This European Standard provides information on the selection, installation, use and maintenance of apparatus for the detection of combustible gas designed for continuous operation in a fixed installation in domestic premises as described in the EN 50194 series. This guide should be read in conjunction with any additional relevant national or local regulations.
The European Standard refers to the installation of two types of apparatus designed to operate in the event of an escape of town gas, natural gas or liquefied petroleum gas:
-
Type A apparatus – to provide a visual and audible alarm and an executive action in the form of an output signal that may actuate directly or indirectly a shut-off device and/or other ancillary device;
-
Type B apparatus – to provide visual and audible alarms only.
This guide is not applicable to the use of apparatus:
-
for the detection of toxic gases such as carbon monoxide, see EN 50292;
-
for industrial or commercial premises, see EN 60079-29-2.
