Wellington 6001 New Zealand ISBN 7262 9883 AS / NZS 2293.3:1995 PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee LG/7, Emergency Lighting in Buildings, to supersede, in part, AS 2293.1—1987* and, in part, NZS 6742:1971† This Standard sets out requirements for emergency luminaires and exit signs that form part of an emergency evacuation lighting system for a building The objective of these requirements is to ensure the safe and effective functioning of the emergency luminaires and exit signs under operational and environmental conditions representative of those which can reasonably be expected to apply in service Arising from a review of the 1987 edition of AS 2293.1, opportunity has been taken to collect together the requirements for emergency luminaires and exit signs to form a separate part (Part 3) of the AS/NZS 2293 series, leaving AS/NZS 2293.1‡ to cover requirements for the overall system design, installation and operation Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited The requirements in this Standard are essentially the same as those which existed in AS 2293.1—1987* Changes of significance that have been made include the following: (a) Revision of the form of specifying the colours of exit signs (see Clause 3.6) (b) Revision of the requirements for the provision of a test switch, for self-contained emergency luminaires and exit signs (see Clause 4.3.2) (c) Addition of a requirement for battery circuits to be protected from excessive discharge currents in the event of fault conditions (see Clause 4.4.4) (d) Alteration of the requirements for battery chargers, including a new test to assess performance under short circuit condititions (see Clause 4.5 and Paragraph D4, Appendix D) (e) The inclusion of requirements for self-contained emergency luminaires and exit signs with automatic discharge testing facilities (see Clause 4.8 and Paragraph D3 of Appendix D) (f) Modification of the photometric testing conditions and the associated requirements for establishing luminaire classifications (see Paragraphs C2.1 and C3 of Appendix C) Different requirements apply in Australia and in New Zealand with respect to the form and dimensions of exit signs (see Clause 3.4) The differences arise from differing regulatory practices in the respective countries It is anticipated that these differences will be reconciled in the near future by adoption of exit signs of the pictogram type (i.e symbolic outline of a person moving towards an open door), when requirements for internally illuminated forms of these signs are agreed internationally With reference to requirements for radio interference suppression (see Clause 1.5), compliance with AS/NZS 4051§ is already mandatory in New Zealand under regulations issued by the Ministry of Commerce In Australia, the Spectrum Management Agency has declared that compliance with AS/NZS 4051 will be required under Commonwealth legislation from January 1996 * AS 2293.1 — 1987 Emergency evacuation lighting in buildings Part 1: Design and

classification marked on the luminaire, e.g a test report from an appropriately accredited laboratory 2.3 ILLUMINATION AT SWITCH ON 2.3.1 Maximum delay Emergency luminaires shall provide a light output of at least— (a) 10% of the reference value within s of loss of the normal supply; and (b) 80% of the reference value within 15 s of loss of the normal supply The reference value shall be taken as the luminous intensity assigned in terms of the classification procedure of Paragraph C3.2 of Appendix C The requirements of Items (a) and (b) shall apply both when the emergency luminaires are initially switched on (i.e cold start) and when the emergency luminaires are switched on immediately after operation for a period of 15 (i.e hot start) NOTE: The provision of a light output of at least 10% of the reference value within s of energization is specified to minimize the possibility of panic occurring among the occupants of the building 2.3.2 Conditions for assessing compliance with Clause 2.3.1 For the purpose of assessing compliance with the requirements of Clause 2.3.1, the following conditions shall apply: (a) Before the emergency luminaires are operated they shall be

licence only Storage, distribution or use on network prohibited C1 BASIS OF CLASSIFICATION The system described in this Appendix for the classification of emergency luminaires is based on the following considerations: (a) The general shape of the intensity distribution curves in the transverse (C 0) and longitudinal (C 90) vertical planes through the luminaire (see Figures C1 and C2) The classification for each plane is considered separately (b) The luminous intensity in the downward vertical direction This intensity is used for convenience, but is related to the intensities at other angles by the characteristic distribution shape The purpose of the classification is to facilitate the specification of requirements, in terms of luminaire mounting height and spacing, to