35、s for the audible alarm and associated red visual signal have been clarified; low battery, fault and End-of-life audible and visual warnings are given in an informative annex; An informative annex has been added for apparatus displaying low (Warning) CO levels; Requirements have been added for appar
36、atus using radio links; The sound output alarm requirement has been increased in line with the EN 14604 smoke alarm requirements.

BS EN 502911:2018EN 50291-1:2018 (E) 6 1 Scope This European Standard specifies general requirements for the construction, testing and performance of electrically operated carbon monoxide gas detection apparatus, designed for continuous operation in domestic premises
38、. The objective is to detect defective fossil fuel or solid fuel appliances so that they can be repaired or replaced. The function of the standard is not to monitor low levels of CO for health purposes. (Annex F gives recommendations for units displaying low (warning) CO concentrations). The apparat
39、us may be mains-powered or battery-powered. Such apparatus is intended to warn of an acute level of CO, enabling the occupant to react before being exposed to significant risk. Additional requirements for apparatus to be used in recreational vehicles and similar premises are specified in EN 50291-2.
40、 NOTE 1 For caravan holiday homes EN 50291-1 applies. This European Standard specifies two types of apparatus, these are: type A to provide a visual and audible alarm and an executive action in the form of a transmittable output signal that can be used to actuate directly or indirectly a ventilation
41、 or other ancillary device; type B to provide a visual and audible alarm only. NOTE 2 Both type A and type B apparatus can be interconnected. This European Standard excludes apparatus for: the detection of combustible gases, other than carbon monoxide itself (see EN 50194-1); the detection of CO in
42、industrial installations (see EN 45544-1, EN 45544-2 and EN 45544-3) or commercial premises; CO measurement for smoke and fire detection; CO measurement in carparks and tunnels.
