Foreword
This document (CEN/TR 1568:2003) has been prepared by Technical Committee CEN/TC 72, "Fire detection and
fire alarm systems", the secretariat of which is held by BSI.
Introduction
Since the publication of EN 54-2:1997, it has been found that some clauses are open to different interpretations,
which have given rise to discussions about the intended meaning of certain requirements.
This Technical Report has been written with the objective of providing further information to the users of EN 54-
2:1997, in particular to those who were not involved in the elaboration of this standard, in order to avoid these
misinterpretations and to improve the understanding of the requirements of the standard.
Furthermore, this Technical Report should help during discussions between manufacturers, test houses and
certification bodies.
This Technical Report is intended to be read in conjunction with EN 54-2:1997, and it is assumed that the readers
have sufficient technical background and professional knowledge in the field.
Some of the clauses for which interpretations are provided are also the subject of amendments, currently under
elaboration in CEN/TC 72/WG 7. As soon as these amendments are published, the relevant clauses will take
precedence over the interpretations.
1 Scope
This Technical Report provides additional information on the requirements of the European Standard EN 54-2:
1997, in order to avoid misinterpretations of the clauses and to improve the understanding of the requirements of
the standard.
The interpretations are produced in the form of a table where in the first column the clauses of EN 54-2:1997 are
listed for which an interpretation is considered necessary. In the second column the subject and in the third column
the interpretation is given.
This Technical Report does not include additional requirements and should only be used in connection with EN 54-
2: 1997. This Technical report is not a stand-alone document.
2 Normative references

normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this Technical
Report only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.

4 General Requirements A manufacturer cannot claim to comply with an “option with
Optional functions with requirements” as specified in EN 54-2 unless all of the
requirements requirements are fulfilled. If the c.i.e. provides a function
which is similar but not identical with an optional function
with requirements as specified in EN 54-2, this is an option
without requirements and compliance with the second
paragraph of clause 4 has to be checked either by testing or
assessment. In order to avoid confusion, the name of this
option within the documentation of the c.i.e. must be
different from the name of an optional function in EN 54-2.
5.1.1 Display of functional The indication of the “Test Condition” is mandatory if this

5.2 Display of indications Mandatory indications means all visible and audible
Clear identification of indications as required by this standard, relating both to
mandatory indications functions which shall be provided on all c.i.e. and those
optional functions with requirements which the manufacturer
includes. It shall be possible to unambiguously distinguish
all such indications, except in those cases where the
standard explicitly permits that the indication may be the
same. For example:
- the audible indication of a fire alarm [7.4] may be the
same as that for a fault [8.6];
- the visible indication, by means of light emitting
indicators, of a disabled zone [9.4.1 a)] may be the
same as that for the zone in the test state [10.2 b)].
5.3 Indications on If the same alphanumeric display is used both for indications
alphanumeric displays as specified in EN 54-2 and for event logging, mandatory
event logging indications must not be suppressed. It is, however, allowed
to use a separate window of the alphanumeric display for
event logging. Such a facility would be considered as an
option without requirements.
5.4 Indication of the supply The indication, that the c.i.e. is supplied with power (mains
with power or battery) shall be given as long as power is supplied. It
cannot be off, when the mains fails and the c.i.e. is powered
by the battery.
