Polon Alfa DUO – 6046 Smoke detector, Addressable multi-sensor smoke, and heat detector DUO-6046 are designed for the detection of visible smoke or/and the rise of temperature at the very early stage of fire. The detector is resistant to air movement and air pressure changes. Using the doubled smoke sensor (IR and UV range) and doubled heat sensors guarantee high resistance to false alarms caused by water vapors or dust while maintaining small dimensions and high aesthetics of the detector. DUO-6046 detector is dedicated to operation on addressable detection loops of POLON 4000 and POLON 6000 systems fire alarm control panels.
