27、 71 BS EN 54-12:2015EN 54-12:2015 (E) 5 Foreword This document (EN 54-12:2015) 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 publi

28、cation of an identical text or by endorsement, at the latest by October 2015, and conflicting national standards shall be withdrawn at the latest by April 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC sh

29、all not be held responsible for identifying any or all such patent rights. This document supersedes EN 54-12:2002. 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 Regulation (EU) 3

30、05/2011. For relationship with EU Regulations see informative Annex ZA, which is an integral part of this document. EN 54-12 has been revised so as to align with the second answer to Mandate M/109. It includes new clauses and annexes as follows: Clause 6 Assessment and verification of constancy of p

31、erformance (AVCP); Clause 7 Classification and designation; Clause 8 Marking, labelling and packaging; Annex H (informative) Information concerning the requirements for the response to slowly developing fires; Annex I (informative) Data supplied with line detectors using an optical beam. The main te

32、chnical changes are as follows: The definition of response value has been modified so that it relates the same smoke density for line detectors using an optical beam both with and without a separate reflector. Changes to the test conditions and requirements for the Tolerance to beam misalignment tes

33、t and the Vibration (endurance) test.

BS EN 54-12:2015EN 54-12:2015 (E) 7 1 Scope This European Standard specifies requirements, test methods and performance criteria for line detectors using an optical beam that detect smoke by utilizi

42、ng the attenuation and/or changes in attenuation of an optical beam, for use in fire detection and fire alarm systems installed in buildings (see EN 54-1:2011). This European Standard provides for the assessment and verification of constancy of performance (AVCP) of line detectors using an optical b

43、eam to this EN. This European Standard does not cover: line detectors using an optical beam designed to operate with separations between opposed components of less than 1 m; line detectors using an optical beam whose optical path length is defined or adjusted by an integral mechanical connection; li

44、ne detectors using an optical beam with special characteristics, which cannot be assessed 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

45、restricted to visible wavelengths. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
