Introduction
This document 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 and rooms with similar
purposes. 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 the
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 smoke alarms.

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).
8
---------------------- Page: 10 ----------------------
SIST EN 50292:2023
EN 50292:2023 (E)
4.2 Normal exposure levels
Carbon monoxide can be generated within a building or enter from outside. Typically 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, petrol and ethanol) and gaseous fuels (such
as natural gas, town gas and liquefied petroleum gas (LPG)).
It should be noted that town gas might still be in use in some 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. In addition, poorly maintained
and inefficient burners can produce considerably higher levels of carbon monoxide.
Another topic of concern is flue reversal. A flue reversal may occur both under certain climatic conditions (e.g.
inversion weather situations), as well as in the cases of foreign bodies completely or partially blocking the smoke
fumes. This applies to facilities where the combustion air is taken from the rooms, as well as to those whose
combustion air is supplied to the appliance independent from room air. This is normally a temporary
phenomenon. But it cannot be foreseen, and it may occur at any time, and it may last over an incalculable period
of time, even if the appliance is 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 (Liquid Petroleum Gas) 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.
Portable cooking and heating equipment: it should be emphasized that charcoal grills emit very high levels of
carbon monoxide and should only be used outdoors, but never as an air heater in any kind of recreational
facilities, including tents.
It is also warned about the indoor operation of gas-powered mobile heaters (mushroom / patio heaters). Even
those devices can emit increased levels of carbon monoxide and should therefore be operated only outdoors.
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.
9
---------------------- Page: 11 ----------------------
SIST EN 50292:2023
EN 50292:2023 (E)
4.5 Tobacco smoking
Smoking produces a significant concentration of carbon monoxide. This becomes a particular problem in
situations where there are large number of smoke emitting sources such as shisha venues. Unfortunately, in
this particular case it is difficult to recommend the use of EN 50291-1 alarms and advise on siting due to the
fact that the sources of CO are regularly relocated.
4.6 Fuel burning appliances
The products of combustion for any fuel burning appliance are particularly dangerous in enclosed spaces. This
would include exhaust gases from internal combustion engines and large heating systems in residential boiler
rooms.
The exhaust gases from internal combustion engines (vehicles or electricity generators for example) running in
an enclosed space can quickly produce dangerous levels of carbon monoxide.
4.7 Migration of CO
Latest studies have shown that released CO (i.e. in a boiler room) can spread not only by diffusion through open
spaces such as cable ducts, door sills, keyholes, etc., but also by permeation through walls and ceilings
throughout the entire building. The speed of permeation depends on the building materials used (wood, brick,
concrete, plasterboard, etc.) and cannot generally be given as an exact value. For this reason, it is
recommended that as a minimum, every room with a fuel burning appliance should be equipped with an
apparatus to detect any notable exposition of CO as early as possible.
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 Planning and configuration
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. To minimize the risk of nuisance alarms or damage to the sensors, in the
following sections only general guidance can be given as to where apparatus should be installed or which
mounting locations are unsuitable for this purpose.
5.2.2 Configuration and installation
5.2.2.1 Rooms
An apparatus should be installed in every room containing a fuel-burning appliance.
a) If a fuel-burning appliance is in a room that is part of the dwelling, the apparatus may be interconnected to
other apparatus or smoke alarms according to the requirements of EN 50291-1:2018, 5.13, within the same
dwelling, to ensure an appropriate early warning for occupants:
— in rooms in which the occupant(s) spend considerable time whilst awake and from which they may not
be able to hear an alarm from apparatus in another part of the premises, i.e. due to a complex and/ or
large dwelling or closed doors between the apparatus and other rooms;
— in every sleeping room.
10
---------------------- Page: 12 ----------------------
SIST EN 50292:2023
EN 50292:2023 (E)
b) If a dwelling is 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.
c) If a fuel-burning appliance is in a room which is not normally frequented (for example a boiler room), the
apparatus should be interconnected to e.g. smoke alarms or to ancillary devices (siren, beacon) in other
rooms and/ or circular spaces to ensure an appropriate early warning is given for occupants elsewhere in
the building. If CO is detected, it is recommended that those interconnected devices operate with a sound
pattern that is different from i.e. a smoke or fire alarm.
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.

Introduction
This document 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 smoke alarms.

1 Scope
This document 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 is read
in conjunction with EN 50291-1 and EN 50291-2 together with any additional relevant national or local
regulations.
This document 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 document 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 a building 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, petrol and ethanol) 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. In addition, poorly
maintained and inefficient burners can produce considerably higher levels of carbon monoxide.
A flue reversal may occur both under certain climatic conditions (e.g. inversion weather situations), as well as
in the cases of foreign bodies completely or partially blocking the smoke fumes. This applies to facilities where
the combustion air is taken from the rooms, as well as to those whose combustion air is supplied to the
appliance independent from room air. This is normally a temporary phenomenon. But it cannot be foreseen,
and it may occur at any time, and it may last over an incalculable period of time, even if the appliance is
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 (Liquid Petroleum Gas) 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.
Portable cooking and heating equipment. It should be emphasized that charcoal grills emit very high levels of
carbon monoxide and should only be used outdoors, but never as an air heater in any kind of recreational
facilities, including tents.
10
---------------------- Page: 12 ----------------------
oSIST prEN 50292:2022
prEN 50292:2022 (E)
It is also warned about the indoor operation of gas-powered mobile heaters (mushroom / patio heaters). Even
those devices can emit increased levels of carbon monoxide and should therefore be operated only outdoors
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. This becomes a particular problem in
situations where there are large number of smoke emitting sources such as shisha venues. Unfortunately, in
this particular case it is difficult to recommend the use of EN 50291-1 alarms and advise on siting due to the
fact that the sources of CO are regularly relocated.
4.6 Fuel burning appliances
The products of combustion for any fuel burning appliance are particularly dangerous in enclosed spaces.
This would include exhaust gases from internal combustion engines and large heating systems in residential
boiler rooms.
The exhaust gases from internal combustion engines (vehicles or electricity generators for example) running
in an enclosed space can quickly produce dangerous levels of carbon monoxide.
4.7 Migration of CO
Latest studies have shown that released CO (i.e. in a boiler room) can spread not only by diffusion through
open spaces such as cable ducts, door sills, keyholes, etc., but also by permeation through walls and ceilings
throughout the entire building. The speed of permeation depends on the building materials used (wood, brick,
concrete, plasterboard, etc.) and cannot generally be given as an exact value. For this reason, it is
recommended that every room with a fuel burning appliance should be equipped with an apparatus to detect
any notable exposition of CO as early as possible.
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 Planning and Configuration
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. To minimize the risk of nuisance alarms or damage to the sensors, in the
following sections only general guidance can be given as to where apparatus should be installed or which
mounting locations are unsuitable for this purpose.

5.2.2 Configuration and installation
5.2.2.1 Rooms
An apparatus should be installed in every room containing a fuel-burning appliance.
a) If a fuel-burning appliance is in a room that is part of the dwelling, the apparatus may be interconnected
to other apparatus or smoke alarms according to the requirements of EN 50291-1:2018, 5.13, within the
same dwelling, to ensure an appropriate early warning for occupants
— in rooms in which the occupant(s) spend considerable time whilst awake and from which they may
not be able to hear an alarm from apparatus in another part of the premises, i.e. due to a complex
and/ or large dwelling or closed doors between the apparatus and other rooms
— in every sleeping room.
