What we do:

Design Benefits of Fire Sprinklers

It is clear that fire sprinkles protect a property and can save lives, and this is a compelling reason for fitting them, however sprinklers also offer significant design benefits. Fitting fire sprinklers enables more open plan designs and reduces the need for fire doors and self closing doors. These design benefits can free up additional space in a building, increase the mobility of the occupants and make it a more pleasant environment to live in.

Some of the design benefits of sprinklers are:

  • Houses over 4.5m can be served by a single protected stair without the need for an alternative exit or the need for increased smoke detection
  • Guidance on fire service access can be increased, the maximum distance from the fire appliance to the building from 45m to 60m
  • Boundary distances for external fire spread can be halved
  • Self-closing doors are not required to bedroom doors in care homes
  • Care homes can increase the size of compartments or distance between doors

BS9991 includes trade-offs where fire suppression systems are installed. These include open plan flats and reduced requirements for lobbies. Although any design solution or trade-off will require a Fire Strategy.

Fire Sprinkler Types

There are 3 types of sprinkler delivery system, Mains Fed, Boosted Mains Fed and Pump and tank.

Mains Fed is a connection directly from the towns mains water supply. This must include back flow protections to prevent water from the sprinkler system re-entering the mains supply. Typically, a 32mm main will be the smallest pipe size that can be used for a risk category 1 system. Any Mains fed systems would need to be tested prior to installation to ensure sufficient flow and pressures available. Shared water supplies are possible but with additional requirements.

Boosted Mains Fed is a connection to a boosted water supply. Typically, in blocks of flats a tank of water will be pumped to guarantee pressure and flow of cold water services to the flats. This can be used for sprinkler supplies however specials measures must be in place to safeguard the sprinkler supplies and sometime prioritise them.

Pump and Tank supplies can be either solely for the sprinkler use or share the tank with other services. In shared use, there must be specific requirements met. Sprinkler tanks and pumps will be sized by the hydraulic calculations using the risk category run time and number of heads calculated. Tanks can vary from 1200L category 1 up to 9000L category 3. All tanks can have a reduced storage amount by using a proven infill from a mains backup.
