BS 5839 Part 1

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 is a standard published by the British Standards Institution. BS 5839-1:2013 supersedes BS 5839-1:2002+A2:2008, which has been withdrawn.

BS 5839 Part 1 provides recommendations for the planning, design, installation, commissioning and maintenance of fire detection and fire alarm systems for non-domestic premises. Recommendations for fire detection and fire alarm systems in domestic premises are given in BS 5839-6. It does not recommend whether or not a fire detection and alarm system should be installed in any given premises, nor does it provide any exceptions for non-domestic premises which are under construction.

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.

BS 5838 Part 1 does not cover systems whose primary function is to control or extinguish fire (such as sprinklers or automatic extinguishing systems), but does cover the secondary alarm signal generated by such systems. It also does not cover voice alarm systems (which are separately addressed in BS 5839-8), or systems that integrate fire alarm functions with non fire related functions. It also does not cover manually or mechanically operated notification devices, such as hand-cranked bells.

The NHS Estates publications HTM 05-03 Part B (in England and Wales) or SHTM 82(in Scotland) provide recommendations for fire detection and fire alarm systems in hospitals.

System components should comply with the appropriate EN 54 family part, developed by British Standards Institution as BS EN 54-.
