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.
