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,

---------------------- Page: 7 ----------------------
– 6 – IEC 62386-202:2022 © IEC 2022
g) command added to extend time in duration test mode.
The text of this International Standard is based on the following documents:
Draft Report on voting
34/986/FDIS 34/1000/RVD

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications.
This Part 202 of IEC 62386 is intended to be used in conjunction with:
• Part 101, which contains general requirements for system components;
• Part 102, which contains general requirements for control gear.
A list of all parts in the IEC 62386 series, published under the general title Digital addressable
lighting interface, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

IMPORTANT – The "colour inside" logo on the cover page of this document indicates that it
contains colours which are considered to be useful for the correct understanding of its
contents. Users should therefore print this document using a colour printer.

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The IEC 62386 series specifies a bus
system for control by digital signals of electronic lighting equipment. The IEC 62386-1xx series
includes the basic specifications. Part 101 contains general requirements for system
components, Part 102 extends this information with general requirements for control gear and
Part 103 extends it further with general requirements for control devices. Part 104 and Part 105
can be applied to control gear or control devices. Part 104 gives requirements for wireless and
alternative wired system components. Part 105 describes firmware transfer. Part 150 gives
requirements for an auxiliary power supply which can be stand-alone, or built into control gear
or control devices.
The IEC 62386-2xx series extends the general requirements for control gear with lamp specific
extensions (mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear
specific features.
The IEC 62386-3xx series extends the general requirements for control devices with input
device specific extensions describing the instance types as well as some common features that
can be combined with multiple instance types.
This second edition of IEC 62386-202 is intended to be used in conjunction with IEC 62386-101
and IEC 62386-102 and with the various parts that make up the IEC 62386-2xx series for control
gear, and can be used together with IEC 62386-103 and the various parts that make up the
IEC 62386-3xx series of particular requirements for control devices. The division into separately
published parts provides for ease of future amendments and revisions. Additional requirements
will be added as and when a need for them is recognised.
The setup of the standards is graphically represented in Figure 1 below.
