Abstract
An optical-based fire detection system has a fire detecting mode in which the system is monitoring a flammable region for occurrence of fire in the flammable region and a system calibrating mode in which functionality of the system can be verified. The system comprises a light signal collecting unit located inside of the flammable region. The system also comprises a light signal processing unit located outside of the flammable region. The system further comprises a light signal calibrating unit located outside of the flammable region. The system also comprises one or more optical fiber bundles optically interconnecting the collecting unit, the processing unit, and the calibrating unit. The optical interconnections, when the fire detection system is in the fire detecting mode, enable the processing unit to receive at least one light signal from the collecting unit and to process one or more characteristics of the at least one light signal to determine if the at least one light signal is indicative of a fire in the flammable region. The optical interconnections, when the fire detection is in the system calibrating mode, enable the processing unit to receive at least one calibrating light signal from the calibrating unit and to process the at least one calibrating light signal to verify functionality of the collecting unit and thereby to verify functionality of the optical-based fire detection system.
