Fire Sprinkler Systems

How do they work?

Each sprinkler head contains a heat-sensitive element, these elements are designed to rupture at specific temperatures. If the temperature in the area exceeds the given threshold the element will break, opening the sprinkler head up and water will start to flow and control or extinguish the fire in the protected area.

Our automatic sprinkler systems:

• Mains water fed, under pressure
• Extinguishing mechanism is used purely for the removal of heat. The water which, on contact with the heat source, turns into steam, ultimately starving the fire of oxygen
• Automatic sprinkler system is activated by an individual heat sensor at every sprinkler
• When activated the consequent drop in water pressure is monitored by a control panel which immediately activates a pump in order to maintain the necessary pressure until manually shut down
• Sprinkler systems are suitable for numerous applications in a wide range of markets, and include the home, high rise blocks, and industrial, commercial and leisure buildings

Do I need a sprinkler system?

This is generally governed by the requirements of your insurance company. For example, the size, complexity and occupancy of the building may necessitate a sprinkler system be put in place to protect an extended fire escape route.

Domestic sprinkler systems are also becoming more popular as people see the benefit in protecting their possessions, however there is currently no legal requirement for these.

Do they need maintaining?

If you have a sprinkler system then it must be maintained on a minimum service interval of 6 months. Please contact us for a quotation for the service of your sprinkler system and fire pumps.

System Configuration

• The Wet Pipe System – filled with water up to the farthest sprinkler, and is suitable for frost-protected areas
• The Dry Pipe System – filled with water only as far as the dry pipe valve, beyond which is filled with compressed air, and is the advisable option in areas subject to frost.
• Pre Action System – The system is filled with air, with the water held back by an electronically operated valve. A fire detection system is then used to operate the electrically operated valve which allows water into the system prior to the sprinklers activating. This type of system is used in sensitive areas.
• Deluge System – Open pipework and nozzles to cover an entire area on the discovery of a fire. Can be operated either electronically or by an array of air-filled pipework with sprinklers used to detect the fire. Used in areas where the rapid spread of fire is likely.
