reflective beam smoke detectors will
be utilised.
4.9.3 The beam smoke detectors
shall project a modulated infra-red
light beam from a transmitter unit to a
receiver unit. The received signal shall
be analysed and, in the event of smoke
being present for a pre-determined
period, an alarm condition is activated.
4.9.4 The detectors shall be capable
of providing cover in open areas up to
100m in length and up to 14m wide,
giving an effective protection area of
up to 1400sq m.
4.9.5 The fire alarm output of the
detectors shall be activated in the
event of smoke reducing the signal
strength between 40% and 90% for a
period of approximately 5 seconds.
4.9.6 In the event of a power
failure at the transmitter unit or if the
transmitted signal is reduced by more
than 90% for a period in excess of 1
second, then a fault alarm condition
shall be indicated. This condition shall
inhibit the fire alarm until the signal
is restored.
4.9.7 The receiver unit of the

performing an automatic reset,
approximately 5 seconds after a
fault is indicated, if the fault is no
longer present.
4.9.8 The detectors shall include

strength caused by component ageing
or build-up of dirt on the optical
surfaces of the transmitter and receiver
unit lenses.

shall meet the requirements of
EN54-12.
4.9.10 The beam smoke detectors
shall be approved and listed by the

4.9.12 The preferred beam type
smoke detector would have an integral
auto aligning feature, designed to
realign the unit with its reflector if
due to building movements the two
components are misaligned. The
feature is also an aid to the initial
installation and commissioning
4.9.13 For Atria and other similar
roof spaces Open Area Smoke
Detection Imaging is the preferred
detection. This overcomes the
weaknesses of some beam detectors
due to its aesthetics and multi-emitter
capability, providing 3D coverage
of the area.
A system can consist of up to seven
Emitters and one Imager placed on
opposite walls, roughly aligned with
one another. Emitters can be batterypowered or wired and are placed at
different heights, adjusting easily to
modern design of atria. Three Emitters
will cover an area of up to 600m2 and
five Emitters to 2000m2, all using
just a single 80-degree Imager. In
addition, Open Area Smoke Detection
Imaging offers many advantages over
traditional beam smoke detectors,
the primary one being the use of dual
light frequencies. Ultraviolet (UV) and
infrared (IR) wavelengths assist in the
identification of real smoke compared
to larger objects such as insects and
dust, thus reducing false alarms.
Furthermore, Open Area Smoke
Detection Imaging is equipped with
a CMOS imaging chip with many
pixels rather than a single photodiode. This concept allows the Imager
to provide simple alignment as well
as excellent tolerance to building
movement and vibration, without
the use of moving parts.
Open Area Smoke Detection Imaging
provides, new levels in stability and
sensitivity while providing greater
immunity to high-level lighting
variability, allowing it to provide extra
stability in sunlit areas such as atria.
The Open Area Smoke Detection
Imaging should be integrated with
the building fire alarm system.

4.10.10Where there is a requirement
for gas detection in addition to
aspirating smoke detection, it shall
be possible to provide this through
the same system of pipe work as that
used for the fire detection. The system
should be capable of detecting a
range of flammable, toxic and oxygen
gas hazards and provide a greater
area of coverage than fixed point gas
detection systems. The system would
be restricted for use in indoor in non
‘Hazardous’ classified areas only.

sensor cartridge containing 1 or 2
gas sensors using industry proven
electrochemical & catalytic sensors.

so as to limit the numbers of devices
that may become inoperative due to
a cable fault. Short circuit isolators
should be installed into fire alarm

Overview
The Harmonisation of Standards for
the design and manufacture of Fire
Alarm and Detection Equipment.
Introduction
In 2013, after years of consultation,
the EU Commission’s proposal for a
new Construction Products Regulation
finally became effective. Unlike
the Directive, which preceded the
Regulation, member states cannot be
selective as to which parts they adhere
to. Proof of compliance with this
regulation in respect of manufactured
product is the CE marking.
Products for use as Fire Detection and
Fire alarm systems are regulated by
a set of standards referenced EN54.
Standards that are in the process of
being written are prefixed with the
letters pr. Once written and agreed
it becomes a harmonised standard,
which under the EU Regulation applies
in all EU member states and therefore
has the status of being a national
standard within that country. Annex ZA
of each standard deals with the clauses
of the standard in respect of their
compliance with the mandate of the EU
construction products directive, (now
regulation).
All products built to EN54 standards
are tested by independent third party
organisations, of which there are
several, across various member state
countries. The testing of products is
vigorous and comprehensive as will
be seen from the individual standards.
Approval whilst being mandatory
within the EU also proves reliability
and longevity as well as sensitivity
which together are some of the
most essential components of both
life safety and property protection
systems.
The aim of the following document
is to provide an overview of each of
the current harmonised standards,
whilst not negating the need to
consult, at times, both the full EN54
standard document together with other
supporting documents, such as the
ISO/IEC 6000 series of publications.
Foreword
These standards replace all previous
versions and have the status of being
national standards in all EU member
states and therefore support the
essential requirements of the EU
regulations.
All devices should be clearly labelled
with the manufacturers name or logo,
part number, electrical connection
detail and any further information
which provides a means to identify the
place and date of manufacture, batch
and software versions. For detachable
units both parts should be labelled.
All labelling should use symbols or
abbreviations which are in common
use, otherwise such information
should be explained in supporting
documentation. The labelling should
be permanent and clearly visible at
all times.
section two
an introduction to the suite of EN54 standards
introduction
Documentation shall be provided,
prior to testing, which provides an
aid to both installer, maintainer and
user, giving a general description,
detail of the device and which will
support any compatibility assessment
to be undertaken, as detailed in EN541, including power requirements,
input/output ratings, transmission
paths, battery capacities, current
and internal resistance levels.
Information relative to the connecting
cables, environmental protection,
and mounting and connection
detail together with operating and
maintenance instruction shall also be
provided.
Additional testing for voice sounders,
to verify that the output level of the
broadcast message in relation to that
of the alert signal is sufficient. To verify
the timing between the alert signal, the
silence before and after the message
and before the next alert signal, is
within the limits set in table C1 of
appendix C of EN54-3.
Durability, to show that the sound level
does not change significantly after
prolonged operation.
If on site adjustment of the device’s
response type is provided, the data
shall clearly indicate the classification,
means of adjustment or programming
instructions.

functional tests are to show the call
point’s ability to withstand small forces
when applied to the frangible element
and to operate correctly and only when
an appropriate force is applied, all
without damage to the test and reset
functions which are also tested.
(EN54-11)
Configuration data relevant to the
compliance with a standard shall be
stored in non-volatile memory and
access shall be password protected or
by use of a special tool and shall only
be possible when the device is taken
out of normal service.
Dry heat (operational), to establish the
equipment functions correctly at high
ambient temperatures for short periods

introduction
Foreword
This standard replaces all previous
versions and has the status of being
a national standard in all EU member
states and therefore supports the
essential requirements of the EU
directive(s).
Introduction
The EN54 standard, part 1 explains
the use of each part of the EN54 suite
of standards. The standards apply to
systems used for the early detection of
fires in buildings, including providing
warnings both locally and remote and
operating other fire precautions, such as
water or gaseous suppression systems.
Consideration should be given if these
standards are used for systems installed
in other than building applications, as to
their suitability.
Each standard covers the requirements,
test and performance criteria, for
measuring the reliability of the system
component parts which together form
the complete system. The tests are
designed to prove their performance
under varying conditions which they
are likely to be subjected to during their
lifetime.
Some standards listed below are
published as harmonised standards.
However some are relatively new
and others are still in the process of
preparation and some may not be EN54
standards.
CEN/TS 54-14 is an existing design
standard which is currently being
updated and will be an option in
countries that do not have their own
standards. An alternative published
standard is ISO 7240-14 which offers
similar design guidance. In countries
that have their own national standard,
e.g. in the UK BS5839, these will
undoubtedly be the adopted standards.
Parts 16, 24 and 32 refer to voice alarm
equipment which may form a separate
and sub system to the fire alarm and
detection system, but which when
interconnected will effectively work as a
complete system.
EN54-22 and 28 are draft standards
covering line type heat detectors and
resettable types.
Part 23 covers visual alarm devices
which may be installed to compliment
audible devices in noisy areas or to
provide a warning to hearing impaired
personnel.
Part 26, is in development and will cover
point detectors using carbon monoxide
sensors.
Part 27, is still in preparation and will
detail the requirements for mounting
smoke detectors into ducts.
Parts 29, 30 and 31 are all at varying
stages of preparation and will, in
time, cover multi sensor detection
devices which may detect different fire
section two

introduction
phenomena providing a wider spectrum
of detection capability than a standard
single channel device. The various
detection channels of these devices can
be combined in software to provide
either more resilience or increased
sensitivity dependent upon the risk and
environment. Currently ISO 7240- 8
and 15 and CEA 4021 are all published
documents covering some types of
multi sensors.
Part 32- is at some stage of
preparation and will form a guide to
design, installation, commissioning,
maintenance and use of voice alarm
systems
Part 13 of the standard assesses the
compatibility of components, which
although individually approved to the
relevant standard, have been assessed
when working together as a system.
This standard, whilst being the only
published standard is not harmonised
and is therefore not enforced under the
Construction Product Regulation. It does
however offer sound practical guidance
to building networked systems.
Clause 4 of this Standard specifies both
input and output functions associated
with the fire detection and fire alarm
system. Table A.1 (below), gives
examples of products that fulfil these
functions and references these to the
applicable published standards
Annexes to EN54-1
A- Functions, examples and relevant
standards, Clause 4 of this European
Standard specifies functions and
equipment of the fire detection and

systems. Table A.1 in Annex A gives
examples of products that carry out
the specified functions and gives
information on relevant published
standards applicable to these products
and systems.

