Electrical apparatus for the detection of carbon monoxide in domestic premises, caravans and boats - Guide on the selection, installation, use and maintenance
This European Standard serves as a guide on the selection, installation, use and maintenance of apparatus for the detection of carbon monoxide, intended for continuous operation in a fixed installation in domestic premises, caravans and boats. This guide is intended to cover any type of domestic or residential accommodation, including leisure accommodation vehicles such as touring and static caravans, and motor homes; and recreational craft such as canal barges. Some static caravans are used as permanent dwellings, in such cases EN 50291-1 is appropriate. For all other types of caravan, EN 50291-2 is appropriate. This guide should be read in conjunction with EN 50291-1 and EN 50291-2 together with any additional relevant national or local regulations. This European Standard refers to the installation of two types of apparatus: a) Type A apparatus, to provide a visual and audible alarm and an executive action in the form of an output signal that can be used to actuate directly or indirectly a ventilation or other ancillary device; b) Type B apparatus, to provide a visual and audible alarm only. This European Standard excludes apparatus for the detection of combustible gases (see EN 50244) and for industrial installations or commercial premises.

Foreword
This document (EN 50292:2013) has been prepared by CLC/TC 216, "Gas detectors".
The following dates are fixed:
• latest date by which this document has to be implemented at (dop) 2014-07-15
national level by publication of an identical national standard or
by endorsement
• latest date by which the national standards conflicting with this (dow) 2016-07-15
document have to be withdrawn
This document supersedes EN 50292:2001.
minor changes have also been made).
– Title and definitions are revised to be more general, i.e. to cover domestic premises, boats and caravans.
This is a result of the splitting of EN 50291 into EN 50291-1 and EN 50291-2.
– In 4.3.1 of EN 50292:2001, incorrect terminology "warm air systems" is replaced by "ducted air heaters" (in
4.3.2 of EN 50292:2013).
– In 4.7, a more general title replaces the previous one as CO migration applies not only to multi-occupancy
and multi-storey buildings but also to any premises connected to other premises, such as semi-detached
and terrace premises, where the migration of CO is possible.
– In 5.2.1 and 5.2.2, the use of caravans and boats is included in installation/location information.
– In 5.3, an additional type of apparatus is added, capable of identifying lower concentrations of CO than
would be needed to trigger an alarm. Such features are available in certain products, and may be useful to
some at-risk groups, especially people who have respiratory health issues.
– In 6.2, the text is modified so that triggering a shut-off valve should be on the main gas supply, ideally at
the gas meter/cylinder outlet, so that the entire installation is isolated (and not only individual appliances as
stated in the previous version), as the source may not be that appliance.
– In 6.4, the text is modified to state that it is more important that the gas supply is isolated rather than the
electrical supply. There is no need to make an exception for a gas appliance with an electrical connection.
The carbon monoxide detection apparatus should not be used to operate the mains electrical switch, since
such action may create unnecessary hazard for occupants of the premises.
– A new subclause 7.1 "Use of alarm" is added. It includes the requirement to advise the user that a CO
alarm does not replace the correct installation, commissioning and regular maintenance by a competent
person. This is required in the instruction booklet by EN 50291-1:2010, 4.7.4, item 'n'.
NOTE This was already stated in the introduction to EN 50292 but it is emphasised in the new 7.1.
– In 7.5, text relating to hydrogen interference is added.
– In Clause 8, recommendation to isolate the emergency control valve for gas installations is added.
– In Clause 8, text advising that the Gas Emergency Service Provider should be contacted in the first
instance is added.
– A new Figure A.1 is added, showing CO-concentration and exposure time curves for various COHb levels
including 2,5 % COHb (the protection level recommended by WHO).
– In A.2, text about health effects on vulnerable groups, derived from WHO, is added.
– Figure B.1 is modified to illustrate how alarm set points in EN 50291-1 align with the 2,5 % and 5 % COHb
curves, providing a more practical rationale rather than the previous theoretical one.
