Overview

EN 54-29:2015 is a CEN European Standard for multi-sensor point fire detectors that combine smoke and heat sensing in a single enclosure. It specifies the requirements, test methods and performance criteria for these detectors when used in building fire detection and fire alarm systems (see EN 54-1:2011). The standard also covers the Assessment and Verification of Constancy of Performance (AVCP) and factory production control needed for certification. Note: detectors containing radioactive materials are subject to national radiation protection rules and are not defined by this standard.

Key topics and technical requirements

• Detector type and scope: Point-type multi-sensor devices incorporating at least one optical or ionization smoke sensor plus at least one heat sensor. Detectors with special risk‑specific characteristics or additional functions beyond the standard’s tests are excluded.
• Performance criteria (Clause 4 / 5): Includes nominal activation conditions / sensitivity, response to slowly developing fires, repeatability, directional dependence, lower heat response limit, and overall fire sensitivity determined by the combination of smoke and heat signals.
• Operational reliability: Requirements for ancillary device connections, monitoring of detachable detectors, manufacturer and on‑site adjustments, protection against ingress, and software‑controlled detectors.
• Durability and environmental resistance: Tests for temperature, humidity, shock & vibration, electrical stability and resistance to chemical agents (durability of nominal activation conditions).
• Test methods and apparatus: Normative test setups including smoke tunnels, heat tunnels, fire test room, standard fire forms (e.g., open wood fire, smouldering wood) and instruments for measuring smoke/heat response (annexes A–I).
• AVCP and production control (Clause 6): Type testing, sampling, test reporting, Factory Production Control (FPC), continuous surveillance and procedures for design/production modifications.
• Marking, classification and packaging: Rules for designation and labelling to ensure correct application and traceability.

Introduction
Multi-sensor fire detectors combining smoke and heat sensors complying with this document are general
purpose fire detectors. Multi-sensor fire detectors can be used to achieve
— a high stability against deceptive phenomena,
— a response to a broad range of fires.
Compared to the standards for single phenomenon detectors, additional environmental tests were included to
demonstrate a higher stability.
The response to a broad range of fires is shown by including the test fires TF1 and TF8 in addition to the test
fires TF2 to TF5 which are used for detectors complying with EN 54-7.
The performance of single sensor components of a multi-sensor fire detector need not comply with the
standards for single phenomena fire detectors (EN 54-5, EN 54-7) however the combined performance does
need to meet the requirements of this standard.
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 54-1:2011), incorporating
in one mechanical enclosure at least one optical or ionization smoke sensor and at least one heat sensor. The
overall fire detection performance is determined utilizing the combination of the detected phenomena.
This European Standard provides for the assessment and verification of constancy of performance (AVCP) of
point detectors using a combination of smoke and heat sensors to this European Standard.
Point detectors using a combination of smoke and heat sensors having special characteristics suitable for the
detection of specific fire risks are not covered by this European Standard. The performance requirements for
any additional functions are beyond the scope of this European Standard (e.g. additional features or
enhanced functionality for which this European Standard does not define a test or assessment method).
NOTE 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 European Standard.

memory element which does not require the presence of an energy source for the retention of its content
3.2
site specific data
alterable data required for the detector to operate in a defined detector configuration
3.3
smoke response value
aerosol density in the proximity of a test specimen at the moment that it generates a reference signal in a
smoke tunnel
3.4

