Function loss!
If improperly filled, the strain relief function can be impaired. Maintenance

es with low or no assignment are filled with foam blocks. Residual joints
between the foam blocks must be filled with FSB-SP fire protection filler.
The remaining spaces are filled with fire protection foam. The housing
can also be filled completely with fire protection foam.
In the following, it is shown how the housing on the suspended vertical
ladder is filled. The housing directly fastened to the wall is filled in the
same way with foam blocks and/or fire protection foam.
Note!
To prevent the foam blocks from falling out or to prevent the fire protection
foam from expanding too far, the housing can first be sealed from below,
e.g. with adhesive tape. After mounting, adhesive tape or similar aids
must be removed again.
