Chapter 5 AADvance Functional Safety SystemImplementationBS EN 54 RequirementsBS EN 54 specifies the requirements for control and indicating equipment for firedetection and fire alarm systems installed in buildings. The AADvance system will becertified for use with BS EN 54 compliant systems.The systems should be integrated in accordance with BS EN 54. In particular thefollowing shall be applied. Where an alphanumeric display is used to display indications relating to differentfunctional conditions these may be displayed at the same time. However, for eachfunctional condition there shall be only one window, in which all of the fieldsrelating to that functional condition are grouped. Unless BS EN 54 section 7.12 applies, the time taken by scanning, interrogation orother processing of signals from fire detectors, in addition to that required to takethe fire alarm decision, shall not delay the indication of the fire alarm condition, orof a new zone in alarm, by more than 10 seconds. The control and indicating equipment shall enter the fire alarm condition within 10seconds of the activation of any manual call point. The audible indication shall be capable of being silenced by means of a separatemanual control at access level 1 or 2. This control shall only be used for silencingthe audible indication, and may be the same as that used for silencing in the faultwarning condition. The control and indicating equipment shall be capable of being reset from the firealarm condition. This shall only be possible by means of a separate manual controlat BS EN 54 defined access level 2. This control shall be used only for reset andmay be the same as that used for reset from the fault warning condition. Unless BS EN 54 7.11 and/or 7.12 apply, the control and indicating equipment shallaction all mandatory outputs within 3 seconds of the indication of a fire alarmcondition. Unless BS EN 54 7.11 applies, the control and indicating equipment shall action allmandatory outputs within 10 seconds of the activation of any manual call point. The control and indicating equipment shall enter the fault warning condition within100 seconds of the occurrence of the fault or the reception of a fault signal, orwithin another time as specified in BS EN 54. In the event of the loss of the main power source (as specified in EN 54-4), thecontrol and indicating equipment may have provision to recognize and indicate thefailure of the standby power source to a point where it may no longer be possibleto fulfill mandatory functions of this European Standard. In this case at least anaudible indication shall be given for a period of at least one hour. A system fault shall be audibly indicated. This indication may be capable of beingsilenced. The cabinet of the control and indicating equipment shall be of robustconstruction, consistent with the method of installation recommended in thedocumentation. It shall meet at least classification IP30 of IEC 60529:1991. All mandatory indications shall be visible at access level 1 without prior manualintervention such as the need to open a door.Document number 553630 Issue 7: February 2010 5-9
