3.2.9 EN54 Requirements
The 8000 system is certified to be used in EN 54 compliant systems.
The systems should be integrated in accordance with 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 EN 54 section 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 s.
• The control and indicating equipment shall enter the fire alarm condition within 10 s 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 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 7.11 and/or 7.12 apply, the control and indicating equipment shall action all
mandatory outputs within 3 s of the indication of a fire alarm condition
• Unless 7.11 applies, the control and indicating equipment shall action all mandatory outputs
within 10 s of the activation of any manual call point.
• The control and indicating equipment shall enter the fault warning condition within 100 s of
the occurrence of the fault or the reception of a fault signal, or within another time as
specified in this European Standard or in other parts of EN 54.
• Total loss of the power supply (option with requirements)
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 fulfil 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.
• A system fault shall be audibly indicated. This indication may be capable of being
silenced.
• The cabinet of the control and indicating equipment shall be of robust construction,
consistent with the method of installation recommended in the documentation. It
shall meet at least classification IP30 of IEC 60529:2004.
• All mandatory indications shall be visible at access level 1 without prior manual
intervention (e.g. the need to open a door).
• If the control and indicating equipment is designed to be used with a power supply
(item L of figure 1 of EN 54-1) contained in a separate cabinet, then an interface
shall be provided for at least two transmission paths to the power supply, such that
a short circuit or an interruption in one does not affect the other.