Introduction
This European Standard is intended to be a guide for people who, in the course of their professional activities,
are required to install apparatus for the detection of carbon monoxide (CO) in domestic premises. It is also
aimed at anyone who might supply such detectors to members of the public for subsequent installation
according to national regulations, so that advice may be given based on good engineering practice.
Apparatus for the detection of carbon monoxide are not a substitute for good installation and regular servicing
of fuel burning appliances or regular cleaning of chimneys, although they may provide an added margin of
reassurance for users. Domestic carbon monoxide detectors with or without some form of executive function
may overcome fears of fuel safety and may be particularly beneficial in certain circumstances.
It is necessary to understand that carbon monoxide toxicity may have different consequences according to the
physical condition of the individual. Thus, a carbon monoxide detector designed according to EN 50291 series
may not fully safeguard individuals with specific medical conditions.
Carbon monoxide detectors are not intended to be used as an alternative to a smoke alarm.

1 Scope
This European Standard serves as a guide on the selection, installation, use and maintenance of apparatus for
the detection of carbon monoxide, intended for continuous operation in a fixed installation in domestic
premises, caravans and boats. This guide is intended to cover any type of domestic or residential
accommodation, including leisure accommodation vehicles such as touring and static caravans, and motor
homes; and recreational craft such as canal barges. Some static caravans are used as permanent dwellings,
in such cases EN 50291-1 is appropriate. For all other types of caravan, EN 50291-2 is appropriate. This guide
should be read in conjunction with EN 50291-1 and EN 50291-2 together with any additional relevant national
or local regulations.
This European Standard refers to the installation of two types of apparatus:
a) Type A apparatus, to provide a visual and audible alarm and an executive action in the form of an output
signal that can be used to actuate directly or indirectly a ventilation or other ancillary device;
b) Type B apparatus, to provide a visual and audible alarm only.
This European Standard excludes apparatus for the detection of combustible gases (see EN 50244) and for
industrial installations or commercial premises.

4 Sources of carbon monoxide
4.1 General information
Carbon monoxide is a colourless, odourless, non-irritating gas which is classified as a chemical asphyxiant,
whose toxic action is a direct result of the hypoxia produced by a given exposure (see Annex A and Annex B).
4.2 Normal exposure levels
Carbon monoxide can be generated within the home or enter from outside. The normal average background
levels of carbon monoxide in domestic premises, measured over periods of 1 h to 24 h, are less than 10 ppm.
In cases of climatic inversion, higher levels of carbon monoxide are possible.
4.3 Burning of carbonaceous materials for heating and cooking
4.3.1 General
Most of the carbon monoxide in the environment is produced during combustion of carbonaceous material,
e.g. solid fuels (such as coal, coke and wood), liquid fuels (such as oil and petrol) and gaseous fuels (such as
natural gas, town gas and liquefied petroleum gas (LPG)).
It should be noted that town gas is still used in some EU countries and it can contain a significant proportion of
carbon monoxide prior to combustion.
The proportion and constituents of the combustion products from carbonaceous fuels will depend on the
particular fuel and the combustion conditions.
Varying concentrations of carbon monoxide are produced from most combustion processes. Exhaust gases
from burning solid and liquid fuels may contain significant concentrations of carbon monoxide: levels of
20 000 ppm to 50 000 ppm (2 % to 5 %) are not unexpected. For example, burning coal, wood or peat can
produce concentrations of 20 000 ppm, 40 000 ppm and 50 000 ppm respectively. Efficient burning of natural
gas and LPG in well-designed burners in an excess of air will not produce significant flue concentrations of
carbon monoxide, usually in the range 10 ppm to 200 ppm. However, poorly maintained and inefficient burners
can produce considerably higher levels of carbon monoxide.
Flue reversal may occur under certain climatic conditions with appliances using combustion air taken from
within the premises. This is normally a temporary phenomenon that may occur with certain types of appliance,
even when correctly maintained.