4 Requirements
4.1 General
In order to comply with this standard, the detector shall meet the requirements of Clause 4, which shall be
verified by visual inspection, engineering assessment or shall be tested as described in Clause 5 and shall
meet the requirements of the tests.
4.2 Nominal activation conditions/sensitivity
4.2.1 Individual alarm indication
The 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 when assessed as described in 5.2.1.
NOTE The alarm condition is reset manually at the control and indicating equipment (see EN 54–2:1997 as amended
by EN 54–2:1997/A1:2006).
4.2.2 Response to slowly developing fires
The detector may incorporate provision for “drift compensation”, for example to compensate for sensor drift
due to the build up of dirt in the detector, If such drift compensation is included, then it shall not lead to a
significant reduction in the detector's sensitivity to slowly developing fires when assessed as specified in 5.2.2.
4.2.3 Repeatability of smoke response
The detector shall have stable behaviour with respect to its sensitivity to smoke after a number of alarm
conditions. To confirm this, the detector shall be assessed in accordance with 5.2.3.
4.2.4 Directional dependence of smoke response
The sensitivity of the detector to smoke shall not be unduly dependent on the direction of airflow around it. To
confirm this, the detector shall be assessed in accordance with 5.2.4.
4.2.5 Directional dependence of heat response
The heat sensitivity of the detector shall not be unduly dependent on the direction of airflow around it. To
confirm this, the detector shall be assessed in accordance with 5.2.5.
4.2.6 Lower limit of heat response
The detector shall not be more sensitive to heat alone, without the presence of smoke, than is permitted in
EN 54-5:2000 as amended by EN 54-5:2000/A1:2002. To confirm this, the detector shall be assessed in
accordance with 5.2.6.
4.2.7 Reproducibility of smoke response
The sensitivity of the detector to smoke shall not vary unduly from specimen to specimen. To confirm this, the
detector shall be assessed in accordance with 5.2.7.
4.2.8 Reproducibility of heat response
The heat sensitivity of the detector shall not vary unduly from specimen to specimen. To confirm this, the
detector shall be assessed in accordance with 5.2.8.
4.2.9 Air movement
The sensitivity of the detector shall not be unduly affected by the rate of the airflow and that it is not unduly
prone to false alarms in draughts or in short gusts. To confirm this, the detector shall be assessed in
accordance with 5.2.9.
4.2.10 Dazzling
The sensitivity of the detector shall not be unduly influenced by the close proximity of artificial light sources. To
confirm this, the detector shall be assessed in accordance with 5.2.10. This test is only applicable to detectors
using optical smoke sensors, as ionization chamber detectors are considered unlikely to be influenced.
4.3 Operational reliability
4.3.1 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.
4.3.2 Monitoring of detachable detectors
For detachable detectors, 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.
4.3.3 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.
4.3.4 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.
These adjustments may be carried out at the detector or at the control and indicating equipment.
4.3.5 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 smoke
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.
4.3.6 Software controlled detectors
4.3.6.1 General
For detectors which rely on software control in order to fulfil the requirements of this standard, the
requirements of 4.3.6.2, 4.3.6.3 and 4.3.6.4 shall be met.
4.3.6.2 Software documentation
4.3.6.2.1 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);
c) a designation, by which the software and its version can be uniquely identified.
4.3.6.2.2 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
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).
4.3.6.3 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.
4.3.6.4 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.
4.4 Tolerance to supply parameters
4.4.1 Variation in supply parameters
Within the specified range(s) of the supply parameters, the sensitivity of the detector shall not be unduly
dependent on these parameters (e.g. voltage). To confirm this, the detector shall be assessed in accordance
with 5.4.1.
4.5 Performance parameters under fire conditions
4.5.1 Fire sensitivity
The detector shall have adequate sensitivity to incipient type fires that may occur in buildings. To confirm this,
the detector shall be assessed in accordance with 5.5.1.
4.6 Durability of nominal activation conditions/sensitivity
4.6.1 Temperature resistance
4.6.1.1 Dry heat (operational)
The detector shall function correctly at high ambient temperatures. To confirm this, the detector shall be
assessed in accordance with 5.6.1.1.
4.6.1.2 Cold (operational)
The detector shall function correctly at low ambient temperatures. To confirm this, the detector shall be
assessed in accordance with 5.6.1.2.
4.6.2 Humidity resistance
4.6.2.1 Damp heat, cyclic (operational)
The detector shall function correctly at a high level of relative humidity with short period of condensation. To
confirm this, the detector shall be assessed in ac
