ABSTRACT:
Fire observation system comprises a central receiving device and detectors, said central receiving device being provided with a remotely searching means for generating detection mode changing signals to continuously change the quantity of detection from a small value to a large one by means of electrical output units, which are connected to the detectors and can feed an output corresponding to the quantity of detection detected by each of detectors, and each of detectors being provided with an intrinsic signal feeding means for causing each of detectors to receive the detection mode changing signal and feed to the central receiving device the quantity of detection detected by the detector at the place where a fire is developing. Said fire observation system is intended to observe the condition of area surrounding a place where a fire is broken and search the development of fire at the place, after the break of fire is warned by detecting a predetermined reference value of a matter such as smoke, temperature and light.
