Content • Notes • Description Content • Notes • Description_ 2 Applications • Standard sizes • Weights_ 5 Functional Description • Circuit Diagram _14 Fire dampers are designed for automatic isolation of fire compartments in ventilation and air conditioning systems (RLT-systems). They are suitable for installation in walls and ceilings made of concrete resp. masonry, in gypsum wall boards, in lightweight partitions and L90-walls. The damper installation is independent of the air flow direction. The thermal release with the fusible link can be removed from the outside for easy inspection....

Connection of Ventilation Ducts According to the general building approval, fire dampers may only be connected to ventilation ducts that are unable to exert any significant force on the fire damper or on the wall or ceiling, on account of duct construction or layout, particularly when ducts heat up in event of fire. If this is not possible, flexible connectors must be located as shown in Fig. 4.1, Ref. No. 5 for installations shown in Figs. 1.2 to 1.7. A For installation as shown in Figs. 1.2 and 1.3 (if installation in walls made of gypsum wall boards), 2.1, 2.2, 3.1 and 3.2 ventilation...
