22、Page 5EN 54-4:1997/AC:1999IntroductionThis European Standard is drafted on the basis of functions which are to be provided on all powersupply equipments. The power supply equipment may have its own cabinet, or may be housed withother equipment of the fire detection and fire alarm system, such as th

23、e control and indicatingequipment of EN 54-2. A fire detection and fire alarm system may use more than one powersupply equipment.Page 6EN 54-4:1997/AC:19991 ScopeThis European Standard specifies requirements, methods of test and performance criteria forpower supply equipment (see component L of figu

24、re 1 of EN 54-1) of fire detection and fire alarmsystems installed in buildings.NOTE: Power supply equipment with special characteristics, developed for particularapplications, is not necessarily the subject of this standard and may require further tests.2 Normative referencesThis European Standard

31、es of this European Standard the definitions given in EN 54-1 apply together withthe following:3.1.1 float voltage: The voltage which when applied to the battery will maintain the batteryin a fully charged state. The float voltage is specified by the battery manufacturer.3.1.2 final voltage: The low

32、est recommended voltage to which a battery should bedischarged. The final voltage is specified by the battery manufacturer.3.2 AbbreviationsFor the purposes of this European Standard the following abbreviations apply:p.s.e.:power supply equipment (L of figure 1 of EN 54-1)c.i.e.: control and indicat

33、ing equipment (B of figure 1 of EN 54-1)Page 8EN 54-4:1997/AC:19994 General requirements4.1 ComplianceIn order to comply with this standard the p.s.e. shall meet the requirements of clauses 4, 5, 6, 7 and8, shall be tested as described in clause 9 and shall meet the requirements of the tests.4.2 Pow

34、er sourcesThere shall be at least two power sources for the power supply of a fire detection and fire alarmsystem; the main power source and the standby power source. The main power source shall bedesigned to operate from the public electricity supply or an equivalent system.At least one standby pow

35、er source shall be a rechargeable battery.The p.s.e. shall include charging equipment to charge the battery and maintain it in a fully chargedstate.Each power source, on its own, shall be capable of operating those parts of the fire detection andfire alarm system for which it is intended. When the m

36、ain power source is available it shall be the exclusive source of power to the firedetection and fire alarm system, other than for currents associated with battery monitoring.If the main power source fails, then the p.s.e. shall be automatically switched over to a standbypower source. When the main

37、power source is restored, the p.s.e. shall be automatically switchedback.If the p.s.e. is integrated within other equipment of the fire detection and fire alarm system, thenthe switching from one power source to the other shall not cause any change in status orindications other than those relating t

38、o the power supply.If the p.s.e. is separated from other equipment of the fire detection and fire alarm system, and theswitching from one power source to the other causes an interruption in supply of power, then theduration of the interruption shall be specified in the manufacturers data.Failure of

39、one of the power sources shall not cause the failure of any other power source or thefailure of the supply of power to the system.NOTE: The compatibility of the separated p.s.e. with the other equipment, for example, the c.i.e.,will be dealt with in EN 54-13 “System Requirements“ (to be published).P

40、age 9EN 54-4:1997/AC:19995 Functions5.1 Power supply from the main power sourceWhen operated from the main power source, the p.s.e.a) shall be capable of operating in accordance with its specification given in the manufacturersdata irrespective of the condition of the standby power source. This incl

41、udes any chargecondition of the battery, or open circuit or short circuit of the connection to the battery.b) shall additionally be able to supply any required charging current for the battery or batteriesc) may allow battery charging to be limited or interrupted when the p.s.e is delivering a short
