Esser 781463 IQ8Quad OTblue-LKM Venturi Air Duct Module
Product Code: 781463
This unit, used to capture smoke in the ventilation duct, operates the IQ8Quad family's OTblue-LKM multi-sensor detector with Venturi tubes. The box is mounted outside the duct; the tube directs the sample taken from the air flow to the measurement chamber. It is used in air conditioning centers and air conditioning ducts. Since the detector and alarm LED are visible from outside, a parallel indicator lamp is not necessary.
