Introduction
This document gives the necessary information for the intended use of the series of EN 54 standards. The
EN 54 series applies to fire detection and fire alarm systems for buildings and civil engineering works
composed of several components that communicate for the purpose of detecting fire at the earliest
practicable moment, and:
— to give audible and/or visible signals to the occupants of the building who might be at risk from a
fire;
— to provide remote fire alarms to organizations having authority to take care of buildings and their
environment;
— to give signals to initiate, in the event of a fire, the operation of other fire protection and
equipment/systems.
The EN 54 series specifies:
— product characteristics, test methods and performance criteria against which the effectiveness and
reliability of the component parts of fire detection and fire alarm systems can be assessed and
declared;
— requirements for compatibility and connectability of components when combined into a system;
— guidelines for application of fire detection and fire alarm systems in buildings and civil engineering
works.
The EN 54 series may be used for other applications e.g. mines and ships, but one should consider the
specific nature of each application before use. Additional performance and environmental tests might be
necessary. This does not preclude the manufacture or use of systems having special characteristics
suitable for the protection of specific risks against specific hazards.
As this revision of the standard includes terms and definitions collated from specific parts of EN 54, there
can now be some duplication of terms and definitions in other parts. This situation will be corrected in
future revisions of the different parts of EN 54 so that definitions are defined only once and are applied
consistently throughout the series.
The functions of a fire detection and fire alarm system may be grouped to form subsystems such as a fire
detection subsystem and a voice alarm subsystem.
As the system is required to function satisfactorily, not only under fire conditions, but also when exposed
to conditions likely to be met in practice, the tests specified in the EN 54 series are intended to assess the
performance of the components and the system under such conditions.
The performance of components is assessed from the results obtained in the specified tests. This
performance does not ensure that this component will necessarily function correctly when connected
with another component also conforming to the relevant part of EN 54 (e.g. control and indicating
equipment with a fire detector), unless both components have been assessed together in accordance with
EN 54-13.
1 Scope
This document defines the terms and definitions that are used throughout the EN 54 series of standards.
It gives the principles on which each part of the series has been based and describes the functions carried
out by the components of a fire detection and fire alarm system.
This document applies to fire detection and fire alarm systems for buildings and civil engineering works.
This document does not apply to smoke alarm devices which are covered by EN 14604.
