BS5839 Part
6 2004 - Fire Alarm System Installations in Dwellings
The British Standard Associated
with Fire Alarm System Installations in Dwellings is BS5839 Part 6
2004. This part of the British Standard is split up into 3 categories of
systems. These categories are as follows:-
- LD1 - Alarms in all circulation
spaces that form part of escape routes and all areas where a fire might
start, but not bathrooms, shower rooms or toilets
- LD2 - Alarms in all circulation
spaces that form part of escape routes and rooms or areas that present a
high fire risk
- LD3 - Alarms in circulation
spaces that form part of escape routes
The category of
system that should be installed in a building is often defined by Councils,
Insurance Companies, Fire Officers, Building Control and many others.
The above
categories indicate the category of system that should be installed.
Further to this information different grades of system may be specified.
These are as follows:-
- Grade A - A full system with
control and indicating equipment installed to BS 5839: Part 1
- Grade B - Detectors and
sounders using simpler specified equipment
- Grade C - Detectors and
sounders or alarms with central control
- Grade D - Mains powered alarms
with an integral stand-by power supply
- Grade E - Mains powered alarms
with no stand-by power supply
- Grade F - Battery powered
alarms
These grades are
used in conjunction with the category type, to indicate what type of system
should be installed within the property. For example if an LD2 Grade A
system is requested, this would require a system with alarms in circulation
areas that form escape routes and high fire risk areas with the equipment with
control and indicating equipment compliant to BS5839 Part 1.
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.
ReplyDeleteIt 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 which 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.
