ISO 7240-13:2020(E)
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 be fulfilled.
Differentiation is made between components classified as components type 1 and other components,
classified as components type 2.
As the possible configurations of fire detection and alarm systems are unlimited, the assessment is
only carried out on the configuration(s) declared by the applicant.
This document 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.
System requirements are also included for fire detection and alarm systems which are linked to fire
protection systems and/or other systems (for example: fire suppression and building management
systems).
The intended use of this document is to demonstrate the compatibility and connectability of
components, even if they are not defined by an ISO standard.
