The work of preparing International Standards is nor
25、mally 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
26、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 t
27、he 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
28、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 .i

ISO 2017 All rights reserved vii ISO/TS 7240-29:2017(E) Introduction A video fire detection system differs from some point-type detectors (e.g. ISO 7240-6, ISO 7240-7 ) in that
32、 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 pres
33、ence 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 a
34、nd 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 equi
35、pment 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 dete
36、ction 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
37、 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.viii ISO 2017 All rights reserved Fire detection and alarm systems Part 29: Video fire detectors 1 Scope This document specif
38、ies 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, this d
39、ocument 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
