Residential Sprinkler Systems – Category 2, 3 & 4 Sprinklers

Since updates to BS 9251 in 2014 and more recently in 2021 all fire sprinkler systems in residential properties are classed as residential sprinklers. Previously sprinklers were divided into domestic and residential sprinklers now they are divided into category 1, 2, 3 and 4 residential sprinklers.  Category 1 covers sprinklers in private homes, (previously domestic sprinklers) see more info on our page about home fire sprinklers.

Category 2, 3 & 4 residential sprinkler systems are designed for buildings where more than 1 family lives i.e. multiple occupancy properties, flats, care homes etc. These are divided into three categories:

Category 2 Fire Sprinklers

Residential Sprinklers 

Designed to protect homes and their occupants from the spread of fires. Here are some key points about residential sprinkler systems:

• Function: Residential sprinkler systems automatically detect, slow the spread and even extinguish fires in homes. They release water when a fire is detected.
• Components: A typical residential fire sprinkler system includes sprinkler heads, a water supply source (often a dedicated water tank or connection to the mains), pipes, and a control panel.
• Activation: Sprinkler heads are activated individually when they reach a certain temperature, caused by the heat of a fire. This helps contain and suppress the fire at an early stage.
• Coverage: The number of sprinkler heads and their placement depend on factors such as the size and layout of the house. They are strategically positioned to provide effective coverage.
• Benefits: Residential sprinkler systems can save lives and minimize property damage in the event of a fire. They are highly effective in controlling fires before they escalate.
• Maintenance: Regular maintenance and inspections are essential to ensure the system’s proper functioning.

Residential fire sprinkler systems enhance fire safety in homes. If you have specific questions or need more detailed information about these systems, feel free to ask.
