Quick Guide to the Types of Residential Fire Sprinkler Systems

The Importance of Fire Safety in Your Home

Your home is your sanctuary, a place of comfort and security for you and your loved ones. However, fire poses a significant threat to this sense of safety. Every year in the US, home fires cause thousands of deaths and billions in property damage.

While smoke detectors are essential fire safety tools, they only serve as an early warning system. Residential fire sprinkler systems take fire suppression a step further. These home fire sprinkler systems actively extinguish or controll the blaze in its early stages.

Why are residential fire sprinkler systems important?

The benefits of residential fire sprinkler systems are obvious:

Enhanced fire protection

The CDC says that "fire sprinklers are the most effective way to control a fire in its early stages". The NFPA further emphasizes that residential fire sprinklers can reduce the risk of death in a fire by 80%. They can also reduce property damage by up to 70%.

Potential reduction in property damage

By controlling the fire early, sprinkler systems can significantly minimize the damage caused. The HSFC states that "in fires where sprinklers operate, they extinguish or control the fire 99% of the time".

Lower insurance premiums

The IBHS reports that "homes with fire sprinklers have, on average, 60% lower fire insurance premiums". This reduction reflects the lower risk of fire damage associated with sprinkler-equipped homes.

By installing a fire sprinkler system for residential buildings, you invest in the safety of your family. You are also protecting your property.

Understanding the Different Types of Systems:

All residential fire sprinkler systems share the common goal of extinguishing or controlling fires. Though, they differ in their design and operation. Here's a breakdown of the three main types of residential fire sprinkler systems:

Fire Sprinkler

Wet Fire Sprinkler Systems: Reliable and Always Ready

  • Description: Wet fire sprinkler systems are the most common type for residential applications. Wet Sprinkler Systems constantly have water under pressure in them, allowing an immediate response to a fire.
  • Operation: When a fire is detected, a heat-sensitive bulb in the sprinkler head breaks. This releases water to extinguish the flames.


  • Reliable and quick response: Wet systems offer a fast and dependable activation in the event of a fire.
  • Cost-effective: They are generally the most affordable option compared to other types of systems.


  • Prone to freezing: Wet systems are not suitable for unheated spaces or freezing temperatures.

Dry Fire Sprinkler Systems: Ideal for Freezing Climates

  • Description: Dry fire sprinkler systems excel in areas susceptible to freezing temperatures. They are filled with compressed air instead of water until a fire is detected.
  • Operation: When a fire is triggered, the heat activates a two-stage process. First, the compressed air is released from the pipes. Then, a separate water supply line fills the system with water, and the sprinkler heads extinguish the fire.


  • Suitable for cold climates: Dry systems eliminate the risk of frozen pipes.


  • More complex and expensive: The two-stage activation process makes dry systems more expensive. They are also harder to maintain because of their extra residential sprinkler system components.
  • Slightly slower response: The two-stage activation might cause a slight delay in water discharge compared to wet systems.

Preaction Fire Sprinkler Systems: Offering an Extra Layer of Protection

  • Description: Preaction fire sprinkler systems combine features of both wet and dry systems. They function best where water discharge could cause significant damage, such as computer rooms or art galleries.
  • Operation: Similar to dry systems, preaction systems are filled with air in their inactive state. When a fire is detected, a two-stage activation occurs.
  • First, a pressurized air signal is released, followed by the release of water into the pipes. However, the sprinkler heads themselves have a pre-action valve that requires an additional signal. This typically comes from a heat detector located closer to the fire, to rupture and discharge water.


  • Minimizes accidental water discharge: The pre-action valve prevents water release from accidental activation. This could include an instance such as a broken sprinkler head.
  • Suitable for sensitive areas: This feature makes preaction systems ideal for protecting areas where water damage could be costly.


  • Most complex and expensive: Preaction systems are the most complex and expensive option among the three types. This is because of their dual-stage activation and additional components,
  • Slowest response: The additional pre-action step introduces a slight delay in water discharge compared to other systems.

Choosing the right type of residential fire sprinkler system depends on various factors. These include your climate, budget, and the specific needs of your home. Consulting with a qualified fire protection professional can help you determine the best system for your situation.

Exploring Additional System Options

Having a deeper understanding of residential fire sprinkler systems can empower you to make informed decisions:

What are the main components of a residential fire sprinkler system?

A typical residential fire sprinkler system consists of the following components, as outlined by Bob Vila:

  • Water supply: This can come from the municipal water main or a private well. Having a large water supply will ensure adequate water pressure for the system to function effectively.
  • Main control valve: This valve regulates the flow of water to the entire system. It allows for activation and shutoff during maintenance or emergencies.
  • Piping network: This network of pipes distributes water throughout the house, reaching all areas protected by sprinkler heads.
  • Sprinkler heads: These are the discharge points where water is released to extinguish the fire. We will explore different types of sprinkler heads in more detail in the next section.
  • Fire alarm system: This system is often integrates a fire alarm system with sprinklers. It sounds an alarm when a fire is detected, alerting occupants and potentially calling for help from emergency services.

Residential Fire Sprinkler Heads: Choosing the Right Type

The selection of sprinkler heads for your system hinges on factors like the room's purpose and potential fire hazards. Here's an overview of the two main types of residential fire sprinkler heads:

Spray heads

These are the most common type, discharging a cone-shaped water pattern to extinguish or control the fire. They are suitable for most living areas within a home.

Deluge heads

These are typically used in specific areas with high fire risk, such as basements or garages. They discharge a large volume of water in a short period, aiming to suppress the fire rapidly.

Consulting with a fire protection professional can help you choose the right sprinkler heads for your specific needs. Doing this will ensure optimal fire protection throughout your home.

Concealed vs. Exposed Sprinklers: Balancing Aesthetics and Functionality

Residential fire sprinkler systems can be installed in two main configurations:

Concealed Fire Sprinkler Systems

These are embedded within the ceiling or walls, offering a visually discreet appearance. They are particularly suitable for areas where aesthetics are a major concern.

Exposed sprinklers

These are visible on the ceiling or walls. They might be less aesthetically pleasing compared to concealed options. However, they are generally easier and less expensive to install and maintain. An example of exposed sprinklers are pendant fire sprinklers.

The choice between concealed and exposed sprinklers depends on your individual priorities, weighing the importance of aesthetics against ease of installation and maintenance considerations.

Installation of Fire Sprinkler Heads

Are there any drawbacks to residential fire sprinkler systems?

While the benefits of residential fire sprinkler systems are undeniable, it's important to acknowledge some potential drawbacks:
