Real-scale fire tests in mock ship compartments were conducted to collect data of acoustic and spectral sensors and to experimentally evaluate the fire detection performance of three commercially available video image fire detection systems under various lighting and camera setting configurations. One goal was to establish an understanding of the performance sensitivity and limitations of the VID systems to various setup and environmental conditions that may occur onboard ship. The performance of the detections systems was compared to the response of multiple state-of-the-art smoke detection technologies for a range of fire and nuisance source exposures. Additionally, these tests provide a large database of information to evaluate the spectral and acoustic signatures of the various fire and nuisance sources. Toward this end, microphones, long wave-length video imaging and a test bed of single and multiple element sensors were included in the tests.
