26、OT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the common UL and ULC Standard for Visible Signaling Devices for Fire Alarm and Signaling Systems, Including Accessories. It is the fourth edition of CAN/ULC-S526 and fth edition of ANSI/UL 1638. This J

27、oint Standard was prepared by Underwriters Laboratories Inc., ULC Standards, and the NEMA Technical Harmonization Committee on Notication Appliances. The standard was formally approved by the UL Standards Technical Panel on Signal Appliances and the ULC Technical Committee on Fire Alarm and Life Saf

28、ety Equipment and Systems. The efforts and support of the NEMA Technical Harmonization Committee, UL Standards Technical Panel, and ULC Technical Committee are gratefully acknowledged. Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in

29、 other units in parentheses, the second value may be approximate. The rst stated value is the requirement. In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possibility that some Canadian authorities may requ

30、ire additional markings and/or installation instructions to be in both official languages. This standard has been approved as a National Standard of Canada by the Standards Council of Canada. This standard has been approved by the American National Standards Institute as an American National Standar

31、d. Annexes A, B, and D are identied as informative and are for informational purposes only. Annex C is identied as normative and forms a mandatory part of this Standard. Note: Although the intended primary application of this Standard is stated in its scope, it is important to note that it remains t

32、he responsibility of the users of the standard to judge its suitability for their particular purpose. Level of Harmonization This Standard is published as an equivalent standard for UL and ULC Standards. An equivalent standard is a standard that is substantially the same in technical content, except

33、 as follows: Technical deviations are allowed for codes and governmental regulations and those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental, climatic, geographical, technological or infrastructural factors, scientic justication, or the level of protec

34、tion that the country considers appropriate. Presentation is to be word for word except for editorial changes. Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in

35、 accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent.
