Abstract
In general, small buildings and residence housings rely on manual fire extinguishers instead of automatic fire suppression systems, which causes bigger disasters during the absence of human-beings or in the presence of children or the olders. For this reason, simple structured and low-cost automatic fire extinguisher using fusible metal detector was newly developed and patented. In this paper, some field tests were carried out to investigate its fire suppression performance. As a result, reaction time of the detection parts varied from 2 min 19s to 7 min 20s depending upon the room size and installation position. It was suggested that to reduce reaction time within 3 minutes, fusible metals with lower melting point should be adopted and the installation location should be moved to near ceiling instead of below 1.5 m.
