前言:这是照明控制用非工业光电开关的统一NCE、CSA集团和UL标准。它是NMX-J-715-ANCE的第一版、CSA-C22.2第284-16号的第一版和UL 773A的第六版。本版UL 773A取代2006年2月10日发布的前一版。本协调标准于2020年6月26日共同修订。为此，CSA集团和UL于2020年6月26日发布修订页，ANCE于2020年6月26日发布新版。CSA集团标准还取代了本标准所涵盖产品的以下技术信息函（T.I.L.）:TIL编号A-15光电开关本标准是根据加拿大标准委员会对加拿大国家标准的要求制定的。 CSA集团已将其发布为加拿大国家标准。范围:1.1本标准中包含的要求涵盖光敏或存在敏感类型或两者的控制；用于室内或室外服务；用于控制最大20 a和最大347 V的室内或室外负载；适用于安装在50 Hz或60 Hz系统或高达60 V的直流电（美国）；直流电压高达42.4 V（适用于加拿大）；并按照国家电气规范（NEC）、NFPA 70、加拿大电气规范（CE规范）第一部分、CSA C22.2 No.0和NOM 001 SEDE安装。1.2这些要求不包括在以下条件下使用的控制装置:a）用于区域或道路照明灯具的锁定型装置； b） 监测或控制安全关键负载或个人保护电路的设备；c） 拟安装在指定危险位置的装置；d） 拟安装用于制造过程控制的设备。

Preface:This is the harmonized ANCE, CSA Group, and UL standard for Nonindustrial Photoelectric Switches for Lighting Control. It is the first edition of NMX-J-715-ANCE, the first edition of CSA-C22.2 No. 284-16, and the sixth edition of UL 773A. This edition of UL 773A supersedes the previous edition published on February 10, 2006. This harmonized standard has been jointly revised on June 26, 2020. For this purpose, CSA Group and UL are issuing revision pages dated June 26, 2020, and ANCE is issuing a new edition dated June 26, 2020.The CSA Group standard also replaces the following Technical Information Letters (T. I. L.), for products covered in this Standard:TIL No. A-15 Photo-electric switchesThis standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:1.1Requirements contained in this Standard cover controls of the light-sensitive or presence-sensitive types, or both; for indoor or outdoor service; intended for the control of indoor or outdoor loads up to a maximum of 20 A and maximum 347 V; intended for installations on 50 Hz or 60 HZ systems or DC up to 60 V (for US); and DC up to 42.4 V (for Canada); and intended to be installed in accordance with theNational Electrical Code(NEC), NFPA 70, theCanadian Electrical Code(CE Code) Part I, CSA C22.2 No. 0, and NOM 001 SEDE.1.2These requirements do not cover controls intended to be used under the following conditions:a) Devices that are locking type, used for area or roadway lighting fixtures;b) Devices that monitor or control safety critical loads or personal protection circuits;c) Devices intended to be installed in areas designated hazardous locations;d) Devices intended to be installed for manufacturing process control.
