Optical smoke detector FDOOT221

liquidelectronictwo-sensor

For the early detection of flaming fires caused by the combustion of liquid and solid matter, as well as smoldering fires. For the early and reliable fire detection in environments with deceptive phenomena. Works according to the scattered-light principle with two sensors, optical forward and backward scattering. Opto-electronic sampling chamber blocks disturbing extraneous light but optimally detects both dark and light smoke particles. Two additional heat sensors increase the fire detector’s immunity to deceptive phenomena. Signal processing with detection algorithms (DA). The base must be ordered separately. Also available in different colors.
