This study is based on the principle of solar power system and fire breakout. The result of the survey indicates that a solar power system is vulnerable to fire due to lack of maintenance after the installation. Currently the national fire safety agency does not have standards and legal provisions for the installation and maintenance of solar power facilities. Therefore, it increases the risk of fire breakouts as well as possibility of electric shock for the firefighters during fire fighting. This results possible damages to the human and equipments. In this study is proposing an automatic fire extinguishing system to reduce the power generation of solar panels during fire breakouts. Also, propose an over load current alarm system and fire prevention measures for fire fighters. The results of this study will be used as basic data for further fire testing of solar power systems.

Instruction and prevention of the safety for a fire have been performed continuously by nation. However, the accident due to a fire is not decreasing and causes a serious calamity to people. It is at the initial stage of fire burning that the most effective way to reduce damage is to evacuate and fight a fire. When a fire burns, the equipments reporting to other person or organization concerned are called 'acoustic reporting equipment'. Among those equipments reporting to person, 'a fire bell' is the easiest equipment to approach. Observing the behaviors of people when a fire burning, some are in a quiet indoor, some in a room with other people, some in a square with many people and some in indoor filled with smoke etc. This study aims to find out an acoustic reporting signal appropriate for visual information. For the experiments, visual-auditory experiments were performed through reporting signals and visual informations with several situations that is able to be faced at when a fire burns.

The prevention of disasters in cultural property is very important management and historical duties. The reason can't be measured values with monetary scale of our contemporary. Therefore, this paper was considered fire-safety as one of terrible threat-disasters about the wooden buildings. This research deal with 47 cases cultural property wooden building by whole investigation(field survey and interview) in Gangnung province. The most buildings have basic fire extinguisher; ABC powder. A few buildings are rarely installed fire extinguishing equipments; outdoor fire hydrant, heat sensor, ground sprinkler, CO2-hose-reel. But these state is very insufficient for the fire-safety in cultural property wooden buildings. Specially as particular attention in province, forest fire of regional characteristic have close relation with cultural property fire. The majority of factor against forest and building fire is to provide monitoring and security system; CCTV, Fence, Sensor, Alarm and paid guard man against incendiary. Ultimately it is necessary to construct comprehensive disaster prevention system with the organic cooperation such as National Emergency Management Agency, Cultural Heritage Administration, Forest Service, local government officials and regional citizen.

This study presents problems and improvement measures for the supply rate of single-alarm detector and fire extinguisher installed in households. Statistics from the NFDS show that 18 percent of all fires and 45 percent of deaths occurred in residential buildings over the past eight years. It was less than 60% that households be equipped rate of basic fire-fighting systems by 2019. In this study, I analyzed the law and statistics of fire to devise a method for fire safety. I proposed that the basic fire-fighting systems is be equipped in households. Like this : First, a free distribution policy for the over 60 years of age and Areas where is fire engine difficult to enter. Second, the policy of adopting safety pay in disaster. Third, the policy of expanding supply through the revision of the Licensed Real Estate Agents Act. Fourth, the policy of self-regulating installation by safety education and set up a data base system. Fifth make a law of household's National Fire Safety Standards.

This report is announced about test results of manually actuated signaling boxes(manual call points) and audible signal appliances (alarm bell), so as to occupants, inhabitants or persons di-rectly concerned with the implementation and direction of emergency action initialation is the area protected. The testing plan was progressed devided by three testing items, external appearance inspec-tion, performance test and environment proof test. The purpose of this report is to analyze the characteristics of products.

An arc/spark detector (ASD) was developed is to early detect wire failures and insecure connections that may lead to fire in residents and commercial and industrial facilities. A detailed circuit design for ASD implementation along with prototype product is reported. The tests of ASD, which were successful in phase identification, in many different arc/spark locations under different loadings, and in false alarm probability, showed the ability and capability of the state-of-the-art detector in the electric fire hazard prevention.

Rate of rise heat detectors that respond to the heat generated in fire plume and alarm when the temperature reaches a specified point, give a great influences to the loss of life and property according to their reaction sensitivity. In this study, simple equations were derived which can be predicted the response time and temperature of the rate of rise heat detector with the results of hot wind tunnel tests and compartment fire experiments.

건물내의 열을 온도 센서를 통해 모니터링함으로써 발생되는 온도 데이터의 양은 온도 센서의 정밀도가 향상되고 센서의 수가 증가함에 따라 기존의 화재감시시스템이나 공기조화냉동시스템에서 발생하는 것과는 비교할 수 없이 증가하게 된다. 이 과정에서 화재를 감시하기 위하여 유용한 데이터만을 처리해 데이터베이스화하고, 화재 예방에 활용하기 위해 온도 데이터의 효과적인 처리 방법을 연구함으로써 보다 작은 시스템의 구축으로도 안정적인 화재 감시 및 예방이 가능한 방안을 제시한다.

The radiant energy from a flaming fire of fuels containing carbonaceous material can be applied to fast growing fire. Raiant energy sensinsing technique applied detectors are ultimately effective when early detecting fire alarm system is required or the smoke and heat detectors can not be applied. This study investigated the characteristics of sun light, artificial light and flame radiation light and the foundation technique of flame detecting is established. Pyroelectric element proper for the characteristics of flame radiant energy developed and circuit stabilizing technique, electro-magnetic immunity technique, durable and reliable operating technique to circuits developed.
