BSK120

Damper in combination with walls or joist systems for fire separation of heating, ventilation and air conditioning installations 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 required.

BSK120 is installed in fire cell separating walls or joist systems, according to the adjoining installation instructions. Should not be installed outdoors or in damp areas.

BSK120 is always supplied with an electric safety actuator 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 actuator 230V. Note that the BSK120 damper is always supplied with an actuator.
