Selecting the fire protection duct
5 Selecting the fire protection duct
Depending on the required classification, fire protection ducts with differ-
ent wall thicknesses and mounting systems are used.
5.1 Fire protection duct for direct wall/ceiling mounting
Direct wall and ceiling mounting is particularly appropriate when no
pipes need to be refitted, buildings refurbished or surface refinement is
required, in order to integrate the duct visually into the appearance of the
room. The duct covers are screwed to the duct trough.

function/fire resistance classes E30/I90 and E90/I120
5.2 Fire protection duct for mounting with a support system
Mounting with a support system is particularly useful if obstacles such as
heating, ventilation or water pipes or joists must be refitted. The support
system can consist of
– wall supports,
– suspended supports with support brackets and threaded rods,
– or threaded rods and support rails.
With wall supports, it is possible to compensate for greater differences in
uneven walls or avoid vertical cables or pipelines. Support systems with
a suspended support and support bracket are easier to fill with cables.
If suspended with threaded rods, a smaller mounting area under the
ceiling is required. The selection of the support system is aligned to the
local conditions.
The duct covers are not screwed to the duct trough, thus allowing rapid
inspection and refilling.

6 Planning an installation
To ensure the functionality of the fire protection duct, installations and
installation locations must fulfil technical and structural requirements.
6.1 Structural conditions
If there are uncertainties about the load capacity of walls and ceilings,
then a structural engineer must be consulted.
– Walls must be made of concrete, reinforced concrete or masonry (e.g.
calcareous sandstone, porous calcareous sandstone, full brick) with a
minimum thickness of 12.5 cm.
– Ceilings must be made of concrete, reinforced concrete or porous
concrete with a minimum thickness of 12.5 cm.
– Lightweight walls/partitions and wooden ceilings, as well as steel
structures and trapezoidal roofs, are not suitable for the mounting of
fire protection ducts.
– Walls and ceilings serving as a mounting surface must have at least
the same fire resistance length as the mounted fire protection duct.
– Mounting surfaces must be flat to avoid crack formation in the fire
protection ducts during mounting.
– The maximum approved tension in the suspended supports or thread-
ed rods is 9 N/mm² for the E30 maintenance of electrical function
class.
– If various electrical voltage levels are to be separated in a fire pro-
tection duct, the spacing of the various electrical voltage levels must
be at least 10 mm. Choose a fire protection duct with the appropriate
width/height and use separating clamps or brackets.
6.2 Approved fastening materials
Installed fastening materials must be fire protection-tested and certified
for the appropriate fastening substrate:

14 | EN OBO Bettermann
Planning an installation
– For direct wall/ceiling mounting, e.g. OBO bolt ties, type MMS-plus P
7.5x80, or similar with a rounded head, to avoid damage to the cables.
– For mounting on support systems, select the fastening material
according to the substrate and the requirements of the fire protection
duct to be fulfilled.

Planning an installation
6.3 Approved cables
PYROLINE® Con BSK fire protection duct for fire encapsulation (I90/
I120)
All cable types up to a rated voltage of 1 kV can be routed.
Note! Cables with integrated maintenance of electrical function may not be
routed in the same duct with cables for general power supply.
PYROLINE® Con fire protection duct for maintenance of electrical
function (E30/E90)
All cable types up to a rated voltage of 1 kV can be routed. There are no
special requirements for the fire behaviour of the cables.
Note! When dimensioning the cables, note that the electrical resistance of the
conductors in the cable is increased through heating. A larger conductor
cross-section may be required.
Comply with the maximum approved cable load (see Table 5). The
approved cable load is dependent on the classification and the mounting
version of the fire protection ducts:

Mounting PYROLINE® Con D BSK on a wall/ceiling
7 Mounting PYROLINE® Con D BSK on a wall/
ceiling
The PYROLINE® Con D BSK fire protection duct is mounted directly on
the wall in conjunction with separating brackets or under the ceiling with
separating clamps. The cables are later routed on the separating brack-
ets and separating clamps.
Danger of heavy components!
Fire protection ducts are very heavy and can cause serious injuries if they fall on
your head or other parts of the body.
Always work with a partner or work with mounting aids, such as scaffolding or
a mounting lift. Wear safety shoes. If mounting on the ceiling, wear protective
helmets.
Danger of cracking!
If the walls/ceilings are uneven, this can cause crack formations in the duct
trough if the means of fastening is too tight and the duct trough becomes
warped. Eliminate or compensate for uneven areas of the mounting substrate
before mounting.
Note! When shortening or notching out duct sections, take the width of a max.
3 mm joint with sealing strip into account.

of fastening, e.g. Ø 6 mm for the MMS-plus P 7.5x80 bolt tie. Drill the
holes alternately on the top and bottom marking line. Drill a hole half-
way along and the two other holes at a maximum of 100 mm to the
end of the duct section.

with countersunk
head screws on the duct trough. Mount the countersunk head screws
at a spacing of max. 300 mm and the spacing of the joints may be a
maximum of 50 mm.
3. Fully close joints to the wall

with KTM mortar.
4. Close off joints between two duct covers which are insufficiently com-
pressed or tight with KTM mortar.
The fire protection duct is fully mounted. If the fire protection duct is run
through the wall, or meets the wall, the wall connection must be designed
according to the mounting situation and classification, see chapter „7.10
