A Study about False Alarm via a Code-transmitter of The Automatic Fire Detection System
초록
영어
The research on improvement of false alarm from the automatic fire detection system has been continually achieved in the meantime. But the research for the code-transmitter as one of component devices of the automatic fire detection system. In order to improve difficulty of the code-transmitter check-up, introduction for the address type-code-transmitter and the automatic recovery system for check up of the code-transmitter was proposed. In order to prevent against occurrence of noise and signal attenuation, introduction of the optical fiber cables that noise and signal attenuation do not occur and introduction for an optical communication relay that can apply to was proposed respectively.
