Video Image Smoke Detectors for Automatic Fire Alarm Signaling
|Publication Date:||1 December 2011|
This standard describes performance requirements for Video Image Fire Detectors (VIFD), and Video Image Fire Detection Systems (VIFDS) for Automatic Fire Alarm Signaling for the protection of occupants, building space, structure, area, or object and designed to detect products of combustion in a specific location.
This standard applies to Video Image Fire Detectors intended for use in fire alarm signaling or extinguishing system applications that operate via the image within the field of view area as defined by the camera. This standard employs test protocol dependent on the installation and operating instructions provided by the manufacturer. This information assists in defining the limits for the overall application and Approved use of the product
A Video Image Fire Detector is a combination Video Image Smoke and Flame Detector (VIS&FD) and will be examined in accordance with this standard and will be listed in the Approval Guide as a Video Image Fire Detector.
Other types of commercially available video image detectors (such as Flame only) may not be applicable to the test protocol described in this document.
These detectors are intended to be installed in accordance with the manufacturer's installation instructions and in accordance with ANSI/NFPA 72 The National Fire Alarm Code and in a manner acceptable to the local Authority Having Jurisdiction. Other NFPA Standards may apply, such as those covering extinguishing system applications.
The Video Image Fire Detector is not intended to be a direct replacement for standard open area protection, but does offer detection capabilities not possible with conventional detectors. Special consideration must be given to Video Image Fire Detectors regarding the overall system's sensitivity and special care required to reduce the possibility of false alarms.
