fire sprinkler system


A fire sprinkler system is a device that discharged water. It is an active fire protection method, that includes the water supply system, providing adequate pressure by flowing water, distributing the piping system in which the sprinklers are connected. In most cases, a fire sprinkler system can prevent property damage and reduce the risks of injuries to the occupants of the premises.

Fire sprinklers are extensively used worldwide; this is proved by over 40 million devices are being installed each year. 96% of the fire in buildings is being controlled and protected by the fire sprinkler system. The device is being installed in ceilings or sidewalls.

In this article, we will learn the types of fire sprinkler systems:

1.    Wet pipe

It is the most common type in residential buildings. They are also the most reliable because they are simple. This is how they work; cold water is stored under pressure in the pipes and when a certain point of heat is reached, the water is being discharged by the fire sprinkler system.

2.    Dry pipe



This system takes slightly a little longer to be activated. Most of the systems are being used in unoccupied or unheated buildings where pipes may freeze and explode. Some advantageous for the protection of valuable collection and other water sensitive areas.

3.    Deluge


Typically, this type is being used in areas where rapid-fire is a major concern such as loading bays, warehouses, and high-rise buildings. The nozzle is always open, based on the system. Activation of a fire alarm initiating device which in turn signals the deluge valve to open, allowing water to enter the piping system. Water flows from all sprinklers simultaneously.

4.    Pre-action


Pre-action sprinkler systems are a combination of wet and dry pipe systems, typically used in areas at high risk of water damage. The systems are specialized for use in locations where accidental activation is especially undesirable, such as in museums with rare artworks, manuscripts, or books; and data centers, for protection of computer equipment from accidental water discharge.

5. Foam

Foam water sprinkler system kind discharges a mixture of water and foam concentrate if activated. They are generally used in case of high challenge fires, such as in the presence of flammable liquids. The foam can be inserted in any of the systems described above.


6. A water spray

Water spray systems are identical to deluge systems but, unlike the latter, the first is designed to safeguard a uniquely configured hazard (so they don’t cover all the horizontal floor area of space). Electrical transformers, for example, are usually protected by a water spray system.

7. Water mist

A water mist system is typically used in conditions where water may damage things or in case of minimal water supplies. They are provided with a heat absorbent vapor and operate as a wet pipe, deluge, dry pipe or pre-action system. In this case, compressed gas is used to atomize the water, so it turns into a mist.

In a nutshell, everyone should invest in a fire protection system, especially fire sprinklers. This is because the device is certainly a great choice for most buildings. With a sprinkler system, you can be guaranteed total protection against fire emergencies since they are famous for minimizing damage and prevent loss of life.
