Estimation of Fire Detection Time

Estimating the fire detection time is one of the important contents of performance-based fire protection design, which can be used to compute required safety egress time (RSET) and to determine the time of aerosol extractors start-up. In spite of that, the computing methods of fire detection time do not exist in current codes of China. Engineers often set a fixed fire detection time depend on their experience. In this thesis, a review is present demonstrating the detection time estimation methods of fire detectors, include fixed temperature heat detectors, rate of rise temperature heat detectors, light-scattering type smoke detectors, ionization-type smoke detectors, beam unit smoke detectors and radiant energy fire detectors.
