RABR

Damper in combination with walls or joist structures for fire separation of HVAC systems in buildings. In accordance with the harmonised European standard EN 15650:2010. In designs in accordance with the associated documents and installation instructions and when the damper is used in combination with smoke detectors and monitoring system MRB or the like, the spread of smoke is prevented. No further action against the spread of smoke is required.

RABR is installed against horizontal or vertical building elements or horizontal ducts that pass through fire compartment separating building elements, in accordance with the adjoining installation instructions. Wall penetration RBVG is used for installation against building elements.

RABR is always supplied with an electric safety actuator with spring return complete with thermal sensor with pushbutton for local manual function test. The sensor disconnects the power to the actuator if the temperature exceeds 72°C inside or outside the damper. 24 V actuators are always used with the MRB monitoring system. Dampers can also be supplied with 230 V electric actuators. Note that RABR is always supplied with an actuator.
