CAUTION
Smoke extraction duct should be made in accordance with the duct manufacturer's guidelines. The ducts
must have adequate fire resistance in accordance with the fire resistance provided for the entire solution.
Seal all connections between the damper and the ducts with appropriate mortar / glue / gaskets, ensuring
fire resistance. The cut off damper in vertical position fire ventilation systems may be mounted across the
horizontal smoke extract duct or on the sides of the horizontal smoke extract duct or on the surface of any
side of the vertical smoke extract duct.
Inspection access
The mcr FID B damper is factory-equipped with an access inspection, thanks to which the connected duct
and the damper can be inspected without the need to disassemble the installation. The inspection can be
opened by unscrewing the 4 extreme screws as shown in the drawing above.

RB connecting subframe
The mcr FID B damper can be delivered by the manufacturer with a system assembly frame for
single-compartment fire ventilation ducts. Flanges allow the connection of ventilation ducts with the use of
clamps for fixing ducts. M10 rivet nuts located in the corners of the frame allow for centering the ducts. If
the RB assembly frame is assembled on its own, the connection should be sealed with fire rated material
that provides the appropriate fire resistance for the application.