Part 2 control and indicating equipment
Introduction
The standard covers both mandatory
and optional functionality with
regards to the system control and
indicator equipment. The “optional
functions” allows for specific functions
associated with requirements which
may not be standard but still allows
the products to comply. The options
covered in annex B are those already
used by some member states and
have therefore been included in this
standard and may also form part of
their local national standard.
Requirements
The control and indicating equipment
shall be capable of being in, and also
displaying indication appropriate to,
Fire, Fault, disablement, and where
provided, test. The rules governing
alphanumeric displays are also listed.
An indication of external power
shall be provided. Any other kind
of indication may be displayed,
however all indications must be
clear and unambiguous.
Audible indication, indicating a change
of state shall be provided within the
control and indicating equipment
and shall be capable of being silenced,
but not automatically. The audible
alarm should resound for each
subsequent event.
A reset function shall be provided
and be used for both fire and fault,
with the current status of the system,
including points not reset being
displayed within 20 seconds.
Output of the fire alarm condition may
be signalled to numerous devices,
including audible alarms, visual
alarms, transmission equipment and
other fire protection systems, with at
least one output being mandatory.
Time constraints are detailed in
this section, being 10 seconds, if no
delays are programmed. Delays and
coincidence are recognised as being
acceptable in some cases with delay
timers being programmable up to a
maximum of 10 mins. The rules relating
to these functions are detailed within
the standard. The equipment may
include provision to record the number
of fire alarm events.
Fault recognition and indication is
covered in respect of the various
categories of fault which could occur.
These include faults within and
external to the control and indication
equipment. These are prioritised
into three groups, faults in specified
functions, power loss and system
faults. The implications of each can
be quite different. Faults shall be
processed and their status indicated
within 100 secs.
section two
an introduction to the suite of EN54 standards
control and indicating equipment
In the event of a mains power loss,
the equipment shall have the ability
to recognise if the standby supply
is capable of providing at least the
mandatory system function, otherwise
an audible indication shall be sounded
for a period of at least 1 hour.
Disablements may be applied to
inputs and outputs, such as zones,
audible and visual devices and signal
transmission paths. Such disablement
should only affect those linked
indications and outputs and not be
global. Indications of disablements
shall be provided both generally and
for specific disablements.
Indication of a Test Condition shall
be displayed whenever any part of
the system is under test. Those parts
of the system under test must be
clearly displayed and all mandatory
indications from those parts of the
system not under test will still be
provided. Tests must be started and
ended manually. Outputs from those
zones under test will not be triggered
by the test.
The Input/output Interface is an
approved method of communicating
between the main control and indicator
panel and a sub panel capable of
performing functions associated
with the cause and effect, such as
operating a fire protection system or
communicating with the fire brigade.
The sub panel is not a part of the main
control and indicator panel under
this standard; however the minimum
functional requirements regarding
the interface are clearly detailed.
Where the sub panel is a fire brigade
panel and because requirements vary
from country to country, the specified
interface functions negate the need
for the panel specification to be
harmonised under this standard. Most
panels will be approved locally.
Design Requirements for the control
and indicator panel are listed in clause
12 of the standard. Not all panel
functionality can be tested therefore
manufacturers are required to confirm
compliance in accordance with the
standard by way of documentation.
Both electrical and mechanical details
are included in the standard as is the
integrity of its transmission paths, the
accessibility of indicators and controls,
the specification for indicator lights,
including colours, alphanumeric
displays, and audible indications.
The panel’s software and software
processing methods together with the
means of storing both programmes
and data are also detailed.
page 77
section two
an introduction to the suite of EN54 standards
control and indicating equipment
The panel will be clearly labelled,
including the ref to the standard, the
manufacturers logo and model number.
Testing of the main control and
indicator panel is carried out in a
test environment with a specimen
configuration loaded into the panel.
The test objectives are to prove the
operation of the equipment and to
enable this; a test schedule is drawn
up prior to testing. Testing will prove
the fire alarm, fault and disabled
conditions. Environmental tests
are carried out in accordance with
table 1, below.

section two
an introduction to the suite of EN54 standards
part 3 fire alarm devices - sounders
Introduction
This standard covers the requirements
for the construction and performance
of sounders and their performance
under climatic, mechanical and
electrical interference conditions.
Sounders are classified as indoor (A)
and outdoor (B). In fire detection and
fire alarm systems, voice sounders are
also used for warning the occupants
of a building of the outbreak of fire,
using a combination of signal and
voice message(s).The requirements,
test methods and performance criteria
specified in this standard for sounders
are also applicable to voice sounders.
Additional requirements specific to
voice sounders are incorporated in
Annex C.
Requirements
The sounder may produce different
sound levels under different
conditions, e.g., when operating
on different voltage ranges or with
different sound patterns. When
appropriate the sound level of each
unit may be measured for each sound
pattern when tested. Alternatively the
sounder will be tested using an output
deemed to consume max current and
produce the maximum sound output.
The sounder shall produce A-weighted
sound levels of at least 65 dB in one
direction and not exceeding 120 dB in
any direction.
(A- weighted sound level sound
pressure expressed in dB,
characteristics are given in IEC 60651).
Sounders can produce different
frequencies and sound patterns and,
therefore, this standard does not
specify a minimum and maximum
for either. These may also vary from
country to country; therefore local
standards need to be consulted. Access
to the device shall be restricted by the
use of special screws or tools and it
should not be possible to change the
manufacturer’s settings without use of
the same or by breaking a seal.
If on site adjustment of the device
settings is provided, then the factory
setting, which complies with this
standard, should be clearly displayed
for each and should only be accessible
to change with a password or special
tool.
Sounders shall be rated for a minimum
of 100 hours which will not affect their
ability to cycle on and off as required
as part of the compliance testing. This
requirement does not apply to the
capacity of any integral batteries used
as a means of providing local standby
power. The capacity and charging
requirements of such batteries should
meet the requirement of the system..
The degree of protection provided by
the enclosure of fire alarm sounders
shall be in accordance with EN60529,
page 81
section two
an introduction to the suite of EN54 standards
fire alarm devices - sounders
IP21 for type A and IP33 for type B.
The attached labelling, will provide,
reference to this standard, type A or B.
Voice Sounders are audible devices for
generating and broadcasting recorded
voice messages. The voice sounder
shall meet all of the requirements
applicable to audible fire alarm
devices. To prevent acoustic interaction
between adjacent voice sounders the
provision for synchronising the alert
signal and message sequence with
that of other devices of the same type
may be necessary. In this case, the
requirements of the test described in
appendix C shall be met.
Tests, are carried out to prove
the sound levels specified by the
manufacturer are achievable within
the specified voltage range and do
not deviate by more than 6dB for each
direction. The maximum sound level
must provide an output greater than
65dB (A) in at least one direction,
and not exceed 120dB (A) in any
direction, at 1 metre. Sound levels are
required to be at the specified level
for each of the angles specified by the
manufacturer, through a semi -circular
arc in front of the device).

