35、over 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 automatically comply with the requirements for motor caravans and caravans. An apparatus whi
36、ch 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 the apparatus may be switched off in order to save the vehicles power supply or the internal b
37、atteries. 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 designed according EN 50291-1 may be used as apparatus or as component of it, if the additional
38、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 an alarm and Type A apparatus shall be able to initiate executive actions whenever the level e
39、xceeds 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 requirements of Clause 5. 4.2 Construction This subclause of EN 50291-1 is applicable, with th
40、e 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 environment, or be affected by the gases and vapours that may be expected to be present in a re
41、creational 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 are suitable for use in the intended application e.g. in the cabin or below deck area of a r
42、ecreational 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 shall indicate the alarm condition of the different sensors individually.

The audible fault signal shall be clearly identified and differe
44、nt from a gas alarm. 4.5 Output signal This subclause of EN 50291-1 is applicable, with the following addition: The output signal of the apparatus shall operate under the same conditions as the visual and audible alarm. For triggering an output signal, there shall be no built-in delay. 4.6 Software-
