recommendations of BS 5839: Pt.6

more clearly understood, and to offer

advice on how to design, install and

maintain a system that meets the

requirements, with reference to the

2004 amendments.

At the same time, this guide is

designed to help answer the most

commonly asked questions about fire

detection; for example, ‘which types

of detector to use and where not to

use them’, and to help dispel the myth

that alarms are all the same. They are

not, as the Code itself is all too anxious

to point out.

This latest edition of the Guide has

been produced to take on board

new developments since the

introduction of the Code, both in

terms of fire statistics and evolving

fire safety technology.

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. Landlords in particular

needed to abide by these

recommendations, as legal liability with

regard to ‘duty of care’ would

undoubtedly become a serious issue

should a fire occur in an inadequately

protected property.

In short, BS 5839: Pt.6 became the

essential guide to providing adequate

fire protection in all dwelling types.

In September 2004, the Code of

Practice was extensively revised and

updated by the publication of 

BS 5839: Pt.6: 2004 and immediately

superseded BS 5839: Pt.6: 1995, which

is now withdrawn. The changes

therein are important and need to be

fully understood and appreciated by

all those with responsibility for fire

safety in domestic dwellings.

This document is intended as a guide

to BS 5839: Pt.6: 2004, highlighting the

changes that have come into effect

with the introduction of the 2004

edition while still remaining a

comprehensive guide to BS 5839 as 

a whole.

This guide is not intended as a

substitute for reading the Code of

practice itself. Instead, it’s designed

to help make the implications and
