ADB1 UNSPECIFIED Para:E3 Design of sprinkler systems

Where required, sprinkler systems should be provided throughout the building or separated part,
unless acting as a compensatory feature to address a specific risk. They should be designed and
installed in accordance with the following.
a. For residential buildings, the requirements of BS 9251.
b. For non-residential buildings, or residential buildings outside the scope of BS 9251, the
requirements of BS EN 12845, including the relevant hazard classification together with
additional measures to improve system reliability and availability as described in Annex F of the
standard.
NOTE: Any sprinkler system installed to satisfy the requirements of Part B of the Building
Regulations should be provided with additional measures to improve system reliability and
availability and is therefore to be regarded as a life safety system. However, there may be some
circumstances in which additional measures to improve system reliability and availability specified
in Annex F of BS EN 12845 are inappropriate or unnecessary.
