Venturi air duct module for IQ8Quad OTblue-LKM

781463 | Venturi air duct module for IQ8Quad OTblue-LKM
Air duct module for usage of the OTblue-LKM multisensor detector IQ8Quad Part No. 802379/800379 or OTblue-LKM multisensor detector ES Detect Part No. 800379 in combination with Venturi tubes Part No. 781466, 781467 or 781468. The kit is mounted outside of the air duct system. The Venturi tube dips into the airflow of the system and conducts the air into the detection chamber and back and into the air duct system. During operation, the detector and the alarm LED is visible so that a remote indicator is not required. The housing doesn’t need to be opened for maintenance purposes. This can be easily done by using the separate opening in the front of the housing
Part-No.:
781463
Approval:
VdS
