This study was conducted to determine methods for improving sensitivity standards for smoke detectors. The smoke detection theory was theoretically reviewed, and local and international indoor air quality and sensitivity test standards were compared and analyzed. The results showed that the uniformity of the specimen, nonreflection of spatial characteristics, differences in experimental methods, and simple test conditions were limitations for local sensitivity test standards. Small-scale sensitivity tests performed according to Korean standards and Go/No-go tests (actual-scale sensitivity test) according to UL268 were conducted to improve the limitations of the Korean sensitivity test standards. The analysis results showed that carbon monoxide and particulate matter 10.0 could be used as factors when configuring test conditions. The equation between obscuration and selected factors was derived. The enactment of standards related to actual-scale sensitivity tests in Korea and the revision of test conditions by applying the equation of selected factors were proposed to improve sensitivity tests.

This study aimed to develop a framework for efficiently managing unwanted fire alarms in fire-fighting facilities. To this end, as a method of analyzing and considering the actual situation, the unwanted fire alarm management framework for firefighting facilities was developed by checking domestic and foreign factor classification and investigating related standards, the domestic unwanted fire alarms-related statistical status, surveys and fields. The main contents of the unwanted fire alarm management framework are composed of basic information and response, space, device, cause and outcome in five steps and each step is explained as an explanation of the preparation method, step-by-step composition, preparation form and preparation example. To utilize the developed unwanted fire alarm management framework, it was proposed to develop an unwanted fire alarm reduction manual for each stakeholder, use it as educational material for fire safety managers, develop a testing method based on an unwanted fire alarm scenario and develop an evaluation method for performance degradation due to aging.
