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).
