Residential Fire Sprinkler Systems
Residential Fire Sprinkler Systems are installed in (HMO's) Houses of Multiple Occupancy, Apartment Blocks, Care and Nursing Homes, Student Accommodation.
Residential occupancies for multiple occupation not exceeding 20m in height include apartments, residential homes, houses of multiple occupancy (HMO’s), blocks of flats, boarding houses, aged persons homes, nursing homes, residential rehabilitation accommodation and dormitories.
The new regulations state that dwellings with more than 1 floor 4.5 meters above ground level can have a full sprinkler system as an alternative means of escape (Building Regulations Part B 2.7b). This avoids the requirement for a second separate staircase
The Fire Sprinkler System will be designed, installed and commissioned to the BS9251:2021 standards Category 2, the minimum design discharge density should be increased to 4mm/min for single head operation, or 2.8mm/min through each sprinkler operating simultaneously up to a maximum of 2 sprinklers in a single area of operation, with a 30 minute water supply.
BCK Fire Sprinklers uses only a few suppliers for our pipework, connections, valve sets, sprinkler heads, and covers as we install your system in accordance with BS9251:2021 Standards.
It is necessary to have an unmetered water supply that is at least 32 mm or larger in size along with a flow test to verify that the water supply is flowing at least 110 lpm into your property. Should the water supply be insufficient, it will be necessary to add a pump and tank.
If you haven't already, our team at BCK will request that you send us a floor plan of the property that needs a fire sprinkler system. These drawings must be in.pdf or.dwg format so that our estimators can see the layout of the property and determine how many sprinkler heads will be needed to protect it.
Before installation, BCK will email you an estimate. If it is accepted, we will work to complete a sprinkler design that you may submit to Building Control for approval. When the system is approved, BCK will talk with you about the ideal time to begin installation.
During the first fix stage, our engineers will install the sprinkler heads and piping. After the system is installed, they will test it under pressure and leave it there until we return to commission it.
When we come to commission the system, it will be after the painting and decorating is finished. We will install the cover plates that conceal the sprinkler heads in the ceiling, connect the fire sprinkler system to the water mains or the pump and tank, and make sure everything is operating properly by turning on the flow switch and allowing water to pass through the flow switch which will in turn activate the sounder alarm. The Fire Sprinkler System is then left in full working order and in a commissioned state.

Fire Sprinkler Covers
The fire sprinkler heads are covered by cover plates that are fitted during the commissioning stage. If these are painted, the heat won't be able to melt the solder, allowing the lid to come off, the fire sprinkler head to drop, and the fire to go out. Water will begin to flow through the flow switch when the fire sprinkler head activates, alerting you to the presence of a fire through the sounder alarm.
