Venturi air duct housing for IQ8Quad OTblue-LKM (802379)
800379
Ventilation air duct housing for usage of the OTblue-LKM Part No. 802379 air duct smoke detector in combination with Venturi tubes Part No. 781446, 781447 or 781448. The housing 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 tube 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 is performed quickly and easily via a separate opening in the front of the housing.
