Wet Sprinkler Systems

Wet pipe systems are by far the most common and most cost-effective of the four fire sprinkler technologies. Constantly charged with water, wet sprinklers are designed to discharge at a specified temperature, limiting and controlling the spread of fire.

Keystone designs, installs, inspects, and services wet sprinkler systems, as well as fire pumps and backflow preventers, which are critical to effective operation and compliance with codes.

Benefits of Dry Sprinkler Systems
Benefits
• Protect areas that are not climate controlled
• Air pressure is supervised so you are notified of any pipe leaks prior to the flow of water and damage to property
Dry System Limitations

Limitations

• More complex than wet pipe systems
• Requires a continuous gas supply
• The larger the system, the longer it takes to get water to the activated sprinkler head
• System size limitations due to the delayed dispersal of water from the dry-pipe valve to the open sprinklers
• Sizing limitations could necessitate multiple systems
Dry System Applications
Applications

• Parking garages
• Exterior canopies
• Attics

• Warehouses
• Loading docks
• Refrigerated cooler

DRY Sprinkler Systems

Dry pipe fire sprinkler systems are the system of choice when the piping will be exposed to temperatures below 40 degrees F. Dry sprinkler system piping does not contain any water and is charged with pressurized gas (compressed air or nitrogen). When a fire occurs and generates enough heat to release the sprinklers, the gas in the pipes escapes, resulting in a drop in system gas pressure, which allows the dry valve to open and water to flow to the activated sprinklers.

PRE-ACTION SPRINKLER SYSTEMS

Pre-action sprinkler systems are specialized for use in locations where accidental activation could damage high value physical assets. Similar to a dry-pipe system, a pre-action sprinkler system uses piping charged with air or nitrogen under pressure. The pre-action system holds back the water with an electrically operated valve, known as a pre-action valve. Water will not flow into the system until the supplemental fire detection system operates, signaling the pre-action valve to open.

Benefits of Pre-Action Systems
Benefits
• Ideal for water sensitive environments
• This system can allow assessment of the incipient fire prior to water release, potentially saving valuable assets from water damage
• Designed to prevent unwanted activations
Pre-Action System Limitations
Limitations
• Requires a supplemental fire alarm detection system
• Higher cost to inspect and maintain
• More system complexity
Pre-Action System Applications
Applications

• Archive Vaults
• Museums
• Tape Libraries

• Data Centers
• Freezers
• Electrical Rooms

Benefits of Deluge Systems
Benefits
• Massive amounts of water in a short amount of time
• Contains fire and cools surrounding area to prevent fire spread
• Can be combined with foam for flammable liquid fires
• The only sprinkler system that can be manually activated
Limitations of Deluge Sprinkler Systems
Limitations
• System sizing limitations
• Requires supplemental fire alarm detection system
• Water is released through every head – whether you need it or not
• Typically requires ancillary fire pump to provide necessary water supply
Where Deluge Sprinkler Systems Are Used
Applications

• Aircraft Hangars
• Fuel Loading Racks
• Power Plants
• Chemical & Hydro-Carbon Storage
• Processing Facilities

DELUGE SPRINKLER SYSTEMS

Like a pre-action sprinkler system, a deluge system holds back water via an electrically operated deluge valve. However, unlike pre-action systems, the sprinkler heads are always open, and the piping is not pressurized with air.

When the automatic detection system activates, the valve is opened and water releases through all the heads simultaneously, releasing copious amounts of water.

Benefits of Deluge Systems

• Massive amounts of water in a short amount of time
• Contains fire and cools surrounding area to prevent fire spread
• Can be combined with foam for flammable liquid fires
• The only sprinkler system that can be manually activated

FOAM SPRINKLER SYSTEMS

Flammable liquid fires cannot be contained with water alone and require foam for extinguishment.  Foam, mixed with water, blankets the liquid that is on fire, eliminating the oxygen supply and extinguishing it.

AFFF foam has a significant water content, which forms an aqueous layer over the flames that not only puts out the fire but also helps cool the burning liquid and prevent re-ignition.

 FFFP foam is essentially a combination of AFFF foam and fluoro protein foam that combines the extreme burn resistance of a fluoro protein foam with the cooling and fast-acting aqueous layer of AFFF foam.

Benefits of Foam Systems
Benefits
• Highly effective on flammable liquid fires
• Quickly fill up large volumes with high expansion foam
• More efficacious than water alone
• Multiple delivery systems: manual hose reel, wet sprinkler, pre-action, or deluge
Foam System Limitations
Limitations
• Foam concentrate has a shelf life and must be replaced periodically
• Must be tested annually
• Comparatively higher cost to inspect and maintain
• Can be detrimental to ground water supplies
Foam System Applications
Applications

• Manufacturing
• Refineries
• Processing Facilities
• Warehouses
• Airport Hangars
• Marinas

AUXILIARY SPRINKLER SYSTEM COMPONENTS

Here are some of the most common components associated with sprinkler systems.

FIRE PUMPS

wet sprinkler pump

An automatic fire pump is an adjunct to a sprinkler system that provides additional water pressure and volume when municipal supply is inadequate for the hazard. They are typically used in high rise buildings, large warehouses, and systems without a positive pressure water supply (tanks, lakes, ponds, etc).

STANDPIPES

Standpipes are a vertical piping network, typically found in stairwells, designed for use by fire departments to extend their ability to fight fires within multi-story buildings. Standpipes can be either wet or dry, subject to the same environmental limitations as wet and dry sprinkler systems.

BACKFLOWS

Backflow prevention assemblies (BFPs) inhibit the reverse flow of brackish sprinkler water that could otherwise contaminate the drinking water supply.  BFPs are required on potable water lines serving fire sprinkler systems, fire service standpipes, and fire hydrants.

STOP FIRES FAST

Fire sprinkler systems can be an effective and affordable way to protect your people and property but arriving at the ideal system for your business takes considerable expertise. Let us create the right solution for you.
