Fire is devasting and can rip through a building at frightening speed. But you can provide 24 hour protection by installing a sprinkler system that can stop a fire the second it breaks out.
The number is nozzles required is depenedent upon the size of the room in which they are installed. An average-sized room will only need one sprinkler which works by breaking up the stream of water into a fine spray. A cap seals the waterway until a fire is detected.
If a fire breaks out hot air and gases rise to the ceiling and upon reaching the nearest sprinkler, heating the seal on the waterway. The cap will fall away and the sprinkler will be activated, spraying water over the fire. The water will immediately cool the hot gases and therefore prevent other sprinklers activating. Multiple sprinklers will only activate if hot gases will reach the next nearest sprinkler, limiting water damage to the premises. Responding fire fighters will only shut off the sprinkler once they are sure that the fire is completely out.
In larger buildings, such as warehouses, factories or large open
plan offices, more than one sprinkler may be necessary. In
residential settings, there is less likelihood of more than one
sprinkler being activated.
Domestic Sprinkler Systems
BS9251 defines a domestic premises as individual dwelling for occupation as a single family unit such as individual dwelling houses and individual apartments with a maximum individual room size of 40m². In such premises, sprinkler systems are designed to operate a maximum of 2 heads simultaneously in any one room. The systems pipe size will normally range from 28mm and 22mm with a typical incoming water service pipe of 32mm.
Sprinkler Systems can be installed using copper press fit or C-PVC, neither method of which require the use of any heat or naked flame. The risk of a fire is eliminated and installation time is reduced.
All our sprinkler systems use WRAS (Water Regulations Advisory Scheme) approved components and, in accordance with local water authority by-laws, have a check valve installed as standard. They also require only a 240v A.C. dedicated single phase electrical supply.

Residential Sprinkler Systems
BS9251 defines a residential premises as a dwelling of multiple occupancies such as apartments (including common areas), residential care homes, dormitories and houses of multiple occupancy (H.M.O’s) with a maximum individual room size of 180m². n such premises, sprinkler systems are designed to operate a maximum of 4 sprinkler heads simultaneously in any one room for a minimum of 30 minutes. The Sprinkler Systems pipe size will normally range from 54mm to 22mm with an incoming water service pipe of 63mm.
Installed using copper press fit or C-PVC, no heat or naked flame is required which eliminates the risk of a fire and significantly reduces installation time.
All our sprinkler systems use WRAS (Water Regulations Advisory Scheme) approved components and, in accordance with local water authority by-laws, have a check valve installed as standard.
If a sprinkler systems is to be installed in a nursing or residential
care home, it may require a 440v three phase supply with U.P.S. (uninterruptible power supply) depending on pump demand. Some higher hazard projects such as `life safety’ systems may even require a stand by pump.
