This document specifies four types of apparatus to warn and/or alarm in the event of an escape of town gas, natural gas or liquefied petroleum gas (LPG), Hydrogen and flammable refrigerant gases: — Type A apparatus – provides a visual and audible alarm and an executive action in the form of an output signal that can actuate directly or indirectly a shut-off device and/or other ancillary device in the event of an escape of town gas, natural gas (LNG) liquefied petroleum gas (LPG) and Hydrogen gases; — Type B apparatus – same as Type A but provides a visual and audible alarm only; — Type C apparatus – provides a visual and audible alarm and an executive action in the form of an output signal that can actuate directly or indirectly a shut-off device and/or other ancillary device in the event of an escape of flammable refrigerant gas A2L, A2 or A3 as classified in other International Standards, e.g. ISO 817; — Type D apparatus – intended to be installed where there can be a source of danger to the public, designed for continuous operation in fixed installations in non-classified explosive atmosphere premises (where the requirements for electrical Ex-safety are not requested). Intended for any flammable gases. Typically Type D apparatus are available with analogue or digital output, designed as detection system. These systems are regularly maintained by competent persons and/or have a protection of IP44 or higher. For type D apparatus, EN 60079-29-1 is applied. See Annex C for further clarification on the apparatus types and their application.

This guide is intended to cover any type of domestic or residential accommodation, including leisure accommodation vehicles such as touring and static caravans, and motor homes; and recreational craft such as canal barges. Some static caravans are used as permanent dwellings; in such cases EN 50291 1 is appropriate. For all other types of caravan, EN 50291 2 is appropriate. This guide is read in conjunction with EN 50291 1 and EN 50291 2 together with any additional relevant national or local regulations. This document refers to the installation of two types of apparatus: a) Type A apparatus, to provide a visual and audible alarm and an executive action in the form of an output signal that can be used to actuate directly or indirectly a ventilation or other ancillary device; b) Type B apparatus, to provide a visual and audible alarm only. This document excludes apparatus for the detection of combustible gases (see EN 50244) and for industrial installations or commercial premises.

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. 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 apparatus 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. 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 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 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.

Legal consequences resulting from performance measurements makes for strict requirements for the apparatus used (see EN 50379-1:2012, normative Annexes B and C [4]). NOTE 6 EN 50379-3 [6] is for apparatus intended to be used for non-statutory applications, which allows for reduced performance requirements for the portable electrical apparatus. NOTE 7 This Technical Specification deals with the determination of levels of combustion gases carbon monoxide (CO), carbon dioxide (CO2) and/or oxygen (O2) in combustion products from gas-fired appliances. Combustion products from gas-fired appliances will contain nitrogen oxides (NOX), predominantly nitrogen monoxide (nitric oxide, NO) and nitrogen dioxide (NO2). This Technical Specification does not deal with the measurement of combustion products such as NOX and aldehydes.
