How Sprinkler Systems Can Save Your Building

Sprinkler systems don’t just protect your building from potential fires, but from alien invasions too!

I think we all agree, it’s best to be prepared for anything. We’ve seen quite a few once-in-a-lifetime events in the last few months, proving that anything can really happen. We’ve seen footage of UFOs, a Firenado, simultaneous hurricanes, and, oh yes, a global pandemic this year. So how outrageous could an alien invasion be?

As we’ve seen in Aliens 3, the best way to defeat aliens is by using your building’s sprinkler system. Aside from protecting you from an alien invasion, why do commercial buildings require sprinkler systems?

The reason you need a fire sprinkler system

Fire sprinkler systems assist all your fire safety protocols in fighting potential fires and protecting your building’s assets, people, and contents. These systems are an active measure to protect against fires and prevent lives and property damage. They help to limit the fire’s spread and give firefighters ample time to save your building.

Fire sprinklers detect heat from a fire source and trigger the sprinkler head to release water in specific locations. Their purpose is to extinguish the fire or slow it down before the firefighters arrive.

How do I know if a fire sprinkler system is required for my building?

Most commercial buildings require a sprinkler system to be installed, especially in new construction, remodels, and renovations. There are a few sprinkler systems requirements in commercial buildings, the International Building code states the following: 

  1. Sprinkler systems allow builders to increase the footprint of the building. 

Adding sprinkler systems throughout your building allows for a larger building footprint and a higher building height. At VFS, our teams help to plan and budget for new construction sites and assist your team from the planning stages all the way through to completion. Our in-house Design/Build departments produce the highest quality and most accurate results to ensure the safety of your building.

  1. Different occupancies and uses require specific systems.

Certain commercial buildings use group or occupancy-use to determine how the sprinkler systems will be implemented throughout the building. All residential buildings require occupancy load determinants, while other commercial buildings typically use fire areas to determine sprinkler systems management.

  1. Special hazards require sprinkler systems. 

Special hazards environments require the most reliable and advanced fire suppression systems on the market. At VFS we provide not only the systems but the specialized knowledge and certified and trained technicians who install, service, and inspect special hazards fire protection systems including, deluge, foam-based, water mist, dry chemical, and clean agent systems, including FM-200 and carbon dioxide. Special hazard safety begins with the professional integration of the specific fire protection systems required within the environment.

What type of commercial fire sprinkler systems do you need?

Wet Pipe Commercial Sprinkler Systems

Wet pipe commercial sprinkler systems are made up of piping that fills with water when under pressure. These pipes remain filled with water until a fire triggers the sprinkler head to turn on. These are the most frequently used sprinkler systems, as they are extremely simple to use and reliable when you need them most. These systems are also cost-effective in both installation and maintenance. One of the major issues with these sprinkler systems is leaks can occur when temperatures go below 40 degrees Fahrenheit.

Pre-Action Commercial Sprinkler Systems

In certain commercial buildings, some instances may cause sprinkler systems to discharge accidentally. Pre-action sprinkler systems are designed with a valve to hold water back until certain events have taken place that will then trigger water to flow within the pipes and extinguish the fire. There are two types of pre-action systems, single interlock, and double interlock. These systems require certain events to happen in order to trigger water to flow. Let’s talk about them! 


Single Interlock 

Single interlock pre-action systems operate in a similar manner as the dry pipe system. This type of system requires a singular event to occur before water is released into the system; fire detection from a heat or smoke detector that will trigger the pre-action valve to open.

Each sprinkler head individually opens, to ensure the sprinkler head doesn’t turn on preemptively. These systems are uniquely effective for spaces that contain sensitive equipment or costly materials. However, these systems are complex in design, which therefore makes them higher in installation price and in maintenance costs.

Double Interlock 

As you could probably guess the double interlock pre-action system requires two events to occur before releasing water in the system; fire detection from a heat or smoke detector and automatic sprinkler operation. One of the above actions occurs the pre-action valve operates allowing water into the system piping. These actions introduce an extra layer of security from accidental discharge where unintended activation can be damaging to sensitive environments. 

Foam Water Commercial Sprinkler System

Typically sprinkler systems utilize water to extinguish fires. However, for some fires, water will actually make it worse. Foam water fire sprinkler systems mix water with foam concentrate mix that works to put out the fire. The fire started by gas or alcohol needs a foam solvent to extinguish it as quickly and as safely as possible. The foam is used to stifle the flames and eliminate the opportunity for a re-flash. 

Dry Pipe Commercial Sprinkler Systems

These sprinkler systems were designed to mitigate the leaking issue that comes with wet pipe sprinkler systems. Rather than pressurized water remaining in the entire sprinkler system, these systems are only filled with air or nitrogen indirect, non-heated piping. These systems are designed for buildings that reside in freezing temperatures. Because the water doesn’t reside in the piping system from the start, these sprinkler systems have a delay of up to 60 seconds until the water is discharged. 

Deluge Sprinkler Systems

Deluge fire sprinklers are used in high hazard environments such as power plants, aircraft hangars, and chemical storage facilities where significant amounts of water are needed to cool and control the development of a fire. They are connected to a water supply through a deluge valve while the sprinkler heads remain open which releases water to all open sprinkler heads simultaneously. These systems are incredibly effective in high-hazard environments because they release water or another suppressing agent to all open sprinkler heads simultaneously.

At VFS Fire & Security Services we don’t stop at the basics, we apply our full book of expertise to the systems that need them and follow the specific requirements depending on the particular authority having jurisdiction. Every environment is unique and has its own set of specific requirements and the experts at VFS will help get your business up to code every step of the way.

You need to be prepared for whatever comes your way — including alien invasions! At VFS, we offer preventative and inspection maintenance to ensure your systems are running effectively and efficiently. 

Your business needs to be kept safe, we understand what it takes to make that happen.
