Experimental Study on Measurement of Time to Reach Ignition Point Based on Installation of Addressable Detector in Traditional Market
Because fire in a traditional market spreads very fast, it is necessary to install an alarm system that can detect the fire early and identify the exact ignition point. The addressable detector can be used to identify the ignition point quickly using the address function. In this study, an existing general-type detector installed in a traditional market was replaced with an addressable detector, and firefighters measured the time taken to reach the initial ignition point. From the experimental results, the average time taken from DaeSin 119 Safety Center to reach the virtual ignition point on the 2<sup>nd</sup> floor of the 2<sup>nd</sup> district of Seomun Market was 3 min 12 s when the <general-type detector-P-type receiver> system was applied. However, the time was 2 min 8 s when the <addressable-type detector-R-type receiver>system was applied. Based on the experimental investigation, it was confirmed that the time required for firefighters to reach the initial ignition point decreased when the existing general-type detector was replaced with the addressable detector.
