A basic fire sprinkler system includes pipes that carry the water supply to a series of sprinkler heads. They are strategically placed in the ceiling of each room. Pressure valves built into the network of piping helps to control the water pressure and the rate of flow of the water through the system.
Commonly used as a primary fire protection solution for almost 150 years, automatic sprinkler systems are highly effective.
There are many different types of sprinkler systems, which are listed.
The most common type of system, found in a variety of different premises. This system is constantly charged with water.
For areas susceptible to freezing such as a car park, these systems contain a valve which ‘hold back’ the supply of water and pipework that is permanently charged with air.
Containing sprinkler heads or nozzles that are open, a deluge system operates by an activation of smoke/heat sensors. Found in power plants, aircraft hangars and chemical storage.
Similar to a dry pipe system in that the pipework is charged with air, a pre-action utilises a primary sensory system to charge the system with water, effectively turning it into a wet type system. Found in cold storage warehouses or areas containing valuables such as museums.
Installed where there is risk of a liquid fire from flammable liquids. Found in aircraft hangers and various types of warehouse premises.
Fire hydrants are a connection point by which firefighters can tap into a water supply. It is a component of active fire protection, underground fire hydrants have been used in Europe and Asia since the 18th century.
Gas suppression is ideally suited in server rooms where other forms of firefighting may cause water damage or loss of data, or in electrical rooms where water would pose a risk to life. By using inert gases and chemical agents it means that your employees and assets are safe in all circumstances.
Providing a mains feed via an electric or diesel pump to ensure continuous water pressure when fighting a fire, pumps rooms form part of a large sprinkler installation where a towns mains supply is not sufficient enough and water storage tanks are required.
Any buildings over 50 metres will require a wet riser to be installed in accordance with BS9990/2015.
This operates in the same way as a Dry Riser, however, the pipe is constantly charged with water and has a water storage tank as well as duty and standby pumps to boost the water to heights of above 45m.
Wet risers should be inspected and tested regularly to ensure equipment is functioning correctly and ready for use. It is recommended that the system is visually inspected every 6 months and serviced annually to ensure that the equipment is ready for immediate use in an emergency.
A dry riser is an empty pipe that can be externally connected to a pressurised water source by firefighters. It is a vertical pipe intended to distribute water to multiple levels of a building or structure as a component of the fire suppression systems.
Dry risers are used when the water pressure of a building wouldn’t be enough for fire suppression and in unheated buildings where the pipes could freeze. In the UK, dry risers must allow fire engine access within 18 m of the dry riser inlet box.

High and Low Water Mist Systems
A water mist system is a fire protection system which uses very fine water sprays (i.e. water mist). The small water droplets allow the water mist to control, suppress or extinguish a fire.
The use of water mist fire suppression, when compared to the use of gaseous agents and traditional sprinkler systems, has revealed advantages such as:
• Immediate activation.
• High efficiency in the suppression of a wide variety of fires.
• Environmentally sound characteristics.
• Minimised water damage
