Abstract
Comparative investigations of the conventional analog and optical communication analog fire detector signal attenuations with various numbers of fire detectors were performed in this research. The conventional fire detector signals with 1, 2, 16 and 32 fire detectors were 4.5, 4.0, 2.2 and 0.8 V, respectively. The fire detector signals were drastically decreased with the increase of the number of fire detectors. However, the optical communication fire detector signals were not changed with increasing the number of fire detectors. Therefore, optical communication fire detector system is a promising fire detection system for eliminating the false alarms.
