Pacchetto di fornitura

If attachments and accessories are factory-mounted on the fire dampers, they are already included in the order code. Depending on the installation situation, additional materials such as mortar, screws or mineral wool may be required for correct installation. Such materials are not usually included in the supply package (unless stated otherwise). Attachments and accessories have to be selected by people in charge of the building project. These people also have to select and provide any additionally required installation or fixing materials and make sure that the required classifications are met.


Manutenzione

  • The functional reliability of the fire damper must be tested at least every six months; this has to be arranged by the owner of the ventilation system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later.
  • A functional test involves closing the damper blade and opening it again; with a spring return actuator this can be done via remote control
  • Fire dampers must be included in the regular cleaning schedule for the ventilation system.
  • For details on functional tests, maintenance and inspection refer to the installation and operating manual


Dati tecnici

  • Nominal sizes: 100 to 315 mm
  • Casing length: 400 mm
  • Volume flow rate range: up to 770 l/s (2770 m³/h)
  • Differential pressure range: up to 1500 Pa
  • Temperature range: -20 - 50 °C *
  • Upstream velocity **: Standard version ≤ 8 m/s, version with spring return actuator ≤ 10 m/s, version with Ex actuator ExMax/RedMax-15-BF TR ≤ 10 m/s

* For FKRS-EU in Ex version, see supplementary operating instructions

** Data apply to uniform upstream and downstream conditions of the fire dampers


Utilizzo corretto

  • The fire damper is used as an automatic shut-off device to prevent fire and smoke from spreading through ducting.
  • The fire damper is suitable for supply and extract air in HVAC systems.
  • The fire damper may be used in areas with potentially explosive atmospheres if suitable special accessories are used with it and if the product bears the CE conformity marking according to Directive 2014/34/EU. Fire dampers for use in areas with potentially explosive atmospheres are marked for the zones for which they have been approved.
  • Operation of fire dampers is allowed only in compliance with installation regulations and the technical data in the installation and operating manual.
  • Modifying the fire damper or using replacement parts that have not been approved by TROX is not permitted.


Incorrect use:

  • without specially approved attachments in areas with potentially explosive atmospheres
  • as a smoke control damper
  • outdoors without sufficient protection against the effects of weather
  • in atmospheres where chemical reactions, whether planned or unplanned, may cause damage to the fire damper or lead to corrosion


For installation in Germany please note:

  • Do not use it in extract air systems in commercial kitchens
  • Do not use it as an air transfer damper
  • Do not use it with a combined penetration seal
  • Single installation in a sandwich panel wall is considered correct use. Do not combine it with cable penetrations
  • Air transfer units may require a building inspectorate licence. This has to be determined and applied for on a case to case basis (by others).
  • Flame-resistant building materials that form no dripping droplets (elastomer foams) have to be at least of fire rating class C - s2, d0 according to the German MVV TB (2019/1) guideline. The current national building regulations apply.
