Abstract

Given the range of environmental and system variables that can impact a design, it is recommended that a systematic test program be conducted to quantify the effect on VID system performance relative to key variables. With the relatively recent development and growing use of flame and VID systems, there is a general need by end-users and fire protection system designers to have documented, quantitative performance capabilities. These capabilities should include both fire detection and false/nuisance alarm discrimination. One area of concern is detection relative to obstructions between the flame/smoke and the camera. There is a lack of data and testing of fire detection capability (particularly for flame detection) for fires that are partially obstructed in the field of view or flames impinging on objects. In these scenarios, flames will be distorted or discontinuous in the video image compared to fires burning in the open. It is also recommended that systems be tested with cameras viewing the fire from ignition, instead of shuttering the fire exposure until it is developed. It is more realistic to have detection systems view the fire development.
