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).
Any trade name used in this document is information given for the convenience of users and does not

Introduction
The installation of a video fire detection system (VFDS) can only be successfully accomplished if the
following conditions are fulfilled:
— materials are of a suitable quality;
— special knowledge in the field of video fire detection (VFD) is implemented;
— skilled personnel carry out the work.
Although the quality of the material can be ensured by adherence to applicable standards and quality
audits, the overall effectiveness of an installation depends widely on the quality of work, the experience
of the designer and installer, and regular service.
This document has been prepared by ISO/TC 21/SC 3. A number of existing national codes and
standards were reviewed during the preparation of this document. As VFD technology is significantly
different from conventional fire detection technology, different considerations need to be addressed and
therefore a document specifying the installation of VFDSs has been developed. While specific to VFDSs,
this document has the same objective of early fire detection as ISO 7240-7. This document specifies the
minimum requirements for fire detection installation using equipment conforming ISO/TS 7240-29.

TECHNICAL SPECIFICATION ISO/TS 7240-30:2022(E)
Fire detection and alarm systems —
Part 30:
Design, installation, commissioning and service of video
fire detector systems
1 Scope
This document specifies the design, installation, commissioning and service requirements for video
fire detector systems (VFDS; see ISO/TS 7240-29), which are primarily intended to provide early
detection of fire within one or more specified indoor areas for the protection of lives and equipment.
The VFDS can also serve to protect from specific defined risks. The VFDS can be an independent fire
detection system or can be used in conjunction with a fire detection and alarm system (FDAS; see
ISO 7240-1:2014, Figure 1).

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 7240-1 and the following
apply.

3.1.1
alarm zone
geographic subdivision of the premises in which one or more alarm devices are installed and for which
a common zonal alarm indication is provided
3.1.2
detection zone
geographic subdivision of the premises in which one or more points are installed and for which a
common zonal detection indication is provided
3.1.3
field of view
image captured by the video fire detector
Note 1 to entry: Field of view is a 2D projection/representation of the objects within a 3D rectangular pyramid.
3.1.4
active field of view
area in field of view in which smoke and/or flame can be detected by the video fire detector
Note 1 to entry: The active field of view takes into consideration any borders to the field of view where detection
is not effective and areas within the field of view deliberately masked to avoid nuisance alarms.
3.1.5
illuminator
light source, internal or external to the video fire detector that assists the equipment to operate in low
ambient light conditions
3.1.6
monitored volume
3-dimensional space within a protected space that is visible in the active field of view of the video fire
detector such that smoke/flame occurring in (or around) that space is detected

the video fire detector and any obstacles within the space which can potentially obscure the view.

4 Equipment and material
4.1 Quality of components
Components used as part of the VFDS shall be designed and manufactured in accordance with a
recognized quality system.
The equipment manufacturer shall make available to the VFDS designer information about the
manufacturer’s quality assurance system to satisfy the designer that the components selected for the
VFDS are suitable for the application.
4.2 Standards
Equipment used in the VFDS shall conform to the relevant part of the ISO 7240 series or other
International Standards, as appropriate. The testing supporting such conformity shall be performed in
a testing laboratory that meets the requirements of ISO/IEC 17025.
Note 1 Certification can be used to demonstrate conformity of the equipment to the relevant standard.
Note 2 Accreditation of the testing laboratory for the testing of equipment in accordance with the relevant
standard can be used to demonstrate competence of the laboratory to perform the specific tests. Where
assessment has not been made by an independent party, the designer identifies the components and describes
why assessment has not been undertaken.
4.3 Environmental requirements
Each item of equipment shall be installed within an environment for which it has been certified.
Additional requirements may apply in special cases, e.g.:
— potentially explosive atmospheres;
— special electromagnetic compatibility (EMC) requirements.
