27、UL 1480 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the common UL and ULC Standard for Speakers for Fire Alarm and Signaling Systems, Including Accessories. It is the Fourth edition of CAN/ULC-S541 and Sixth edition of A
28、NSI/UL 1480. This Joint 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
29、 Alarm and Life Safety 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 fol
30、lowed by a value in 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 a
31、uthorities may require 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 Americ
32、an National Standard. Annexes A, C, and E are identied as informative and are for informational purposes only. Annexes B and D are identied as normative and form a mandatory part of this Standard. Note: Although the intended primary application of this Standard is stated in its scope, it is importan
33、t to note that it remains the 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 i
34、n technical content, except 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 justicat
35、ion, or the level of protection 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 comp
36、liance with the standard in 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 re
37、ect the intent.