simplify both the design of emergency lighting installations and the assessment of compliance FIGURE C1 VERTICAL PLANES THROUGH EMERGENCY LUMINAIRE FOR MEASUREMENTS OF LUMINOUS INTENSITY C2 TEST CONDITIONS C2.1 General The emergency luminaire shall be tested in accordance with the requirements of this Appendix under the appropriate conditions specified in AS 1680.3 C2.2 Alternative luminaire combinations Where the emergency luminaire is designed for use in several different combinations (e.g the same basic luminaire with different diffusers) each combination shall be tested as specified and information shall be marked on the luminaire to enable identification of the classification for each of the combinations COPYRIGHT 27 AS / NZS 2293.3:1995 C2.3 Mounting position The emergency luminaire shall be mounted in the horizontal plane for the purpose of the tests unless of a type which is not designed for this application Where designed for use in other mounting positions, e.g on a wall or other vertical surface, the emergency luminaire shall be tested in each of the designed mounting positions and information shall be marked on the luminaire to enable identification of the classification for each mounting position NOTE: Marking on the luminaire to relate the classification to the mounting position is not required where the luminaire is designed for mounting only in the horizontal plane C2.4 Test voltage and current For the photometry necessary to establish the classification of an emergency luminaire, the following conditions shall apply: (a) Centrally supplied luminaires The test voltage shall be as follows: (i) For connection to d.c supply — 80% of the rated voltage of the luminaire (ii) For connection to a.c supply from central inverter —90% of the rated voltage of the luminaire Where the luminaire is marked for operation within a range of voltages, the lowest marked voltage shall be used as the basis for determining the test voltage Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited (b) Self-contained emergency luminaires The test voltage shall be as determined in accordance with Paragraph D2.1 of Appendix D The batteries shall be disconnected and replaced by a separate d.c supply of the required voltage The current delivered to the luminaire during the test shall be within 5% of the value determined in accordance with Paragraph D2.1 of Appendix D; however, this requirement need not apply if the tests of Appendices C and D are conducted sequentially in the same laboratory C3 PROCEDURE FOR DERIVING THE LUMINAIRE CLASSIFICATION C3.1 General procedure The luminous intensities emitted by the luminaire shall be measured in both the C0 and C90 planes at intervals of not more than 5°, from the downward vertical direction, up to and including 90° above the downward vertical The luminaire shall then be assigned an alphanumeric classification in accordance with Paragraph C3.2 NOTE: The luminous intensity data required above is of an abbreviated form, for use in establishing the classification of emergency luminaires in accordance with this Appendix Where maximum spacings of emergency luminaires are to be determined by illuminance calculations (see AS/NZS 2293.1), more comprehensive luminous intensity data in accordance with AS 1680.3 will be required Where the luminous intensities emitted on either side of the downward vertical in the C or C90 plane differ, i.e the luminaire has an asymmetric light distribution in the particular plane, the luminous intensities for the half-plane which produces the lowest classification shall be used The luminaire may be assigned more than one classification provided that it complies with the requirements which are applicable for each of the classifications assigned Different classifications may be assigned in the C and C90 planes (see Figure C1) provided that each classification is specifically related to the relevant plane Example Where a luminaire is assigned a C classification in the C0 plane and a B classification in the C90 plane, the luminaire would be marked as follows: C0/C C90/B COPYRIGHT AS / NZS 2293.3:1995 28 Where the luminaire is not marked in accordance with Clause 2.5(b) and the location of the C0 plane is not obvious, luminous intensities shall be measured in at least eight equally-spaced vertical planes A single classification, corresponding to the lowest classification afforded by any one of the measurement planes, shall be adopted Where lamps of differing light output are likely to be used, the luminaire shall be classified separately for each condition of use Each alternative classification shall be indicated, together with information which will identify the lamp to which the particular classification relates C3.2 Method of assigning the classification C3.2.1 General The classification assigned to an emergency luminaire shall comprise the combination of an alphabetic and a numerical designation, determined in accordance with Paragraph C3.2.2 and