5.1 General requirements
This sub-clause of EN 50291-1 is applicable, 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 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 the apparatus may be switched off in order to save the vehicle’s 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 designed 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 an 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 5.2 and the test and performance requirements of Clause 6.
5.2 Construction
This sub-clause 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 environment, 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
vehicle’s 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 recreational craft.
5.4 Alarms
This sub-clause of EN 50291-1 is applicable, with the following addition:
5.4.4 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.

100 NOTE 2 Sensors or apparatus designed according EN 50291-1 may be used as apparatus or as component of it, if the
101 additional requirements of this European Standard are complied with.
102 The apparatus shall reliably detect the presence of carbon monoxide in recreational vehicles under the stated
103 application conditions, shall produce an alarm and Type A apparatus shall be able to initiate executive actions
104 whenever the level exceeds the alarm set point.
105 The apparatus, electrical assemblies and components shall comply with EN 50291-1, where applicable, with the
106 construction requirements of 5.2 and the test and performance requirements of Clause 6.
107 5.2 Construction
108 This sub-clause of EN 50291-1 is applicable, with the following addition:
109 Each sensor shall be constructed of materials that will not corrode in the environment where it is designed for, e.g.
110 in the presence of a salt-laden atmosphere as exists in a marine environment, or be affected by the gases and
111 vapours that may be expected to be present in a recreational craft.
112 Adequate means shall be provided to mount the remote sensor(s), pointing vertically downwards, securely to the
113 vehicle’s substructure.
114 The control unit shall be constructed of materials that are suitable for use in the intended application e.g. in the
115 cabin or below deck area of a recreational craft.
116 5.4 Alarms
117 This sub-clause of EN 50291-1 is applicable, with the following addition:
118 5.4.4 Addition:

120 different sensors individually.
121 5.6 Fault Warnings
122 This sub-clause of EN 50291-1 is replaced by:
123 The apparatus shall provide a visual and audible fault signal in the event of interruption of communication between
124 control unit and the remote sensor(s).
125 The audible fault signal shall be clearly identified and different from a gas alarm.
126 5.9 Transmittable output signal (applicable for type A apparatus only)
127 This sub-clause of EN 50291-1 is applicable, with the following addition:
