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.
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. These have been modified to include monitoring
of the CO level during the test.
1 Scope
This European Standard specifies requirements, test methods and performance criteria for point fire detectors
using carbon monoxide sensing for use in fire detection and fire alarm systems for buildings (see EN 54-1).
This standard does not cover fire detectors incorporating at least one CO sensing element in combination with
other elements sensing different fire phenomena.
CO fire detectors with special characteristics and developed for specific risks are not covered by this standard.
