Different Types of Fire Sprinkler Systems

Posted by: Krish Malhotra

Fire protection is critical in commercial buildings in case of fire or smoke. Installing a fire sprinkler system is the best preventative measure to take for the safety of your family and buildings. Below, there are four main types of fire sprinkler systems and their descriptions listed. Each and every building is unique, therefore the need for different types of sprinkler systems arises based on a building’s structure and inhabitants.

Wet Pipe Fire Sprinkler Systems –

As the name suggests, the wet pipe fire sprinkler system is the most common type of fire sprinkler system in use.This type of fire sprinkler system is filled with water, which allows a quick reaction to a fire. The water in the pipes attached to the sprinklers discharges quickly as a result of heat from a fire. High-rises or commercial buildings with more than one floor are where wet pipe sprinkler systems are most commonly installed. Due to the nature of the installation and components, the wet fire sprinkler system is typically low maintenance and the most cost-efficient for owners.

A pre-action sprinkler system is related to a deluge sprinkler system, but the sprinklers in this system are closed. This type of systemis best suited for the areas containing high-value types of equipment or contents and locations that are highly sensitive to the effects of sudden sprinkler water discharge. The pre-action pipe is frequently closed and is operated by a separate detection system.Water will not flow from the fire sprinklers until heat stimulates the operating component in each individual sprinklers.

Dry pipe sprinkler system-

Dry-pipe fire sprinkler systemsare used in structures that can have drastic temperature changes, such as freezing. Thesystem is filled with pressurized air in the pipes, which exits before water makes its way to the sprinkler heads. The systems are constructed this way so that thepipes do not freeze during colder temperatures when buildings are not equipped with adequate heating. This type of fire sprinkler system has a fast opening device to get rid of the pressurized air inside and speed up the flow of water to the sprinklers.


 A deluge system is a sprinkler system operating open sprinklers that are attached to a piping system connected to a water supply through a valve opened by the operation of a detection system installed in the same areas as the sprinklers. When this pipe opens, water flows into the piping system and discharges from all sprinklers. Deluge systems are used where large quantities of water are required immediately to control a fast-developing fire. Deluge pipes can be electrically operated.

Why are there so many options?

Each type of fire sprinkler systemexplained here is suited for various purposes, so it is essential to select the right system for each building, structure, or residential home.
