The standard is applicable to emergencies that require full or partial evacuation and those for whichthere is a need to keep people inside a building, safe from danger outside.

Emergency sound systems in large public buildings, venues and sports grounds are covered bythis British Standard as a specific case because these form a class of building or complex which hascertain parameters which define a particular need in terms of life safety.Cross References:BS EN IEC 62040-2:2018BS 5839-9:2011BS 7671:2018BS EN 62040-4:2013BS EN 60268-16:2011BS 5839-8:2013BS EN 50200:2015 BS EN 62040-3:2011PD CEN/TS 54-32:2015BS EN IEC 62040-1:2019BS EN 50171:2001BS EN 50849:2017BS EN IEC 60268-3BS ISO 8887-1:2017BS EN 61672-2:2013+A1:2017BS EN 54-24:2008BS EN 54-16:2008BS EN 54-4:1998BS EN 60268-5:2003+A1:2009
