Mounting instructions, PYROLINE® BSK fire protection duct
About these instructions
1 About these instructions
1.1 Target group
These instructions are intended for specialists and/or instructed technical
personnel (e.g. engineers, architects, heads of construction, and mount-
ing and installation engineers) who have had fire protection training and
are charged with the installation of the fire protection duct.
1.2 Relevance of these instructions
– These instructions are based on the standards valid at the time of
compilation (October 2021).
– Follow these instructions to ensure correct and safe use.
– Any images are intended merely as examples. Mounting results may
look different.
– We will not accept any warranty claims for damage caused through
non-observance of these instructions.
– In these instructions, cables and lines are referred to simply as ca-
bles.
– These instructions describe standard solutions for mounting the PY-
ROLINE® Con BSK fire protection duct. Special solutions for specific
structural conditions are possible, but must be planned on-site with
the authorities.
– To find out more about planning and mounting the product, we recom-
mend a comprehensive training course.
1.3 Types of warning information
Type of risk!
Shows a risky situation. If the warning information is not observed, then
serious or fatal injuries may occur.
Type of risk!
Shows a risky situation. If the warning information is not observed, then
medium or minor injuries may occur.
Type of risk!
Shows a hazardous situation. If the safety instruction is not observed,
then damage to the product or the surroundings may occur.
Note! Indicates important information or assistance.
1.4 Intended use
The PYROLINE® Con BSK fire protection duct is used for the installa-
tion and guidance of cables up to a maximum diameter of d = 52 mm in
escape and rescue routes in interior areas of buildings. It protects emer-

About these instructions
gency and escape routes in building interiors against the effects of a cable
fire or, if there is a fire, secures the maintenance of electrical function of
safety-relevant electrical systems. The PYROLINE® Con PLC fire protec-
tion duct can be mounted on solid walls and ceilings, either directly or with
a support system.
Mounting must take place with fastening material with fire protection test-
ing. Ceilings and walls at the mounting location must be made of masonry,
concrete, reinforced concrete or porous concrete, and have a minimum
thickness of 12.5 cm (walls) or 12.5 cm (ceilings). Only then can the cor-
rect function of the fire protection duct be guaranteed.
The PYROLINE® Con BSK fire protection duct is not suitable for any pur-
pose other than that stated here.
The fire protection duct is not designed to support walls in wall penetra-
tions. Ensure that the wall penetrations can support themselves. Mount-
ing of the fire protection duct on dry or lightweight construction walls or
suspended ceilings shall not be considered proper.

Safety
2 Safety
2.1 General safety information
Observe the following basic safety information on handling the PYRO-
LINE® Con BSK fire protection duct:
– All the appropriate regulations and technical regulations of other units,
in particular those for electrical engineering, must be complied with.
– The fire protection duct may not be subjected to weights or used as a
support.
– The maximum permitted cable load should be selected according to
the total weight of the fire protection duct. The approved cable load
may not be exceeded, as otherwise the support and function capabili-
ty is no longer guaranteed.
2.2 Personal protective equipment
List of personal protective equipment to be used:
Wear safety shoes!
The weight of the fire protection duct can lead to contusions. Wear suita-
ble safety shoes during transport and mounting, in order to avoid contu-
sions or crushing injuries.
Wear head protection!
The weight of the fire protection duct can lead to head injuries when
working overhead. Wear a safety helmet when performing overhead
work.
Wear breathing protection!
If there is a fire, burning cable insulation can create corrosive gases. When dis-
posing of fire protection ducts which have been subjected to a fire, wear breath-
ing protection.
3 Necessary tools
List of required tools:
– Mounting lift, if the spatial conditions permit it
– Standard hand or coping saw with coarse saw blade, also suitable for
metal, to process the fire protection duct
– Manual machines with the option of connecting a vacuum cleaner for
automatic suction
– Drill
– Screwdriver
– Battery-operated screwdriver

protection duct
4.1 Product features
The PYROLINE® Con BSK is installed on interior walls and ceilings, to
route cables within. The fire-resistant material of the PYROLINE® Con
BSK fire protection duct fulfils the existing fire protection requirements
and, if there is a fire, prevents
– a fire from jumping to the cables and, as a consequence, electrical
systems failing, causing the creation of toxic smoke gases or
– toxic smoke gases spreading in rooms and escape routes.
The PYROLINE® Con BSK fire protection duct stands out through the
following properties:
– PYROLINE® Con D BSK version for direct wall or ceiling mounting
– PYROLINE® Con S BSK version, for wall and ceiling mounting with
support system of wall brackets or suspended supports and brackets
or threaded rods and profile rails
– Maintenance of electrical function for up to 90 minutes (maintenance
of electrical function class E30‒E90)
– Fire load encapsulation up to 120 minutes (I90–I120 classification)
– Material made of non-combustible fibre glass lightweight concrete,
water and frost-resistant, non-electrically conductive
– Hard, smooth and anti-friction compacted surface
– PYROLINE® Con D BSK version, primed at the factory, surface refine-
ment possible through plastering, wallpapering, painting
– Processing with standard tools such as hand saw or coping saw
– Fittings for corner connection, T connection, vertical jumps for the
PYROLINE® Con S BSK version
– Simple creation of standard and special fittings according to individual
requirements with the PYROLINE® Con D BSK version
– Mounting on OBO support systems
– Simple inspection and retrofitting
– I duct: Routing of standard cable types up to a maximum diameter of d
= 52 mm
– E duct: Routing of cable types with a rated voltage of max. 1 kV up to
a maximum diameter of d = 52 mm, no special cables with integrated
maintenance of electrical function required
