Standards and guidelines

  • Construction Products Regulation
  • EN 15650:2010 Ventilation for buildings – Fire dampers
  • EN 1366-2:1999 Fire resistance tests for service installations – Fire dampers
  • EN 13501-3:2010 Fire classification of construction products and building elements
  • EN 1751:1999 Ventilation for buildings – Air terminal devices

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.
  • 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 of the ventilation system.
  • For details on maintenance and inspection refer to the installation and operating manual

Construction with fusible link

Functional description

In the event of a fire, fire dampers shut automatically to prevent the propagation of fire 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.

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 to open and close the damper blade even while the fan is running. The spring return actuator is fitted with limit switches that can be used for capturing the damper blade position.

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 supplementary operating manual must be observed.

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 is reached. The thermoelectric release mechanism of the spring return actuator also triggers the closure of the damper blade. When the release temperature (72 °C) is reached, the temperature sensor in the airflow interrupts the supply voltage to the spring return actuator. The spring return in the actuator causes the fire damper to close (power off to close). A second temperature sensor monitors the ambient temperature. If the supply voltage fails, the damper closes. Air transfer dampers consist of an FK-EU fire damper, an RM-O-3-D duct smoke detector with general building inspectorate licence Z-78.6-125, a spring return actuator (24 V AC/DC or 230 V AC) with two integral limit switches, and cover grilles on both ends.

Installation video

Fire batt installation of TROX rectangular fire dampers

In the past, openings for the installation of fire dampers in solid walls or ceiling slabs had to be of the exact size; only minimal tolerances were allowed, if at all. This has changed with fire batt solutions as they provide a new level of flexibility. With a fire batt, fire dampers can in fact be installed in openings that are much larger than the fire damper casing – the perimeter gap may be up to 400 mm wide. It is no longer a strict requirement that an installation opening fits the fire damper exactly.

Kranhaus Süd in the Rheinauhafen in Cologne

  • PROJECT
  • OUR JOB
  • SOLUTION
The “Rheinauhafen” (Rheinau Harbour) in the south of Cologne is a former industrial harbour and is currently redesigned into a bureau and living area. 
Within the Rheinauhafen a spectacular ensemble of three identical buildings, the so called Kranhäuser, was created by Linster architects, Trier/Aachen/Luxembourg and Bothe Richter Teherani, Hamburg and already achieved world fame. 
The tower in the middle, the Kranhaus1, was completed in 2008 and awarded the peoples choice award in the category business center in Cannes in March 2009. The twin building, the Kranhaus Süd, was inaugurated in 2009, the air conditioning technique was provided by the Pandomus Technische Gebäudeausrüstung GmbH and it was equipped with several TROX products.
In order to create a comfortable environmental atmosphere and highest possible safety in case of fire the Kranhaus Süd was equipped with slot diffusers, fire dampers, volume flow units and ceiling diffusers of TROX.
The slot diffusers and the volume flow units that are installed in the Kranhaus Süd provide a comfortable atmospheric Environment at low air velocities which helps the employees to work efficiently without being disturbed by draft in a secure working environment thanks to the use of fire dampers.