part 4 power supply equipment
Introduction
Functionality
This standard covers the requirements,
test procedures and performance of
power supplies used with fire alarm
and detection systems in buildings,
both internal and external to the
control and indicating equipment.
The power supply shall be capable of
delivering full power to the system
irrespective of the standby battery
condition, including when recharging
a discharged standby battery. The
standby battery charging current can
be reduced when the power supply is
required to supply maximum current to
the system. The standby battery should
also be capable of supplying the
systems demands when the incoming
mains supply is disconnected. The
power supply shall be fully monitored,
including incoming mains, battery
supply, and battery high resistance.
The power supply shall signal a fault
condition within 30 minutes of the
fault occurrence. If the power supply
unit is an integral part of the control
and indicating equipment such faults
shall be signalled in accordance with
EN54-2.
General requirements
The requirements for meeting this
standard are detailed in clauses 4-8
and testing is as detailed in clause 9
of this standard. The power supply
unit will operate from an incoming
mains supply and incorporate at least
one rechargeable standby battery. The
unit will be capable of maintaining a
fully charged battery. Each source of
power shall be capable of supplying
the specified output or for an integral
power supply, the equipment into
which it is integrated.
The incoming mains supply should be
solely for the fire detection and alarm
system and its standby batteries. The
battery should automatically supply
the system in the event of an incoming
power failure and revert to standby
when the supply is restored. Failure of
an integrated power supply incoming
mains shall be transparent other
than to operate any power warning
indicators. Any known interruptions
during changeover of power source
shall be detailed by the manufacturer.
Failure of one power source shall not
render the unit inoperative such that
no power is delivered to the system.
The design, electrical and mechanical,
shall be in accordance with section 6
of the standard. If the power supply
is designed for use with the control
and indicating equipment but external
to, then duplicate connections should
be made ensuring that a single short
circuit cannot result in a loss of power.
The standby battery will be suitably
labelled indicating its age and type and
if integral to other components of the
fire alarm and detection system, shall
be of the sealed type. The batteries
output voltage should be monitored
and outputs turned off if that voltage
section two
an introduction to the suite of EN54 standards
power supply equipment
falls below the specified level.
The battery charger will charge the
battery automatically and when
discharged to its final voltage be
recharged to 80% of its capacity within
48 hours. The charger shall be designed
and operate within the battery
manufacturers temperature limits.
Other than for monitoring purposes the
battery shall not discharge through the
charger,
when a potential difference exists.
If required to operate during the testing
the power supply equipment shall be
connected to both mains and a suitable
battery. The output shall be connected
to suitable cable and tested under a
full load. Fully functional tests are as
detailed in section 9 and carried out
in accordance with table 1. However
the procedure and requirements do
vary between integrating and nonintegrating power supply equipment.

environment into which the detector is
placed and which exists for most of the
time in a none fire situation as detailed
in table 1.Maximum application
temperature is that which the detector
may be subjected to for short periods
of time, in a non-fire situation as
detailed in table 1.
Static response temperature is
that at which the detector would
be in an alarm state if subjected
to a vanishingly small rate of rise
temperature, typically 0.2K min -1

Detectors incorporating a rate of rise
characteristic will meet the response
requirements shown in table 4, even
when installed where temperatures
are significantly lower than the typical
application temperature.
Individual alarm indication shall be
provided for class A1, A2, B, C or D
detectors via a red visual indicator

For detachable detectors the indicator
may be in the head or the base and
should be visible at a distance of 6
metres directly below the detector in
ambient light levels of up to 500 lux.
Classes E, F or G detectors shall
contain either an integral red indicator
or some other means of indicating its
alarm state.

shall be provided by which removal
of the detector from its base
without some form of indication
is not possible.
The manufacturer’s settings should not
be accessible to change without the
need for a password, special tool or
by the breaking or removal of a seal.
If on site adjustment of the detectors
response type is provided, then
the factory setting, which complies
with this standard, should be clearly
displayed for each detector and should
only be accessible to change with a
password or special tool or by the
removal of the detector from its base.
Any settings which are not compliant
with this standard shall only be
accessible by the same means and
it should be clearly displayed, either
on the detector or in data format, the
detector does not comply with this
standard. The adjustments may be
carried out either at the detector or via
the control and indicator equipment.
Configuration data relevant to the
compliance with a standard shall be
stored in non-volatile memory and
access shall be password protected or
by use of a special tool and shall only
be possible when the device is taken
out of normal service.
section two
an introduction to the suite of EN54 standards
heat detectors - point detectors
Detectors are subjected to the
following Test Schedules.
Directional dependence: to prove that
performance is not dependent upon a
specific airflow
Static response temperature: to

application temperature: to prove the
detectors response, (table 1) to a range
of rate of rise air temperatures. The
response times should lie between the
upper and lower levels shown in table
4, relative to its class.
Variation in supply parameters:
to prove that within the detectors
specified voltage range the response
times are reasonably constant
Reproducibity: to show that response
times are within the specified limits
and for resettable detectors that
the response times do not vary
significantly during repeat testing.
Response times shall be as detailed in
table 4, between the upper and lower
levels.
Cold (operational): to prove the
detector operates correctly in low
temperature environments. The

subjected to a rise in temperature of 3
Kmin-1 shall not be less than 7min 13s.
At a temperature rise of 20 Kmin-1 the
response time shall not be less than
1min. For non- resettable detectors the
response times shall be those shown
in table 4.

part 7 smoke detectors
Scope, the standard specifies the
requirements, test methods and
performance criteria for point type
smoke detectors, both optical
and ionisation, including smoke
detectors with more than one
sensor. Ionisation detectors are
not permitted in certain countries
therefore local codes should be
consulted.
Requirements
Compliance, for the detector to meet
the requirements of this clause shall
be verified by visual inspection or
engineering assessment, tested
as described in clause 5 and, for
detectors with more than one smoke
sensor, shall meet the requirements
of the tests detailed in Annex N.
Individual alarm indication shall be
provided via a red visual indicator
which shall be extinguished
when the detector is reset. Where
conditions other than fire are
indicated these shall be clearly
distinguishable other than when
the detector is in service mode. For
detachable detectors the indicator
may be in the head or the base and
should be visible at a distance of 6
metres directly below the detector
in ambient light levels of up to 500
lux. Where there is a connection to
remote indicators, control relays etc.,
failures of these connections shall
not prevent the correct operation of
the detector.
Monitoring of detachable detectors
shall be provided by which removal
of the detector from its base without
some form of indication is not
possible.
The manufacturer’s settings should
not be accessible to change without
the need for a password, special
tool or by the breaking or removal
of a seal.
If on site adjustment of the detectors
response type is provided, then
the factory setting, which complies
with this standard, should be clearly
displayed for each detector and
should only be accessible to change
with a password or special tool or
by the removal of the detector from
its base.
Any settings which are not compliant
with this standard shall only be
accessible by the same means and
it should be clearly displayed, either
section two
an introduction to the suite of EN54 standards
smoke detectors
on the detector or in data format,
the detector does not comply with
this standard. The adjustments may
be carried out either at the detector
or via the control and indicator
equipment.
The detector shall be designed to
restrict the access of insects into its
sensitive parts without restricting
smoke entry. In order to achieve this
it may be necessary to take other
precautions against false alarms due
to the entry of small insects.
The provision of “drift
compensation” to counter the
effects of a build-up of dirt in the
detector shall not significantly
reduce the detector’s sensitivity to
slowly developing fires. To verify
this, an assessment of the detector’s
response to slow increases in smoke
density shall be made. The detector
shall meet the requirements of
clause 4.8 if its response times falls
within those specified.
Testing a detectors response with
very slow increases in smoke
density is impractical and therefore
assessment is made of the detectors
response by a combination of
test and simulations together
with analysis of the software. The
detectors performance is measured
against formulae designed to
confirm a response within 100
seconds when the increase in smoke
density is greater than one fourth
of the detector threshold value
multiplied by 1.6. This ensures the
detectors response value does not
increase by more than a factor of 1.6
before an alarm condition is reached.
A detectors response should fall
between a maximum sensitivity
of 1.5% and a minimum of 6%
obscuration per metre when tested.

part 10 flame detectors
Scope
This European Standard specifies
the requirements, test methods
and performance criteria for pointtype, resettable flame detectors that
operate using radiation from a flame
for use in fire detection systems.
Requirements
Compliance is for the detector to
be verified by visual inspection
or engineering assessment and
successfully tested as described in
clause 5. Detectors will be classified,
when responding to fires within 30
secs as: Class 1, up to 25metres,
Class, 2 up to 17 metres or Class 3,
up to 12 metres. Below 12metres
detectors will not be classified.
Individual alarm indication shall be
provided via a red visual indicator
which shall be extinguished when the
detector is reset. Where conditions
other than fire are indicated these
shall be clearly distinguishable other
than when the detector is in service
mode. For detachable detectors the
indicator may be in the head or the
base. Where there is a connection
to remote indicators, control relays
etc., failures of these connections
shall not prevent the correct
operation of the detector.
Monitoring of detachable detectors
shall be provided by which removal
of the detector from its base without
some form of indication is not
possible.
The manufacturer’s settings should
not be accessible to change without
the need for a password, special tool
or by the breaking or removal of a
seal and for each setting. For those
settings which the manufacturer
claims compliance with this
standard, each shall have achieved
a classification corresponding to
that marked on the detector for that
setting;
If on site adjustment of the detectors
response type is provided, then
the factory setting, which complies
with this standard, should be clearly
displayed for each detector and
page 103
section two
an introduction to the suite of EN54 standards
flame detectors
should only be accessible to change
with a password or special tool or
by the removal of the detector from
its base.
Any settings which are not compliant
with this standard shall only be
accessible by the same means and
it should be clearly displayed, either
on the detector or in data format,
the detector does not comply with
this standard. The adjustments may
be carried out either at the detector
or via the control and indicator
equipment.
Technical data regarding both
installation and maintenance
should be provided with each
detector or in the case of supporting
documentation, document
references should be provided. If
on site adjustment of the detectors
response type is provided, the
data shall clearly indicate the
classification, means of adjustment
or programming instructions.
For detectors which are software
control controlled then the
documentation, design, and storage
of programs and data will meet the
requirements of 4.9.2, 4.9.3 and 4.9.4.
The Principle of testing is to
measure the response point when
exposing the detector to radiation
from a suitable flame source and
establishing the maximum distance
at which the detector will reliably
enter the alarm condition within a
time of 30 s. The test apparatus shall
be as described in annex A, B and C.
When testing, the radiation source
is modulated in accordance with
the manufacturer’s specification.
Tests are conducted using methane,
n-heptane, and methylated spirit.

