Foreword
This document (prEN 54-3:2009) has been prepared by Technical Committee CEN/TC 72 “Fire detection and
fire alarm systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This edition of EN 54-3 cancels and replaces EN 54-3:2001, EN 54-3: 2001/A1: 2002 and EN 54-3: 2001/A2:
2006, which have been extensively revised.

Introduction
The purpose of a fire alarm sounder is to warn person(s) within, or in the vicinity of, a building of the
occurrence of a fire emergency situation in order to enable such a person(s) to take appropriate measures.
This standard recognizes that the exact nature of the sound requirements, i.e. its frequency range, temporal
pattern and output level will vary according to the nature of the installation, the type of risk present and
appropriate measures to be taken, the type of signals used by other non-emergency alarms (see, for example,
EN 457) and national differences in custom and practice. The resulting standard specifies, therefore, a
common method for the testing of the operational performance of sounders against the specification declared
by the manufacturer rather than imposing common requirements.
Attention is drawn to ISO 8201:1987, Acoustics – Audible emergency evacuation signal, the international
standard which specifies the temporal pattern and the required sound pressure level of an audible emergency
evacuation signal.
This standard gives common requirements for the construction and robustness of sounders as well as for their
performance under climatic, mechanical and electrical interference conditions which are likely to occur in the
service environment. The sounders have been classified in either an indoor or an outdoor application
environment category.
In fire detection and fire alarm systems, voice sounders are used as alarm devices for warning the occupants
of a building of the occurrence of a fire risk, using a combination of an attention drawing signal and dedicated
voice message(s). The requirements, test methods and performance criteria specified in EN 54-3:2001 for
sounders are also applicable to voice sounders. Additional requirements, test methods and performance
criteria specific to voice sounders are also incorporated.
prEN 54-3:2009 (E)
1 Scope
This European Standard specifies the requirements, test methods and performance criteria for fire alarm
sounders in a fixed installation intended to signal an audible warning of fire detection and fire alarm systems
and the occupants of a building. It is intended to cover only those devices which derive their operating power
by means of a physical electrical connection to external source such as a fire alarm system.
This standard is also intended to cover voice sounders by the application of specific requirements, tests and
performance criteria.
This standard specifies fire alarm sounders for two types of application environment, Type A for indoor use
and Type B for outdoor use.
This standard does not cover:
a) loudspeaker type devices primarily intended for emitting emergency voice messages that are generated
from an external audio source;
b) supervisory sounders, for example, within the control and indicating equipment.

4.1 Compliance
In order to comply with this standard, sounders shall meet the requirements of this clause, which shall be verified
by visual inspection or engineering assessment and shall be tested as described in clause 5 and shall meet the
requirements of the tests.
4.2 Sound level
The standard requires that the manufacturer declare sound levels in the data required under 4.6.2. The
manufacturer may declare different sound levels for operation under different conditions, for example, when
operating on different voltage ranges or with different sound patterns. If this is the case the sound level of
each specimen shall be measured under each mode of operation (see 5.3).
prEN 54-3:2009 (E)
When tested in accordance with 5.3 the fire alarm sounder shall produce A-weighted sound levels of at least
65 dB in one direction.
NOTE A maximum sound level received by occupants may be specified by National regulations.
4.3 Frequency and sound pattern
This standard covers sounders which produce different frequencies and sound patterns and, therefore, does
not specify a minimum and maximum frequency or specific sound pattern. However, the main sound
frequency(ies), frequency range(s) and sound pattern(s) shall be declared in the data required under 4.8.2.
NOTE 1 The sound patterns and frequencies required may vary in different countries. Reference needs to be made to
local regulations.
NOTE 2 Annex C gives information on some of the national standards that applies in Europe and on ISO 8201.
ISO 8201 specifies a standard international evacuate signal.
4.4 Requirements for voice sounders
4.4.1 General
Voice sounders shall be capable of producing an audible warning signal and a voice message or messages.
All messages related to fire safety shall be declared by the manufacturer and shall be considered by the
testing authority. The message determined to be worst case shall be subject to the conformance assessment.
NOTE 1 When selecting the worst case message, message length, loudness and repetition timing should be
considered.
For messages that require immediate action, the warning signal and message sequence broadcast by the
device shall be within the following limits:
 warning signal, lasting for 2 s to 10 s; followed by
 silence, lasting for 0,25 s to 2 s; followed by
 voice message; followed by
 silence, lasting for 0,25 s to 5 s.
The time for each cycle shall not exceed 30 s.
The periods of silence may need to be longer than indicated in certain circumstances, for example in spaces
with long reverberation times, but shall not be such that the time between the start of each cycle exceeds
30 s.
NOTE 2 For other messages, it is permitted to extend either or both the silence period after the voice message and the
period within which the message is repeated.
Access to the message recording function shall be restricted as specified in 4.7.4.
NOTE 3 Persons trained in the proper use of microphones should be used to record the messages. The recordings
should be made in a room with a controlled acoustic environment having an ambient noise level not greater than 30 dBA
and a reverberation time not greater than 0,5 s from 150 Hz to 10 kHz.

