Installation
BSKC9 is mounted on fire cell separating walls or floors,
alternatively in horizontal insulated ducts running through
fire cell separating building part, according to extensive
installation instructions. Should not be installed outdoors,
in damp or humid areas.
Actuator
BSKC9 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 MRB, MRB3,
FENIX monitoring systems. The damper can also be sup-
plied with 230V electric actuator.
Note that 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
When the damper is used to prevent the spread of fire
and smoke it must be closed via inputs from the smoke
detector. This must be fitted in the ventilation duct near the
damper or in another suitable location. Smoke detectors
are monitored by means of Bevent Rasch’s monitoring sys-
tem or the like. The system also performs automatic func-
tion tests on the damper every 48 hours and is designed
so that faults are indicated immediately and the damper
closes. See www.bevent-rasch.se for further details.

Use
Dampers in combination with walls or floors for fire-sec-
tioning of heating, ventilation and air conditioning instal-
lations 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, MRB3, FENIX), or
the like, the spread of fire/combustion gases is prevented.
No further action against the spread of fire/combustion
gases is required.
