Fire prevention is a top priority for any industrial or commercial organization. To prevent fires from breaking out, organizations have to rely on reliable fire suppression systems that can protect their property, employees, and customers from harm. Two popular fire suppression systems in use today are preaction and deluge sprinkler systems. While both systems are designed to extinguish fires, there are some key differences between the two.
At first glance, the preaction and deluge sprinkler systems look similar, but they differ in their operating mechanism. A deluge sprinkler system is designed to release a large volume of water over a wide area in the event of a fire. This system is suitable for high-risk areas that need immediate and comprehensive fire suppression, such as chemical and industrial processing plants. In contrast, a preaction sprinkler system operates differently, as it relies on two stages of activation before water is released. The preaction system is commonly used in areas where water damage from false alarms is a significant concern.
In this article, we will explore the differences between preaction and deluge sprinkler systems, their applications, and their advantages and disadvantages. It is important to understand the distinctions between the two systems to ensure that your organization is equipped with the right fire suppression system to meet its specific needs. Keeping your employees and property safe and protected from fires is essential, and selecting the right fire suppression system is a crucial part of this objective.
Types of Fire Sprinkler Systems
Fire sprinkler systems are designed to protect people and property from the damaging effects of fires. There are several different types of fire sprinkler systems available, each with its own unique features and benefits.
- Wet Pipe Sprinkler Systems
- Dry Pipe Sprinkler Systems
- Preaction Sprinkler Systems
- Deluge Sprinkler Systems
- Foam Sprinkler Systems
- Water Mist Sprinkler Systems
- Special Hazard Sprinkler Systems
Of these systems, preaction and deluge sprinkler systems are two of the most commonly used in industrial and commercial settings. While both types of systems are designed to quickly suppress fires, there are significant differences between them.
Preaction Sprinkler Systems
Preaction sprinkler systems are typically used in environments where water damage must be avoided at all costs. These systems use a two-step process to activate the sprinkler heads. The first step involves opening a preaction valve that allows pressurized air or nitrogen to fill the pipes. The second step involves the activation of the sprinkler heads, which release water only when they are exposed to heat.
Preaction systems are typically used in environments where extremely sensitive equipment, such as computer servers or art collections, need to be protected. Because water is not flowing through the pipes until the sprinkler heads are activated, the risk of accidental discharge or leaks is minimized.
|Minimizes water damage||More complex and expensive to install|
|Less risk of accidental discharge or leaks||Requires regular maintenance to ensure proper operation|
|Can be used in environments with sensitive equipment or materials||Requires a separate detection system to activate the sprinkler heads|
Preaction systems are typically more complex and expensive to install than other types of sprinkler systems. They also require regular maintenance to ensure proper operation. However, for environments where water damage must be avoided at all costs, preaction sprinkler systems are often the best choice.
Overview of Preaction Sprinkler Systems
Preaction sprinkler systems are a type of fire suppression system designed to protect high-value assets from potential water damage. These systems, unlike deluge systems, are designed to trigger only when double criteria are met. They are referred to as pre-action because they require a preliminary activation signal to be sent before releasing water to the protected area.
Preaction Sprinkler System Components
- Air compressors
- Detection devices
- Pre-action valve
- Piping network
- Hangers and seismic bracing
The preaction sprinkler system has a wide range of components. The air compressor is used to keep the piping dry and pressurized. Detection devices are used to signal the system when a fire has started. Other essential components include pre-action valves, piping networks, hangers and seismic bracing, and sprinklers.
Preaction Sprinkler System Types
There are several types of preaction sprinkler systems designed to complement various building and industrial applications. These systems include:
- Single interlock systems: This system requires a signal from the detection devices and sprinkler activation before water is released.
- Double interlock: A signal from the detection devices and sprinkler activation is needed before allowing water to flow through the system.
- Non-interlock: These are the most basic preaction sprinkler systems designed to open automatically when a fire is detected.
