Fire Sprinkler Systems

 

Wet Sprinkler Systems

The most common type of sprinkler system where water is constantly maintained within the system piping.

Wet pipe system is one in which water is constantly maintained within the sprinkler piping. When a sprinkler activates this water is immediately discharged onto the fire. Wet Pipe Sprinkler Systems are designed for use in applications where the temperature is maintained above freezing. In such systems, the entire piping network is fully pressurized so that water is discharged from a sprinkler head immediately after actuation. Alarm check valves or water flow detectors are used to actuate local and remote alarms. Champion has an entire team of skilled professionals focused on sprinkler systems design, installation, and maintenance

Applications include:

  • Heated Warehouses
  • Factories
  • Hospitals
  • Stores
  • Shopping Centers
  • Residential settings such as Apartment or Condominium Complexes, and Single Family Residences

Dry Sprinkler Systems

A sprinkler system for use where freezing temperatures may exist.

Dry Sprinklers have been specifically designed for areas in which the sprinkler may be subjected to freezing conditions. A dry pipe sprinkler system is a system with automatic sprinkler heads attached to a piping system containing air or nitrogen under pressure. The release of this pressure (caused by the opening of a sprinkler head) permits the water pressure to open a valve known as a dry pipe valve and the water then flows into the piping system and out of the open sprinkler head. At the same time local and/or central station alarms can activate, along with other integrated system components such as fire alarm notification devices.

Dry Sprinkler Systems

Accessory items, such as dry pipe valve accelerators that increase the speed of system operation, and switches used to activate electric alarms, may be used to enhance the system. Valves for the system, must be installed in areas not subject to freezing, as this portion of the system does contain water. The system may be equipped with automatic or manual air supply controls and air supervisory devices with appropriate trouble alarms.

Applications include:

  • Unheated Warehouse
  • Parking Garages
  • Store Windows
  • Attic Spaces
  • Loading Docks
  • Covered Exterior Platforms
  • Other Areas Exposed To Freezing Temperatures

Pre-Action Systems

A closed head sprinkler system where water does not enter the system until a detection event triggers the pre-action valve, at which point the head still needs to trip in order to activate the entire system.

Pre Action Fire Sprinkler System

A Champion pre-action sprinkler system is similar to a deluge sprinkler system except the sprinkler

heads are closed. This type system is typically used in areas containing high value equipment or contents and spaces which are highly sensitive to the effects of accidental sprinkler water discharge.

The pre-action valve holds back water from entering the system until it is tripped by a separate electronic detection system. Activation of a heat or smoke detector in that separate system will open the pre-action valve, allowing water to enter the system piping. Because the sprinkler heads are closed, water will not flow from the sprinklers until heat activates the operating element in individual sprinkler heads. Basically, the automatic opening of the pre-action valve effectively converts the system to a wet pipe sprinkler system.

In a pre-action system the piping is pressurized with air or nitrogen, monitoring of this air pressure provides a means of supervising the system piping. Loss of the supervisory air pressure in the system piping results in a trouble signal at the alarm panel. A pre-alarm of a possible fire allows time for alternate fire extinguishment prior to a sprinkler discharge. In the event the fire cannot otherwise be extinguished, the preaction sprinkler system will then perform as the primary fire protection system. They are designed for applications such as refrigerated areas that require maximum protection against inadvertent operation of the sprinkler system.

Applications include:

  • Flammable Liquid Handling
  • Storage Areas for Valuable Artifacts
  • Aircraft Hangars
  • High-Hazard Installations Using Water as Extinguishing Agent
  • Computer Rooms
  • Libraries
  • Archives
  • Refrigerated Spaces

Deluge Sprinkler Systems

Similar to a Pre-Action system with open heads, to deliver a large volume of water immediately upon activation.

Deluge Systems are normally used in special hazard installations where water must be applied to an Deluge Sprinkler Systementire area for protection. The arrangement of deluge system piping is similar to a wet or dry pipe system with two major differences: Standard sprinkler heads are used, but they are all open. The activating elements have been removed so that when the control valve is opened water will flow from all of the sprinklers simultaneously and deluge the area with water.

The deluge valve is normally closed. The valve is opened by the activation of a separate fire detection system. Deluge systems are used where large quantities of water are needed quickly to control a fast-developing fire. Deluge valves can be electrically, pneumatically or hydraulically operated, and often opened by a fire detection system installed in the same area.

Applications include:

  • Flammable Liquid Handling
  • Storage Areas for Valuable Artifacts
  • Aircraft Hangars
  • High-Hazard Installations Using Water as Extinguishing Agent
  • Computer Rooms
  • Libraries
  • Archives
  • Refrigerated Areas

Foam Sprinkler Systems

A sprinkler system that uses special components and foam agents to suppress fires. Foam-based Sprinkler Systems most commonly use the balanced pressure proportioning method for flammable liquid fire protection applications. They are designed to accurately control the flow of a foam liquid concentrate into a water stream over a wide range of flow rates and pressures.

Two basic types, bladder tanks and pump systems, require the foam concentrate pressure to be balanced with the water pressure at the proportioner which meters the proper amount of foam concentrate into the water stream. The resulting foam solution is piped to discharge devices protecting the hazard area.

Foam liquid concentrates are suitable for use on fires involving ordinary hydrocarbon petroleum products, and some foam liquid concentrates may also be suitable for use on fires involving polar solvent fuels.

A Champion fire protection system designer first identifies the fuel load and selects the foam liquid concentrate according to its ability to be used for a given fuel load. Upon selecting the foam liquid concentrate, the designer then selects equipment, including discharge devices, based on listing/approval compatibility of the equipment with the concentrate.

Applications include:

  • Class B Hydrocarbon Fuel Fires Such as Crude Oils, Gasoline, Diesel Fuels & Aviation Fuels
  • Class B Polar Solvent Fuel fires such as Methyl Alcohol, Acetone & Ethyl Alcohol
  • Loading Racks
  • Aircraft Hangars
  • Refineries
  • Marine Vessels
  • Warehouses

Fire Pump Sprinkler Systems

Fire Pump Sprinkler System

Fire pumps boost the pressure to a facility when the sprinkler system is activated–and are often required in tall structures.

Champion is experienced with a variety of types and styles of fire pumps and can service, inspect, and design a sprinkler system to work with many types of fire pumps.

A fire pump is a part of a fire sprinkler system’s water supply. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes.

Fire pumps may be powered either by an electric motor or a diesel engine, or, very occasionally a steam turbine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize, when connected via a listed transfer switch, the installation of an emergency generator.

The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature, and opens, releasing water. Alternately, other fire hoses reels or other firefighting connections are opened, causing a pressure drop in the fire fighting main.

Fire pumps are needed when the local municipal water system cannot provide sufficient pressure to meet the hydraulic design requirements of the fire sprinkler system. This usually occurs if the building is very tall, such as in high-rise buildings, or in systems that require a relatively high terminal pressure at the fire sprinkler in order to provide a large volume of water, such as in storage warehouses. Fire pumps are also needed if fire protection water supply is provided from a ground level water storage tank.