devices, those fitted with electronic
components (e.g. resistors, diodes)
and addressable units. This Standard
does not cover manual call points
for use as intrinsically safe or for
in hazardous conditions, where
such applications require further
requirements or tests. The Colours
of various parts of the call point
shall be in accordance with 4.7.2.3
Compliance is for the manual call
point which shall be verified by
visual inspection or engineering
assessment and successfully tested
as described in clause 5.
Requirements
Each manual call point should
be clearly labelled providing
information regarding the relevant
standard, type, and whether indoor
or outdoor version.
The normal condition of the call
point shall be recognizable by the
appearance of the operating face as
detailed in 4.7.which shall be flat and
shall not be broken, deformed or
displaced?
Change from the normal to the alarm
condition, will be by the following
methods
For type A manual call points,
breaking and/or displacing the
frangible element together with
changing the appearance of the
operating face.
For type B manual call points: as
above plus manually activating the
operating element.
It shall be possible to see that the
operating element is in the activated
position but not possible to activate
it without breaking or displacing the
frangible element [see 4.3.2 b)] or
without the use of a special tool
(see 4.6).
A transparent flap may be fitted
over the call point to protect against
accidental operation of a type A call
point. If Individual alarm indication

is provided it shall be positioned
on the front of the call point, be red
and shall be extinguished when the
call point is reset. It shall be visible
from a distance of 2 m directly in
front of the manual call point in an
ambient light intensity up to 500 lx.
Where conditions other than fire
are indicated these shall be clearly
distinguishable other than when the
call point is in service mode. The
call point shall be marked with the
appropriate symbols as detailed in
paragraph 4.7.3.
The manual call point shall be reset
after operation as follows:
a) for non-resettable frangible
elements, by inserting a new
element;
b) for resettable frangible elements,
by resetting the frangible element.
Furthermore for type B manual call
points, it shall only be possible to
return it to its normal condition by
means of a special tool.
The manual call point shall
incorporate a test facility, which will
require a special tool to simulate
an alarm condition by activating
the operating element, allowing the
manual call point to be reset without
breaking the frangible element.
Operating the frangible element shall
not cause injury to the operator.
For type B manual call points the
actuation force of the operating
element shall meet the requirements
of EN 894-3:2000.
For manual call points which are
software control controlled then the
documentation, design, and storage
of programs and data will meet the
requirements of 4.8.2, 4.8.3 and 4.8.4.
The alarm signal shall respond to the
required test, indicated at the supply
and monitoring equipment (see
5.1.2) within 10 s after the operating
element has been activated.

Scope
This document specifies the
requirements for the compatibility
and connectability of system
components that comply with the
requirements of EN 54 or with
their specification in the absence
of an EN 54 standard and includes
system requirements only when
these are necessary for compatibility
assessment. It also specifies
requirements for the integrity of the
fire detection and fire alarm system
when connected to other systems.
Requirements
Compliance with this standard
requires the system design and
compatibility of its components
to meet the requirements of this
clause. This shall be verified by
assessment (5.1) with regard to the
documentation (4.7), and shall be
successfully tested (if necessary)
as described in 5.2 to 5.5. System
requirements can also be stated
in national application guidelines /
codes of practice. Suppliers of
components must ensure that
they meet the requirements of this
document and the relevant part
of EN 54 and also the requirements
of the application guidelines of the
countries where the components
are intended to be used.
Networked systems
A fault in a single fire alarm
control panel shall not affect other
control units. A single fault on a
transmission path connecting control
panels shall not adversely affect the
functionality of the network. Where
more than a single fault results in
control panels being disconnected
it shall be clearly displayed which
panels are affected. All faults shall be
indicated. Where there is justification,
e.g. a high life risk the standard
suggests that at each control panel
there be a facility to communicate
with the fire brigade, should 2
simultaneous transmission faults
occur, disconnecting a panel
from the network and the main
control panel.
A fire alarm condition shall be
indicated on the main control panel

of the system.
At the main control panel it shall be
possible to identify the panel from
which the signal originated.
Assessment methods and tests
At the main panel, it may be possible
to operate controls which are found
on the individual panels, but only
with the same affects. Any software
that is used for networking shall
conform to EN 54-2:1997, Clause 13.
Compatibility can be achieved
if essential components (type 1)
operate within the specified limits in
the relevant part of EN54, whereas
essential components not covered by
an EN54 standard shall conform to
EN54-1, clause 4 and meet the EMC
immunity requirements of EN501304. For a non-essential component
(type 2), such as a printer, to be

part 16 voice alarm control and indicating equipment
Introduction
This standard covers the
requirements for the construction
and performance for voice alarm
control and indicating equipment
for use in fire detection and fire
alarm systems where the audible
signal is in the form of tone(s) and/
or voice message(s).Those parts of
the system concerning audibility
and intelligibility, are not covered in
this standard. Consideration should
be given to the requirements of an
overall system that may affect the
design and which may be specified
in another part of EN 54, in national
legislation, codes and standards or in
contractual documents.
in structure to part 2 stipulates those
functions that are mandatory, as well
as those which are optional. As in
part 2 the optional functions may be
specific to certain applications
When the systems are truly
integrated they may share common
indications, manual controls and
outputs (see Annex F); however a
single fault affecting the control and
indicator panel shall not affect the
mandatory functions of the voice
alarm system. The indications and
manual control(s) of the voice alarm
condition shall be clearly identifiable.
Requirements
The system power supply equipment
may be common to both systems but
must comply with the requirements
of EN 54-4.
A voice alarm system, when forming
part of the fire detection and fire
alarm system provides an audible
fire alarm signal. Such a system
will require voice alarm control and
indication in order to react to an
incoming alarm and subsequently
generate and broadcast a message.
The two systems may share an
integrated form of control or be
separate. This standard being similar
The voice alarm control and
indicator shall be capable of clearly
displaying the following, a quiescent
condition; voice alarm condition;
fault warning condition and a
disablement condition .The control
shall be capable of displaying, on
different alarm zones at the same
time, a voice alarm condition; fault
warning condition and a disablement
condition.
section two
an introduction to the suite of EN54 standards
voice alarm control and indicating equipment
Where specified, all mandatory
indications shall be clearly identified
and where alpha numeric displays
provide additional information for
different functional conditions these
may be displayed at the same time.
Information should be grouped
and separated for each condition.
A separate power on indicator shall
be provided on each enclosure,
where they exist. Where further
indication is provided it shall be
distinguishable and not override
the primary indicators. A system
normal display may be provided but
must not conflict with the above.
The voice alarm control shall be
capable of receiving and processing
alarm signals and generating the
appropriate voice alarm outputs
within 3s or on the expiry of any
delay period.
Annex E provides additional
information concerning the interface
between the voice alarm and the fire
alarm controllers. The voice alarm
control shall provide a fault warning
within 100 s of the occurrence of a
fault, unless specified differently in
this European Standard or in other
parts of EN 54. The voice alarm
control may have provision for at
least one spare power amplifier
which should replace the faulty
equipment within 10 secs of the fault
being detected. The spare should be
supervised when not in use.
A common fault warning shall be
provided if there is a condition
relating to any short circuit or
interruption in a voice alarm
transmission path, including the
microphone and loudspeakers,
even where the fault does not affect
the operation of loudspeakers; and
to any fire alarm devices when
used, and the failure of any power
amplifier.
The mandatory indications and/or
outputs shall not be corrupted by
multiple alarm signals when received
simultaneously, either automatically
or manually. Where the voice and fire
alarm systems are separate, failure
of the transmission path between
the two shall not result in any loss
of control or change of state of the
voice alarm, without indication being
provided.
The audible alarm (message) may
be delayed, up to a maximum of
10 minutes but may be over-ridden
page 121
section two
an introduction to the suite of EN54 standards
voice alarm control and indicating equipment
manually. Delays can be turned on/
off manually or automatically, with
the applicable level of access and
a separate and discreet indicator
or display shall be visible when
an alarm occurs when the delay
is turned on. The display will be
cancelled when the alarm message
is broadcast. The system can be
configured for phased warning
broadcasts, which can be switched
on and off with the applicable level
of access.
Where the voice alarm condition has
been triggered from the fire alarm
control, the message broadcast
may be silenced and reset from
the same control panel; incomplete
messages will be completed before
being silenced. The silence function
should be reversible and messages
rebroadcast when required. Any
parts of the system which
remain in alarm after rest shall be
redisplayed within 20 secs.
In addition to the voice alarm outputs
the control may have provision
for the automatic transmission of
fire signals to other devices such
as beacons and tactile devices. It
shall be possible to deactivate and
reactivate these with the appropriate
level of access, but not automatically.
The alarm broadcast may be
manually activated, zone by zone,
or in groups of zones with the
appropriate access level. Manual
activation will activate all mandatory
inputs and outputs. Indication that a
voice alarm condition exits in each
zone shall be provided and may be
via a led and/or LCD display. Fault
and disablement conditions can be
displayed in similar fashion.
The voice alarm control may be
interfaced to external control
device(s) such as those required by
local regulations; such interfaces
shall provide only limited access
and the mandatory functions of
the voice alarm control shall not
be overridden. Any faults in the
transmission path between the two
shall not prevent the operation of
the mandatory functions, and shall
display a warning if such a fault
occurs.
The external control devices should
comply with available local codes,
European Standards or national
standards.
section two
an introduction to the suite of EN54 standards
voice alarm control and indicating equipment
The voice alarm control may contain
emergency microphones which
shall have priority over all inputs,
including pre-recorded messages.
Access will be by an appropriate
level. Where a pre-alarm tone
precedes the activation of the
microphone an adjacent indicator
will display when the microphone
becomes active.
When the emergency microphone
is in use any audible indication that
causes any interference shall be
automatically muted. Where multiple
microphones are provided they shall
be configured via appropriate access
level and only a single microphone
can be in use at any one time. Prerecorded messages shall be stored in
non-volatile memory.
All mandatory Indicators shall be
visible at 3 m distance for general
indications and the supply of power
and at 0, 8 m distance for others. If
flashing indications are used, both
the on and off periods shall be a
minimum of 0,25 s, and the flash
frequency shall be a minimum of 1
Hz for voice alarm indications and 0,2
Hz for fault indications.
If the same led’s are used for
the indication of faults and
disablements, fault indications
shall flash and disablement shall
be steady. Mandatory indications
on an alphanumeric display shall
be legible for at least one hour
following the display of a new
indication of an alarm and 5 min
for fault or disablement conditions,
at 0,8 m distance, in ambient light
of 5 lux to 500 lux. The colours of
the general and specific led’s shall
be red for alarms, yellow for fault,
and disablements and green for
power. Where voice alarm automatic
message status indicators are
provided, it might be advantageous
to differentiate between evacuation
and alert message with red for
emergency messages and yellow for
alert messages.

