerful that two people are needed to hold the nozzle. In addition, this system may cause damage to tools and machinery.

Wall fire suppression systems are very popular and therefore many customers only look to units specializing in supplying and installing this system when they need to install a fire suppression system; But the important thing to understand is that a wall fire suppression system is not necessarily the most effective system for each type of project, because today there are many other automatic/semi-automatic fire suppression systems.
