BS EN 54 Requirements

BS EN 54-21997, A1:2006 specifies the requirements for control and
indicating equipment for fire detection and fire alarm systems installed in
buildings. The AADvance system is certified for use with BS EN 54 compliant
systems.
IMPORTANT The analogue output modules are not certified to EN 54-2.
The systems should be integrated in accordance with BS EN 54. In particular
the following shall be applied.
• Where an alphanumeric display is used to display indications relating to
different functional conditions these may be displayed at the same time.
However, for each functional condition there shall be only one window,
in which all of the fields relating to that functional condition are
grouped.
• Unless BS EN 54 section 7.11 and/or 7.12 applies, the time taken by
scanning, interrogation or other processing of signals from fire detectors,
in addition to that required to take the fire alarm decision, shall not
delay the indication of the fire alarm condition, or of a new zone in
alarm, by more than 10 seconds.
• The control and indicating equipment shall enter the fire alarm
condition within 10 seconds of the activation of any manual call point.
• The audible indication shall be capable of being silenced by means of a
separate manual control at access level 1 or 2. This control shall only be
used for silencing the audible indication, and may be the same as that
used for silencing in the fault warning condition.
• The control and indicating equipment shall be capable of being reset
from the fire alarm condition. This shall only be possible by means of a
separate manual control at BS EN 54 defined access level 2. This control
shall be used only for reset and may 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 shall action all mandatory outputs within 3 seconds of the
indication of a fire alarm condition.
• Unless BS EN 54 7.11 applies, the control and indicating equipment
shall action all mandatory outputs within 10 seconds of the activation of
any manual call point.
• The control and indicating equipment shall enter the fault warning
condition within 100 seconds of the occurrence of the fault or the
reception of a fault signal, or within 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), the control and indicating equipment may have provision to
recognize and indicate the failure of the standby power source to a point
where it may no longer be possible to fulfill mandatory functions of this
European Standard. In this case at least an audible indication shall be
given for a period of at least one hour.