part 17 short circuit isolators
Introduction
Scope
The purpose of a short-circuit isolator
is to limit the consequences of faults
in fire alarm circuits, both loops and
spurs. Sections of these circuits are
separated by installing short circuit
isolators at strategic locations, and
where applicable in accordance with
the national standard of the country
of installation where such a standard
exists, or where there is no country
standard then to the European
standard, CEN/TS54-14, or
ISO 7240-14.
This standard specifies the
requirements and methods of test
for short circuit isolators, for use in
fire detection and fire alarm systems.
Compliance shall be verified by
visual inspection or engineering
assessment and successfully tested
as described in clause 5. However,
for short circuit isolators which are
integrated into other devices already
covered by an existing European
Standard the environmental
conditioning shall be performed in
accordance with that EN.
In addition the short circuit isolators
should be installed in accordance
with the system manufacturers
design limitations to ensure that
circuits are not overloaded such
as to create volt drop which is also
likely to cause similar problems and
jeopardise the correct operation
of components.
section two
an introduction to the suite of EN54 standards
short circuit isolators
Requirements
If the short-circuit isolator
incorporates an integral status
indicator then this shall not be red.
Where it provides protection to
ancillary devices, failures of these
connections shall not prevent the
correct operation of the short circuit
isolator. If the isolating device is
detachable (i.e. it is attached to
a mounting base), then a means
shall be provided to detect the
removal of the device from the base
in order to give a fault signal. It
shall not be possible to change the
manufacturer’s settings or provide
for on-site adjustment of the short-
circuit isolator without the use of
a code or special tool. For each
setting the short circuit isolator shall
comply with the requirements of this
European Standard.
The functional testing is to verify
operation within the manufacturer’s
specification and to test each
condition claimed to cause it to
operate and at the maximum
specified current. The isolator should
open circuit when detecting a short
circuit condition and /or excess
current causing a volt drop below
a level at which the devices will
function correctly.

part 18 input/output devices
Scope
Introduction
This Standard specifies the
requirements, test methods and
performance criteria for input/output
devices connected to a fire detection
and fire alarm system, which may
transmit and/or receive signals which
are, necessary for the operation
of the fire detection and fire alarm
system and/or fire protection system.
The term input/output devices cover
a wide range of different types of
devices whose applications are
different. These may include, digital
inputs, monitored inputs for voltage,
together with relay outputs, voltage
outputs or solid state drivers to
switch external devices.
An input/output device may be
physically separate or its function
may be integrated into another
device. Control and indicating
equipment and ancillary control and
indicating equipment (e.g. repeater
panels and fire brigade panels) are
not covered by this Standard.
Compliance
In order to comply with this
Standard, the input/output devices
shall be verified by inspection and
engineering assessment and shall be
successfully tested as described in
Clause 5. If the input/output device
is detachable then a means shall be
provided to detect the removal of the
device from its base in order to give
a fault signal.
This Standard does not therefore
include detailed functional
requirements for the devices
themselves but requires that their
function is sufficiently specified
by the manufacturer and that they
function correctly in accordance with
that specification.
Devices shall be supplied with
sufficient data to ensure their correct
installation and operation. This
data shall include the parameters
necessary to define the input and/or
output functions (e.g. output voltage
and current ratings, alarm and fault
trip levels and logic levels).
For devices which rely on software
control, these shall meet the
requirements of 4.5.2, 4.5.3 and 4.5.4.

There are some aspects of the
detectors functionality therefore not
covered by this standard.
An aspirating smoke detector is
one in which air and aerosols are
drawn through a sampling device
and carried to one or more smoke
sensing elements by an integral fan
or pump.
To comply with this standard the
detector shall meet the requirements
of this clause, which shall be verified
by inspection and engineering
assessment, and, when successfully
tested in accordance with those
described in Clause 6.
The response of an aspirating
smoke detector is dependent upon
both the sensitivity settings of the
smoke sensing element and the
design of the sampling device; e.g.
pipework and sampling points. In
some detectors the smoke sensing
sensitivity can be adjusted in order
to suit the application and sampling
device.
The manufacturer’s settings should
not be accessible to change without
the need for a password, special tool
or by the breaking or removal of a
seal. The adjustments may be made
at the detector or at the control and
indicating equipment.

section two
an introduction to the suite of EN54 standards
aspirating smoke detectors
Changing the sensitivity settings
can affect the classification of the
installed detector. If it is possible
to reconfigure the detector such
that it no longer complies with the
standard, then this shall be clearly
marked on the detector or in the
associated data. The provision of
“drift compensation” to counter the
effects of a build-up of dirt in the
detector, and /or the provision of
algorithms to suit an environment
shall not significantly reduce the
detector’s sensitivity to slowly
developing fires.
The sampling pipes and fittings
shall have adequate mechanical
strength and temperature resistance
in accordance with EN 61386-1 to at
least Class 1131. Pipes which are not
classified by the manufacturer of the
detector shall either be tested, as
part of the approval, or be supported
by evidence that the requirements of
this standard are met.
An airflow fault signal will be
generated, within 300secs, when the
flow is outside the manufacturer’s
operational limits. The airflow shall
be monitored to detect leakage or
obstruction of the sampling device
or pipework sampling point(s).
This time is additional to any delay
between signalling the fault and its
indication at the control panel and is
to allow for spurious short term flow
variations which would otherwise
cause unwanted fault signals.
The power for the aspirating detector
shall be supplied by a separate
power supply complying with EN
54-4 which may be within the main
control and indicating equipment.
Aspirating Smoke Detector systems
are classified based upon the
sensitivity setting as shown in the
table below. The method used for
determining the classification is
likely to take into account the sizes
and number of sampling points, their
position along the sampling device/
pipe, the sensitivity of the detector
and the sampling device/pipework
arrangement and its length.

