Introduction
A voice alarm system used in a fire detection and fire alarm system provides, manually and/or automatically,
an audible fire alarm signal within the building.
Such a fire alarm voice alarm system will require voice alarm control and indicating equipment (VACIE) (see
3.1.1) to control the alarm signal(s) and the fire alarm voice message(s). The voice alarm control and
indicating equipment may be a separate unit or may be physically combined with the fire detection and fire
alarm control and indicating equipment (CIE as referenced in EN 54-2).
This part of EN 54 follows closely the format and requirements of EN 54-2 and is drafted on the basis of
mandatory functions which are to be provided on all voice alarm control and indicating equipment, and
optional functions (with requirements) which may be provided. It is intended that the options be used for
specific applications, as recommended in application guidelines.
This European Standard does not specify requirements for components of the VACIE as separate parts; they
are tested as part of the voice alarm control and indicating equipment as a whole.
Each optional function is included as a separate entity, with its own set of associated requirements, in order to
permit voice alarm control and indicating equipment with many different combinations of functions to comply
with this European Standard. Other functions associated with fire detection and fire alarm may also be
provided, even if not specified in this European Standard.
Although this European Standard does not cover emergency alarm systems for non-fire applications, it may
be used as a basis for the assessment of the control and indication equipment for such systems.
1 Scope
This European Standard specifies requirements, methods of test and performance criteria for voice alarm
control and indicating equipment for use in fire detection and fire alarm systems installed in buildings, where
the alarm signal is in the form of tone(s) or voice message(s), or both.
It also provides for the evaluation of conformity of the equipment to the requirements of this European
Standard.
NOTE The overall requirements of a voice alarm system, especially concerning audibility and intelligibility, are not
covered in this part of EN 54. The manufacturer should consider requirements of an overall system that may affect the
equipment design. Such system requirements may be specified in another part of EN 54, in national legislation, codes and
standards or in contractual documents.

of a separate manual control. In this case, this control shall be used only for reset and may be the same as
that used for reset from the fault warning condition.
7.7.2.2 Following a manual reset operation, the indication of the correct functional condition
corresponding to any received signals shall either remain or be re-established within 20 s.
7.8 Output to fire alarm devices (option with requirements)
In addition to the voice alarm outputs the VACIE may have provision for the automatic transmission of fire
alarm signals to fire alarm devices such as beacons and vibrating devices. In this case, the following shall
apply:
a) it shall be possible to de-activate the fire alarm devices at access level 2;
b) following de-activation, it shall be possible to re-activate the fire alarm devices at access level 2;
c) the fire alarm devices shall not be de-activated automatically;
d) it shall be possible to configure the VACIE at access level 3 to automatically reactivate the fire alarm
devices if an alarm is reported in an other zone.
7.9 Voice alarm condition output (option with requirements)
The VACIE may have provision for transmitting a signal that it is in the voice alarm condition. In this case, it
shall activate the output only in the voice alarm condition.
8 Fault warning condition
8.1 Reception and processing of fault signals
8.1.1 The VACIE shall enter the fault warning condition when signals are received which, after any
necessary processing, are interpreted as a fault.
8.1.2 The VACIE shall be capable of simultaneously recognizing all of the faults specified in 8.2 and, if
provided, in 8.3 unless this is prevented by:
the presence of an alarm output signal in the same voice alarm zone and/or
the disablement of the corresponding voice alarm zone or function.
8.1.3 The VACIE 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.
8.2 Indication of faults in specified functions
8.2.1 The presence of faults in specified functions shall be indicated on the VACIE without prior manual
intervention. The fault warning condition is established when the following are present:
a) a visible indication by means of a separate light emitting indicator (the general fault warning indicator),
b) a visible indication for each recognised fault as specified in 8.2.3, 8.2.4, 8.3 (if provided), 8.4 (if provided),
and 8.5 and
c) an audible indication, as specified in 8.6.
8.2.2 If the indication is on an alphanumeric display, which cannot simultaneously indicate all of the faults
because of its limited capacity, at least the following shall apply:
a) the presence of fault indications which have been suppressed shall be indicated;
b) suppressed fault indications shall be capable of being displayed by means of a manual operation at
access level 1 or 2 which interrogates only fault indications.
8.2.3 The following faults shall be indicated by means of separate light emitting indicators and/or an
alphanumeric display:
a) an indication at least common to any power supply fault resulting from:
1) a short circuit or an interruption in a transmission path to a power supply (item L of Figure 1 of
EN 54-1:1996), where the power supply is contained in a different cabinet from that of the VACIE and
2) the power supply faults as specified in EN 54-4;
b) an indication at least common to any earth fault of less than 50 kΏ which is capable of affecting a
mandatory function, and which is not otherwise indicated as a fault of a supervised function;
c) an indication of the rupture of any fuse within the VACIE, or the operation of any protective device within
the VACIE which is capable of affecting a mandatory function in the fire alarm condition;
d) an indication of any short circuit or interruption, at least common to all transmission paths between parts
of the VACIE contained in more than one cabinet, which is capable of affecting a mandatory function and
which is not otherwise indicated as a fault of a supervised function.
NOTE These indications may be suppressed during the fire alarm condition.
8.2.4 The following faults shall be indicated at least by means of the general fault warning indicator:
a) any short circuit or interruption in a voice alarm transmission path between parts of the VACIE contained
in more than one cabinet even where the fault does not affect a mandatory function;
b) any short circuit or interruption in the voice alarm transmission path to the emergency microphone
capsule, if provided;
c) any short circuit or interruption in the voice alarm transmission path between the VACIE and loudspeakers
even where the fault does not affect the operation of loudspeakers;
d) any short circuit or interruption in the transmission path between the VACIE and fire alarm devices when
used (see 7.8);
e) failure of any power amplifier.
8.3 Indication of faults related to the transmission path to the CIE (option with requirements)
The VACIE may have provision for an indication of faults related to the voice alarm transmission path to the
CIE. In this case, the short circuit or interruption of the transmission path to the CIE shall be indicated by
means of a separate light emitting indicator and/or an alphanumeric display.
8.4 Indication of faults related to voice alarm zones (option with requirements)
The VACIE may have provision for an indication of faults related to voice alarm zones. In this case the short
circuit or interruption of a voice alarm transmission path between the VACIE and the loudspeakers in that
zone shall be indicated by means of a separate light emitting indicator per zone and/or an alphanumeric
display.
8.5 System fault
A system fault is a fault as specified in 14.4 or 14.6 in the case of software controlled VACIE. A system fault
may prevent requirements of this European Standard, other than those specified below, from being fulfilled. In
the event of a system fault at least the following shall apply:
a) a system fault shall be visibly indicated by means of the general fault warning indicator and a separate
light emitting indicator on the VACIE. These indications shall not be suppressed by any other functional
condition of the VACIE and shall remain until a manua
