Fire detection and fire alarm systems - Part 25: Components using radio links

This document specifies requirements, test methods and performance criteria for components used in fire alarms systems, installed in and around buildings, which use radio links to communicate. Where components work together and this requires knowledge of the system design, this document also specifies requirements on the system.
When the fire detection and fire alarm systems (FDAS) use wired and radio links, the relevant parts of EN 54 apply.

Brandmeldeanlagen - Teil 25: Bestandteile, die Hochfrequenz-Verbindungen nutzen

Dieses Dokument legt Anforderungen, Prüfverfahren und Leistungsmerkmale für Bestandteile von Brandmeldeanlagen, die Funkverbindungen nutzen und die in Brandmeldesystemen in und an Gebäuden verwendet werden.
Da das Zusammenwirken der Bestandteile Kenntnisse über das Brandmeldesystem erfordert, enthält dieses Dokument ebenfalls Systemanforderungen.
Werden in Brandmeldeanlagen (BMA) sowohl Leitungen als auch Funkverbindungen verwendet, gelten die entsprechenden Teile von EN 54.

Systèmes de détection et d'alarme incendie - Partie 25: Composants utilisant des liaisons radioélectriques

Le présent document définit les exigences, les méthodes d'essai et les criteres de performance pour les composants utilisés dans les systemes d'alarme incendie installés dans les bâtiments et autour de ceux-ci, qui utilisent des liaisons radioélectriques pour communiquer.
Lorsque les composants fonctionnent ensemble et que cela nécessite la connaissance de la conception du systeme, le présent document spécifie également les exigences relatives au systeme.
Lorsque les systemes de détection et d'alarme incendie (SDAI) emploient des liaisons radioélectriques et filaires, les parties concernées de la série EN 54 s'appliquent.

Sistemi za odkrivanje in javljanje požara ter alarmiranje - 25. del: Sestavni deli za radijske povezave

Ta evropski standard določa zahteve, preskusne metode in merila za delovanje za sestavne dele, ki se uporabljajo v sistemih za javljanje požara ter alarmiranje, nameščene v in okoli stavb, ki uporabljajo radijsko frekvenčne povezave (RF povezave) za komunikacijo. Prav tako podaja zahteve za vrednotenje skladnosti sestavnih delov z zahtevami tega evropskega standarda. Kadar sestavni deli delujejo skupaj, kar zahteva poznavanje načrtovanja sistema, ta dokument prav tako določa zahteve za sistem. Kadar sistemi za odkrivanje in javljanje požara ter alarmiranje (FDAS) uporabljajo ožičene in RF povezave, veljajo ustrezni deli EN 54 skupaj z tem dokumentom. Zahteve, ki se nanašajo na ožičene povezave, so izpodrinjene ali spremenjene z tistimi, ki so vključene v ta evropski standard. Ta dokument ne omejuje: - predvidene uporabe radijskega spektra, npr. frekvence, izhodno moč naprav; - dovoljenega največje števila sestavnih delov, ki uporabljajo RF povezave v okviru FSAD ali ene prenosne potu in/ali RF povezave; - dovoljeno največje število sestavnih delov, na katere vpliva izguba ene poti prenosa in/ali RF povezave. Te zahteve se nanašajo na nacionalne predpise in se lahko razlikujejo med državami članicami.

Introduction
The aim of this European Standard is to define additional requirements to other parts of EN 54 and tests that
allow radio fire detection systems and components complying with them to be at least efficient and stable as
wired fire detection systems and components complying with the current requirements of cable based systems
in the EN 54 standards.
System and component aspects are dealt with in this European Standard because it is difficult to describe the
components of a radio-linked system separately.
Capacity limitations with respect to the use of radio components may be specified in national technical rules or
guidelines.
Technical aspects of the assessment of frequencies, bands and channels should be considered.

1 Scope
This European Standard specifies requirements, test methods and performance criteria for components used
in fire alarms systems, installed in and around buildings, which use radio frequency links (RF links) to
communicate. It also provides requirements for the evaluation of conformity of the components to the
requirements of this European Standard.
Where components work together and this requires knowledge of the system design, this document also
specifies requirements on the system.
When the fire detection and fire alarm systems (FDAS) use wired and RF links, the relevant parts of EN 54
apply together with this document. Requirements relevant to wire links are superseded or modified by those
included in this European Standard.
This document does not restrict:
 the intended use of radio spectrum, e.g. frequency, power output of devices;
 the allowed maximum number of the components using RF links within the FDAS or one transmission
path and/or RF link;
 the allowed maximum number of the components affected by loss of one transmission path and/or RF link.
These requirements relate to national regulations and can vary from member state to member state.

4 System requirements
4.1 General
The requirements of this document shall be applied, together with requirements of the relevant part of EN 54,
where the radio-linked component has the same function as the component covered by that part and when not
otherwise specified in this European Standard.
For example, an RF linked component having the function of a heat detector shall comply with
EN 54-5 and a component having the function of a manual call point shall comply with EN 54-11.
4.2 Radio frequency links
4.2.1 Immunity to site attenuation
The manufacturer shall provide means either in the component itself or by the system configuration to ensure
that a site attenuation, which may be caused by influences for different reasons on site, may not affect the RF
link adversely in a way that communication between components is not possible. This reserve of site
attenuation shall be specified as follows:
a) at least 10 dB up to frequencies of 10 MHz;
b) for frequencies of > 10 MHz as calculated in Annex B.

SIST EN 54-25:2008
EN 54-25:2008(E)
The manufacturer shall provide the necessary documentation and/or means for the assessment which permits
the full functionality of the component to be assessed. If these means are a part of the component, the user
shall not be able to interfere with these means.
The test includes verification by an assessment and shall be carried out in accordance with 8.2.2.
4.2.2 Alarm signal integrity
The components of the system shall use a transmission protocol on the transmission path and/or the RF link
to ensure that no alarm message is lost.
The test shall be carried out in accordance with 8.2.3.
4.2.3 Identification of the RF linked component
4.2.3.1 Each RF linked component shall be identified by an individual identification code as belonging to
one specific FDAS.
4.2.3.2 The manufacturer shall provide means to ensure that a RF linked component shall not be
accepted by other FDAS.
The test shall be carried out in accordance with 8.2.4.
4.2.3.3 The manufacturer shall provide the necessary documentation and/or means for the assessment
of this requirement.

The following kind of interferences on the RF link shall be covered:
a) radio influences from own system;
b) radio influences from other users of the spectrum.
The following influences are not covered:
c) random influences as a result of electromagnetic effects, because these are covered by EMC guidelines
(see EN 50130-4);
d) deliberate attacks on the radio controlled transmission paths with the help of electromagnetic effects
(sabotage via the radio controlled route), because no special sabotage resistance is required for fire
alarm systems in the parts of EN 54.
4.2.5.2 Availability of RF link in two or more technically similar systems coming from the same
manufacturer
In the case of two or more technically similar systems coming from the same manufacturer operating within
the radio range it shall be ensured that the RF links do not mutually impede one another.
The manufacturer shall specify the means. The means shall be suitable to ensure the availability of all parts of
the system in all expected system configurations.
The test shall be carried out in accordance with 8.2.6.
