Fire detection and fire alarm systems - Point detectors using a combination of detected fire phenomena

The European Standard prEN 54-15 specifies requirements, test methods and performance criteria for point-type multi-sensor fire detectors for use in fire detection systems installed in buildings (see EN 54-1:1996), incorporating in one mechanical enclosure sensors which detect more than one physical or chemical phenomenon of a real fire. The overall fire performance is determined utilising a combination of the detected phenomena.  The allowed phenomena are aerosol (i.e. smoke), heat, combustion gases and electromagnetic radiation.  Multi-sensor fire detectors with special characteristics and developed for specific risks are not covered by this standard.

Brandmeldeanlagen - Teil 15: Punktförmige Mehrfachsensormelder

Diese Europäische Norm prEN 54-15 legt Anforderungen, Prüfverfahren und Leistungsmerkmale für punkt-förmige
Mehrfachsensormelder für die Anwendung in Brandmeldeanlagen in Gebäuden (siehe EN 54-1:1996)
fest. Die Melder enthalten in einem Gehäuse Sensoren zur Erfassung mehrerer unterschiedlicher
physikalischer oder chemischer Phänomene eines realen Brandes. Das Gesamtverhalten im Brandfall wird
durch Auswertung einer Kombination von erfassten Brandphänomenen bestimmt. Folgende Phänomene
können erfasst werden: Aerosole (d. h. Rauch), Wärme, Verbrennungsgase und elektromagnetische
Strahlung.
Mehrfachsensormelder, die spezielle Eigenschaften haben und für Fälle mit besonderen Risiken entwickelt
wurden, sind nicht Gegenstand dieser Norm.
ANMERKUNG 1 Diese Europäische Norm erfasst Prüfungen, durch die der Nachweis erbracht wird, dass die Melder
auch dann ansprechen, wenn keine direkte Sichtlinie zum Brandherd besteht.
ANMERKUNG 2 Einige Meldertypen enthalten radioaktive Werkstoffe. Die nationalen Anforderungen für den Schutz
gegen ionisierende Strahlung sind in den Ländern unterschiedlich und werden deshalb in der vorliegenden Norm nicht
festgelegt.

Systemes de détection et d'alarme incendie - Partie 15 : Détecteurs ponctuels fonctionnant sur le principe d'une combinaison de phénomenes détectés

La présente Norme européenne prEN 54-15 spécifie les exigences, les méthodes d’essai et les criteres de
performance des détecteurs d’incendie ponctuels multicapteurs utilisés dans les systemes de détection
d’incendie dans les bâtiments (voir l’EN 54-1:1996), comprenant dans une meme enveloppe mécanique des
capteurs qui détectent plusieurs phénomenes physiques ou chimiques d’un feu. Les performances générales
de comportement au feu sont déterminées a l’aide d’une combinaison de phénomenes détectés. Les
phénomenes admis sont : aérosol (c’est-a-dire fumée), chaleur, gaz de combustion et rayonnement
électromagnétique.
Les détecteurs d’incendie ponctuels multicapteurs possédant des caractéristiques particulieres, conçus pour
des risques spéciaux, ne sont pas couverts par cette norme.
NOTE 1 Les essais sont inclus pour confirmer que les capteurs ne dépendent pas uniquement d’une ligne de vision
directe entre le feu et le capteur.
NOTE 2 Certains types de détecteurs peuvent contenir des matériaux radioactifs. Les exigences nationales pour la
protection contre les rayonnements varient d’un pays a l’autre et ne sont par conséquent pas spécifiées dans la présente
norme.

1. Scope
The European Standard prEN 54-15 specifies requirements, test methods and performance criteria for point-
type multi-sensor fire detectors for use in fire detection systems installed in buildings (see EN 54-1:1996),
incorporating in one mechanical enclosure sensors which detect more than one physical or chemical
phenomenon of a real fire. The overall fire performance is determined utilising a combination of the detected
phenomena. The allowed phenomena are: aerosol (i.e. smoke), heat, combustion gases and electromagnetic
radiation.
Multi-sensor fire detectors with special characteristics and developed for specific risks are not covered by this
standard.
NOTE 1 Tests are included to confirm that detectors do not rely solely on a direct line of sight between the fire and the
detector.
NOTE 2 Certain types of detector contain radioactive materials. The national requirements for radiation protection
differ from country to country and they are not specified in this standard.