Paragraph C3.2.3 respectively C3.2.2 Alphabetic component of the classification The alphabetic component of the classification, in the form of the letters A, B, C, D or E, shall be assigned in accordance with the following procedure, based on the general shape of the luminous intensity distribution in the appropriate vertical plane (see Paragraph C3.1) NOTE: Figure C2 illustrates the characteristic shape of the luminous intensity distribution curves for the general classes of emergency luminaire that are specified in this Standard Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited The luminous intensities at each of the measured angles shall be not less than the values determined from the following equations, as applicable: (a) For Class A emergency luminaires — (b) For Class B emergency luminaires — (c) For Class C emergency luminaires — (d) For Class D emergency luminaires — (e) For Class E emergency luminaires — (for γ ≤ 70°) C1 (for γ ≤ 70°) C2 (for γ ≤ 70°) C3 (for γ ≤ 70°) C4 (for γ ≤ 30°) C5 (for γ > 30° ≤ 65°) C6 where Ip = luminous intensity emitted at the particular angle, in candelas (cd) Io = luminous intensity in the downward vertical direction, assigned in accordance with Paragraph C3.2.3, in candelas (cd) γ = angle from the downward vertical at which the luminous intensity is measured, in degrees The luminous intensity for any one measurement angle up to and including 30° from the downward vertical may, for that angle only, be up to 20% below the minimum value determined from the relevant equation COPYRIGHT 29 AS / NZS 2293.3:1995 C3.2.3 Numerical component of the classification The numerical component of the classification shall be assigned corresponding to any value in the following series which is equal to or less than the actual luminous intensity in the downward vertical direction: 1, 1.25, 1.6, 2, 2.5, 3.2, 4, 5, 6.3, 8, 10, 12.5, 16, 20, 25, 32, 40, 50 NOTE: The above values are based on the R10 series of preferred numbers in AS 2752 C4 MARKING OF INFORMATION RELATING TO THE LUMINAIRE CLASSIFICATION Emergency luminaires shall be clearly and durably marked with the specific classifications determined in accordance with this Appendix in respect of the following factors, as applicable: Differences in the luminous intensities emitted in the transverse (C 0) and longitudinal (C 90) vertical planes (see Paragraph C3.1) (b) Type of lamps with which it may be used (see Paragraph C3.1) (c) Alternative forms in which the luminaire may be used (see Paragraph C2.2) (d) Designed mounting positions (see Paragraph C2.3) Licensed to LUU MINH LUAN on 25 Feb

luminaire and exit sign shall be subjected to a high temperature test and a low temperature test, conducted in that order in accordance with Tables D1 and D2 respectively, and shall comply with the appropriate requirements stated therein Where a range of self-contained emergency luminaires or exit signs utilize the same circuit, components and enclosure, each luminaire or exit sign need not be tested, provided that— (a) the luminaire or exit sign selected for the high temperature test represents the form that will produce the highest internal temperatures, e.g use maintained mode, polished reflector, dense diffuser; and (b) the luminaire or exit sign selected for the low temperature test represents the form that will produce the lowest internal temperatures, e.g use non-maintained mode, diffuse reflector, operate without diffuser Where there is doubt about which luminaire or exit sign should be selected in accordance with Items (a) and (b), each luminaire or exit sign in the range shall be operated at ambient temperature of 25 ±2°C and the internal temperatures measured adjacent to the battery, until stable temperature conditions are attained Test reports shall clearly indicate, by reference to catalogue numbers or other suitable identification markings, the luminaires or exit signs selected for testing and the range of emergency luminaires or exit signs which they represent D1.2 General conditioning The three cycles of each test procedure shall follow sequentially in the order specified The interval between successive cycles shall not exceed 12 h, during which time the ambient temperature shall be maintained at the specified value The battery voltage shall be monitored continuously throughout each cycle All other parameters shall be monitored at intervals of not more than For the purpose of the tests, the ambient temperature shall be taken as the dry-bulb temperature reading within the test room or enclosure under still air conditions During measurement, the temperature-sensing element shall be shielded from radiation from the luminaire or exit sign under test All voltage measurements shall be taken while the battery is being charged or discharged, as appropriate D2 LIGHT OUTPUT D2.1 Self-contained emergency luminaires Each design/type of self-contained emergency luminaire shall, in addition to complying with this Appendix, be tested
