Design, installation and maintenance ( incorporating Corrigenda August 2009 ). Part 2. Technical Bulletins Part 3. Supplementary information Index Foreword The LPC Rules for automatic sprinkler installations have a distinguished pedigree and this latest part of the work continues the tradition. The history of sprinklers in the UK started almost two centuries ago. One of the earliest sprinkler systems was installed in 1812 at the Theatre Royal, Drury Lane, London. From these tentative beginnings, and with the active encouragement of insurance companies, the development of sprinklers and the installation of sprinkler systems burgeoned. It was not for another three quarters of a century, in 1885, that John Wormald of the Mutual Fire Insurance Corporation, composed a set of sprinkler Rules ;. measures for the design and installation of sprinkler systems.

8 In 1888, these Rules were published in London by the insurance companies' Fire Offices' Committee (FOG). The 29th and last edition of the FOC Rules was published in 1969. In 1952, with the approval and collaboration of the FOC, the British Standards Institution drew heavily upon the content of the FOC Rules to produce its Code of Practice for sprinkler systems. That Code was enlarged and superseded by BS 5306-2: 1979: Code of practice for fire extinguishing installations and equipment on premises ( sprinkler systems). The growing importance of sprinklers as a means of protecting people and premises from the hazard of fire led to the elaboration of the1979 standard into a document which could be cited for legislative purposes. In 1990, the British Standards Institution issued BS 5306-2: 1990: Fire extinguishing installations and equipment in buildings: Specification for sprinkler systems. That document embodied in full the requirements of the 29th edition of the FOC Rules , together with unpublished amendments thereto.

9 The activities of the FOC were acquired by the Loss Prevention Council (LPC) on its formation in 1985. In 1991, the LPC undertook the publication of its LPC Rules for automatic sprinkler installations, incorporating the text of BS 5306-2 together with a growing series of Technical Bulletins (eventually more than 30 of them). At about the same time as the 1991 Rules were issued by the LPC, the Comite Europeen de Normalisation (CEI\l) embarked upon the preparation of a set of European sprinkler Rules , the UK. version of which were published by BSI in August 2003 and re-issued in 2004. This present volume, published by the Fire Protection Association, contains the text of the latest version of bs en 12845: 2004 + A2: 2009 : Fixed firefighting systems. automatic sprinkler systems. Design, installation and maintenance, together with explanatory bulletins, under the title LPC Rules for automatic sprinkler installations 2009 incorporating as EN 12845. Users of the LPC Rules benefit in a number of ways: they can be assured that the Technical Bulletins, developed through RISCA uthority, have had input from sprinkler system experts and from fire engineering practitioners from insurance companies.

10 Those involved in producing the LPC Rules have many years of experience of working on the earlier FOC and LPC Rules ;. the loose-leaf format (with its CD ROM backup) ensures continuous updating of the reference information;. the format permits the addition of information about new system developments as they arise;. by joining the subscribers' Priority Update Register, users can rely upon early and reliable provision of updated material. This latest version of the LPC Rules is a comprehensive work of reference for anybody with a professional involvement in designing, specifying or installing sprinkler systems in Europe. It is commended without reservation.
