A smoke detector is a device designed to detect the presence of smoke, which may indicate a potential fire hazard. Poltraf's offer includes optical smoke detectors for ventilation systems. The optical smoke detector reacts to visible smoke particles (combustion residues). It works on the principle of reflection. If smoke particles enter the measuring chamber, part of the light from the LED mounted in the measuring chamber will be reflected by the particles and hit the phototransistor, which activates the alarm. Smoke detectors are extremely important in preventing fires and protecting life and property. Detecting smoke quickly can give you time to evacuate or take firefighting action before the fire spreads.
