Fire dampers General information Functional description In the event of a fire, fire dampers shut automatically to prevent the propagation of fire Construction with fusible link and smoke through ductwork to adjacent designated fire compartments. In the event of a fire, the damper is triggered at 72 °C or at 95 °C (use in warm air ventilation systems) by a fusible link. The release mechanism is accessible and can be tested from the outside. Schematic illustration of FK-EU with fusible link ① Casing ② Damper blade ③ Travel stop for OPEN position ④ Travel stop for CLOSED position ⑤ Inspection access...

Fire dampers General information Function Construction with spring return actuator Functional description The spring return actuator enables the motorised opening and closing of the damper blade; it can be activated by the central BMS. In the event of a fire, the damper is triggered thermoelectrically at 72 °C or 95 °C (use in warm air ventilation systems). As long as power is supplied to the actuator, the damper blade remains open. If the supply voltage fails, the damper closes (power off to close). Motorised fire dampers can be used to shut off ducts. The torque of each actuator is sufficient...

Fire dampers Function 1 Construction with spring return actuator, explosion-proof Functional description The fire damper is used as a shut-off device to prevent fire and smoke from spreading through ducting in areas with potentially explosive atmospheres. The fire damper is suitable for supply air and extract air systems in potentially explosive atmospheres. For the operation of the fire damper, the operating and installation manual and the technical data in the additional operating manual must be observed. Use in areas with potentially explosive atmospheres (ATEX) According to declaration of...

Fire dampers General information Function Air transfer damper Functional description Air transfer dampers are designed to shut off openings for air transfer in fire resistant internal walls and ceiling slabs. To prevent smoke from spreading in buildings, it is extremely important that the smoke is detected at an early stage. Duct smoke detector Type RM-O-3-D is required to control and trigger the air transfer damper. The smoke detector operates on the principle of light scattering and detects the smoke regardless of its temperature so that the fire dampers can be closed before the release temperature...

Fire dampers FK-EU Design information – Approved only for use in ventilation and air conditioning sytems – A class of performance up to EI 120 (ve, ho, i ↔ o) S can only be achieved with ducts connected on both ends, or with a duct on one end and a cover grille on the other end. – If the fire damper is installed in a solid wall, solid ceiling slab, lightweight partition wall or shaft wall with a lower fire resistance class than that of the fire damper, the fire resistance class of the wall or ceiling slab applies also to the FK-EU (details upon request) – Ducting must be installed in such a manner...
