Page 3: Introduction
INTRODUCTION When first introduced in 1995, the BS 5839: Pt.6 Code of Practice became the most important set of recommendations ever made on fire safety in the home. It had an immediate impact on architects, system designers, installers and landlords in the private or public sector, all of whom were required to familiarise themselves with these important recommendations. -
Page 4: Fire Safety - Statistics
FIRE SAFETY - THE STATISTICS According to the latest UK figures the majority - over three quarters - of all fire casualties occur in the home. Until the introduction of BS 5839: Pt.6, business and commercial premises were the subject of far more stringent fire safety regulations than residential dwellings. -
Page 5: The Essential Changes To Bs 5839: Pt.6: 2004
THE ESSENTIAL CHANGES TO BS 5839: Pt.6: 2004 – AT A GLANCE THE DOCUMENT ITSELF Each clause of the document is now split into 2 parts. Firstly, there is the commentary – in italics – this sets out the reasoning behind what at first sight may appear to be arbitrary recommendations. -
Page 6: Wireless Systems
OTHER ALARM TYPES For the first time, BS 5839: Pt.6 now covers CO fire alarms and multi-sensor alarms. Heat alarms are given far more importance, as you will have noted from the New Build changes above, for example. Heat Alarms should always comply with BS 5446: Pt.2. -
Page 7: Bs 5839: Pt.6 - An Introduction
BS 5839: Pt.6 - AN INTRODUCTION BS 5839: Pt.6 is not intended for householders themselves, but to provide guidance and recommendations for architects and other building professionals, enforcing authorities, contractors and others responsible for implementing fire precautions in buildings. The Code of Practice should not be quoted as if it was a specification and the standard itself warns that particular care should be taken to... -
Page 8: System Design - Risk Analysis
SYSTEM DESIGN - FIRE RISK ASSESSMENT How can a system be designed to meet the latest standards? The Code recommends that a system is designed – where reasonably practicable - based on a fire risk assessment of the property. This needs to take into account: •... -
Page 9: Fire Risk - Where Do Fires Start
FIRE RISK - WHERE DO FIRES START? ust over half of all fatalities occur in the room where the fire breaks out; in HMOs, this rises to 60%. The Code notes that, in the United Kingdom, some 40% of all fatal fires start in living rooms or dining rooms, whereas 30% of fatal fires start in bedrooms. -
Page 10: Property Protection
Interestingly, the Code acknowledges that people on a low income are more at risk than other groups, which is borne out by statistics from the British Crime Survey. They may not be able to afford to replace batteries in smoke alarms and the Code consequently points out that ‘a more reliable power supply for the fire detection and alarm system is... -
Page 11: System Planning
MAINS POWERED SMOKE ALARMS - GRADE E The Code states that mains powered smoke alarms are potentially more reliable and are recommended to be installed in existing dwellings occupied by people who are unlikely to be able to change a smoke alarm’s battery. -
Page 12: Quality And Compatibility
QUALITY & COMPATIBILITY The quality of equipment installed is a factor that needs to be carefully considered. The Code states that, in general, all components should conform to relevant British Standards and should have undergone type testing to those Standards. Suppliers should preferably have approval to a recognised quality approval scheme such as the relevant BS EN ISO 9000 series standard. -
Page 13: Selecting The Right System
SELECTING THE RIGHT SYSTEM How do you choose which grade of system to install? The Code states that the grade of system that should be installed depends “on the nature of the dwelling, the level of the fire risk and the characteristics of the occupants.”... -
Page 14: Choosing Which Alarms To Use
CHOOSING WHICH ALARMS TO USE BS 5839: Pt.6 also looks in depth at the different kind of fire alarm sensors on offer. Sensibly, it points out that there is no single type of alarm that is most suitable in all cases and the final choice of which type of alarm to use will depend on individual circumstances. -

Page 16: Audibility
AUDIBILITY Audibility is another factor to be considered. The Code comments that ideally, an alarm system should be capable of producing a sound level of 75dB(A) at the bedhead, but that this is unlikely to be achieved unless there is a sounder/smoke alarm in the bedroom itself. -
Page 17: Wiring Smoke Alarms
A convenient and reliable alternative to hard wired interconnection is now readily available in the form of RadioLINK from Aico (see page 22). CERTIFICATION AND PAPERWORK The installer should certify that the installation conforms to BS 5839: Pt.6 for the correct Category and Grade of system. -
