detection and alarm systems for buildings, Code of practice for the design, installation
and maintenance of fire detection and fire alarm systems in dwellings.
The minimum standard of protection recommended in the 2004 edition of BS 5839-6 is,
for new dwellings, that smoke alarms should be provided within the circulation areas
of most single-family dwellings and small houses in multiple occupation (HMOs), and
that heat alarms should be provided in the kitchen and the principal habitable room
(eg, the lounge).
The Standard recommends that smoke alarms and heat alarms installed within new
single-family dwellings and small HMOs are mains powered with, in addition, a standby
power supply in the form of a battery or capacitor.
There are six Grades of system in the Standard. The Grades identify the equipment
incorporated. Grades A, B and C are systems that include fire detectors, alarm devices
and central control equipment. Grades D and E are mains-powered smoke alarm
systems (as summarised in Table 1). A Grade F system includes a battery-powered
smoke alarm.
Categories of system (used to describe the principles of operation) in the Standard are
summarised in Table 2.
In the context of fire detection and alarm systems in dwellings, attention is drawn to the
relevant requirements of national building regulations and, in the case of small HMOs,
to the relevant housing legislation.
Guidance on fire alarm requirements in building regulations is given in Approved
Document B in England and Wales, the Technical Standards that support the relevant
building regulations in Scotland, and in Technical Booklet E in Northern Ireland.