Preaction Sprinkler System Advantages
The preaction sprinkler system is a perfect solution for high-value assets that run the risk of significant water damage or overexposure. The system provides unique benefits, including:
|Reduced water damage||The preaction system only triggers in the protected area, reducing collateral damage.|
|Saves cost and time||The air compressor keeps the water from flowing through the sprinklers when the system is not yet activated, reducing maintenance costs.|

Overall, preaction sprinkler systems provide a high level of protection with reduced water damage and cost savings. Their customizable nature ensures that they can be incorporated into different types of buildings and industrial applications.
Overview of Deluge Sprinkler Systems
If you are a building owner or manager, you must be familiar with sprinkler systems that are meant to put out fires and save lives. Among the various sprinkler systems available, deluge sprinkler systems are one of the most effective types. Let’s take a closer look at what they are and how they work.
- What is a deluge sprinkler system? A deluge sprinkler system is a type of fire protection system designed to quickly flood an entire area with water in case of a fire. Unlike other sprinkler systems, all the sprinkler heads in a deluge system are open all the time. The system is activated by an alarm or heat detection system, which sends a signal to open the deluge valve. Once the valve is open, water flows into all the sprinkler heads, which then spray water all over the protected area.
- How does a deluge sprinkler system work? The working principle of a deluge sprinkler system is simple but effective. When a fire is detected, the deluge valve opens, allowing water to flow through all the open sprinkler heads. The sprinkler heads are specially designed to distribute water over a large area quickly and effectively. The system is designed to suppress the fire completely by providing a large volume of water in a short period.
- Where are deluge sprinkler systems commonly used? Deluge sprinkler systems are commonly used in areas where there is a high risk of fire, such as power plants, chemical plants, and aircraft hangars. These areas generally store flammable materials that pose a severe risk in a fire. The deluge system is designed to contain and suppress the fire before it can spread and cause more damage to the facility and equipment.
Deluge sprinkler systems are an essential part of fire protection systems, especially in high-risk areas. The systems are designed to react quickly and provide large volumes of water to suppress fires effectively. If you own or manage a facility where there is a high risk of fire, a deluge sprinkler system might be the best investment you can make to protect your people and property.
Here’s a summary of the key features of deluge sprinkler systems:
|Open sprinkler heads||All the sprinkler heads in a deluge system are open all the time.|
|Activated by detection system||The system is activated by an alarm or heat detection system|
|Floods entire area with water||The system is designed to flood the entire area with water quickly and effectively.|
|Quickly suppresses fires||The system provides a large volume of water in a short time to suppress the fire effectively.|
As you can see, a deluge sprinkler system is an essential fire protection system that can help prevent severe damage to a facility and its people. If you are considering installing a fire protection system in your building, a deluge sprinkler system can be an excellent investment in the safety of your property and people.
How Preaction Sprinkler Systems Work
Preaction sprinkler systems are a specialized type of fire suppression system that require two separate triggers before water is released. These systems are typically used in areas with sensitive equipment or valuable assets, as they provide an extra layer of protection against accidental or unintended water damage.
- First Trigger: The preaction valve must be activated. This valve is typically controlled by a fire alarm system, so when a fire is detected, the valve opens allowing water to flow into the piping network.
- Second Trigger: The individual sprinkler heads must be activated. Unlike a deluge system, where all the sprinkler heads activate simultaneously, preaction systems only activate the sprinklers closest to the fire. This prevents water damage from occurring in areas not affected by the fire.
- Combined Activation: Once both triggers are activated, water will flow from the sprinkler heads in the affected area. This targeted approach helps to minimize water damage and increase the chances of saving valuable assets.
Preaction systems are also classified as either single-interlock or double-interlock. Single-interlock systems require additional heat or smoke detection to trigger the valve, while double-interlock systems require both fire detection and sprinkler activation before water is released.
Overall, preaction sprinkler systems offer a unique form of fire suppression that provides targeted protection for sensitive areas. By requiring two separate triggers before water is released, these systems can help minimize damage and protect valuable assets.
|Minimizes water damage||Higher installation and maintenance costs|
|Protects sensitive equipment and assets||Requires additional fire alarm and detection systems|
|Targeted approach to fire suppression||May require professional monitoring and servicing|
When deciding on whether or not to install a preaction sprinkler system, it’s important to weigh the pros and cons and consider the specific needs of the area being protected.
