ISO 7240-13:2005

Fire detection and alarm systems — Part 13: Compatibility assessment of system components

ISO 7240-13:2005 specifies the requirements for compatibility and connectability assessment of system components that either comply with the requirements of ISO 7240 or with a manufacturer's specification where there is no ISO 7240 International Standard. ISO 7240-13:2005 includes only system requirements when these are necessary for compatibility assessment. ISO 7240-13:2005 also specifies requirements for the integrity of the fire detection and fire alarm system when connected to other systems. ISO 7240-13:2005 is applicable to systems where the components are connected to control-and-indicating equipment (c.i.e.) and where the components are interconnected by electrical wires. For fire detection and fire alarm systems using other means of interconnection (for example optical fibre or radio frequency links), ISO 7240-13:2005 may be used as guidance. ISO 7240-13:2005 does not specify the manner in which the system is designed, installed and used in any particular application.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7240-13 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 3, Fire detection and alarm systems.
ISO 7240 consists of the following parts, under the general title Fire detection and alarm systems:

ISO 7240-13:2005(E)
Introduction
The fire detection function is to detect at the earliest practicable moment, and to give signals and indications
so that appropriate action can be taken.
The fire alarm function is at least to give audible and/or visible signals to the occupants of a building who may
be at risk from fire.
A fire detection and alarm system combines the functions of detection and alarm in a single system and
typically consists of a number of inter-linked components including automatic fire detectors, manual call points
and alarm sounders. These components are connected to control and indicating equipment by means of one
or more transmission paths. All system components, including the control and indicating equipment, are also
directly or indirectly connected to a power supply.
ISO 7240-1 provides additional information about the components performing those functions that are listed in
Annex A of this part of ISO 7240.
A fire protection and/or building management systems or remote fault and fire alarm monitoring stations that
are linked to a fire detection and alarm system, are not considered part of the fire detection and alarm system.
All the components constituting the fire detection and alarm system need to be compatible or connectable and
requirements relating to the performance of the overall system need to be fulfilled.
Differentiation is made between components classified as components type 1 and other components
classified as components type 2.
This part of ISO 7240 recognizes that it is not practical to assess the compatibility or connectability of
components in all possible configurations. Methods of assessment are specified to reach an acceptable
degree of confidence within pre-determined operational and environmental conditions.
National application guidelines (also known as codes of practice) also contain system requirements. Suppliers
of components shall ensure that they
 meet the requirements of this part of ISO 7240;
 meet the requirements of the relevant part of ISO 7240; and
 meet the requirements of the application guidelines of the countries where the components are intended
to be placed on the market.
System requirements are also included for those fire detection and alarm systems which are linked to fire
protection and/or other systems (for example: building management systems).

Fire detection and alarm systems —
Part 13:
Compatibility assessment of system components
1 Scope
This part of ISO 7240 specifies the requirements for compatibility and connectability assessment of system
components that either comply with the requirements of ISO 7240 or with a manufacturer’s specification
where there is no ISO 7240 International Standard. This part of ISO 7240 includes only system requirements
when these are necessary for compatibility assessment.
This part of ISO 7240 also specifies requirements for the integrity of the fire detection and fire alarm system
when connected to other systems.
This part of ISO 7240 does not specify the manner in which the system is designed, installed and used in any
particular application.
This part of ISO 7240 is applicable to systems where the components are connected to control-and-indicating
equipment (c.i.e.) and where the components are interconnected by electrical wires. For fire detection and fire
alarm systems using other means of interconnection (for example optical fibre or radio frequency links), this
part of ISO 7240 may be used as guidance.
NOTE Other International Standards are expected to cover the requirements of the other systems to which the fire
detection and fire alarm system may be connected.

the manufacturer and within the limits given in the relevant parts of ISO 7240.
6.2.2 Test schedule
6.2.2.1 A test schedule shall be drawn up, in order to check if the components exercise their functions
(fire alarm, fault warning, disabled condition, test condition etc.) correctly within the specifications given by the
manufacturer and the relevant part of ISO 7240. The components shall be fully operational.
6.2.2.2 During testing, implemented functions of the f.d.a.s. shall be activated in sequence (except when

b) the maximum supply voltage of the c.i.e. with the minimum load on all transmission paths.
NOTE 1 The load includes the number of components and the length of the cables.
NOTE 2 The maximum load on all transmission paths means that at least one transmission path is fully loaded. The
other transmission path(s) can either be fully loaded or have their load simulated. Where this is impractical, especially in
networked or hierarchic systems, a manufacturers declaration might also be required.
