Fire damper BSK9 EI90
Installation
BSK9 is installed in fire cell separating walls or floors,
according to the adjoining installation instructions. Should
not be installed outdoors, in damp or high humidity areas.
Actuator
BSK9 is always supplied with an electric safety actuator
with spring return complete with thermal sensor equipped
with push button for local manual operating test. The sen-
sor breaks the power supply to the actuator device if the
temperature exceeds 72°C inside or outside the damper.
24V actuators are always used with the FENIX monitoring
system, MRB3 and MRB. The damper can also be supplied
with 230V electric actuator. The damper is always supplied
with a safety actuator.
Activation
The Boverket Building Regulations state a requirement
for smoke detectors verified in accordance with
SS-EN 54-7 for activation of dampers. The obligatory
thermal sensor closes the damper at 72°C in accordance
with ISO 10294-4.
Control and monitoring
Dampers for protection against the spread of fire and com-
bustion gases shall be closed via inputs from a smoke de-
tector. Smoke detectors are mounted in ventilation ducts
or monitored spaces. Fire dampers, smoke detectors and
ventilation units are connected to the FENIX, MRB3 or
MRB control unit for a complete ventilation fire protection.
FENIX, MRB3 and MRB perform functional checks of the
fire protection in accordance with current regulations.
3d party panels also possible. Please check compability first.
See www.bevent-rasch.se for further details.

Sound data
The speed is calculated on the damper’s gross area, i.e.
one BSK9 - 400 x 400 has a gross area of 0.16m2.
The specified pressure drop applies to the damper without accessories.

Options 1 and 2
1. Create a hole, corresponding to the damper’s nominal
dimensions + 50 mm, in the building element.
If installing in plasterboard, a steel reinforcement frame
of 45x45 must be used.
2. The damper is secured flat and tight using fire-retardant
sealant between the damper and wall/joist structure
with all fastening lugs, which are opened out.
Screw Ø 5mm with a minimum length of 45mm to be
used when mounting in drywall. The screw is pulled
through the reinforcement stud.
3. Check that the gap between the damper and the wall
is 25 mm all the way round. Sealing is carried out by
caulking with mineral wool, min 40 kg/m3.
4. Fit the cover frame against the substrate with suitable
fixings. Now fasten the frame on the damper with steel
blind rivets Ø 5mm through the pre-punched holes in
the mounting frame. Fit with blind rivets from inside out.
Ensure that the damper blade runs freely.
Building element (wall or joist structure) in fire resistance class EI90.
Damper’s fire resistance class: EI90 (ve ho i <–> o) S.
EU certificate 0402-CPR-SC1299-13
Option 1 Option 2
5. When using a Fire damper as a transfer-air or end
device, a non-combustible louvre intended for the
damper must be mounted on the non-connected sides
of the damper.
The minimum distance between the damper blade in
the open position and the louvre is 50mm.
6. Connect the actuator device to the control unit and
carry out a function check.
7. Install the duct system according to applicable require-
ments. Ensure that connecting ducts systems do not
affect dampers during fire loading.
• The shortest distance between dampers must be
200 mm.
• The shortest distance to wall/floor must be 75 mm.
• The damper shaft must be mounted horizontally.
