Code of practice for design, installation, commissioning and. [ BS 5839-1 has been pivotal in the application of fire detection and alarm technology for almost 30 years. Here Colin Todd outlines its most recent provisions in the context of holistic fire safety design. For many years, BS 5839-1 has been one of the best selling of the many thousands of British Standards published by the British Standards Institution (BSI). Perhaps it is not surprising that this should be so. The legal requirement for an electrical fire alarm system in the vast majority of non-domestic premises has been well established for several decades. Codification of design and installation criteria go back to 1951, when a code of practice was produced by a committee within BSI that dealt with other matters, including time clocks. That code of practice lasted 21 years before it was replaced by CP 1019 in 1972. Even then, fire alarm systems were regarded as a simple matter of electrical engineering, and the code of practice was produced by an electrical engineering committee in BSI. The first fire alarm code of practice produced by a specialist fire standards committee was BS 5839-1: 1980. That code of practice was produced prior to the introduction of the modern addressable fire alarm system. A history of archaeological thought pdf free. By the 1980s, however, fire alarm technology was beginning to move at a fast pace, reflecting the speed at which electronics and micro-processor technology was developing. By the time a completely revised version of BS 5839-1 was published in 1988, five amendments had already been made to the 1980 version of the code of practice. The 1988 Code of Practice was quite revolutionary and forward thinking in its recommendations, particularly those relating to the then new technology addressable systems, for which fundamental new design principles were established for the first time. By then, BS 5839 Part 1 had established itself as essential reading and reference for anyone involved in the design of fire alarm systems, the installation and commissioning of systems and the routine maintenance or repair of systems. Accordingly, the readership comprised a vast army of not only fire alarm specialists but also consulting engineers and electrical contractors. The 1988 version of BS 5839-1 was not without its problems. It had become the ‘bible’, against which designers carried out their designs and enforcing authorities specified their requirements. However, as a code of practice, BS 5839-1 had never been intended to be prescriptive enough for the definitive compliance that this necessitated, particularly when installations were audited under third party certification schemes such as LPS 1014 and, later, BAFE SP 203. Much of BS 5839-1 had been written almost as a text book with useful information, but ambiguity in the implications of the information in terms of system design. Moreover, the code was peppered with phrases such as “consideration should be given to. “, creating arguments as to whether or not a measure was necessary for compliance. The 2002 version of BS 5839-1 adopted a bold and fundamental change in format. The code of practice was written in “practice specification” format, in which explanatory text is totally separated from specific recommendations. This format is a very useful halfway house between a traditional code of practice, which is not intended to be interpreted as a specification, and a typical standard for a product, which would contain definitive requirements. While BS 5839-1 does not actually make any ‘requirements’, as it remains simply a code of practice with recommendations for the guidance of the wise and blind obedience only of the foolish, the recommendations are ‘auditable’, since they are short, definitive and individually numbered. This has had many benefits, including the possibility of better compliance by designers and contractors, more meaningful certification of systems, fewer disputes regarding interpretation and better recognition that ‘variations’ from the recommendations are perfectly acceptable – provided they are based on sound engineering judgment and are agreed by all interested parties. New technology Many technical changes were also incorporated to take account of new technology (e.g. Carbon monoxide fire detectors), simplify design and relax recommendations that had been found to be unnecessarily onerous in practice.
