It also does not cover manually or mechanically operated notification devices, such as hand-cranked bells. 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. 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.Д«S 5839 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 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. Recommendations for fire detection and fire alarm systems in domestic premises are given in BS 5839-6. 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.
