요약
본 연구는 자동화재탐지설비의 신뢰도 증진 및 국민의 안전 확보를 위한 정밀한 점검기구의 개발에 기여하기 위해 현장에 설치되어 있는 연기감지기를 검정기술기준과 동일한 시험내용으로 현장에서 성능 시험을 실시할 수 있는 시험기를 개발하고자 하였다. 그 결과 연기발생원으로 종이를 사용하고 히터를 40초 이내에 $400^{circ}C$로 가열하여 시험이 가능하며, 광전식 연기감지센서를 통해 0~25%/m 연기농도의 측정 및 제어와 Fan의 rpm조절로 20~40cm/sec의 일정풍속 제어가 가능한 현장에서 좀 더 표준화되고 정밀한 성능시험이 가능한 휴대용 연기감도시험기를 개발하였다.
Abstract
In this study we could contribute to the development of a precise checking tool with which the reliability of the automatic fire detection systems was enhanced and the safety of the people was ensured. In the same way as the domestic technical standard, the portable smoke sensitivity tester, which was developed in this work, could be used to check the capability of the smoke detectors installed in the field. Its heater inside was warmed up to $400^{circ}C$ in 40 seconds and the paper as a smoke source was burned to produce smoke for the test. With the Photoelectric smoke detector it was possible to measure and control the smoke concentration in a range from 0%/m to 25%/m. With the adjustment of rpm of the fan, it was possible to keep a constant wind velocity in a range from 20cm/sec to 40cm/sec.
Key Words: Smoke detector, Sensitivity tester, Portable, Smoke source, Smoke concentration
