détails du produit
This is the third edition of CSA C22.2 No. 205, Signal equipment, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 2012 and 1983.
This edition updates the 2012 edition of CSA C22.2 No. 205. The updates include the expanded scope to cover components that monitor and control activity and the equipment powered by an energy limited Class 2 power supply.
The updates are intended to provide clarification for many new signal applications that are now in use. This edition also incorporates the new requirements for ozone, toxic gas and radon detectors.
For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of the latest edition of CAN/CSA-C22.2 No. 0, General Requirements - Canadian Electrical Code, Part II.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard covers the electrical, fire, and shock hazard requirements for all permanently and cord- connected signal equipment intended for household, commercial and industrial use operating at
a) nominal system voltage of 120 V for household use;
b) nominal system voltages up to 600 V for commercial and industrial use; and
c) double insulated equipment up to 240 V.
in non-hazardous locations in accordance with the rules of the Canadian Electrical Code, Part I.
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 they specify the performance of signal equipment.
1) While this document does not address the performance aspects of signaling equipment it does specify requirements for the electrical safety of these devices, including functional safety.
2) Devices that generate radio frequency signals may also be subject to the requirements of Industry Canada.
This Standard covers equipment that performs a sensing and/or signaling function to convey alarm, trouble, status, or event-based information to the user and any subsequent associated activation function. The signal 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.
This Standard applies to energy management equipment including 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.
This Standard applies to components that monitor and control activity, and which are:
a) are inter-connected in a wireless sensor network (WSN) in a local network;
b) communicate with local devices that are either wired or wireless.
This Standard also applies to equipment powered by an energy limited Class 2 power supply.
Lighting photo relay systems, stand alone or incorporated within a luminaire, and evaluated as a combination in the final application are within the scope of this Standard.
This Standard does not apply to devices that are already covered by requirements of another Part II Standard.
Requirements for a specific type of equipment could have additional requirements as defined in Annexes A, B, D, and E.
Sensors used for medical applications for Class A, B, or C facilities (as defined in CSA Z32) are within the scope of the CAN/CSA-E60691 Series, and are not within the scope of this Standard.
Combustible gas detectors are evaluated to the requirements of CSA C22.2 No. 152 and carbon monoxide alarming devices for residential applications are evaluated to the requirements of CAN/CSA-6.19, and are outside the scope of this Standard.
Low level water cut-off is evaluated to the requirements of CSA C22.2 No. 24 and is outside the scope of this Standard.
Safety light curtains and similar products are outside the scope of this Standard.
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to 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 alternative 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-mandatory) to define their application.
