DIGITAL ADDRESSABLE LIGHTING INTERFACE –

Part 202: Particular requirements for control gear –
Self-contained emergency lighting (device type 1)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 62386-202 has been prepared by IEC technical committee 34: Lighting. It is an International
Standard.
This second edition cancels and replaces the first edition published in 2009. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) scope updated,
b) hardwired switch operation can be disabled,
c) installation inhibit feature added,
d) memory bank added,
e) modes of operation clarified, with some changes and additions,
f) command added to enter extended emergency mode,

182 FOREWORD
183 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
184 all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
185 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
186 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
187 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
188 Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
189 in the subject dealt with may participate in this preparatory work. International, governmental and non-
190 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
191 with the International Organization for Standardization (ISO) in accordance with conditions determined by
192 agreement between the two organizations.
193 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
194 consensus of opinion on the relevant subjects since each technical committee has representation from all
195 interested IEC National Committees.
196 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
197 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
198 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
199 misinterpretation by any end user.
200 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
201 transparently to the maximum extent possible in their national and regional publications. Any divergence
202 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
203 the latter.
204 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
205 declared to be in conformity with an IEC Publication.
206 6) All users should ensure that they have the latest edition of this publication.
207 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
208 members of its technical committees and IEC National Committees for any personal injury, property damage or
209 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
210 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
211 Publications.
212 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
213 indispensable for the correct application of this publication.
214 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
215 rights. IEC shall not be held responsible for identifying any or all such patent rights.
216 International Standard IEC 62386-202 has been prepared by subcommittee 34C: Auxiliaries for
217 lamps, of IEC technical committee 34: Lamps and related equipment.

236 INTRODUCTION
237
238 IEC 62386 contains several parts, referred to as a series. The 1xx series includes the basic
239 specifications. Part 101 contains general requirements for system components, Part 102
240 extends this information with general requirements for control gear and Part 103 extends it
241 further with general requirements for control devices.
242 The 2xx parts extend the general requirements for control gear with lamp specific extensions
243 (mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
244 features.
245 The 3xx parts extend the general requirements for control devices with input device specific
246 extensions describing the instance types as well as some common features that can be
247 combined with multiple instance types.
248 This second edition of IEC 62386-202 is published in conjunction with IEC 62386-101:– and
249 IEC 62386-102:– and with the various parts that make up the IEC 62386-2xx series for control
250 gear, together with IEC 62386-103:– and the various parts that make up the IEC 62386-3xx
251 series of particular requirements for control devices. The division into separately published
252 parts provides for ease of future amendments and revisions. Additional requirements will be
253 added as and when a need for them is recognised.
254 The setup of the standard is graphically represented in Figure 1 below.
