Le présent document décrit les exigences opérationnelles et de performances, les méthodes d'essai ainsi que les résultats d'essai exigés pour les composants des dispositifs de communication avec le public (PA), des systèmes d'alarme générale en cas de situation critique (GA) et des systèmes de communication avec le public et d'alarme générale en cas de situation critique (PAGA) pour applications maritimes indiqués dans le Tableau 1 à l'appui des exigences de l'OMI pour ces systèmes, tandis qu'il appartient au fabricant de définir les composants à homologuer ensemble ou séparément pour construire un tel système. NOTE 1 Le présent document ne traite pas de l'ingénierie des systèmes pour l'installation à bord des navires ni des exigences d'installation associées. Le présent document se réfère autant que possible aux normes établies qui sont pertinentes. En l'absence de normes pertinentes ou si celles-ci ne sont pas suffisamment précises, le présent document décrit les exigences opérationnelles et de performances, ainsi que les méthodes d'essai et les résultats d'essai exigés. NOTE 2 Tous les énoncés du présent document dont la formulation est identique à celle de la circulaire MSC.808 de l'OMI ou aux exigences de la convention SOLAS sont imprimés en italique, et la résolution ainsi que les numéros d'alinéas associés sont indiqués entre parenthèses. Le Tableau 1 décrit les exigences de l'OMI applicables à chaque combinaison catégorie de navire/type de système. Le présent document indique pour chaque article et paragraphe si celui-ci s'applique aux systèmes PA, GA et/ou PAGA.

The following dates are fixed:

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
CENELEC shall not be held responsible for identifying any or all such patent rights.
The EU-Commission has received requests from stakeholders for the development of standards for public address
and general emergency alarm systems (entry A.2/1.5 in Annex A.2 of Directive 96/98/EC as amended by Commission
Directive (EU) 2015/559) and therefore requests the European standardization organisations start the development of
the respective standards.
The development of standards for public address and general emergency alarm systems is necessary because these
systems are very important for safety on board and they are exposed to specific conditions (e.g. moisture, salt) which
do not occur in other circumstances. The legislative provisions will detail the modalities for assessing that equipment.
The availability of testing standards will allow these products to be included in the scope of Directive 2014/90/EU,
which in turn will allow them to be conformity assessed by a notified body and to affix the wheel mark.
Introduction
Public address and general emergency alarm systems have the primary purpose to inform persons on board of ships
of emergency situations, and to enable the ship’s officers relay voice messages to persons on board those ships in
emergency situations.
EN 50695 has been written in pursuit of a request of the European Commission for a standard on equipment for public
address and general emergency alarm systems (PA, GA and PAGA systems). The European Commission issued this
request with the intention of taking this standard on board the Implementing Regulations belonging to the Marine
Equipment Directive (MED), with the aim to enable and require MED certification for equipment for public address and
general emergency alarm systems (PA, GA and PAGA systems). This will ensure that such equipment complies with
all applicable requirements to that equipment set by the International Maritime Organization (IMO) in SOLAS 1974 and
the LSA-code, before it is installed on board a ship.
Equipment compliant with this standard, certified according to the Marine Equipment Directive, can thus be used to
engineer and install a public address and general emergency alarm system on board a ship flying the flag of an EU
member state.
EN 50695 has been designed to make use of existing standards where possible, and specifies clarifications of
requirements in other standards, additional requirements and methods of test and required test results where
necessary to satisfy the IMO requirements.
Equipment based on EN 54 could be used as basis for PA and PAGA systems when additionally, compliant with this
document.
1 Scope
This document describes operational and performance requirements, methods of testing and required test results for
components of public address systems (PA), general emergency alarm systems (GA) and public address general
emergency alarm systems (PAGA) for marine applications as in Table 1 in support of the requirements of IMO for such
systems, while it is up to the manufacturer to define the components to be type approved together or separately, to
build up a system.
NOTE 1 This document does not include system engineering for installation on board nor installation requirements.
This document refers as much as possible to relevant established standards. Where relevant standards do not exist
or are not precise enough, this document will describe additionally own operational and performance requirements,
methods of testing and required test results.
NOTE 2 All text of this document, whose wording is identical to that of IMO circular MSC.808 or to SOLAS convention
requirements, is printed in italics, and the resolution and associated paragraph numbers are indicated in brackets.
Table 1 describes the applicable IMO requirements for each combination of ship category and type of system.

Unless this document explicitly states otherwise, each section in this document applies to all ship types.
This document indicates for each section if that section is applicable to PA, GA and/or PAGA systems.
Where this document makes sections applicable to “passenger ships”, these sections apply to both “Passenger ship
