Deluge Fire Sprinkler Systems

Read More or Call Fire Pros at (800) 968-2871 for Service!

When it comes to protecting your building from fire, no single system is more effective than automatic fire sprinklers. These systems actively douse flames even when no one is in the building, providing 24/7 fire protection.

In ordinary settings, it’s important for only one sprinkler head to engage at a time. This effectively douses the fire below without causing excessive water damage. However, if you operate a high-hazard building where it’s imperative to stop the spread of fire instantly, deluge fire sprinklers could be the right solution.

Contact Fire Pros or call (800) 968-2871 for information about installing a fire sprinkler system.

What Is a Deluge Fire Sprinkler System?

Deluge systems connect to the water supply via a deluge valve. When the smoke or heat detection system activates in the presence of a fire, every linked sprinkler head engages at the same time. It’s also possible to manually activate deluge fire sprinklers if an attentive onlooker notices the flicker of flames before the smoke or heat detectors sense them.

Once the valves are open, they must be closed manually. Often, this means using pliers at the mainframe, which may be located in the basement or utility room.

In order for the sprinkler heads in a deluge system to engage all at once, they remain open at all times. This way, when the deluge valve activates in response to a fire, water flows from all discharge devices simultaneously. This differs from conventional sprinkler systems, in which each head features a glass bulb that breaks when exposed to high temperatures and allows water to flow.

In addition to applying water, some deluge systems incorporate foam concentrate. When mixed with the discharging water, a foam solution is created that smothers the fire and further assists with cooling the room and extinguishing the flames.

Where Are Deluge Fire Sprinklers Used?

Deluge fire sprinklers are appropriate for extra hazard occupancies. In these settings, high-velocity suppression is needed to prevent flames from spreading. Such applications include:

  • Power plants
  • Aircraft hangars
  • Chemical processing facilities
  • Hazard materials storage
  • Oil extraction processes
  • Transformers
  • Tanks or vessels
  • Distillation process centers
  • Any other building containing low–flashpoint flammable liquids or a large amount of combustible liquids

Testing Requirements for Deluge Fire Sprinklers

Once your deluge system is installed, you can’t simply forget about it. Compliance with NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems requires the following:

  • Inspect gauges weekly to ensure adequate air and water pressures.
  • Conduct a trip test on the deluge valve annually.
  • Inspect the interior condition of the deluge valve once a year when the trip test is performed. Clean and repair/replace any parts as needed at this time.
