FIELD: fire safety. ^ SUBSTANCE: invention relates to fire prevention. Automatic fire-fighting system includes alarm means, modules of two-thresholds operation behaviour, each of which contains a block of readiness, and block controlling activation of fire-fighting generators, distributed in protected space. At the same time the control block commutated with a temperature-sensitive element of prethreshold and threshold fire thermal factor. The temperature sensitive element of the prethreshold value of the fire thermal factor joined through the block of readiness. Each module is additionally equipped with a flame sensor which is switched parallel with temperature sensitive element of the threshold value of fire thermal factor to the control block through a programmed channel switch of fire-fighting doubling by independently joined with its outlets of emergency fire-fighting generators parallel switched to the channel switch through devices of regulated time delay and having the form of aerosol and/or powder. ^ EFFECT: invention allows increasing system reliability. ^ 3 dwg |
