26、nt EN 54-12:2002 has been prepared by Technical Committee CEN/TC 72 “Fire detection and fire alarm systems”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest b
27、y May 2003, and conflicting national standards shall be withdrawn at the latest by November 2005. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship
28、with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This standard has been prepared in cooperation with the CEA (Comit Europen des Assurances) and with EURALARM (Association of European Manufacturers of Fire and Intruder Alarm Systems). Information on the rela
29、tionship between this European Standard and other standards of the EN 54 series is given in annex A of EN 54-1:1996. In this European Standard the annexes A to G are normative.

31、. c o m EN 54-12:2002 (E) 6 1 Scope This European Standard specifies requirements, test methods and performance criteria for line smoke detectors utilising the attenuation and/or changes in attenuation of an optical beam, for use in fire detection systems installed in buildings. This European Standa
32、rd does not cover: Line smoke detectors designed to operate with separations between opposed components of less than 1 m; Line smoke detectors whose optical path length is defined or adjusted by an integral mechanical connection; Line smoke detectors with special characteristics, which cannot be ass
33、essed by the test methods in this European Standard. NOTE The term “optical“ is used to describe that part of the electromagnetic spectrum produced by the transmitter to which the receiver is responsive; this is not restricted to visible wavelengths. 2 Normative references This European Standard inc
34、orporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this E
