Fire Sprinkler System Design

Fire sprinkler systems serve a great purpose of preventing fire damage in commercial buildings and households. Different types of fire sprinkler system design are available, each of which has varying working techniques. Choosing the best fire sprinkler system means designing a system of fire suppression that suits your needs and covers every angle of safety in terms of fire hazards and building code.

The potential benefits of installing and maintaining a fire sprinkler design are various; some are below.

  • Safety from physical injuries
  • Security of property from fire damages
  • Corporate security
  • Confident workers in fire hazardous places
  • A good reputation in terms of responsibilities as a landlord and industrial or commercial building owner

Here are a few things to keep in mind when designing a fire sprinkler system.

Main Types of Fire Sprinkler Systems

Dry Pipe

This type of fire system operates slowly and needs thorough maintenance. For spaces such as warehouses, garages, and any other unheated places or spaces, “dry pipe” fire systems are the best. They have compressed air inside the pipes. Using numerous supply systems such as nitrogen bottles, electronic air compressors, this system lets out the air upon activation. This leads to a pressurized release of water, which extinguishes the fire.

Wet Pipe

Easy to install and maintain, this system of fire sprinklers contains water in the pipes at all times. Contrary to popular belief, water release can be simultaneous. This is the most common type of fire system in heated spaces.


This type of fire sprinkler system has applications like places containing highly combustible and flammable components. These spaces may serve storage or operational purposes. With all sprinkler heads open at all times, a signal from an individual device such as a heat sensor or a smoke sensor triggers the release of water.

Fire Sprinkler System Design: Water Supply

Fire sprinkler systems heavily rely on the quality and quantity of water supply. Water is the main component for extinguishing and restricting the spread of fire. NFPA requires you to have an automatic water supply in the fire sprinkler system.

This ensures an uninterrupted supply of water and with no human interference. The need for professional engineers and designers is paramount. The sources for water supply can vary and include reservoirs, pools, water towers, ponds, or gravity tanks. Each type of water supply requires proper calculations pertaining to the capacity and the flow. These calculations determine how much water can flow from the source and the pressure it can generate.

Thus, it helps to accurately select and place pipes to ensure a safe and operable fire sprinkler system design. Calculations relate to flow test, for which the formula is as such:

Q=29.83 x C x d2 x

The foundation of fire sprinkler design lies in the water supply. Thus, a careful analysis of this factor is a must.

Buildings that Require Fire Sprinkler Systems

The next step in designing a fire sprinkler system is to know the building type. Whether it is a commercial, industrial, or residential building will help to determine the best fire sprinkler design.

The designers of the fire sprinkler system will cooperate alongside engineers and architects to draft out a fire sprinkler design. The final blueprint will be in accordance with NFPA rules and codes. The most common type of NFPA standard in use for designing a fire sprinkler system is the NFPA13.

Other Factors

Occupancy hazard is another factor. This helps measure the level of hazards that potentially exist. The amount of energy capable of releasing in the case of fires determines how much water is needed. This makes it easier to design the fire system. The products and components present in the building are subject to the term “occupancy hazard.”

Further, the area of design also matters. The level and positioning of the building can make it difficult to supply water to all sprinkler heads at once. Therefore, considering the worst-case scenario helps in identifying any potential hindrances that can occur in the operation of the fire sprinkler system.