3. Terms and definitions
For the purposes of this standard, the terms and definitions given in EN 54-1:1996 and the following apply:
3.1 response threshold value
aerosol density in the proximity of the specimen at the moment that it activates an alarm signal
NOTE 1 See 5.1.5.
NOTE 2 The response threshold value may depend on signal processing in the detector and in the control and indicating
equipment.
4. Requirements
4.1 Compliance
In order to comply with this standard the detector shall meet the requirements of this clause, which shall be
verified by visual inspection or engineering assessment, shall be tested as described in clause 5 and shall
meet the requirements of the tests.
4.2 Individual alarm indication
Each detector shall be provided with an integral red visual indicator, which shall be activated at the same time
as the alarm and shall remain activated until the alarm condition is reset, to enable identification of the
individual detector. Where other conditions of the detector can be visually indicated, they shall be clearly
distinguishable from the alarm indication, except when the detector is switched into a service mode. For
detachable detectors the indicator may be integral with the base or the detector head. The visual indicator
shall be visible from a distance of 6 m directly below the detector, in an ambient light intensity up to 500 lux.
4.3 Connection of ancillary devices
Where the detector provides for connections to ancillary devices (e.g. remote indicators, control relays),
open- or short-circuit failures of these connections shall not prevent the correct operation of the detector.
4.4 Monitoring of detachable detectors
For detachable detectors, a means shall be provided for a remote monitoring system (e.g. the control and
indicating equipment) to detect the removal of the head from the base, in order to give a fault signal.
4.5 Manufacturer's adjustments
It shall not be possible to change the manufacturer's settings except by special means (e.g. the use of a
special code or tool) or by breaking or removing a seal.
4.6 On-site adjustment of response behaviour
If there is provision for on-site adjustment of the response behaviour of the detector then:
6

---------------------- Page: 8 ----------------------
oSIST prEN 54-15:2006
prEN 54-15:2006 (E)
a) for each setting, at which the manufacturer claims compliance with this standard, the detector shall
comply with the requirements of this standard, and access to the adjustment means shall only be possible
by the use of a code or special tool or by removing the detector from its base or mounting;
b) any setting(s), at which the manufacturer does not claim compliance with this standard, shall only be
accessible by the use of a code or special tool, and it shall be clearly marked on the detector or in the
associated data, that if these setting(s) are used, the detector does not comply with the standard.
NOTE These adjustments may be carried out at the detector or at the control and indicating equipment.
4.7 Protection against the ingress of foreign bodies
The detector shall be so designed that a sphere of diameter (1,3 ± 0,05) mm cannot pass into the sensor
chamber(s).
NOTE This requirement is intended to restrict the access of insects into the sensitive parts of the detector. It is known
that this requirement is not sufficient to prevent the access of all insects, however it is considered that extreme restrictions
on the size of access holes may introduce the danger of clogging by dust etc. It may therefore be necessary to take other
precautions against false alarms due to the entry of small insects.
4.8 Response to slowly developing fires
The provision of "drift compensation" (e.g. to compensate for sensor drift due to the build up of dirt in the
detector) shall not lead to a significant reduction in the detector's sensitivity to slowly developing fires.
Since it is not practical to make tests with very slow increases of the measured phenomena, an assessment of
the detector's response to slowly developing fires shall be made by analysis of the circuit/software, and/or
physical tests and simulations.
The detector shall be deemed to meet the requirements of this clause if this assessment shows that:
a) for any rate of increase in smoke density R of smoke of the composition produced by test fire TF2, which
is greater than A/4 per hour (where A is the detector’s initial uncompensated response threshold value),
the time for the detector to give an alarm does not exceed 1,6 x A/R by more than 100 s; and
b) the range of compensation is limited such that, throughout this range, the compensation does not cause
the response threshold value of the detector to exceed its initial value by a factor greater than 1,6.
NOTE Further information about the assessment of these requirements is given in Annex N.
4.9 Marking
Each detector shall be clearly marked with the following information:
a) the number of this standard (i.e. EN 54-15);
b) the name or trademark of the manufacturer or supplier;
c) the model designation (type or number);
d) the wiring terminal designations;
e) some mark(s) or code(s) (e.g. serial number or batch code), by which the manufacturer can identify, at
least, the date or batch and place of manufacture, and the version number(s) of any software, contained
within the detector.
For detachable detectors, the detector head shall be marked with a), b), c) and e), and the base shall be
marked with, at least c) (i.e. its own model designation) and d).
Where any marking on the device uses symbols or abbreviations not in common use then these shall be
explained in the data supplied with the device.
7

---------------------- Page: 9 ----------------------
oSIST prEN 54-15:2006
prEN 54-15:2006 (E)
The marking shall be visible during installation of the detector and shall be accessible during maintenance.
The markings shall not be placed on screws or other easily removable parts.
4.10 Data
Detectors shall either be supplied with sufficient technical, installation and maintenance data to enable their
1)
correct installation and operation or, if all of these data are not supplied with each detector, reference to the
appropriate data sheet shall be given on, or with, each detector.
4.11 Additional requirements for software controlled detectors
4.11.1 General
For detectors which rely on software control in order to fulfil the requirements of this standard, the
requirements of 4.11.2, 4.11.3 and 4.11.4 shall be met.
4.11.2 Software documentation
4.11.2.1 The manufacturer shall submit documentation which gives an overview of the software design. This
documentation shall be in sufficient detail for the design to be inspected for compliance with this standard and
shall include at least the following:
a) a functional description of the main program flow (e.g. as a flow diagram or structogram) including:
1) a brief description of the modules and the functions that they perform;
2) the way in which the modules interact;
3) the overall hierarchy of the program;
4) the way in which the software interacts with the hardware of the detector;
5) the way in which the modules are called, including any interrupt processing.
b) a description of which areas of memory are used for the various purposes (e.g. the program, site specific
data and running data);
c) a designation, by which the software and its version can be uniquely identified.
4.11.2.2 The manufacturer shall have available detailed design documentation, which only needs to be
provided if required by the testing authority. It shall comprise at least the following:
a) an overview of the whole system configuration, including all software and hardware components;
b) a description of each module of the program, containing at least:
1) the name of the module;
2) a description of the tasks performed;

