FIELD: fire equipment.
SUBSTANCE: invention concerns devices of the fire alarm system, namely: to a design of fire-fighting smoke optic-electronic detectors. The device contains the case having demountable connection with the basis, where the electric contacts are fixed, and also the printed-circuit board with elements of the electronic scheme placed in the case and the optical camera containing a light source and a photo detector, thus the printed-circuit board is located between the case and the optical camera. The case can be supplied by the springs fixed in it by the central part and resting by one end in the printed-circuit board, and other end - in electric contacts of the basis.
EFFECT: decrease of production and maintenance cost, materials-output ratio, simplification of assemblage, service and repair.
