DUR-4046 - Optical smoke detector

The DUR-4046 processor optical smoke detector is designed to identify visible smoke that occurs at the initial stage of a fire, when the material is still smouldering, i.e. usually long before the appearance of an open flame and a noticeable increase in temperature. With automatic sensitivity compensation DUR-4046 maintans constant sensitivity in the event of progressive contamination of the measuring chamber and changes in pressure as well as condensation of water vapour.