How Deluge Sprinkler Systems Work
If you want a sprinkler system that can handle an extremely fast fire, a deluge sprinkler system may be your best option. These systems work by releasing large amounts of water through all of the sprinkler heads simultaneously. Rather than waiting for heat to activate an individual sprinkler head, a deluge system is designed to activate all of the heads at once.
- This is especially useful in areas where fires can spread rapidly, such as chemical storage facilities or airplane hangars.
- Deluge systems are also commonly used in outdoor areas that are prone to large fires, like oil refineries.
- Because of their design, deluge systems are typically activated manually or by a signal from a fire alarm system. This means that if an area is at risk for fire, the sprinklers can be activated quickly and efficiently, potentially saving lives and property.
Here is a breakdown of how deluge sprinkler systems work:
|1||The deluge valve is opened, allowing water to flow into the piping system.|
|2||As the water flows through the pipes, it passes through a detector that triggers the release of water at all of the sprinkler heads.|
|3||Water is released at high pressure through all of the open sprinkler heads, quickly dousing any flames in the affected area.|
|4||The deluge valve remains open until it is manually closed or the fire is completely extinguished.|
Overall, deluge sprinkler systems are a powerful option for industrial and outdoor fire protection. While they may not be the best choice for all types of properties, they are an effective tool for preventing and minimizing damage from large, fast-moving fires.
Advantages of Preaction Sprinkler Systems over Deluge Sprinkler Systems
Preaction sprinkler systems are gaining popularity over deluge sprinkler systems due to their many advantages. Preaction systems use both heat and detection systems, making them more precise and reliable. Here are some of the main advantages of preaction sprinkler systems:
- Less water damage: Preaction sprinkler systems use targeted water release, meaning only the area in danger of fire is getting wet. This keeps water damage to a minimum, unlike deluge systems, which release water everywhere.
- No accidental discharges: Preaction systems require two triggers (smoke and heat) before they activate, greatly reducing the chance of an accidental discharge. Deluge systems, on the other hand, have a higher chance of misfiring due to their single trigger volume release.
- Less business interruption: Preaction systems can be customized to protect sensitive equipment without shutting down the entire system. Deluge systems, due to their all-or-nothing nature, could result in a longer business interruption.
Overall, preaction sprinkler systems offer a more precise, reliable, and customizable solution to fire protection. While deluge systems continue to have their uses, it’s no surprise that preaction systems are quickly becoming the preferred choice for many businesses looking to protect their property.
For business owners and property managers seeking a reliable fire protection solution that minimizes disruption and maximizes protection, preaction sprinkler systems are an effective and efficient option.
When in doubt, consulting a professional fire safety expert to discuss specific needs and risk factors should be your first step in any fire safety plan.
Advantages of Deluge Sprinkler Systems over Preaction Sprinkler Systems
While both preaction and deluge sprinkler systems are commonly used in various industries, deluge sprinkler systems have a few advantages over preaction systems:
- Quick response time: Deluge systems offer a quicker response time compared to preaction systems. This is because the deluge system is activated once the sprinkler head is triggered, whereas preaction systems require additional time for the detection and activation process.
- Higher volume of water: Deluge systems use a higher volume of water than preaction systems. This is because all the sprinkler heads in a deluge system are open and release water simultaneously, while in preaction systems, only sprinkler heads in the activated area release water.
- Effective for high hazard areas: Deluge systems are an excellent option for high hazard areas, such as areas with flammable liquids or gases, while preaction systems are more suited for areas with low risks of fire.
Here’s a table for a side-by-side comparison:
|Deluge System||Preaction System|
|Area of application||High hazard areas||Low hazard areas|
Overall, when it comes to selecting between a preaction and deluge sprinkler system, it’s crucial to assess your facility’s risks and challenges. Deluge systems are great for high hazard areas that require water quickly and in large quantities. On the other hand, preaction systems are best suited for areas where accidental water discharges can cause significant damage.
