Ventilation air duct module for usage of the OTblue-LKM 802379 air duct smoke detector in combination with Venturi tubes 781446, 781447 or 781448. The module is mounted on the outside of the air ducts. The Venturi tube enters the duct and leads the air out of the duct through the detection chamber of the detector back to the duct and finally back into the duct. During operation, the detector and the alarm LED is visible so that an external parallel detector indicator is not required. The housing need not be opened for maintenance purposes. Inspection of the detector can be quickly easily performed via a separate opening in the front of the housing. Features & Benefits:

Single-tube air analysis system based on the Venturi principle

Optimum utilisation of air flow velocity through new Venturi tube design

Integrated maintenance opening in the front cover so that air duct smoke detector can be tested

Suitable for air duct widths from 0.6 to 2.8m

Integrated air flow displayCertifications:
