* The 0.16 m long LKR-X TurboTube sampling tube is also suitable for larger channels and approved. There are no restrictions on the maximum
channel width / height / diameter. In conjunction with console KS-KRM-X®, channels to > = 80 mm diameter can be monitored. The longer LKR-Xs
can be shorted when required.
Note: For the control of fire and smoke protection flaps building authority approved smoke detectors with general FIRE PROTECTION
technical approval by the DIBt (German Institute for Building Technology) are required (see MVV TB for Germany).
