Foreword
This document (prEN 54-30:2009) has been prepared by Technical Committee CEN/TC 72 “Fire detection
and fire alarm systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
Introduction
Carbon monoxide (CO) is a product of the incomplete combustion of carbon-based materials. CO fire
detectors can react promptly to smouldering fires involving carbonaceous materials because CO does not
depend solely on convection, but also moves by diffusion. CO fire detectors might be better suited to
applications where other fire detection techniques are prone to false alarms, for example due to dust, steam
and cooking vapours. Detectors based on the use of CO sensors alone are covered by EN 54-26.
Some fires may not produce a sufficient amount of CO to trigger an alarm condition from a detector complying
with EN 54-26. These are typically free-burning, open, well ventilated fires. The inclusion of heat sensing
combined with CO sensing can increase the sensitivity of such a detector to these types of fires.
A number of different methods for sensing CO are suitable. However, most sensors will also be influenced by
other gases and phenomena. Tests have therefore been included in the test schedule to assess cross-
sensitivity to substances normally present in the service environment that may affect the performance of the
detector.
Test Fires TF2, TF3, TF4 and TF5 from EN 54-7 have been included to verify the detection performance. TF4
and TF5 specifically demonstrate the influence of the heat sensor(s). For these Test Fires, the CO level and,
where applicable, the temperature is used as test validity criteria.
Detectors may have modes of operation, in which only one fire phenomenon is evaluated. This standard does
not include tests for additional alarm outputs corresponding to the sensing of only one fire phenomenon.
Reference should be made to other parts of EN 54 which may cover such modes of operation or outputs.
prEN 54-30:2009 (E)
1 Scope
This European Standard 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), incorporating in one
mechanical enclosure at least one carbon monoxide sensor and at least one heat sensor. The overall fire
detection performance is determined utilizing the combination of the detected phenomena.
Multi-sensor fire detectors having special characteristics suitable for the detection of specific fire risks are not
covered by this standard. The performance requirements for any additional functions are beyond the scope of
this standard (e.g. additional features or enhanced functionality for which this standard does not define a test
or assessment method).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 54-1 and the following apply.
3.1
CO response threshold value
CO concentration in the proximity of the specimen at the moment that it generates an alarm signal, when
tested as described in 5.1.5
NOTE The response threshold value may depend on signal processing in the detector and in the control and
indicating equipment
3.2
rate-sensitive
behaviour of a detector that depends on the rate of change of CO concentration
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, by which the individual detector that
released an alarm, can be identified, until the alarm condition is reset. 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.
prEN 54-30:2009 (E)
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:
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 Rate-sensitive CO response
The CO response threshold value of the detector may depend on the rate of change of CO concentration in
the vicinity of the detector. Such behaviour may be incorporated in the detector design to improve the
discrimination between ambient CO levels and those generated by a fire. If such rate sensitive behaviour is
included then it shall not lead to a significant reduction in the detector’s sensitivity to fires, nor to a significant
increase in the probability of false alarm.
Since it is not practical to make tests with all possible rates of increase in CO concentration, an assessment of
the detector's rate sensitivity 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 for
constant temperatures between the lower and upper limits of the temperature range as defined by the
manufacturer:
a) for any rate of increase in CO concentration less than 1 µl/l per minute the detector will signal an alarm
condition before the CO concentration reaches 60 µl/l, and;
b) the detector does not signal an alarm condition when subjected to a step change in CO concentration of
10 µl/l, superimposed on a background level between 0 and 3 µl/l.
4.8 Position of the heat sensors
Detector shall be constructed such that, at least, part of the heat sensing element(s) of its heat sensor(s) shall
not be less than 15 mm from the mounting surface of the detector.
4.9 Marking
Each detector shall be clearly marked with the following information:
a) the number and date of this standard (i.e. EN 54-30:xxxx);
b) the name or trademark of the manufacturer or supplier;
c) the model designation (type or number);
d) the wiring terminal designations;
prEN 54-30:2009 (E)
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.
The marking shall be visible during installation of the detector and shall be accessible during maintenance.
The marking 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 this data is not supplied with each detector, reference to the
appropriate data sheet shall be given on, or with each detector.
NOTE Additional information may be required by organisations certifying that detectors produced by a manufacturer
conform to the requirements of this standard.
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 Design overview
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);
1)
To enable correct operation of the detectors, this 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.
prEN 54-30:2009 (E)
c) a designation, by which the software and its version can be uniquely identified.
4.11.3 Design detail
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;
3) a description of the interfaces, including the type of data transfer, the valid data range and the

4.11.5 The storage of programs and data
The program necessary to comply with this standard and any pre-set 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 Test methods
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 stabilize in the standard atmospheric conditions for testing as described in EN 60068-1:1994 as
follows:
prEN 54-30:2009 (E)
temperature: (15 to 35) °C;
relative humidity: (25 to 75) %;
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.
The ambient concentration of CO shall not exceed 3 µl/l.