1)
To enable correct operation of the detectors, these data should describe the requirements for the correct
processing of the signals from the detector. This may be in the form of a full technical specification of these signals, a

reference to the appropriate signalling protocol or a reference to suitable types of control and indicating equipment etc.
8

oSIST prEN 54-15:2006
prEN 54-15:2006 (E)
3) a description of the interfaces, including the type of data transfer, the valid data range and the
checking for valid data.
c) full source code listings, as hard copy or in machine-readable form (e.g. ASCII-code), including all global
and local variables, constants and labels used, and sufficient comment for the program flow to be
recognized;
d) details of any software tools used in the design and implementation phase (e.g. CASE-tools, compilers).
4.11.3 Software design
In order to ensure the reliability of the detector, the following requirements for software design shall apply:
a) the software shall have a modular structure;
b) the design of the interfaces for manually and automatically generated data shall not permit invalid data to
cause error in the program operation;
c) the software shall be designed to avoid the occurrence of deadlock of the program flow.
4.11.4 The storage of programs and data
The program necessary to comply with this standard and any preset data, such as manufacturer's settings,
shall be held in non-volatile memory. Writing to areas of memory containing this program and data shall only
be possible by the use of some special tool or code and shall not be possible during normal operation of the
detector.
Site-specific data shall be held in memory which will retain data for at least two weeks without external power
to the detector, unless provision is made for the automatic renewal of such data, following loss of power,
within 1 h of power being restored.
5. Tests
5.1 General
5.1.1 Atmospheric conditions for tests
Unless otherwise stated in a test procedure, the testing shall be carried out after the test specimen has been
allowed to stabilise in the standard atmospheric conditions for testing as described in
IEC 60068-1:1988+A1:1992 as follows:
a) temperature:  (15 to 35) °C;
b) relative humidity: (25 to 75) %;
c) air pressure: (86 to 106) kPa.
NOTE If variations in these parameters have a significant effect on a measurement, then such variations should be kept
to a minimum during a series of measurements carried out as part of one test on one specimen.
5.1.2 Operating conditions for tests
If a test method requires a specimen to be operational, then the specimen shall be connected to suitable
supply and monitoring equipment with characteristics as required by the manufacturer's data. Unless
otherwise specified in the test method, the supply parameters applied to the specimen shall be set within the
manufacturer's specified range(s) and shall remain substantially constant throughout the tests. The value
9

---------------------- Page: 11 ----------------------
oSIST prEN 54-15:2006
prEN 54-15:2006 (E)
chosen for each parameter shall normally be the nominal value, or the mean of the specified range. If a test
procedure requires a specimen to be monitored to detect any alarm or fault signals, then connections shall be
made to any necessary ancillary devices (e.g. through wiring to an end-of-line device for conventional
detectors) to allow a fault signal to be recognised.
NOTE The details of the supply and monitoring equipment and the alarm criteria used should be given in the test
report.
5.1.3 Mounting arrangements
The specimen shall be mounted by its normal means of attachment in accordance with the manufacturer's
instructions. If these instructions describe more than one method of mounting then the method considered to
be most unfavourable shall be chosen for each test.
5.1.4 Tolerances
Unless otherwise stated, the tolerances for the environmental test parameters shall be as given in the basic
reference standards for the test (e.g. the relevant part of IEC 60068).
If a requirement or test procedure does not specify a tolerance or deviation limits, then deviation limits of
± 5 % shall be applied.
5.1.5 Measurement of response threshold values
5.1.5.1 Fire test room
The measurement of response threshold values shall be conducted in a rectangular room with a flat horizontal
ceiling, and the following dimensions:
Length: 9 m to 11 m;
Width: 6 m to 8 m;
Height: 3,8 m to 4,2 m.
The fire test room shall be equipped with at least the following measuring instruments arranged as indicated in
Annex B:
Measuring ionisation chamber (MIC);
Obscuration meter;
Temperature probe with a time constant not greater than 2 s, when measured in air with a mass flow
-1
equivalent to (0,8 ± 0,1) ms at 25°C.

5.1.5.2 Test fires
The specimens shall be subjected to the test fires specified in the test procedure (see Annex C to Annex H).
The type, quantity and arrangement of the fuel and the method of ignition are described in Annex C to
Annex H, for each test fire, along with the end of test condition and the required profile curve limits.
In order to be a valid test fire, the development of the fire shall be such that the profile curves of m against y
and m against time fall within the specified limits, up to the time when all of
