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.

Introduction
General
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 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 may 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 may 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 may 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 as conforming to
the requirements for a system.
Open Descriptions to express product performance
Many of the product standards in the EN 54 series fall under the Construction Product Regulation
(305/2011/EU – CPR) and, as such, they are prepared for citation in the Official Journal of the European
Union (OJEU) as Harmonized standards (hENs). This regulation places constraints on how the EN 54
5

---------------------- Page: 7 ----------------------
oSIST prEN 54-1:2020
prEN 54-1:2020 (E)
products standards are prepared and an approach using “open descriptions” is being phased in to
realize the “common technical language” expected by the CPR and thus facilitate ongoing citation in the
OJEU.
In the past the EN 54 series specified the minimum performance using pass/fail criteria. In the CPR the
pass/fail criteria is not allowed. This contradiction can be overcome by using descriptions of
performance, which are allowed by the CPR, particullarly if the descriptions are open (allows open trade
for products with different performances). This “open descriptions” approach is being phased into the
EN 54 series and introduces standard descriptors “X” and “0” to express, respectively, when an optional
characteristic is not provided (X) and when the performance of a characteristic is not within defined
criteria (0). Other descriptors (e.g. “1”, “2”, “A1”, “A2”) express when the performance of a characteristic
is within defined criteria. Together, these descriptors establish a “common technical language” which
can be used by member states to specify the requirements for FDAS components.
This “open descriptions” approach is being phased into the EN 54 series. It is easy to recognize those
parts which have adopted the approach because the descriptors and corresponding criteria for each
product characteristic are expressed in tabular form.

2) to determine whether these signals correspond to a fire alarm condition;
3) to indicate any such fire alarm condition audibly and visually;
4) to indicate the location of the danger.
b) is used to monitor correct functioning of the system and give audible and visible warning of any
faults (e.g. short circuit, line breakage, or fault in the power supply); and, if necessary is able to pass
on the fault warning through fault warning routing equipment to a fault warning receiving centre;
c) if necessary, is able to pass on the fire alarm signal; for example:
i) to audible or visible fire alarm devices or to a voice alarm system;
ii) to the fire alarm routing function to a fire alarm receiving centre;
iii) to the control function for fire protection equipment or systems;
iv) to fire brigade panel;
v) to other systems or equipment not covered by EN 54.
