FIELD: measuring equipment.
SUBSTANCE: method includes the presence of several channels connected to the reference channel, measurement channels located in the space at an equal distance from the common center, separating the amplitudes of the difference signals between the measuring channels, comparing the maximum of such amplitudes with the signal value in the reference channel, and upon exceeding the threshold according to the comparison results, forming the measuring results of the optical medium density to establish the presence of smoke.
EFFECT: significant increasing the fire detection rate in the early stages of its occurrence.
