| Summary: | 碩士 === 國立交通大學 === 工學院產業安全與防災學程 === 102 === Fire detector is a very reliable forewarning device; photoelectrical smoke detector is generally installed which concern the effectiveness for a given period of time. The effectiveness of period of time influence opportunity for locked people to escape. According to the Taiwan Fire Safety Equipment Approval Standard, smoke detector need to be installed in the vary type of locations, and one of this type- photoelectrical smoke detector is the priority option. However, the factors of the installed area are hard to control, such as, the wind speed, and the flow rate. For feature requested, most factories produced different type of features and appearance. Besides, in the current testing standard, the sensitivity tests of photoelectrical smoke detector was only on the actuating under standard concentration and limited time without the angle, direction, and vary flow rate consideration. However, if the factors consideration was ignored, false alarm caused easily which will decrease the available escape time. Therefore, flow rate and direction examination is a mainly subject for testing the sensitivity of photoelectrical smoke detector.
