This Clause of EN 50194 is replaced by:
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.
This 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 and/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 apply.
NOTE 2 Apparatus tested in accordance with the EN 61779 series of standards will not necessarily comply with
this standard.