part 21 alarm transmission and fault warning routing equipment
Scope
This Standard specifies the
requirements, test methods and
performance criteria for fire alarm
and fault routing transmission
equipment for use with fire detection
and fire alarm systems. If functions
other than those specified in this
Standard are provided, they shall not
jeopardize the functionality required
for compliance. Transmission
equipment can be type 1 where a
dedicated alarm path exists and
type 2 for a digital communicator
using the public switched telephone
network, both in accordance with
EN50136-1-1.
Requirements
The alarm transmission routing
equipment shall be capable of
receiving fire alarm signals from
the Control and indicator panel
and faults from the transmission
network which together with
acknowledgements from the alarm
receiving centre will be transmitted
to the control and indicator panel. It
shall also be capable of transmitting
fire alarm signals to the alarm
receiving centre.
The fault warning routing equipment
shall be capable of receiving fault
warning signal from the control
and indicator panel and from
the transmission network and
transmitting faults to both the control
and indicator panel and the alarm
receiving centre.
Indication of signals shall be
provided at the transmission
equipment, via led’s, or at the control
and indicator equipment for both the
received acknowledgement signal
from the alarm receiving centre as
defined in EN 50136-2-1 and at least
one common fault warning be used
to indicate the following:
1) if the acknowledgement signal
is not received at the routing
equipment within 100 s for type 1
and 240 s for type 2 of the initiation
of the transmitted fire alarm.
2) a failure within the routing
equipment (e.g. power supply
failure).
3) a failure within the alarm
transmission network.
4) where the routing equipment and
the fire alarm control panel are in
separate enclosures and where a
fault exists on the interconnection
path, a fault signal shall be indicated
locally and transmitted to the alarm
receiving centre.
page 139
section two
an introduction to the suite of EN54 standards
alarm transmission and fault warning routing equipment
The routing equipment enclosure
shall be of robust construction,
consistent with the recommended
installation method and shall be a
minimum of IP30 of EN 60529.
All light emitting indicators shall be
clearly labelled with the information
being legible at 0, 8 m distance in
an ambient light intensity from 100
lux to 500 lux. If flashing indications
are used, the on off-periods shall be
a minimum of 0, 25 s and the flash
frequency not less than 0, 2 Hz for
fault indications. The light-emitting
indicators shall be yellow for fault
and red for the indication of the
acknowledgement. All terminals and
fuses shall be clearly labelled.
If the processing and transmission
of fire and fault signals is achieved
in separate equipment then both
can operate simultaneously. If the
signals are combined in a single
piece of equipment then the fire
signal shall take priority. A fault
in any transmission path between
the routing equipment and the
transmission network (as defined
in EN 50136-1-1) shall not affect the
routing equipment or any other
transmission path.
The power supply for the
transmission equipment shall be
in accordance with EN54-4. If the
power supply is within a separate
enclosure then duplicate paths will
be arranged so that failure in one
does not isolate the transmission
equipment. The change over from
the primary to standby power supply
shall not affect any indications other
than those specifically associated
with power supplies. Any provision
for disconnecting or adjusting the
power supply to the equipment will
not be readily accessible, without the
required access.

part 23 fire alarm devices – visual alarm devices
Introduction
Requirements
This Standard specifies the
requirements, test methods and
performance criteria for visual alarm
devices in a fire detection and alarm
system which are intended to signal
a warning of a fire.
It applies only to pulsing or flashing
visual alarm devices, such as xenon
or rotating beacons.
The purpose of a visual fire alarm
device is to warn persons within, or
close to a building of the outbreak
of a fire. This Standard allows
manufacturers to specify devices
in terms of the range at which the
required illumination is met. Three
categories are defined; for ceiling
and wall mounted devices and an
open category. The maximum range
of the visual alarm device is tested
by measuring its light output in
the surrounding hemisphere. As
the light output can vary over time
a test is made to check that any
variation is acceptable. This Standard
gives common requirements for
the construction as well as for
their performance under varying
conditions Devices are classified as
Type A, indoor and Type B, outdoor.
The degree of protection provided by
the enclosure shall be IP21 for Type
A and IP33 for type B, in accordance
with EN 60529.
In order to comply devices shall meet
the requirements of Clause 4, which
shall be verified by visual inspection
or engineering assessment and shall
be successfully tested as described
in Clause 5.
The device shall be rated for a
minimum of 100 hours which will
not affect its ability to cycle on
and off as required as part of the
compliance testing. This requirement
does not apply to the capacity of any
integral batteries used as a means of
providing local standby power.
page 143
section two
an introduction to the suite of EN54 standards
fire alarm devices – visual alarm devices
The capacity and charging
requirements of such batteries
should meet the requirement of
the system.
Access to the device shall be
restricted by the use of special
screws or tools and it should
not be possible to change the
manufacturer’s settings without use
of the same or by breaking a seal.
If on site adjustment of the device
settings is provided, then the factory
setting, which complies with this
standard, should be clearly displayed
for each. Any settings which are not
compliant with this standard shall
only be accessible by the same
means and it should be clearly
displayed, either on the device or
in data format that the device does
not comply with this standard. The
adjustments may be carried out
either at the device or via the control
and indicator equipment.
Visual alarm devices shall meet the
requirement for coverage as either
a ‘C’, ceiling mounted, or ‘W’, wall
mounted, or ‘O’, open class device.
Category C devices shall be further
specified as C-x-y where: x is either
3, 6 or 9 and is the maximum
ceiling mounting height in metres
and y is the diameter, in metres,
of the coverage. e.g. C-3-12 would
represent a 12 metre diameter
coverage when mounted at 3 metres
Category W devices shall be further
specified as W-x-y where x is the
maximum wall mounting height
in metres, with a minimum value
of 2.4 m; and y is the width of a
square room, in metres covered by
the device. e.g. W-2,4-6 represents a
device mounted at a height of 2.4m
in a room measuring 6mx6m.
For category O devices the coverage
volume in which the required
illumination is achieved shall
be specified.
The visual alarm device shall
produce either red or white light
of at least 1 candela for 70 % of all
measurement points and shall not
exceed 500 cd for any measurement
points. The flash rate shall be
between 0.5 and 2 Hz measured at 10
% of the peak values of consecutive
leading edges of the first pulse of
each flash. The maximum on time,
measured between the leading and
trailing edge shall not exceed 0.2 s.
The light temporal pattern and
frequency of flashing may vary in
different countries and therefore
reference needs to be made to
local regulations.
Flashing lights may require
synchronization to prevent the
possibility of a flash frequency/

temporal pattern; that could
adversely affect some occupants
inducing epileptic fits when multiple
devices are within a field of view. In
such cases, devices shall meet the
requirements of the test described in
5.3.7.
Technical data regarding both
installation and maintenance should
be provided with each device or in
supporting documentation.

part 24 components of voice alarm systems - loudspeakers
Introduction
Requirements
This Standard specifies the
requirements, test methods and
performance criteria for voice alarm
loudspeakers for use with fire
detection and fire alarm systems
.For compliance, voice alarm
loudspeakers shall be verified by
visual inspection or engineering
assessment and shall be successfully
tested as described in Clause 5.
This standard recognizes that
the performance of voice alarm
loudspeakers will vary according
to the nature of the space into
which they are installed. It therefore
specifies the minimum requirements
and a common method for testing
their operational performance
against parameters specified by the
manufacturer.
The purpose of a voice alarm
loudspeaker is to provide intelligible
warning to person(s) of a fire,
whilst at the same time advising
appropriate methods of evacuation.
Providing such information speeds
up a person’s response time to
an incident, removes uncertainty,
allowing evacuation times to be
reduced. Voice alarm loudspeakers
need to achieve a minimum
acoustical performance, as well
as constructional and environmental
requirements, to be suitable for
use in fire detection and fire
alarm systems.
As the types of loudspeaker included
are electromechanical devices
without sensitive electronics,
electromagnetic compatibility (EMC)
tests are excluded. Loudspeakers
are suitable for either indoor, type
A or outdoor, type B, applications
as specified. Type B loudspeakers
can be beneficial in some indoor
situations where high temperature
and/or humidity are present. For
type A the degree of protection
required is to IP21 and for type B,
IP33 of EN 60529.
page 149
section two
an introduction to the suite of EN54 standards
components of voice alarm systems - loudspeakers
Loudspeakers suitable for special
applications or hazardous areas are
not covered by this standard.
The voice alarm loudspeaker shall
be rated for a minimum of 100 hours
operation at the rated noise power
specified by the manufacturer.
Access to the device will be limited
and require special tools, codes, or
be restricted by the use of hidden
screws or seals.
Voice alarm loudspeakers shall be
clearly marked and in addition to
the standard data, detailed in the
overview shall contain information
relative to the rated noise voltage for
transformer-coupled loudspeakers;
the rated impedance for directcoupled loudspeakers; the rated
noise power at the highest power
setting; and the various power
settings (e.g. transformer tapping
options for transformer-coupled
loudspeakers).
Some loudspeakers are a
combination of one or more
housings together with a termination
box and an interconnecting cable.
The housing(s), cable(s) and
terminal box should be considered
to be ‘the loudspeaker’ for the
purposes of this Standard. Examples
include: pendant types and those
with adjustable orientation such as
horn or column loudspeakers and
loudspeaker arrays.
The maximum sound pressure level
is expressed in dB and measured
at a distance of 4 metres from the
reference point on the reference
axis over a period of at least 30s.
The loudspeaker shall be deemed
to conform to the rated sound
pressure test if the sound pressure
level is greater or equal to the value
specified by the manufacturer.
The loudspeakers shall be
constructed using materials capable
of withstanding the tests detailed in
clause 5.
Plastic materials shall conform to
EN60695-11-10 when operating on a
voltage ≤ 30V RMS or 42.4 V dc with
less than 15 watts of power, or, EN
60695-11-20 when operating on a
voltage ≥ 30V RMS or 42.4 V dc with

