Fire detection and alarm systems — Part 13: Compatibility assessment of system components
This document specifies the requirements for compatibility and connectability assessment of the components of fire detection and alarm systems, fire protection systems and voice alarm systems. This document only includes system requirements when these are necessary for compatibility assessment. This document also specifies requirements for the integrity of the fire detection and fire alarm system when connected to other systems. This document does not specify the manner in which the system is designed, installed and used in any particular application. This document does not cover components or functions which are not included in the fire detection and alarm systems (FDAS), such as functions performed by a building management system. Methods of assessment are specified to permit an acceptable degree of confidence within predetermined operational and environmental conditions to be achieved. The requirements for the transmission path used for a distributed function are covered by a relevant ISO standard and not by this document. This document is applicable to systems where the components are connected to control-and-indicating equipment (CIE) and where the components are interconnected by electrical wires or optical fibre or by radio frequency links or by any combination of these. ISO 7240-25 provides additional information and requirements about systems using radio frequency links. NOTE Other International Standards are expected to cover the requirements of other systems to which the fire detection and fire alarm system is connected.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

This document was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire
fighting, Subcommittee SC 3, Fire detection and alarm systems.
This second edition cancels and replaces the first edition (ISO 7240-13:2005), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— This edition takes into account new techniques in communication and the availability of new
technologies and concepts.
— This edition is applicable to electrical wires, optical fibre or radio frequency connections. The
previous edition was only applicable to electrical wires.
— Clarification introduced that it is possible to use this document to establish compatibility with fire
protection equipment such as sprinkler flow switches and electrically activated sprinkler heads.
— Levels (field, control and management) and a network transmission path for the basis of system
configuration introduced.
— References to EN standards have been replaced with the appropriate IEC standard references.
— Introduction of Annex A, Example of levels used in FDAS.
— Introduction of Annex B, Classification of functions of the FDAS.
— Introduction of Annex C, Example methodology for theoretical analysis.
— Introduction of Annex D, Software design documentation.
— Introduction of Annex E, Flowchart for assessment of compatibility/connectability.
— Introduction of Annex F, previously Annex A, upgraded to the latest fire detection and alarm system
functions diagram from ISO 7240-1.

Introduction
The purpose of fire detection is to detect a fire at the earliest practicable moment and to give signals
and indications so that appropriate action can be taken.
The purpose of a fire alarm is, at a minimum, 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 including voice alarm systems 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 devices. 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.
A separate voice alarm system can be assessed for compatibility and connectability independently of
the fire detection and alarm system.
ISO 7240-1 provides additional information about the components performing these functions, listed in
Annex F of this document.
A fire protection system and/or building management system, 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.
It is necessary for all of the components constituting the fire detection and alarm system to be
compatible or connectable and it is necessary that requirements relating to the performance of the
overall system
