This document 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 energizing 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.  The power supply of CPS systems should be dedicated only to the essential safety equipment, and not for  other type of loads such as general purpose IT or industrial systems etc.  Combinations of the aforementioned safety equipment types are permitted together on the same central  safety power supply system providing the availability for safety equipment loads is not impaired. A fault  occurring in a circuit should not cause the interruption in any other circuit used to supply essential safety  equipment.  Schematic representations of typical central safety power supply equipment are depicted in Clause 4. 7 Power supply systems for fire alarm equipment that are covered by EN 54 (series) are excluded.
