Special national condition: National characteristic or practice that cannot be changed even over a

Clause Special national condition
Foreword United Kingdom
Add an additional paragraph:
"Fireman’s switches which cover applications suited to light industrial units, retail
units and petrol station forecourts fall under the scope of EN 60947-3."
since the scope of EN 60669-1 only covers household and similar fixed electrical
installations.
13.108 France
The enclosure of the fireman’s switch and of the actuating handle could be of an
other colour than red if it is equipped with an red illuminated indicator according to
13.107.
The colours yellow, green and blue are not allowed (according to NF X 08-003-1).
13.108 Portugal
Fireman’s switches may have colours different from red for the enclosure and
different from black for the actuating handle, if they are equipped with a red
illuminated indicator, according to 13.107.

A-deviations
A-deviation: National deviation due to regulations, the alteration of which is for the time being outside
the competence of the CENELEC national member.
This European Standard falls under Directive 2006/95/EC.
NOTE (from CEN/CENELEC IR Part 2:2011, 2.17) Where standards fall under EU Directives, it is the view of the Commission
of the European Communities (OJ No C 59, 1982-03-09) that the effect of the decision of the Court of Justice in case 815/79
Cremonini/Vrankovich (European Court Reports 1980, p. 3583) is that compliance with A-deviations is no longer mandatory and
that the free movement of products complying with such a standard should not be restricted except under the safeguard
procedure provided for in the relevant Directive.
In the relevant CENELEC countries these A-deviations are valid instead of the provisions of the European
Standard/Harmonization Document until they have been removed.

Part 2-6: Particular requirements –
Fireman's switches for exterior

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.
International Standard IEC 60669-2-6 has been prepared by subcommittee 23B: Plugs,
socket-outlets and switches, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
CDV Report on voting
23B/990/CDV 23B/1032/RVC
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

This part of IEC 60669 is to be used in conjunction with IEC 60669-1:1998,
Amendment 1:1999 and Amendment 2:2006. It lists the changes necessary to convert that
standard into a specific standard for fireman’s switches.
In this publication, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– notes: in smaller roman type.
Subclauses, figures tables or notes which are additional to those in part 1 are numbered
starting from 101.
A list of all the parts in the IEC 60669 series, published under the general title Switches for
household and similar fixed electrical installations, can be found on the IEC website.
The following differing practices exist in the countries indicated below.
– Clause 1: in all CENELEC countries, the rated voltage for the signs and luminous-
discharge-tube installations is higher than 1 kV but lower than 10 kV and these should be
in accordance with EN 50107 series.
– Clause 1: in Italy, installation rules and/or laws may require different protection switching
devices in order to comply with the function given in the scope of this standard.
– Subclause 13.108: in France, the enclosure of the fireman’s switch and of the actuating
handle could be of another colour than red if the fireman’s switch is equipped with a red
illuminated indicator according to 13.107. The colours yellow, green and blue are not
allowed (according to ISO 3864-1:2002).
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
