Fire Sprinklers

Residential SprinklerFire Sprinkler Systems to BS 9251: 2014. 
Our company is dedicated to designing and installing domestic and residential fire sprinkler systems to not only meet but exceed BS9251:2014 throughout England and Wales.

Residental and Domestic Fire Sprinkler Systems.

Fire sprinklers in domestic properties have grown in demand over the last 10 years due more stringent Fire & Building Regulations. Building Regulations Approved document B can allow sprinkler systems to be used instead of other passive fire protection. For example: the removal of walls to allow open plan living, removal of secondary means of escape if the building is over 7.5m high, allows open stairways and more. To allow for these relaxations all domestic and residential sprinkler systems must comply with BS9251:2014.

As of 2016, Wales was the first country in the world to introduce legislation making it compulsory for all newly built houses and flats to be installed with fire sprinklers to BS9251:2014.

Sprinklers can also allow for some buildings to be constructed that would otherwise not get planning consent. For Example: Buildings with limited access for fire brigade.

With the rapid advancement of technology fire sprinklers have become barely noticable and aesthetically pleasing, only part visible is an almost flush white flat plate (as pictured).

Fire Sprinkler Pipework

Most of our sprinkler systems are installed with CPVC pipework. CPVC is the prefered choice throughout the domestic & residential sprinkler industry due to being UL and FM approved, having superb fire resistant qualities and very low frictional loss.

CPVC is solvent weld system that can be installed very quickly minimising the impact to the customer and reducing costs.

We can install sprinkler systems using a pressfit steel system, this is commonly used if the pipework is exposed / surface mounted.

Sprinkler System Water Supplies

There are three main ways to supply the water a sprinkler system needs to operate,

Mains fed – Direct from the water main. This is the most cost effective solution. Normally the water main has to be upgraded to minimun 32 mm supply.

Dedicated pump and tank – A storage tank and a booster pump can be used if the water mains is insufficient.

Shared boosted water supply
 – A pump and tank used for the buildings cold water supply can also be shared with the sprinkler system. This can be a cost effective solution.

Fire Sprinkler Installation Process
Design
 – Drawings are produced with sprinkler locations and pipework indicated. Hydraulic calculations carried out to determine system requirements.

1st fix – At this stage pipework is installed at the same time as the plumbing and electrical trades prior to boarding the ceilings. Sprinkler heads are set to the right height and left with protective caps. System is fully pressure tested to 1.5 times working pressure to ensure there are no leaks.

2nd fix and commission – This stage is carried out close to project completion, ceilings should have had final coats of paint and water supplies live. We then remove protective caps and install white finished cover plates. We install the water supply equipment. Lastly we carry out final commissioning tests.

Certification

Upon completion a certificate of compliance in accordance with BS9251:2014 will be issued and O+M documents will be given to the customer.
