Specification text


Fire damper in line with the European product standard DIN EN 15650 in square or rectangle construction style with two large inspection accesses that can be operated without tools. Tested for fire resistance properties according to DIN EN 1366-2 (300 Pa and 500 Pa negative pressure), with CE label.

The fire damper manufacturer's declaration of performance (DoP) provides proof of the respective installation conditions, e.g. inside and remote from walls or ceiling slabs, along with the basic characteristics such as size, support structure, design, installation type and the respective classes of performance in accordance with the classification standard DIN EN 13501-3.

The ready-to-use units contain a release mechanism and an interchangeable, fire-resistant damper blade that can be arranged horizontally or vertically depending on the use.

Optimised low-leakage casing, up to tightness class C in accordance with DIN EN 1751 with 30 mm flange (L=500 mm) for connecting to ducting made of non-combustible or combustible building materials. Thermal release for 72 °C or 95 °C (warm air ventilation) with fusible link or thermoelectric with spring return actuator, test switch/push button and control LED.

The designs with brushless spring return actuators for opening and closing the fire damper – also when the ventilation system is running and independent of the nominal size – are particularly suited for function testing or the daily shut-off of cable sections.

Retrofit of spring return actuators without modification of the rod is possible from the outside.

 Suitable for:

            Mortar-based installation

  • In solid walls, lightweight partition walls, compartment walls, safety partition walls and radiation protection walls
  • In shaft walls with metal support structures or steel support structures
  • In timber stud walls and timber frame walls, as well as solid wood and cross laminated timber walls
  • In and on solid ceiling slabs and in combination with timber beam and solid wood ceilings

    Dry mortarless installation
     

  • In lightweight partition walls, compartment walls, safety partition walls and radiation protection walls with metal support structures or steel support structures
  • In timber stud walls and timber frame walls, as well as solid wood and cross laminated timber walls

  • In shaft walls with metal support structure or steel support structure

  • In dry mortarless installation remote from solid walls with installation kit
  • Remote from solid ceiling slabs (in horizontal ducts) with installation kit
  • Remote from lightweight partition walls (wall penetration)

    Fire batt installation
     
  • In solid walls, lightweight partition walls, fire protection walls, safety partition walls and radiation protection walls with metal support structure or steel support structure and timber stud, half-timbered construction, solid wood and cross laminated timber walls
