Characteristics of Optical Fire Detector False Alarm Sources and QualificationTest Procedures to Prove Immunity, Phase 2, Volume 3: Appendix 2

摘要

This study identified possible sources of UV, IR and visible radiations that maycause an optical fire detector to false alarm and/or affect its fire detection performance. The spectral irradiances of JP-4 pan fires and a multitude of lamps, hot bodies, and other of radiation stimuli that an optical detector may be exposed to in any type of aircraft shelter, hanger, facility, or ground location, were determined. Knowing the spectral irradiances of the required fire size and distance to be detected, it was then possible to determine at what distances would the potential false alarm source have to be to equal or exceed the fire's