an introduction to the suite of EN54 standards
part 25 components using radio links
Introduction
Scope
The purpose of this Standard is
to define additional requirements
to other parts of EN 54 that allow
compliant radio fire detection
systems and components to be
at least as efficient and stable as
approved wired fire detection
systems. Systems and components
are covered because it is difficult to
describe the components separately.
Limitations with respect to the
use of radio components may be
specified in national technical rules
or guidelines and consideration
should be given to the frequencies,
bands and channels used by radio
based systems. The requirements in
this standard shall apply together
with those in other parts of EN54
where the component has the same
function as that covered in the other
standard, and when not specifically
covered in this standard. e.g. A heat
detector installed on a wireless
system will comply with EN54-5
This Standard specifies the
requirements, test methods and
performance criteria for both
systems and components used in
fire alarms systems which use radio
frequency links to communicate.
Compliance with this standard
requires the components to meet
these requirements which shall
be verified by visual inspection
or engineering assessment, and
successfully tested as described in
Clause 8.
Where combined wired and radio
systems are used the relevant part
of EN54 together with this standard
will both apply. The requirements
for wired systems are superseded
or modified by this standard. This
document does not cover those
issues which relate to national
regulations which may vary from
country to country, and which may
include frequencies, power and
limitations of losses on circuits or
radio links.
section two
an introduction to the suite of EN54 standards
components using radio links
Requirements
The manufacturer shall provide a
safeguard to ensure any attenuation,
which may be caused by differing
influences on site, does not affect
the radio link in such a way as to
prevent communication between
components. The limits will be at
least 10dB for frequencies up to
10MHz and as defined in Annex
B for frequencies greater than
10MHz. The system shall use a
secure transmission protocol which
ensures that signals are not lost.
Each component will be marked
individually as an indication that
they belong to the same system and
components belonging to different
systems should not be compatible.
The system should demonstrate
immunity to its own radio influences
and others on the spectrum.
Those produced as a result of
electromagnetic affects are covered
by those guidelines in EN50130-4.
Influences as a result of a direct
attack is not covered or required
in the EN54 standards. Where
two or similar systems from the
same manufacturer are operating
within range it shall be ensured
that they do not affect each other.
The manufacturer shall also ensure
that signal transmission is possible,
without causing interference, even
if other users are working in the
same band. Interference to a single
receiver shall not cause alarm
or fault messages at the control
equipment. If any radio linked
component is unable to transmit a
message to the CIE within EN 54-2
defined periods it shall be indicated
in less than 100 s.
Power supplied to the components
shall be via a primary battery or
an external power supply unit
complying with EN54-4. Components
powered by the independent power
source shall be contained within the
same enclosure. The battery shall
have a minimum life of 3 years. The
system requirements shall not cause
the battery to discharge below 85%
by end of life. The remaining 15 % of
the rated capacity takes account of
self-discharge of the power source.
All components powered from the
independent power source shall be
capable of transmitting a fault signal
(low power) before the power source
fails whilst still functioning.

BS EN 50020
Scope
This European standard was
approved by CENELEC whose
members are bound to comply. This
gives this standard, with conditions,
the status of a national standard.
The Standard specifies the
construction and testing of
intrinsically safe circuits, apparatus
and associated apparatus for use in
potentially explosive atmospheres.
It applies to electrical apparatus
in circuits which are safe and
incapable of causing an explosion.
The standard also applies to
apparatus located outside the
potentially hazardous area, or which
are protected by another type of
protection listed in EN 50014, where
the intrinsic safety of the circuit may
depend upon the apparatus itself.
Where intrinsically safe apparatus
is required to be Category 1 G in
accordance with EN 50284 it must
also comply with the requirements
in this standard. Where it is required
to be Category M1 equipment in
accordance with EN 50303 it must
also comply with the requirements of
this standard.
Note: EN 54 ceases to have
harmonised status under the ATEX
directive and was replaced by EN

Requirements
The requirements of this standard
apply to both levels of Intrinsically
safe apparatus protection “ia” and
“ib,
unless otherwise stated, and In the
determination of the level, failure of
components and connections shall
be considered in accordance with 7.6.
When the maximum voltage is
applied to the intrinsically safe
circuits and apparatus of level “ia”,
it shall not be capable of causing
ignition in normal operation when
up to two countable and a number of
none countable faults, which present
the most difficult conditions, are
present.
When the maximum voltage is
applied to the intrinsically safe
circuits and apparatus of level “ib”,
it shall not be capable of causing
ignition in normal operation when
up to one countable and a number of
page 157
section two

electrical apparatus for
potentially explosive atmospheres Intrinsic safety ‘I’
none countable faults, which present
the most difficult conditions, are
present.
(Note: non countable faults are those
in non-conforming components
of the apparatus known as the
associated apparatus; countable
faults are those in components
which conform to the constructional
requirement of this standard, known
as intrinsically safe apparatus.
The application for ia covers all
zones whereas ib devices are only
approved for use in zone 1 and 2.
Simple apparatus can be defined
as being a passive component such
as a switch, or one where sources
of stored energy are within defined
parameters, for example capacitors,
or where components can only
generate very low levels of energy,
which is also within the defined
parameters, for example photocells.
When simple apparatus is located
in the hazardous area, it shall be
temperature classified.
Where simple apparatus is to be
located in a Category 1 G or M1, then
the apparatus shall also comply with
the requirements of EN 50284 or EN
50303 as applicable.
Temperature classification, (T16) defines the maximum surface
temperature of any surface exposed
to the atmosphere and ensures
it remains below the ignition
temperature.
Intrinsically safe and associated
apparatus require an adequate
enclosure so as to secure the
method of protection, which for
Group II is IP20 in normally benign
environments and for Group I is IP
54, in accordance with EN 60529,
(degree of protection provided by
enclosures).
The maximum current in any
insulated cable shall not exceed that
specified by the manufacturer.
Terminals for intrinsically safe
circuits shall be separated from nonintrinsically safe circuits including
where intrinsic safety can be
impaired by disconnected external
wiring coming into contact with
conductors or components. Terminals
should be suitably arranged that
components will not be damaged
when connections are made and
where separation is achieved by
distance then the clearance between
terminals shall ensure any bare
conducting parts are at least 50mm
apart and unlikely to come into
contact, even if dislodged.
section two
an introduction to the suite of EN54 standards
electrical apparatus for
potentially explosive atmospheres Intrinsic safety ‘I’
When separation is accomplished
by locating terminals for intrinsically
safe and non-intrinsically safe
circuits in separate enclosures by
use a partition and a single cover,
the partitions separating terminals
shall extend to within 1,5 mm of the
enclosure walls, or shall provide
a minimum distance of 50 mm
between the bare conducting parts
of the external conductors. Metal
partitions shall be earthed and have
sufficient strength and rigidity to
prevent any damage during the
connection of field wiring. The
clearance between the terminals of
separate intrinsically safe circuits is
given in Table 4 of the standard. In
addition, the clearances between the
bare conducting parts of connected
external conductors shall be at least
6 mm and between any conducting
parts of external conductors and
earthed metal shall be 3 mm.
Plugs and sockets used for
connection of external intrinsically
safe circuits shall be separate from
and non-interchangeable with those
for non-intrinsically safe circuits.
Protection shall be provided within
intrinsically safe apparatus to
prevent the reversal of the polarity
of supplies including within a battery
where this could occur. For this
purpose, a single diode shall be
acceptable.
Where a relay coil is connected to an
intrinsically safe circuit, the contacts
in normal operation shall not exceed
their manufacturer’s rating and shall
not switch more than 5 A. or 250 V
or100 VA. When the values exceed
these but do not exceed 10 A or
500 VA, the values in Table 4 for the
relevant voltage shall be doubled.
For higher values, all circuits shall
be connected to the same relay only
if they are separated by a suitable
earthed metal or insulating barrier.
Where a relay has some contacts in
intrinsically safe and others in nonintrinsically safe circuits, the contacts
shall be separated by an insulating
or earthed metal barrier in addition
to Table 4. The relay shall be designed
such that a broken or damaged
contact cannot impair the integrity of
the separation.

