The electrical fire is one of the high rates among fire occurences. The electrical fire is reported as the highest rate with 23% of total fire occurence rate, and the industrial facility fire is known as the second highest rate with 17.3% of total fire rate. This study is focused on the development of more effective self triggered fire extinguishing system to protect the fire of high value facility and equipment such as electrical distributed system. The fire extinguishing raw material is the condensed aerosol which does not yield the corrosion and fault of fire equipments and facilities. The fire at the supply system of electricity such as electrical distributed system produce the large loss of not only the whole system but also the other fields relating to the distributed system. The electrical system therefore should be guaranteed for both safety and supply capacity together with the fire occurrence and earthquakes. It is accordingly to be triggered for fastest fire suppression and prepared for the minimum loss at the emergent situation. Based on these circumstances the fire extinguishing system of condensed aerosol has been known for the very effective measure particularly at the small size of enclosure. The self triggered system of condensed aerosol must however have the requirement of fast response capability. The heat type fire extinguishing system has not been enough to sense the total thermal value inside the enclosure. This paper is therefore to describe the advancement of self triggered smoke type extinguishing system of aerosol including more accurate and fast capability. The developed smoke type system provide the fast automatic suppression method with accurate test results for the electrical distributed system.
