BS EN 12845:2015A1:2019 BRITISH STANDARD Nationalforeword This British Standard is the UK implementation of EN 12845:2015A1:2019 incorporating corrigendum January 2016.

The UK participation in its preparation was entrusted to Technical Committee FSH/18/2 Sprinkler Systems. A list of organizations represented on this mittee can be obtained on request to its secretary. The revision of EN 12845 took some time in development and as a result the UK mittee feels it may not reflect current sprinkler technology and practice. National Annex NA identifies some areas of concern and also provides guidance and material related to UK practice. A sprinkler system designed installed and maintained in accordance with this standard is capable of providing protection of property and for the safety of people including firefighters should a fire occur in sprinklerprotected premises. It should be noted that this standard no longer uses the term life safety. For the avoidance of doubt and to clarify issues that have frequently arisen when sprinkler systems are called for to satisfy national regulations including any references to life safety such requirements are now found in Annex F: Additional measures to improve system reliability and availability. It is anticipated that this annex will make it clear that additional ss aa o essaauonsn ae se e nba response or prevent the periodic closure of protected occupancies when a sprinkler system is impaired. Attention is drawn to the LPC Rules for Automatic Sprinkler Installations which incorporate the provisions of BS EN 12845.
