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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
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 first edition of ISO 7240-29 cancels and replaces the first edition of ISO/TS 7240-29:2017, which has
been technically revised.
The main changes are as follows:
— additional detail has been added to the requirements for the response threshold value (RTV) test for
Type A and AB video smoke detectors;
— the RTV test has been eliminated for Type B detectors;
— requirements have been provided for controllers that are and are not in the same environment as the
cameras;
— the dark and light background during fire tests can now be replaced with high and low illumination of
the background;
— the non-uniform illumination test has been corrected to remove references to alternate background
screens and related diagrams have been corrected;
— the requirement to operationally test the detector during hot and cold conditioning tests has been
removed;
— the operational impact test has been modified to reference IEC 62262;
— the operational vibration test has been eliminated;
— a vibration endurance test has been added for the controller.

Introduction
A video fire detection system differs from some point-type detectors (e.g. ISO 7240-6, ISO 7240-7) in that the
detection is performed remotely from the actual fire and therefore does not involve sensor contact with the
products of combustion. The fire detection is based on mathematical algorithm analysis of a video image.
The video image from a camera can be processed by software to determine the presence of smoke and/or
flame (depending on the capability of the system) which is visible in the image.
Video fire detectors consist of three elements: a sensor, an image processor and a transmission path between
the sensor and image processor. The elements can be in a single cabinet, or the sensor and processor can be
in separate cabinets, interconnected by a transmission path.
The processor incorporates an alarm and fault signalling interface to connect to a compatible fire detection
control and indicating equipment transmission path.
Two types of detectors are specified to differentiate equipment that senses smoke or flame. A single detector
can also sense both smoke and flame.
Two enclosure protection ratings are specified for dust and water ingress protection.
Three environmental temperature ranges are specified, for detectors suitable for installation indoors or
outdoors.
A fire detection and alarm system is required to function satisfactorily not only in the event of fire, but also
during and after exposure to conditions likely to be met in practice, including corrosion, vibration, direct
impact, indirect shock and electromagnetic interference. Tests are intended to assess the performance of
the video fire detectors under such conditions.
This document is not intended to place any other restrictions on the design and construction of such
detectors.

Fire detection and alarm systems —
Part 29:
Video fire detectors
1 Scope
This document specifies requirements, test methods and performance criteria for video fire detectors
(VFDs), which operate in the visible spectrum, for use in fire detection and alarm systems installed in and
around buildings (see ISO 7240-1). For the testing of other types of VFD working on different principles, this
document can be used only for guidance.
Detectors developed for the protection of specific risks that incorporate special characteristics (including
additional features or enhanced functionality for which this document does not define a test or assessment
method) are beyond the scope of this document.
