Standards and guidelines

  • Construction Products Regulation
  • EN 15650 Ventilation for buildings – Fire dampers
  • EN 1366-2 Fire resistance tests for service installations – Fire dampers
  • EN 13501 Fire classification of construction products and building elements
  • EN 1751 Ventilation for buildings – Air terminal devices

Supply package

If attachments and accessories are factory set with the fire dampers, they are already included in the order code. Installation situations may require supplementary materials for assembly and fixing, such as mortar, screws, mineral wool, etc., to ensure correct installation. Such materials are not included in the scope of delivery, unless they are expressly described as part of the delivery. The selection of supplementary attachments or accessories as well as the determination and provision of materials for assembly and fixing is the responsibility of the parties involved in the construction and must be carried out taking into account the desired classification. 

Maintenance

  • 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. If 2 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


Technical data

  • Nominal sizes: 200 × 100 to 1500 × 800 mm
  • Casing lengths: 305 and 500 mm
  • Volume flow rate range: up to 14400 l/s / up to 51840 m³/h
  • Differential pressure: up to 2000 Pa
  • Temperature range: -20 – 50 °C
  • Upstream velocity*: ≤ 8 m/s with standard construction; ≤ 12 m/s with spring return actuator


* Data applies to uniform upstream and downstream conditions for the fire damper


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


The following applies to installation in Germany:

  • Do not use it in extract air systems in commercial kitchens
  • Do not use in combined penetration seal
  • Approvals under building regulations may be required for the use of air transfer units. This must be checked and applied for 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 M‑VV TB (2019/1) guideline. The applicable national building regulations must be adhered to

Accessories 2 – Flexible connectors


Application

  • Ducting must be installed in such a way that it does not impose any significant loads on the fire damper in the event of a fire. Be sure to comply with the relevant national guidelines and regulations
  • As ducts may expand and walls may become deformed in the event of a fire, we recommend using flexible connectors for installation in lightweight partition walls, shaft walls and lightweight compartment walls, as well as fire batt installation.
  • Flexible connectors should be installed in such a way that both ends can absorb both tension and compression
  • Flexible ducts can be used as an alternative
  • For heights > 400 mm, extension pieces are required due to construction
  • The fixing holes in the flexible connectors and extension pieces match those in the fire damper flanges
  • Flexible connectors are also available separately

Attachment – Duct smoke detectors

Application

  • To prevent smoke from spreading in buildings, it is extremely important that the smoke is detected at an early stage.
  • Duct smoke detectors that operate on the principle of light scattering detect the smoke regardless of its temperature so that the fire dampers can be closed before the release temperature of 72 °C is reached
  • If the air contains suspended particles, as is the case with smoke, beams of light are deflected off these. A sensor (photodiode), which does not receive light in clear air, is illuminated by the scattered light.
  • The fire damper or smoke protection damper blade is released when the brightness of the scattered light exceeds a certain threshold
