Fire Sprinkler System

A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price.[1] Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings completely protected by fire sprinkler systems, over 96% of fires were controlled by fire sprinklers alone

Fire Hydrant System

Fire Fighting Hydrant Systems are the most commonly used systems, in many residential and industrial buildings. If you have ever seen a “Red” colour pipe, circulating around a building or factory, you have seen a Fire Hydrant Pipe. In most news clippings about a fire, you can see a fireman shooting water up to 8stories high or more, that fire man is using the Fire Hydrant System. Such is the power of the Fire Hydrant System that water can be shot right up to 8 floors, directly into the fire.

Dry Pipe System

A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. This air holds a remote valve, known as a dry pipe valve, in a closed position. Located in a heated space, the dry-pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate. Once this happens, the air escapes and the dry pipe valve releases. Water then enters the pipe, flowing through open sprinklers onto the fire.

Deluge System

A deluge system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system through actuator. The detection system is installed in the same area as the sprinklers. When the detection system is activated water discharges through all of the sprinkler heads in the system. Deluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge systems are needed where high velocity suppression is necessary to prevent fire spread.

In addition to the application of water some deluge systems will incorporate the use of a foam concentrate to mix with water and form a foam solution which can then provide a protective blanket of foam to help control the development of a fire. Water or Foam Deluge systems are used in the protection of large Aircraft Hangers as one primary means of fire protection.

Pre-Action System

Pre-action fire sprinkler systems employ the basic concept of a dry pipe system in that water is not normally contained within the pipes. The difference, however, is that water is held from piping by an electrically operated valve, known as a pre-action valve. Valve operation is controlled by independent flame, heat, or smoke detection.

Two separate events must happen to initiate sprinkler discharge. First, the detection system must identify a developing fire and then open the pre-action valve. This allows water to flow into system piping, which effectively creates a wet pipe sprinkler system. Second, individual sprinkler heads must release to permit water flow onto the fire.

In some instances, the pre-action system may be set up with a double interlock in which pressurized air or nitrogen is added to system piping. The purpose of this feature is two-fold: first to monitor piping for leaks and second to hold water from system piping in the event of inadvertent detector operation. The most common application for this system type is in freezer warehouses.

Foam Water Sprinkler System

Foam systems are used whenever there is a possibility of a liquid fire. Foam fire sprinkler systems operate by mixing a foam concentrate at specific proportions with water to create a foam blanket that smothers a fire. The distribution of a foam blanket over a flammable liquid will extinguish a fire by eliminating the fire's oxygen supply and provide a cooling effect on the burning fuel.

Foam systems used in place where Flammable Liquid Storage, Processing Area, Refineries, Aircraft Hangars, Heliports, Jet Engine Test Facilities, LNG Storage & Marine.

Water Spray System

"Water spray" systems are operationally identical to a deluge system, but the piping and discharge nozzle spray patterns are designed to protect a uniquely configured hazard, usually being three-dimensional components or equipment. The nozzles used are usually selected for a specific spray pattern to conform to the three-dimensional nature of the hazard. Examples of hazards protected by water spray systems are electrical transformers containing oil for cooling or turbo-generator bearings. Water spray systems can also be used externally on the surfaces of tanks containing flammable liquids or gases (such as hydrogen).

Fire Extinguisher System

A fire extinguisher, flame extinguisher or simply an extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure containing an agent which can be discharged to extinguish a fire.
