5 Types of Fire Sprinklers to Consider for a Sprinkler Installation

Fire sprinkler systems are essential safety measures designed to protect lives and property in the event of a fire. These systems are designed to detect and extinguish fires automatically, providing a crucial line of defense against spreading flames.

In this article, we will discuss five different types of fire sprinkler systems commonly used today.

1. Wet Pipe Sprinkler Systems

Wet pipe sprinkler systems are the most common type of fire sprinkler system. They consist of a network of pipes filled with pressurised water. When a fire is detected, the heat activates the sprinkler heads, which release water onto the flames. Wet pipe systems are simple, reliable, and cost-effective, making them suitable for many buildings, including homes, offices, and retail spaces.

2. Dry Pipe Sprinkler Systems

Dry pipe sprinkler systems are typically used in areas where freezing temperatures are a concern. Instead of containing water, the pipes in these systems are filled with compressed air or nitrogen. When a fire occurs, a valve opens, releasing the air and allowing water to flow into the pipes. The water is then discharged through the sprinkler heads. Dry pipe systems are commonly found in unheated areas such as parking garages, warehouses, and outdoor spaces.

3. Pre-Action Sprinkler Systems

Pre-action sprinkler systems combine features of both wet and dry pipe systems. These systems require two triggers before water is released. Firstly, a fire detection system must detect a fire. Secondly, a sprinkler head must be activated. Only when both triggers are met does the pre-action valve open, allowing water to flow into the pipes and discharge through the sprinklers. Pre-action systems are suitable for areas with high-value assets that need protection against accidental water discharge, such as data centers, museums, and art galleries.

4. Deluge Sprinkler Systems

Deluge sprinkler systems are primarily used in high-hazard areas where rapid fire suppression is necessary. These systems involve open sprinkler heads that are constantly open, allowing water to flow freely. When a fire is detected, a detection system triggers a deluge valve, simultaneously releasing a large volume of water from all the sprinkler heads in the affected area. Deluge systems are often found in power plants, chemical storage areas, and aircraft hangars.

5. Pre-Action Deluge Sprinkler Systems

Pre-action deluge systems combine pre-action and deluge systems. These systems require a fire detection signal and sprinkler head activation to release water. Once both triggers are met, the deluge valve opens, and water simultaneously discharges through the sprinkler heads. Pre-action deluge systems are used where quick fire suppression is crucial. Still, there is also a concern for accidental water discharge, such as in computer server rooms, flammable liquid storage areas, and industrial facilities.

Summary

Fire sprinkler systems are available in various types to suit different environments and safety requirements. Whether it's a wet pipe system for a commercial building or a deluge system for a high-risk area, the primary goal remains to detect and suppress fires effectively, minimising damage and saving lives. Understanding the different types of fire sprinkler systems helps ensure the right choice is made to protect against fire hazards in various settings.
