21、1-2:2010EN 50291-2:2010 - 4 - 1 Scope 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 a fixed installation in recreational vehicles and similar p
22、remises including recreational craft. NOTE For caravan holiday homes EN 50291-1 applies. This European Standard specifies apparatus designed to operate in the event of an escape of carbon monoxide and to provide a visual and audible alarms only (Type B of EN 50291-1), or to provide visual and audibl
23、e alarms 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 50291-1). This European Standard excludes apparatus for the detection of combustible gases, other than carbon monoxide itself (see EN
24、 50194-1), for the detection of CO in industrial installations (see EN 45544-1, EN 45544-2 and EN 45544-3) or commercial premises, for CO measurement for smoke and fire detection. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、dard include recreational craft, caravans and motor caravans NOTE Other motorised vehicles like trucks are known to have residential accommodation. They are not recreational vehicles but are considered as similar premises in respect of this European Standard. 3.2 recreational craft boat of a minimum
32、 length of 2,5 m and a maximum length of 24 m as specified in Directive 94/25/EC, which is intended for sports or leisure purposes NOTE For the purposes of this European Standard the word boat should be taken with the meaning recreational craft. 3.3 remote sensor sensor assembly that is mounted in a
33、 separate location from the control unit NOTE This definition should be read in conjunction with EN 50291-1, Definition 3.7. 3.4 control unit unit that may contain the power supply, signal processing, alarm circuits and indicators 3.5 vehicle supply powered apparatus apparatus designed to be powered

37、licable, with the following addition: In this European 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 with the requirements for recreational craft will
38、 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 operation. NOTE 1 When the vehicle is not in use t
39、he apparatus may be switched off in order to save the vehicles power supply or the internal batteries. The apparatus may consist of one or more sensor(s) and a control unit. Sensors (integrated into the apparatus or remote) shall be designed to detect carbon monoxide. NOTE 2 Sensors or apparatus des
40、igned according EN 50291-1 may be used as apparatus or as component of it, if the additional requirements of this European Standard are complied with. The apparatus shall reliably detect the presence of carbon monoxide in recreational vehicles under the stated application conditions, shall produce a
41、n alarm and Type A apparatus shall be able to initiate executive actions whenever the level exceeds the alarm set point. The apparatus, electrical assemblies and components shall comply with EN 50291-1, where applicable, with the construction requirements of 4.2 to 4.7 and the test and performance r
42、equirements of Clause 5. 4.2 Construction This subclause of EN 50291-1 is applicable, with the following addition: Each sensor shall be constructed of materials that will not corrode in the environment where it is designed for, e.g. in the presence of a salt-laden atmosphere as exists in a marine en
43、vironment, or be affected by the gases and vapours that may be expected to be present in a recreational craft. Adequate means shall be provided to mount the remote sensor(s), pointing vertically downwards, securely to the vehicles substructure. The control unit shall be constructed of materials that
44、 are suitable for use in the intended application e.g. in the cabin or below deck area of a recreational craft. 4.3 Indicators and alarms This subclause of EN 50291-1 is applicable, with the following addition: 4.3.3 Addition: If more than one sensor is connected to a control unit, the control unit
45、shall indicate the alarm condition of the different sensors individually.
