Fire damper BSK6 EI60
Installation
BSK6 is installed in duct work separating walls or joist sys-
tems, according to the adjoining installation instructions.
Should not be installed outdoors or in damp areas.
Actuator
BSK6 is always supplied with an electric safety actua-
tor with spring return complete with thermal sensor with
pushbutton for local manual operating test. The sensor
disconnects the power to the actuator if the temperature
exceeds 72°C inside or outside the damper. 24V actuators
are always used in connection with the MRB monitoring
system. Dampers can also be supplied with electric actu-
ator 230V.
Note that the BSK6 damper is always supplied with an
actuator.
Activation
According to Boverket’s Building Regulations smoke de-
tectors must be verified according to SS-EN 54-7 to acti-
vate dampers. The mandatory thermal sensor closes the
damper at 72°C according to ISO 10294-4.
Control and monitoring
When the damper is used to prevent the spread of fire and
combustion gases it must be closed via impulses from the
smoke detector. This must be fitted in the ventilation duct
in the proximity of the damper or in another suitable loca-
tion. Smoke detectors are monitored by means of Bevent
Rasch’s MRB system or the like. The MRB monitoring
system also performs automatic operating checks on the
damper every 48 hours and is designed so that faults are
indicated immediately and the damper closes.
See www.bevent-rasch.com for further details.

Use
Damper in combination with walls or joist systems for fire
separation of heating, ventilation and air conditioning in-
stallations in buildings. In accordance with the harmonised
European standard EN 15650:2010. In designs according
to associated documents, installation instructions and
when the damper is used in combination with smoke
detectors and monitoring system (MRB), or the like, the
spread of fire/combustion gases is prevented. No further
action against the spread of fire/combustion gases is re-
quired.

Options 1 and 2
1. Aperture equivalent to damper dimensions + 50 mm,
is produced in the building element.
When mounted in a drywall, horizontal metal joists
45x45 mm shall be applied as a frame in the wall
structure.
2. The damper is secured flat and tight using fire stopping
sealant (Intumex AN) against the wall/joist structure with
the fastening lugs, which are opened out.
When mounted in drywall, Spax screws shall be
screwed in to the joists.
3. Make sure the gap between damper and wall is 25 mm
all around. Sealing is carried out by caulking with miner-
al wool, min 40 kg/m3.
4. Fit the assembly plates RBMP on to the building ele-
ment, using appropriate fastening material.
When mounted in drywall, Spax screws shall be
screwed in to the joists. Attach the assembly plates on
to the damper, using stainless steel pop rivets through
the prepunched holes in the assembly plates.
Mount the pop rivets from the inside and out. Make
sure nothing is obstructing the movement of the
damper blade.
Building element (wall or joist structure) in fire resistance class EI60.
Damper’s fire resistance class: EI60 (ve ho i <-> o) S.
EC certificate 0402-CPR-SC1299-13
Option 1 Option 2
5. If fire damper is not connected to the duct system, fit
non-combustible grilles designed for the damper on the
unconnected sides. Connection piece RBFS may be
needed from sizes 600 mm or larger.
The minimum distance between the damper blade in
the open position and the grille is 50 mm.
6. Install the thermal sensor with the sensor body in the air
stream without obstructing the movement of the
damper blade.
7. Install the duct system according to applicable require-
ments.
8. Install the duct system according to applicable require-
ments. Make sure that the connected duct system
does not impact on the damper in the event of a fire
load.
• Minimum distance between dampers must be 200 mm.
• Minimum distance to joist structure/wall must be 75 mm.
• Horizontal installation of the damper spindle.
