BS EN 54-26:2015EN 54-26:2015 (E) 7 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 becaus

38、e 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 monoxid

39、e (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. overheat

40、ing 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

41、 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 oth

42、er 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 rat

43、her 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 evaluat

44、ing CO fire detectors. BS EN 54-26:2015EN 54-26:2015 (E) 8 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

45、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 differen

46、t 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 fu

47、nctionality for which this standard does not define a test or assessment method). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
