FIELD: measuring equipment; fire safety.SUBSTANCE: invention relates to fire alarm devices, and is intended for detection of fire source in gas-dispersion systems (solid phase-gas) and determining its two-dimensional coordinates at heat radiation source. Proposed sensor comprises serially mounted inlet spherical lens, light flux splitter, two cylindrical lenses, each in its optical channel, light filters with different transmission spectra, single-coordinate radiation detectors, located perpendicular to each other and the optical axis of the sensor also includes two pairs of mirrors, each pair is located after each cylindrical lens.EFFECT: increased sensitivity, higher efficiency of fire-extinguishing or explosion suppression system.1 cl, 1 dwg, 1 tbl |
