Automatic Fire Sprinklers and Suppression Systems

The Automatic Sprinkler Systems within a building is a key mechanical component.

The sprinkler systems are intended to actively provide a means to suppress or extinguish a fire in an emergency situation, or at the very least limit the spread of fire from one area to another while the Fire Department is on its way to the site.

There are four types of sprinkler systems to suit differing protection requirements:

Wet systems are the most common and are typically found in office buildings, retail establishments, and climate controlled warehouses.

Dry systems are used in environments subject to freezing such as loading docks.

Pre-action systems are typically activated by automatic early warning detection and provide an added safeguard against unwanted release. Applications include frozen storage freezers and computer rooms.

Deluge systems utilize open sprinkler heads for hazards requiring the entire system to discharge at the same time for areas like outdoor transformers and fuel loading racks.

In general terms, Sprinkler Systems consist of Heads (which open to allow the water to reach the fire), a piping delivery network to carry the water to the Sprinkler Heads and an Alarm Check Valve intended to separate municipal water supply from the piping delivery network. In most buildings, the Sprinkler Systems are integrated with the building fire alarm system such that activation of a switch connected to the Sprinkler System (Flow Switch, Low Pressure Switch, and Tamper Switch) will also initiate the alarm, alert and notification aspects of the fire alarm system in the emergency situation.

Geelong Fire Services provides Annual Inspection & Testing, as well as proactive and reactive repair work to correct deficiencies in existing sprinkler systems, plus 24/7 Emergency Service Calls.

A variety of suppression system agents are available to suit any application:

  • Gaseous Systems (FM200 / Novec 1230 / Argonite / Proinert /CO2)
  • Waterspray Systems (Medium and High Velocity)
  • Pre-engineered Foam Systems / Wet Chemical / Dry Chemical Systems
  • Foam Systems (Low / Medium / High Expansion)
  • Explosion Detection / Suppression

Typical application are:

  • Computer Rooms (FM200 / Novec 1230 / Argonite / Proinert)
  • Substations (FM200 / Novec 1230 / Argonite / Proinert)
  • Switchrooms (FM200 / Novec 1230 / Argonite / Proinert)
  • Gas Turbine Enclosures (CO2)
  • Diesel Generator Enclosure (CO2)
  • Kitchen Hoods (Wet Chemical)
  • Paint Booths (Dry Chemical)
  • Lube Oil Tanks (Low Expansion Foam)
  • LPG Storage Tanks (Medium Velocity Waterspray)
  • Process Pumps (High Velocity Waterspray)
  • Transformers (High Velocity Waterspray)
  • Flammable Liquid Storage (Low Expansion Foam)

Clean Agent suppression systems (FM200, NOVEC 1230, Argonite, Proinert)

  • Provide waterless alternatives to sprinkler systems. Clean Agents are safe to breath and once discharged extinguish the fire rapidly and leave no residue.
  • They diminish the risk of downtime by detecting and extinguishing a fire in its earliest stages. Clean Agents are fast reliable, environmentally friendly, and require no clean up. This translates into minimal business interruption.
  • Clean Agents systems are used in areas that protect high values assets. Typical applications include computer rooms, telecommunications equipment, document storage areas and military ships.

Carbon Dioxide (CO2) suppression systems

  • Extinguish fire by removing the oxygen from the protected area. While they are environmentally safe and leave no residue they are not recommended for normally occupied areas because of the asphyxiating effect on people.
  • CO2 systems are extremely effective for many industrial hazards including chemical storage areas, electric generating plants, transformer rooms, turbines, food manufacturing processes and semi conductor wet benches.

Medium Velocity Waterspray systems

  • Mainly used for exposure protection from a fire elsewhere

High Velocity Waterspray systems

  • Extinguishes a fire in heavier oils but emulsifying the oils

Low Expansion Foam systems

  • Extinguishes a fire by producing a layer of foam over the surface of the fuel

High Expansion Foam systems

  • Extinguishes a fire by producing a large volume of expanded foam to completed enclosure the risk

Wet Chemical systems

  • Extinguishes a fire by reacting with the hot oil coating.

Geelong Fire Services is highly experienced at inspecting, servicing and installing all types of suppression systems.
