BS 5839-9:2011, Fire detection and fire alarm systems for buildings. Code of practice for the design, installation, commissioning and maintenance of emergency voice communication systems, part 9 in the series of national standards, covers the design, installation and maintenance of emergency voice communication systems where they form part of a fire safety strategy. The 2011 version replaced an earlier 2003 version and reflects more recent regulatory and legislative requirements for building evacuation, including for people with a disability.
Note: This minimum category now only applies to owner occupied bungalow, flat, single-storey unit or maisonette with no floor level above 4.5m from ground level or owner-occupied two-storey house.Additional GuidanceWhy not download your free guide to the recent changes to BS 5839:6 and keep as a handy reference guide or share with a friend or colleague:
This music horn speaker is comprised of a high-efficiency weather-resistant horn and a high quality sound cone speaker, providing excellent speech and BGM clarity. It features ABS resin enclosure and stainless steel bracket for all weather durability. The CS-660BS-EB is certified to the European Standard EN 54-24: 2008 and International Standard ISO 7240-24: 2010, and is compliant with the British Standard BS 5839-8: 2008.
It should be noted that this part of BS 5839 does not cover systems whose primary function is to extinguish or control fire. Voice alarm systems, systems combining fire alarm functions with non-fire related ones, audible or visual way-guidance systems designed to complement the fire alarm function, and public emergency call systems (999 or 112) also fall outside the remit of this publication.Pages 3-10 of the Standard contain a useful glossary of relevant terms and definitions, from "addressable system" through to "zone plan", followed by a commentary on the various categories of system (pp 11-13). Referring once again to Annex A, these categories of system are linked to specific types of premises, so it may be helpful to consider what they actually involve.
It is important to ensure that, prior to the installation of a fire detection and fire alarm system, one organisation has accepted responsibility for compliance with the relevant section of BS 5839-1, i.e. Section 4: Installation, p 104-108. The Standard emphasises this point because it is possible for more than one party to be involved in the process of design through to installation, commissioning and final handover: for example, following on from the fire safety risk assessment, an independent designer may work up the system specifications and then feed them through to another organisation, e.g. a specialist fire alarm or electrical installation contractor, which is to be responsible for supplying and installing the system; or, even in situations where the entire project from start to finish has been commissioned through a single, specialist contractor, the actual installation work could well be sub-contracted out.
It is a complex process that can involve several different parties, so the Standard recommends that the system user appoints "a single, named member of the premises management to supervise all matters pertaining to the fire detection and fire alarm system". This places responsibility firmly in the hands of one individual, whose role is "to ensure that the system is tested and maintained in accordance with the recommendations of this part [Section 7: User's responsibilities] of BS 5839" (p 128). 2b1af7f3a8
