37、azardous locations in accordance with the rules of the Canadian Electrical Code, Part I.1.2 The requirements are not intended to replace other requirements that are mandated by provincial, federal, or authorities having jurisdiction for aspects other than electrical fire and shock hazards, nor do th
38、ey specify the performance of signal equipment.Notes: 1) While this document does not address the performance aspects of signaling equipment (volume of an audible indication or brightness of a visual indication), it does specify requirements for the electrical safety of these devices.2) Devices that
39、 generate radio frequency signals may also be subject to the requirements of Industry Canada.1.3 This Standard covers equipment that performs a sensing and/or signaling function to convey alarm, status, or event-based information to the user and any subsequent associated activation function. The sig
40、nal equipment may be stand alone or a part of a larger system. Signaling may employ wired or wireless means.Note: The equipment can employ audible, visual, motion, or other signaling means such as chimes, gongs, lights, and displays.1.4 This Standard applies to energy management equipment including
41、sensing, monitoring, and actuation devices. The requirements also apply to home automation systems. The signal sensing components meeting the requirement of this Standard can be included in a smart grid application for energy management, other than for industrial applications.1.5 Lighting photo rela
42、y systems, stand alone or incorporated within a luminaire, and evaluated as a combination in the final application are within the scope of this Standard.1.6 This Standard does not apply to devices that are already covered by requirements of another Part II Standard.C22.2 No. 205-12Signal equipmentNo

45、cut-off is evaluated to the requirements of CSA C22.2 No. 24 and is outside the scope of this Standard.1.11 Safety light curtains and similar products are outside the scope of this Standard.1.12 In CSA standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to
46、 satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.Notes accompanying clauses do not include requirements or alter
47、native requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.Notes to tables and figures are considered part of the table or figure and may be written as requirements.Annexes are designated normative (mandatory) or informative (non
48、mandatory) to define their application.2 Reference publicationsWhere reference is made to CSA Standards of the Canadian Electrical Code, Part II, such reference shall be considered to refer to the latest edition and revisions thereto, unless otherwise specified.This Standard refers to the following
