Standards and guidelines

  • Construction Products Regulation

  • 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 for the ventilation system

  • For details on maintenance and inspection refer to the installation and operating manual

Functional description

In the event of a fire, tunnel fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. 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. 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). The spring return actuator is fitted with limit switches that can be used for capturing the damper blade position.

Quick sizing tables provide a good overview of the sound power levels and differential pressures that can be expected. Approximate intermediate values can be interpolated. Precise intermediate values and spectral data can be calculated with our Easy Product Finder design programme.

Square or rectangular tunnel fire damper to product standard EN 15650, tested to EN 1366-2, for the isolation of duct penetrations between fire compartments in the event of a fire. 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. The tunnel fire damper is suitable for installation in solid concrete or masonry walls. A 24 V/230 V spring return actuator closes the damper after it is triggered at 72 °C.

Application

  • An open/close actuator allows for the remote control of the fire damper and/or release by a suitable duct smoke detector
  • If the supply voltage fails, or with thermoelectric release, the damper closes (power off to close)
  • Fire dampers with spring return actuators can be functionally checked OPEN/CLOSED/ OPEN
  • Ambient temperature, normal operation –30 to 50 °C
  • Two integral limit switches with volt-free contacts enable the damper blade position indication (OPEN and CLOSED)
  • BF24-T-ST TR: The connecting cables of the spring return actuator are fitted with plugs, which ensure quick and easy connection to the TROX AS-i bus system; BF230-T TR, which is not fitted with plugs, can also be used

  • CORRECT USE
  • INSTALLATION DETAILS
  • BASIC INFORMATION AND NOMENCLATURE

Design information

  • The fire damper is used as an automatic shut- off device to prevent fire and smoke from spreading through ducting in tunnels

  • The fire damper is suitable for supply air and extract air systems

  • 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 are not permitted


If this fire damper is used in Germany

  • Do not use it as an air transfer damper
  • Do not use it in extract air systems in commercial kitchens

Installation types


Connection of the damper to the ductwork

  • The tunnel fire damper can be connected to one or two sheet steel ducts

  • Cover grilles can be connected to one side or both sides of the damper. These jobs have to be performed by others



Note

  • For further information relevant to design, in particular information on installation situations, please refer to the operating and installation manual.
