and fire alarm systems”, the secretariat of which is held by BSI.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following

countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,

Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany,

Introduction

Guidelines covering sound systems for use during an emergency are published by different organizations

within Europe. The intention of this Technical Specification is to draw together these documents and provide

up-to-date guidelines for planning, design, installation, commissioning, use, maintenance and modification of

emergency sound systems throughout Europe.

Sound systems for use in emergency, whether automatically triggered, manually triggered, or both, are

commonly called voice alarm systems.

It is not intended that this Technical Specification should override existing local, regional or national

regulations. It is expected for a considerable (and as yet unspecified) period that these guidelines will coexist

with other codes. However, it is hoped that the availability of a common set of guidelines will assist in the

harmonization of practice and standards for voice alarm systems throughout Europe.

This document gives recommendations. These recommendations can be made mandatory by being specified

within other document(s). For example, an authority having jurisdiction empowered under local, regional or

national legislation can require compliance with this document. Equally a contract between a purchaser and a

supplier can specify compliance that may then become mandatory under contract law.

The purpose of a voice alarm system is to provide intelligible warning to person(s) within, or in the vicinity of, a

building in which an emergency has occurred and to enable such person(s) to take appropriate measures

according to an emergency management plan.

Voice alarm systems are often used instead of alarm sounders (see EN 54-3) because the meaning of an

alarm signal may not be clear to untrained building occupants and so time may be spent deciding what it

means and then further time may be spent deciding what to do.

This document contains specific recommendations for the design, installation, commissioning, use, and

maintenance of voice alarm systems and is based on the format used in CEN/TS 54-14.

The main principles on which the guidelines are based are given in the body of this Technical Specification.

Detailed recommendations by which these principles may be satisfied are given in annexes.

1 Scope

This Technical Specification provides guidelines for the planning, design, installation, commissioning, use,

maintenance and modification of voice alarm systems in and around buildings that broadcast information for

the protection of lives in a fire emergency. See EN 54-1:2011, Figure 1, item C and item M.

These guidelines cover voice alarm systems that are triggered automatically by a fire detection and fire alarm

system or that are manually triggered, or both.

This Technical Specification does not apply to fire detection and fire alarm systems that only use voice

sounders, bells or sounders or a combination of these.
NOTE 1 CEN/TS 54-14 provides guidelines for these systems.

This Technical Specification does not exclude the use of voice alarm systems for emergency purposes other

than fire emergency.

NOTE 2 When used for emergencies other than those due to fire, it might be appropriate to modify the guidance in this

Technical Specification.

This Technical Specification does not exclude the use of voice alarm systems for non-emergency purposes.

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated references,

the latest edition of the referenced document (including any amendments) applies.

EN 54-1:2011, Fire detection and fire alarm systems - Part 1: Introduction
3 Terms and definitions, symbols and abbreviations

For the purposes of this document, the definitions, symbols and abbreviations given in EN 54-1:2011 and the

following apply.
3.1 Terms and definitions
3.1.1
acceptance

decision that the installed system meets the requirements of a previously agreed specification

3.1.2
acoustically different area
ADA

subdivision of a voice alarm zone, which may be an enclosed or otherwise physically defined space,

characterized by an individual reverberation time and/or ambient noise level
Note 1 to entry: ADA is also known as an acoustically distinguishable area.
3.1.3
alarm signal
visual, audible or tactile indication of a fire or other emergency

EXAMPLES Fire, bomb alert, industrial accident, civil commotion, terrorist attack.

---------------------- Page: 9 ----------------------
SIST-TS CEN/TS 54-32:2015
CEN/TS 54-32:2015 (E)
3.1.4
alarm load

maximum current required to operate the voice alarm system in the voice alarm condition

3.1.5
ambient noise level

ambient sound pressure normally present in an ADA in dB, normally measured using equivalent sound

pressure level, L but may be measured using L , depending on the nature of the noise

eqT 10

Note 1 to entry: The level of ambient noise is measured across all the octave bands from 125 Hz to 8 kHz. The results

can be used to correct STI calculations and to assist with electro-acoustic system design.

Note 2 to entry: L is the A-weighted sound pressure level of noise varying over a period of time, T (normally 10 min)

eqT

expressed as the amount of average energy and is the measurement method normally used when there is long-term

background noise, such as from extraction fans.

Note 3 to entry: L is the sound pressure level exceeded for 10 % of the measurement period calculated by statistical

analysis over a specified time period, T and is the measurement method normally used when background noise varies

significantly.

Note 4 to entry: Where the ambient noise level exceeds 90 dB, satisfactory speech intelligibility becomes increasingly

difficult to achieve because of the auditory-masking effect.
3.1.6
approval

agreement by a third-party that the installed system satisfies the requirements of the third-party

3.1.7
approval body

body accepted by an authority having jurisdiction or other competent organization as having the expertise

necessary to assess the compliance of the installed system with this Technical Specification

3.1.8
area of coverage

area inside or outside a building where the voice alarm system should meet the recommendations of this

Technical Specification
3.1.9
arithmetic mean

value obtained by dividing the sum of a set of quantities by the number of quantities in the set

Note 1 to entry: The arithmetic mean l is given by the following formula:
l aa++ a++... a
( )
av 12 3 N
where
is a real number (measurement value), and
N is the number of measurement values.

3.1.10
attention-drawing signal
tone that is broadcast to attract attention at the start of an emergency message

Note 1 to entry: The level of the attention-drawing signal is measured using the A-weighted equivalent continuous

sound pressure level method, L .
AeqT
3.1.11
audibility
property of a sound that allows it to be heard among other sounds

Note 1 to entry: The fact that a message is audible does not mean that it is intelligible.

3.1.12
auditory masking

process by which the threshold of hearing (audibility) of one sound is increased by the presence of another

(masking) sound

Note 1 to entry: In the STI method, auditory masking is also referred to as the upward spread of masking.

3.1.13
authority having jurisdiction
AHJ

body having powers to approve the voice alarm system provided under local, regional, national or European

legislation
