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

---------------------- 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.
