Emergency lighting equipment

Preface

This is the sixth edition of CSA C22.2 No. 141, Emergency lighting 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 2015, 2010, 2002, 1985, and 1972. The following are the major changes to this edition

  1. clarification for battery performance during operating conditions (see Clause 4.3.3)
  2. clarification for the operation of equipment at extreme temperatures (see Clauses 4.3.4, 7.6.2, 7.12.1, and 7.12.2)
  3. clarification of the type of switch used for the testing of operation of equipment with batteries (see Clause 4.5)
  4. revision to the references for maximum permitted dimensions of openings in enclosures (see Clauses 5.2.3 and 5.2.5)
  5. additional note for the minimum life of LED lamps (see Clause 5.19)
  6. revision to the equipment input marking (see Clause 6.1)
  7. replacing the annex for energy efficiency with a direct reference to CAN/CSA-C860 (see Clauses 6.14 and 7.20)
  8. addition of new requirements for marking equipment that does not meet the requirements of ICES-005 (see Clause 6.19 and Annex D)
  9. additional clarification for the particular tests required for equipment not provided with batteries and sample requirements for all tests (see Clause 7.1)
  10. clarifications and editorial corrections for the conditions for test and preparation of unit equipment (see Clauses 7.2 and 7.3)
  11. clarifications for conducting the rating (input) test and temperature test (see Clauses 7.4 and 7.6)
  12. moving the charging means test (see Clause 7.5)
  13. addition of requirements for determination of equivalent temperatures during the temperature test (see Clause 7.6.5)
  14. addition of a new over-voltage test (see Clause 7.7)
  15. clarification and simplification of the leakage current test (see Clause 7.8)
  16. addition of an exclusion of equipment that must comply with the dielectric test, dielectric test equipment requirements, and additional requirements for units using voltage-limiting clamping devices (see Clause 7.9)
  17. clarification for equipment evaluated for short-term recovery (see Clause 7.10)
  18. correction for the test reference for flooded cell batteries (see Clause 7.11)
  19. clarification for equipment evaluated for minimum ambient temperature (see Clause 7.12)
  20. clarification for equipment evaluated for minimum extreme voltage (see Clause 7.13)
  21. separating central power system testing from the minimum extreme voltage test (see Clause 7.24)
  22. revision to the notes of Figure B.1 for the direction of a directional indicator
  23. addition of new requirements to address lamp conditioning and the maximum test voltage for a remotely operated luminaire during the light output test (see Annex C)
  24. clarification for diffuser flammability requirements (see Annex E)
  25. and revision to reference the maximum and minimum voltage levels in the normal and extreme operating range from CSA C235 (see Clauses 4.3.3.1, 4.3.3.2, 5.2.1.6, 7.4.3, 7.7, 7.13.1, and 7.14.2).

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Subcommittee on Lighting Products (ICLP), under the jurisdiction of the Technical Committee on Consumer and Commercial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and was formally approved by the Technical Committee. This 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
1.1 Classification

This Standard applies to exit signs, unit equipment, emergency luminaires, and central power systems intended for connection to circuits with nominal voltages of 600 V and less, and providing illumination in the event of a failure of the normal power supply for non-hazardous locations in accordance with the Canadian Electrical Code, Part I.

1.2 Application

This Standard includes requirements for the construction of emergency lighting equipment to preclude fire and shock hazards, and to ensure the equipment has the minimum capability for performing its intended function.

1.3 Terminology

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.

1.4 Dual measurements

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
