Dual-technology detectors (smoke-heat) work according to the light scattering principle caused
by smoke particles present in the air (TYNDALL effect) and on temperature monitoring within
the area where they are installed. A micro controller analyses and compares the signal received
from a precision heat detector of the NTC type, and activates the alarm if temperature goes
over 58°C. The smoke detector features an automatic gain control function; a microcontroller
calculates reading compensation to keep constant sensitivity.
