BS 5839 Part 1 Fire detection and fire alarm systems for buildings – Part 1: Code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises[1] is a standard published by the British Standards Institution.
It s the first of 9 parts in a series on national standards relating to fire alarms.
The term "fire detection and fire alarm systems" is a fairly wide definition, including small systems whose field devices consist only of sounders and manual call points, to complex networked systems with a large number of automatic fire detectors, manual call points and sounders, connected to numerous networked control and indicating panels.
It also does not cover manually or mechanically operated notification devices, such as hand-cranked bells.
Code of practice for the design, installation, commissioning and maintenance of emergency voice communication systems, part 9 in the series of national standards, covers the design, installation and maintenance of emergency voice communication systems where they form part of a fire safety strategy.