4.3.2 Space and water heating
Solid, liquid and gaseous fuels may be used for space and water heating. They are used in a variety of ways,
either as a local heat source or as a remote central heat source, including
– appliance with flue using room air,
– appliance without flue using room air,
– appliance with flue using external air.
In the case of a defective ducted air heater, carbon monoxide can be distributed into remote rooms.
4.3.3 Cooking
Natural gas, town gas or LPG are the main fuels for cooking, typically using flueless appliances including
cooking ranges. In some cases, solid fuels or oil are used in cooking appliances that are generally fitted with
flues.
It should be emphasised that barbecue grills using charcoal, emit very high amounts of carbon monoxide and
should only be used outdoors and should not be used as air heaters in any leisure accommodation, including
tents.
4.4 Uncontrolled burning
Carbon monoxide is a major gaseous product from fires resulting from uncontrolled burning of carbonaceous
material. Varying concentrations of carbon monoxide are produced, depending on the material, burning
conditions, etc.
4.5 Tobacco smoking
Smoking produces a significant concentration of carbon monoxide.
4.6 Internal combustion engines
A major source of carbon monoxide in the non-industrial environment is the combustion engine. The
concentration of carbon monoxide in exhaust gas is normally in the range 1 % to 3 %
(10 000 ppm to 30 000 ppm) but may reach 7 % (70 000 ppm) in a badly maintained or badly tuned engine.
The exhaust gases from internal combustion engines (vehicles or electricity generators for example) running in
an enclosed space will quickly produce dangerous levels of carbon monoxide.
4.7 Migration of CO
Carbon monoxide produced in one area within an individual dwelling or in connected premises such as semi-
detached and terraced premises, maisonettes, and particularly multi-occupancy and multi-storey buildings, can
be transported to and leak into another part of the building, e.g. across roof spaces, between floors, along
ducting, in shared flues, chimneys and other re-entry points such as air vents.
5 Installation
5.1 General
The manufacturer is required to provide suitable instructions for the correct and safe installation of the
apparatus and to indicate on the apparatus and its packaging that these instructions should be read carefully
before installing or operating the apparatus.
Generally, the same considerations apply to both type A and type B apparatus.
5.2 Location of the apparatus
5.2.1 General
The design and layout of domestic premises, caravans and boats and the number, type and position of carbon
monoxide sources vary widely. General guidance is given in the following clauses on where and where not to
locate the apparatus in order to minimise the risk of misleading indications.
- 9 - EN 50292:2013
5.2.2 Which room?
5.2.2.1 General
Ideally, an apparatus should be installed in every room containing a fuel-burning appliance and additional
apparatus should be installed to ensure that adequate warning is given for occupants in other rooms, by
locating apparatus
– in remote rooms in which the occupant(s) spend considerable time whilst awake and from which they may
not be able hear an alarm from apparatus in another part of the premises, and
– in every sleeping room.
If there is a fuel-burning appliance in more than one room and the number of apparatus is limited, the following
points should be considered when deciding where best to position the apparatus:
a) locate the apparatus in a room containing a flueless or open-flued appliance, and
b) locate apparatus in a room where the occupant(s) spend most time.
If the domestic premises are a bedsit (a single room serving as both sitting and bedroom), then the apparatus
should be positioned as far from the cooking appliances as possible but near to where the person sleeps.
If the appliance is in a room not normally frequented (for example a boiler room), the apparatus should be
positioned so that the alarm may be heard more easily. Alternatively, an interlinked apparatus or a remote
alarm siren may be connected to a type A apparatus located in a room(s) containing a fuel-burning appliance.
Where a fuel-burning appliance has an extended and/or concealed flue, an apparatus should be installed in
each room through which the flue passes.
5.2.2.2 Caravans and boats
Caravans and boats may have additional risks of carbon monoxide ingress