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
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 and in its normal orientation in
accordance with the manufacturer's instructions. If these instructions describe more than one method of
mounting, or more than one acceptable orientation, 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 EN 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 CO response threshold value
The specimen, for which the CO response threshold value is to be measured, shall be installed in the gas test
chamber, described in Annex A, in its normal operating position, by its normal means of attachment. The
orientation of the specimen, relative to the direction of airflow, shall be the least sensitive orientation, as
determined in the directional dependence test, unless otherwise specified in the test procedure.
Before commencing each measurement, the gas test chamber shall be purged with clean air to ensure that
the concentration of CO in the gas test chamber is less than 1,5 µl/l.
The air velocity in the proximity of the specimen shall be (0,2 ± 0,04) m/s during the measurement, unless
otherwise specified in the test procedure.
Unless otherwise specified in the test procedure, the air temperature in the gas test chamber shall be
(23 ± 5)°C and shall not vary by more than 5 K for all the measurements.
The specimen shall be connected to its supply and monitoring equipment as described in 5.1.2, and shall be
allowed to stabilise for a period of at least 15 min, unless otherwise specified by the manufacturer.
prEN 54-30:2009 (E)
CO shall be introduced into the gas test chamber such that the rate of increase of CO concentration is
between 1 µl/l per minute and 6 µl/l per minute, unless otherwise specified in the test procedure. For detectors
with a rate sensitive behaviour, the manufacturer may specify a rate of increase within this range to ensure
that the measured CO response threshold value is representative of the static CO response threshold value of
the detector.
The rate of increase in CO concentration shall be similar for all measurements on a particular detector type.
The CO concentration at the moment that the specimen gives an alarm shall be recorded as S (µl/l). This shall
be taken as the CO response threshold value.
5.1.6 Measurement of heat response threshold value
Where detectors comply with EN 54-5:2000 as amended by EN 54-5:2000/A1:2002, the response times
measured in those tests may be used as the heat response values for the purposes of this standard.
The specimen for which the temperature response value is to be measured shall be installed in a heat tunnel,
as specified in Annex E, in its normal operating position, by its normal means of attachment. The orientation of
the specimen, relative to the direction of airflow, shall be the least sensitive one, as determined in the
directional dependence test (5.4), unless otherwise specified in the test procedure.
The specimen shall be connected to its supply and indicating equipment as specified in 5.1.2, and allow it to
stabilize for at least 15 min.
Before the test, the temperature of the air stream and the specimen shall be stabilized to (25 ± 2) °C. The air
stream shall be maintained at a constant mass flow equivalent to a velocity of (0,8 ± 0,1) m/s at 25 °C.
The air temperature shall be increased at a rate specified in the test until either an alarm signal has been
generated or a designated signal specified by the manufacturer is produced by the heat sensor. This signal
shall be routed via any applicable amplification circuit and algorithm hardware.
NOTE If the detector is not capable of giving an alarm signal from heat alone, it will be necessary for the
manufacturer to provide special means by which the designated heat response signal can be evaluated. For example, it
may be acceptable to provide a supplementary output that varies with temperature, or specially modified software to
indicate when the air temperature has caused an internal threshold to be reached. In such cases the special means
should preferably be chosen such that the nominal heat response value corresponds to a response time between the
minimum and maximum times given in Table 4 of EN 54-5:2000 as amended by EN 54-5:2000/A1:2002-5 for a class A2
detector.
The heat response value shall be assessed as the time taken from the start of the temperature increase to the
point at which the heat response signal specified by the manufacturer is produced, or the detector gives an
alarm signal.
The measured heat response value shall be recorded as T.
5.1.7 Provision for tests
The following shall be provided for testing compliance with this standard:
a) for detachable detectors; twenty six detector heads and bases; for non-detachable detectors; twenty six
specimens.
b) the data required in 4.10.
NOTE 1 Detachable detectors comprise at least two parts; a base (socket) and a head (body). If the specimens are
detachable detectors, then the two, or more, parts together are regarded as a complete detector.
The specimens submitted shall be deemed representative of the normal production with regard to their
construction and calibration.
prEN 54-30:2009 (E)
NOTE 2 This implies that the mean response threshold value of the twenty six specimens found in the reproducibility
tests, 5.6 and 5.7 should also represent the production mean, and that the limits specified in the reproducibility test should
also be applicable to the full sensitivity range anticipated during production.
5.1.8 Test schedule
The specimens shall be tested according to the following test schedule (see Table 1). After the reproducibility
of CO response test, the four least sensitive specimens (i.e. those with the highest CO response thresholds)
shall be numbered 23 to 26, and the others shall be numbered 1 to 22 arbitrarily.

In the interests of test economy, it is permitted to use the same specimen for more than one EMC test. In that case, intermediate
functional test(s) on the specimen(s) used for more than one test can be deleted, and the functional test conducted at the end of the
sequence of tests. However it should be noted that in the event of a failure, it may not be possible to identify which test exposure
caused the failure (see Clause 4 of EN 50130-4:1995 as amended by EN 54130-4:1995/A1:1998 and EN 54130-4:1995/A2:2003).