Where earthing of enclosures
and equipment is required to
maintain the type of protection (ia
or ib), the cross-sectional area of
any conductors, connectors and
terminals used shall be rated to carry
the maximum possible continuous
current under the conditions
specified in clause 5. Components
shall also conform to clause 7.Where
a connector carries a conductor
such as an earth connection on
which intrinsic safety depends,
the connector shall incorporate at
least three independent connecting
elements for “ia” circuits and two for
“ib” circuits and be rated to carry the
maximum possible current.
Where a casting compound is used
to exclude a potentially explosive
atmosphere from components and
intrinsically safe circuits, it shall
conform to 6.4.4, and where used to
reduce the ignition capability of hot
components its profile shall reduce
the maximum surface temperature of
the casting compound to the desired
value.
In both normal operation and
fault conditions, any remaining
components on which the type of
protection depends, shall not operate
at more than two-thirds of their
rating. These maximum rated values
shall be the normal commercial
ratings specified by the manufacturer
of the component.
Connectors shall be designed such
that interchangeability with others
in the same apparatus is impossible
unless it does not result in an unsafe
condition or the connectors are
easily identified.
Where an explosion could adversely
affect intrinsic safety, the use of cells
and batteries, capable of exploding,
under certain conditions must be
confirmed as being safe for use in
intrinsically safe and associated
apparatus for both ia and ib
applications. They shall be of a type
where leakage onto components is
not possible and preferably should
be sealed. Batteries which are not
sealed shall be tested in accordance
with 10.9.2

The diodes and resistors within a
safety barrier limit the voltage and
current applied to an intrinsically safe
circuit. These assemblies are used as
interfaces between intrinsically safe
and non-intrinsically safe circuits,
and shall be subjected to the routine
test of 11.1. The requirements of Table
4 shall also apply except that lines 5,
6 and 7 do not apply to opto-coupled
barriers; e.g. galvanic isolators. In
addition to any connection which
may be at earth potential, the diode
type barrier shall have a connection
to earth through a 4mm(min)
insulated wire.
Intrinsically safe and associated
apparatus shall be marked in
accordance with EN 50014.
For associated apparatus, the symbol
EEx ia or EEx ib shall be enclosed in
square brackets.
Connection facilities including
terminal boxes, plugs and sockets
shall be clearly marked and
identifiableand where colour coded,
it shall be light blue.

EN 12094-1, Requirements and test
methods for electrical automatic
control and delay devices
Scope
This Standard specifies the
requirements and test methods for
electrical automatic control and
delay devices (device) for use with
automatic fire detection and fire
alarm systems and CO2-, Inert Gasor Halocarbon Gas-Fire Extinguishing
Systems. The standard specifies both
compulsory and optional functions.
Additional functions associated with
fire extinguishing can be provided,
but are not covered by this standard.
Requirements
The electric auto control and delay
may be an independent unit or
an integral part of a control and
indicator panel. If the devices are
integral to a control panel and use
the same indication and controls
as that as the fire detection and
alarm system then the requirements
for this standard and EN54-2 shall
both be fulfilled. The power supply
requirements shall be in accordance
with EN54-4 and there shall be
duplicate paths between the two
if the power supply is not integral
to the automatic control and delay
device.
The functionality of the device shall
be in accordance with clauses 4, 5, 6
and 9.3 of this standard. Testing is as
detailed in section 9.
The device shall be classified for
one of the following based upon the
intended ambient conditions:
Class A: temperature range of - 5 °C
to + 40 °C;
Class B: temperature range of – 20 °C
to + 50 °C;
Class C: temperature range of - 5 °C
to + 40 °C and corrosive atmosphere
class 3C4 of EN 60721-3-3;
Class D: temperature range of - 20 °C
to + 50 °C and corrosive atmosphere
class 3C4 of EN 60721-3-3.
page 163
section two
an introduction to the suite of EN54 standards
fixed firefighting systems components for gas extinguishing systems
The device shall receive and
process all the necessary functions
associated with the electrical control
of the extinguishing system and
indicate signals for each flooding
zone, within 3 secs of the input
being received. The compulsory
functions to be performed by the
device shall include receiving
inputs from both the fire detection
system and a manual station
connected directly to the device.
On receipts of input signals, a
signal to the release mechanism
and to a distinctive continuous
alarm sounder, which shall only be
silenced by an appropriate access
level and after confirmation of a
discharge occurring, shall occur
within 1 further sec unless a delay is
incorporated within the programme.
The activation of an emergency
hold button, will be displayed on the
device, both audibly and visually,
and if occurring during the predischarge warning time will affect a
change to the signal from the alarm
devices in the protected area. Faults
affecting the emergency hold device
shall be recognised and indicated
within 2secs and prevent the
transmission of the extinguishing
signal. Any delay time shall be
adjustable between 0 and 60 sec.
The device shall be capable of
displaying all conditions including
device activated, fault and
extinguishing system gas released.
The released condition can be
established upon receipt of a signal
indicating a flow of the gas, (both
audibly and visually), or upon the
triggering of the extinguishing
ignal output.
The monitoring of components such
as a loss of gas will in the event of
an abnormal condition indicate a
fault, clearly displaying the nature
of the condition and within 100s of
its occurrence.
If a signal is sent to an external
signalling unit, separate indication
will be provided to that affect.
National guidelines can require
other/different functionality, e.g. a
separate indicator per flooding zone
or a maximum number of monitored
components per indicator.
Where an alphanumeric display
is used to provide the required
information, additional led’s for
the “Activated”, “Released”, “Fault”,
“Disabled” and “Blocked” conditions
shall be provided.
The display should be capable of
indicating all released flooding zones
simultaneously. If it has insufficient
numbers of fields the zones shall be
section two
an introduction to the suite of EN54 standards
fixed firefighting systems components for gas extinguishing systems
indicated by separate light emitting
indicators.
A field shall consist at least of 16
characters, where it cross refers to
other information or 40 characters,
where the display provides a full
description.
Faults signals shall be displayed
for any open, short circuit or earth
fault associated with all input and
output devices, including monitoring
circuits, disablement devices, signal
transmission equipment and power
supplies, both AC and DC; or if there
is a fault affecting the operating
program in any software controlled
device. In which case not more than
one flooding zone shall be affected
except where a room and its void are
subdivided into two zones.
Optional functions which may
be performed by the device can
include, delaying the signal to
the release mechanism whilst
providing a distinct intermittent predischarge warning, which shall not
be interrupted, shortened or reset
by a signal from the emergency
hold button. To provide indication
of a flow of agent together with the
monitoring and control of valves
and other associated components.
If an emergency hold button is fitted
it shall signal its status to the device
together with any other mechanical
parts capable of disabling the
extinguishing system. The device
shall receive and display any
changeover from a manual to an
automatic status.
If a controlled discharge of
extinguishing agent is required this
will be performed by the device as
will the initiating of any secondary
discharges. A secondary discharge
will result from a second manual
input, after the initial discharge and
whilst the sounders in the area are
still operating.
Signals to pilot cylinders, spare
cylinders, optical devices, doors,
ventilation plant, required as part
of the cause and effect will be
performed by the device.
If the information is transmitted to an
external centre this shall be indicated
page 165
section two
an introduction to the suite of EN54 standards
fixed firefighting systems components for gas extinguishing systems
by a separate light emitting indicator
and/or by an alphanumeric display.
If a device is intended to control the
flooding time, it shall be adjustable
from a minimum time specified by
the manufacturer up to at least 300 s.
In some European countries there
are regulations stipulating that the
activated condition can only be
established after the receipt of two
input signals, from independent
circuits, one from the fire detection
and alarm system and a further
signal from the device. The first
input must be both audibly and
visually indicated and outputs such
as plant shutdown may be triggered.
If the same indicator is used for
both inputs, the first input shall
be indicated with a flashing light,
changing to a steady light when the
second input is received.
The processing of the input signal
shall have the highest priority unless
a signal from an emergency hold
or abort button is present; a fault
exists within its circuit or if the gas
discharge is disabled.
If the processing of the input signal
has started, the disablement of any
gas zone is prohibited.
Following a reset command the
activated, released and fault
conditions will be reset and the
display will provide indication of
the current status, including any
not normal conditions, within 20 s.
Provision shall be made to inhibit
the reset , either for a period up to 30
seconds or until an end of discharge
signal is received. Disablements
shall not be removed by the reset
function.
