BS EN 50131-2-7-1:2012+A1:2013 corrigendum August 2014 BS Incorporating EN 50131-2-7-1:2012 BSI Standards Publication Alarm systems — Intrusion and hold-up systems Part 2-7-1: Intrusion detectors — Glass break detectors (acoustic) BS EN 50131-2-7-1:2012+A1:2013 BRITISH STANDARD National foreword This British Standard is the UK implementation of EN 50131-2-7-1:2012+A1:2013 It supersedes BS EN 50131-2-7-1:2012, which is withdrawn The start and finish of text introduced or altered by amendment is indicated in the text by tags Tags indicating changes to CENELEC text carry the number of the CENELEC amendment For example, text altered by CENELEC amendment A1 is indicated by  The UK participation in its preparation was entrusted by Technical Committee GW/1, Electronic security systems, to Subcommittee GW/1/1, Alarm components A list of organizations represented on this subcommittee can be obtained on request to its secretary This publication does not purport to include all the necessary provisions of a contract Users are responsible for its correct application © The British Standards Institution 2014 Published by BSI Standards Limited 2014 ISBN 978 580 83561 ICS 13.320 Compliance with a British Standard cannot confer immunity from legal obligations This British Standard was published under the authority of the Standards Policy and Strategy Committee on 31 October 2013 Amendments/corrigenda issued since publication Date Text affected 31 August 2014 Implementation of CENELEC Interpretation Sheet February 2014 in National Annex NA 31 August 2014 Implementation of CENELEC amendment A1:2013 BS EN 50131-2-7-1:2012+A1:2013 EN 50131-2-7-1:2012/IS1:2014 (E) National Annex NA (Informative) Text of IS1 to EN 50131-2-7-1:2012 Clause: Annex D and Figure D.1 Question: Would it be allowed for test purposes (for test houses and manufacturers) to use the NeoDym magnet listed below instead of the AlNiCo version described in Annex D and Figure D.1 for reproducible tests ? Interpretation: Yes, because this will allow stable and reproducible test results, which is not guaranteed while using the AlNiCo magnet due to the nature of the magnet material Furthermore, the test magnet described below allows a high-level degree of backward compatibility for already tested products, while it gives the stability required Therefore, when the NeoDym magnet is used for test purposes (for test houses and manufacturers), the text below may be used in place of Annex D Validity: This interpretation remains valid until an amendment or updated standard dealing with this issue is published by CENELEC EN 50131-2-7-1:2012/IS1:2014 (E) BS EN 50131-2-7-1:2012+A1:2013 Annex D (normative) Dimensions & requirements of a standard test magnet D.1 Normative references The interference test magnets shall comprise a magnet identical to the corresponding magnet supplied with the detector and one of the following specified independent test magnets according to whether the detector is surface or flush mounted The following standards will form the base for the selection of the independent test magnet: EN 60404-5, Magnetic materials – Part 5: Permanent magnet (magnetically hard) materials – Methods of measurement of magnetic properties (IEC 60404-5) EN 60404-14, Magnetic materials – Part 14: Methods of measurement of the magnetic dipole moment of a ferromagnetic material specimen by the withdrawal or rotation method (IEC 60404-14) IEC 60404-8-1, Magnetic materials – Part 8-1: Specifications for individual materials – Magnetically hard materials D.2 Requirements The field strength of the magnet determined by the magnetic material, by remanence (Br) in mT and the product of energy (BH)max in kJ/m³, which are material dependent as the values describe the full saturation of that material should be measured before any calibration took place The field strength of the test magnet needs to be adjusted at the polarization of the working point in mT as defined The relevant value, dimensions and measurement point for the test magnet can be found in the following drawings and tables For calculations, measurements and calibration of the test magnets, the norms cited above shall be used The independent test magnet for Test Magnet Type is described in Figure D.1 To get the magnets in question adjusted to the proper values and calibrated (e.g polarization in working point), it is strongly suggested to perform adjustments of the magnetic values for ordered magnets performed by an accredited test house for magnetic fields One potential source could be the following: MAGNET-PHYSIK Dr Steingroever GmbH Emil-Hoffmann-Strasse 50966 Cologne, Germany www.magnet-physik.de EN 50131-2-7-1:2012/IS1:2014 (E) BS EN 50131-2-7-1:2012+A1:2013 Key North pole South pole North pole Material NdFeB N40 (REFeB 310/130 -