If the manufacturer has declared different sound levels for operation under different conditions (see 4.8.2), then,
unless otherwise specified in the test procedure, the tests shall be conducted under one selected mode of
operation only. Selection of the mode of operation shall be made with the aim to use that which consumes the
most power. This will normally be the most continuous or the loudest mode.
NOTE All modes of operation and all voltages are tested in 5.3.
5.1.3 Mounting arrangements
Unless otherwise specified, the specimen shall be mounted by its normal means of attachment in accordance
with the manufacturer's instructions on a flat rigid backing board. If these instructions describe more than one
method of mounting then the method considered to be most unfavourable shall be chosen for each test.
The detailed mounting arrangements are given in Annex A or Annex B for the different sound level tests used.
5.1.4 Tolerances
The tolerances for the environmental test parameters shall be given in the basic reference standards for the
test (e.g. the relevant part of EN 60068).
If a specific tolerance or deviation limit is not specified in a requirement or test procedure, then a deviation
limit of ± 5% shall be applied.
5.1.5 Provision for tests
The following shall be provided for testing compliance with this European Standard:
prEN 54-3:2009 (E)
eight specimens of type A or ten specimens of type B sounder with any mounting, bases, boxes or
accessories etc.;
any equipment, such as control and indicating equipment, as may be necessary for the correct operation of
the device in accordance with the manufacturer's specification;
the data required in 4.8.2.
The specimens submitted shall be deemed representative of the manufacturer's normal production with
regard to their construction and settings.
NOTE The details of the power supply equipment used and/or the equipment used for generating the control
signal(s) should be given I the test report.
5.1.6 Test schedule
The specimens shall be tested and inspected according to the schedule given in Table 1.
All the specimens shall be first submitted to the reproducibility test described in 5.2. On completion of the
reproducibility test, the specimen with the least loud sound level shall be numbered 1 and the rest arbitrarily
numbered from 2 to 8 for type A or 2 to 10 for type B.
Unless otherwise required by the test procedure, the mode of operation selected for conducting the
reproducibility test shall be used for the other tests.
Where, after one of the test specified in 5.5 to 5.16 the sound level of the specimen differs from that measured
during the reproducibility test by more than 6 dB, a new specimen shall be used for the next test on the
schedule for that specimen. The sound level shall be first measured as specified in 5.2.
The tests on an individual specimen may be carried out in any order except that the reproducibility test (5.2)
shall be performed first on all specimens and the tests on specimens 1 and 2 shall be carried out in the order
listed (i.e. 5.20 last).
5.2 Reproducibility
5.2.1 Object of the test
To show that the sound output of the sounder does not vary unduly from specimen to specimen and to
establish sound output data for comparison with the sound output measured during and/or after the
environmental tests specified in this standard.
5.2.2 Test procedure
The A-weighted sound levels of all the specimens shall be measured as described in Annex B.
The measurement shall be recorded in dB for each specimen and the sound level of the loudest and the least
L L
max min
loud specimen shall be represented by and respectively.
5.2.3 Test requirements
The audible alarm device shall be deemed to comply with the requirement of this clause if the difference

5.3 Operational performance
5.3.1 Object of the test
To check that the sound levels declared by the manufacturer can be achieved within the specified range(s) of
supply parameters (e.g. voltage).and is not unduly dependent on these parameters.
5.3.2 Test procedure
The sound level of the specimen shall be measured in free field conditions using the test method described in
Annex A with the supply parameters at the maximum and minimum of the specified range(s) [see 4.8.2 a) and
b)].
If the manufacturer has declared different sound levels and different operating frequencies for different modes
of operation [see 4.8.2], then the sound level of the specimen shall be measured under each mode.
5.3.3 Test requirements
The sounder shall be deemed to comply with the requirements of this clause if, for each mode of operation:
the A-weighted sound level is greater than 65 dB in at least one direction;
f) the sound level measured at each of the specified angles is not less than that declared by the
manufacturer [see 4.8.2 c)].

To show that the sound level does not change significantly after prolonged operation of the audible alarm device.
5.4.2 Test procedure
The specimen shall be subjected to the following durability cycle 100 times: the specimen shall be operated for
1 h at the maximum of the supply parameters declared by the manufacturer (see 4.8.2) and then shall be left in
the non-operating condition for 1 h. The sound level shall be measured as described in Annex B within 1 h of the
final period of operation.
5.4.3 Test requirement
The sounder shall be deemed to comply with the requirements of this clause if the A-weighted sound level
measured after 100 durability cycles does not decrease by more than 6 dB from that measured, for the same
specimen, under the same operating condition, in the reproducibility test (see 5.2).
