Fire detection and fire alarm systems - Part 26: Carbon monoxide detectors - Point detectors
This European Standard specifies requirements, test methods and performance criteria for point detectors using carbon monoxide sensing for use in fire detection and fire alarm systems in and around buildings (see EN 54 1:2011).
This European Standard provides for the assessment and verification of consistency of performance (AVCP) of carbon monoxide point detectors to this EN.
This European Standard does not cover fire detectors incorporating at least one CO sensing element in combination with other elements sensing different fire phenomena.
CO detectors having special characteristics suitable for the detection of specific fire risks are not covered by this European Standard. The performance requirements for any additional functions are beyond the scope of this European Standard (e.g. additional features or enhanced functionality for which this standard does not define a test or assessment method).

Introduction
Carbon monoxide (CO) is a product of the incomplete combustion of carbon-based materials. CO fire
detectors can react promptly to smouldering fires involving carbonaceous materials because CO does not
depend solely on convection, but also moves by diffusion. CO fire detectors might be better suited to
applications where other fire detection techniques are prone to false alarms, i.e. due to dust, steam and
cooking vapours.
The purpose of this standard is to ensure that carbon monoxide (CO) fire detectors have adequate sensitivity
and reliability for use in fire detection and fire alarm systems for residential commercial and industrial
premises. CO may not be produced in detectable quantities where pyrolysis of material rather than self-
sustained combustion occurs (e.g. overheating cables) or in the early stages of rapidly burning flaming fires
(e.g. liquid fuel fires). It is important that carbon monoxide fire detectors are only used where a risk
assessment indicates that they are appropriate for detecting the types of fires that may occur. CO fire
detectors should not be considered as a direct replacement for smoke detectors. CO fire detectors detect
carbon monoxide gas rather than the smoke particulates detected by optical and ionization smoke detectors.
A number of different methods for sensing CO are suitable. However, most sensors will also be influenced by
other gases and phenomena. Tests have therefore been included in the test schedule to assess cross-
sensitivity to substances normally present in the service environment that may affect the performance of the
detector.
As CO detectors are specifically well suited for the detection of incipient fires rather than flaming fires this
standard only includes tests to verify performance in smouldering fires. For this purpose, test fires TF2 and
TF3 from EN 54-7 have been included in the test schedule. An additional validity criterion has been added to
each of these tests to make them suitable for evaluating CO fire detectors.

1 Scope
This European Standard specifies requirements, test methods and performance criteria for point detectors
using carbon monoxide sensing for use in fire detection and fire alarm systems in and around buildings
(see EN 54-1:2011).
This European Standard provides for the assessment and verification of consistency of performance (AVCP)
of carbon monoxide point detectors to this EN.
This European Standard does not apply to fire detectors incorporating at least one CO sensing element in
combination with other elements sensing different fire phenomena.
CO detectors having special characteristics suitable for the detection of specific fire risks are not covered by
this European Standard. The performance requirements for any additional functions are beyond the scope of
this European Standard (e.g. additional features or enhanced functionality for which this standard does not
define a test or assessment method).
