Fire detection and alarm systems - Part 29: Video fire detectors

ISO/TS 7240-29:2017 specifies requirements, test methods and performance criteria for video fire detectors (VFD), 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, ISO/TS 7240-29:2017 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 ISO/TS 7240-29:2017 does not define a test or assessment method) are beyond the scope of ISO/TS 7240-29:2017.

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
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 might 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 sense 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.

Note 2 to entry: The response threshold value can depend on signal processing in the detector and in fire
detection control and indicating equipment.

4 Requirements
4.1 Compliance
In order to comply with this document, the VFD shall meet the following requirements:
a) comply with the requirements of Clause 4, which shall be verified by visual inspection or
engineering assessment;
b) be tested as specified in Clause 5, meeting the requirements of the tests;
c) be marked in accordance with Clause 6 and be accompanied by the documentation specified in
Clause 7, which shall be verified by visual inspection.
4.2 Fire phenomena
The manufacturer shall declare, in the data presented in Clause 7, a phenomenon of fire in Table 1 to
which the VFD is designed to respond.
Table 1 — Fire phenomena types
Type Fire phenomena
A Smoke
B Flame
AB Smoke and Flame
NOTE 1 Type AB VFD can detect flame emitted by test fire for type A VFD, and can also detect smoke from a
type B test fire. Thus type AB VFD is NOT required to detect the smoke emitted by test fire for type A but it can
signal an alarm to all the test fires.
NOTE 2 VFD can have two types (i.e. Type A and B) if the flame detection and smoke detection algorithms
within the VFD can be separately activated/monitored.
4.3 Immunity to unwanted alarms
4.3.1 Detectors shall be immune from phenomena that can cause unwanted alarms.
4.3.2 Optional tests shall be performed where the manufacturer claims immunity to the phenomena.
4.4 Detection range
The manufacturer shall declare the ranges at which the VFD shall detect a fire in the data supplied in
Clause 7.
4.5 Camera lenses
4.5.1 VFD may use interchangeable or variable focal length lenses.
4.5.2 A change of focus of the camera lens that prevents the VFD from detecting a fire shall cause a
fault signal.
4.6 Camera lens monitoring
4.6.1
