Abstract:

 The fire detection and alarm system is designed by aspirating smoke detector for ship cabin environment， for early detection of electrical smoldering fire. At the same time, the real fire test is carried out for the design results. The response time and the comparison results with the traditional detection and alarm system are obtained. Base on this，the response time performance of fire detection and alarm system is analyzed, the effectiveness and adaptability of the system are obtained. The numerical simulation of the protection part is carried out. Through the comparison and analysis of real fire test and simulation calculation，the applicability of the simulation method and theory is verified. Simulation calculation can be used to evaluate the rationality and effectiveness of the design, and predict the response time of fire detection and alarm of the most unfavorable point in the system under the given fire scenario.
