Estimate a reasonable fire detection time is not only the condition of performance-based safety evacuation design, but also the basis of aerosol extractors start-up time determine for numerical simulation. In view of fire position environmental characteristics and fire detector characteristics, it is able to utilize fire dynamics models to estimate fire detection time. Fire detector methods today have been comparatively mature through long-term research and
practice. Several special application computer models, such as Argos, DETACT-QS, DETACT-T2
, LAVENT, JET, and so on, are available to assist in the design.
