Central safety power supply systems

This European Standard specifies the general requirements for central power supply systems for an independent energy supply to essential safety equipment. This standard covers systems that are permanently connected to AC supply voltages not exceeding 1 000 V and use batteries as an alternative power source.
Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and may be suitable for energising other essential safety equipment, for example:
–   electric circuits of automatic fire extinguishing installations;
–   paging systems and signalling safety installations;
–   smoke extraction equipment;
–   carbon monoxide warning systems;
–   special safety installations related to specific buildings, e.g. high-risk areas.
Combination of the aforementioned equipment types should not be mixed together on the same central safety power supply system.
Schematic representations of typical central safety power supply equipment are depicted in Clause 4.
Power supply systems for fire alarm equipment that are covered by EN 54 are excluded.

Systèmes d'alimentation à source centrale

La présente Norme européenne définit les exigences générales relatives aux systèmes d'alimentation à source centrale des équipements spécifiques de sécurité. Elle couvre les systèmes connectés en permanence aux sources de courant alternatif dont la tension ne dépasse pas 1 000 V et qui utilisent comme source d’alimentation des batteries d'accumulateurs.
Les systèmes d'alimentation de sécurité à source centrale sont destinés à alimenter l'éclairage de sécurité en cas de défaillance de l'alimentation normale et peuvent être adaptés à l'alimentation d'autres équipements spécifiques de sécurité, par exemple:
–   circuits électriques des installations automatiques pour l'extinction des incendies;
–   systèmes de messagerie et installations de signalisation de sécurité;
–   matériel de désenfumage;
–   systèmes de détection du monoxyde de carbone;
–   installations de sécurité spécifiques à certains bâtiments, par exemple zones à haut risque.
Il convient qu'un même système d'alimentation de sécurité à source centrale n'alimente pas plusieurs des types d'équipements mentionnés ci-dessus.
Des représentations, sous forme de schémas, d’équipements typiques d'alimentation à source centrale figurent à l'Article 4.
Les systèmes d’alimentation des systèmes d’alarme incendie couverts par l’EN 54 sont exclus.

This draft European Standard is submitted to CENELEC members for CENELEC enquiry.
Deadline for CENELEC: 2013-10-25.

It has been drawn up by CLC/TC 22X.

If this draft becomes a European Standard, CENELEC members are bound to comply with the CEN/CENELEC
Internal Regulations which stipulate the conditions for giving this European Standard the status of a national
standard without any alteration.

This draft European Standard was established by CENELEC in three official versions (English, French, German).
A version in any other language made by translation under the responsibility of a CENELEC member into its own
language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
