11、t of BS 5839 is published by BSI Standards Limited, under licence fromThe British Standards Institution, and came into effect on 31 May 2013. It wasprepared by Technical Committee FSH/12/1, Installation and servicing. A list oforganizations represented on this committee can be obtained on request to

12、 itssecretary.SupersessionThis part of BS 5839 supersedes BS 5839-6:2004, which is withdrawn.Information about this documentThis new edition introduces a number of technical changes. It does notconstitute a full revision of the document, which will be undertaken in duecourse. The principal changes i

13、ntroduced by this new edition are as follows.a) The scope of the standard has been extended to include not only theindividual dwellings within sheltered housing, but also the common partsand facilities within buildings used for sheltered housing.b) A smoke detector, rather than a heat detector, is n

14、ow recommended forinstallation in the principal habitable room(s) of new premises.c) Suitable carbon monoxide fire detectors are now recognized as analternative to smoke detectors in the principal habitable room(s) ofpremises.d) New recommendations are included to ensure that, in sheltered housing,f

15、ire alarm signals transmitted to an alarm receiving centre via a social alarmsystem cannot be delayed by other alarm signals originating from thepremises of fire origin or elsewhere.e) Addressable fire detection and fire alarm systems are recommended forsheltered housing in which detectors within dw

16、ellings are connected to thefire alarm system in the common parts.In the United Kingdom, around 80% of all fire deaths and injuries occur indomestic premises, over 300 deaths and around 9 000 injuries per annum. Manyof those who die are the most vulnerable in the community, namely elderly andsociall

17、y deprived people. The installation of a fire detection and fire alarmsystem in premises can substantially reduce the risk of death or serious injuryfrom fire. Indeed, the overall downward trend in annual fire deaths in domesticpremises since smoke alarms in domestic premises were first given recogn

18、ition inBS 5839-1 in 1988 is almost certainly attributable in part to the increasing use ofsmoke alarms.The level of deaths and injuries remains, however, above a level that societyregards as acceptable. It has been estimated that, in premises without smokedetectors, a substantial proportion of the

19、fatalities from fire could be avoided ifsmoke detectors were installed. The fatality rate in fires in premises in whichthere is no working smoke detector is between two and three times the fatalityrate in fires in premises in which a smoke detector is present and functionscorrectly.BRITISH STANDARDB

20、S 5839-6:2013ii The British Standards Institution 2013The installation of automatic fire detectors is required in new houses, flats andmaisonettes in order to satisfy building regulations. In existing houses inmultiple occupation, the installation of an automatic fire detection and firealarm system

21、is normally required by the relevant enforcing authorities. Thisgives rise to the need for a suitable code of practice, as BS 5839-1 does notcontain recommendations on domestic smoke alarms, nor does it address thespecial design requirements for fire detection and fire alarm systems in domesticpremi

22、ses.The guidance in this standard is intended for architects and other buildingprofessionals, enforcing authorities, designers and installers of fire detection andfire alarm systems and others responsible for implementing fire precautions indomestic premises.It has been assumed in the drafting of th

23、is part of BS 5839 that the execution ofits provisions will be entrusted to appropriately qualified and competent people.Use of this documentThis British Standard takes the form of guidance and recommendations. Itshould not be quoted as if it were a specification and particular care should betaken t

Itsrecommendations are expressed in sentences in which the principal auxiliaryverb is “should”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not p

27、page deliberately left blankiv The British Standards Institution 20131 ScopeThis part of BS 5839 gives recommendations for the planning, design,installation, commissioning and maintenance of fire detection and fire alarmsystems in domestic premises that are:a) designed to accommodate a single family

28、b) houses in multiple occupation that comprise a number of self-containedunits, each designed to accommodate a single family;c) sheltered housing, including both the dwelling units and the common areas.The recommendations apply to both new and existing domestic premises.Recommendations for routine

29、attention are also given.The systems covered in this part of BS 5839 range from those comprising a singleself-contained smoke alarm to systems of the type described in BS 5839-1. Therecommendations of this part of BS 5839 may also be applied to the firedetection components of combined domestic fire

30、and intruder alarm systems orfire and social alarm systems.This part of BS 5839 applies to forms of domestic premises, including bungalows,multi-storey houses, individual flats and maisonettes, mobile homes, shelteredhousing, housing providing NHS supported living in the community (as definedin Heal

31、th Technical Memorandum 88 1), mansions, shared houses and housesdivided into several self-contained single-family dwelling units. It does not applyto hostels, caravans or boats (other than permanently moored boats used solelyas residential premises), or to the communal parts of blocks of flats orma

32、isonettes. It does not apply to any premises used for purposes other than asdomestic premises (e.g. small shops, factories or similar premises used solely asplaces of work).This part of BS 5839 is intended for use by architects and other buildingprofessionals, enforcing authorities, installers and o

33、thers responsible forimplementing fire precautions in domestic premises. It is not intended foroccupiers, for whom advice is published by the Government1). However,recommendations are given for simple systems that may be installed bynon-specialists.The recommendations refer principally to fire detec

34、tion and fire alarm systemsinstalled for the purpose of life safety. However, recommendations are given forsystems that are also intended to protect property.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in thisdocument and are indispensable for its a
