21、: This European Standard specifies test methods and performance requirements for electrical apparatus for the detection of combustible gases designed for continuous operation in a fixed installation in recreational vehicles and similar premises. NOTE 1 For caravan holiday homes EN 50194 applies. Thi
22、s standard specifies apparatus designed to operate in the event of an escape of liquefied petroleum gas (LPG) and/or petrol (gasoline) vapour and to provide 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 an
23、d/or other ancillary device (Type A of EN 50194). The standard excludes apparatus for the detection of toxic gases such as carbon monoxide (see EN 50291). Apparatus complying with this standard is not considered suitable for industrial or commercial installations for which EN 61779-1 and EN 61779-4
24、apply. NOTE 2 Apparatus tested in accordance with the EN 61779 series of standards will not necessarily comply with this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

40、ecting petrol vapour in applications such as the bilges of boats, where petrol is used as fuel. It is not applicable for the detection of vapour of diesel fuel. NOTE 101 Due to the low vapour pressure leaks of diesel fuel do not cause the risk of an explosion at ambient temperatures. The requirement
41、s for flammable gas detection as defined in EN 50194 apply equally to petrol vapour detectors. In this standard there are requirements that cover all apparatus. Additional application specific requirements apply to certain groups of recreational vehicles, such as boats. An apparatus which complies w
42、ith the requirements for recreational craft will automatically comply with the requirements for motor caravans and caravans. An apparatus which complies with the requirements for motor caravans will automatically comply with the requirements for caravans. The apparatus are designed for continuous op
43、eration. NOTE 102 When the vehicle is not in use the apparatus may be switched off in order to save the vehicles power supply or the internal batteries.
