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.

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.
