What does the British Standard BS 5839:
Part 6: 2004 Recommend?
This is the definitive code of practice to which Architects, Building
Professionals, Enforcing Authorities, Landlords and Installers should refer
for recommendations on the design, installation and use of smoke
and heat alarms in the majority of domestic dwellings. Landlords in
both the public and private sector are considered to have a duty of
care to fit compliant smoke and heat alarms.

●
If a fire risk assessment shows the property or occupier
to be a high fire risk, increase the number of alarms
installed to meet the risk - e.g. follow new build
recommendations for an LD2 installation
●
All alarms should be interconnected
●
The sound pressure level of the
alarm signal measured at the
doorway of each bedroom
with the door open should
be at least 85dB(A)

If a fire risk assessment identifies a concern that the occupier
cannot or may not replace a battery, use mains alarms or mains
with battery back-up
●
If a fire risk assessment shows the property or occupier to be
a high fire risk, increase the number of alarms installed to meet
the risk - e.g. follow new build recommendations for an
LD2 installation
System Grades and Categories
Six different grades of fire detection systems are defined and -
generally speaking - the greater the fire risk the more comprehensive
the system should be. Briefly, the Grades 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
Three different categories of life protection systems are defined. Briefly
these are (starting at the highest):
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 Code emphasises that no one type of alarm is most suitable for all
applications. Consideration must be given to the most suitable type of
detection - optical, ionisation and heat (see page 4 for definitions
and usage).
