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 13501-3 Fire classification of construction products and building elements
  • EN 1751 Ventilation for buildings – Air terminal devices
  • 2006/42/EC – Machinery Directive


Supply package

If attachments and accessories are supplied from the factory with the fire dampers, they are already taken into account in the order code. Depending on the installation situations, supplementary materials for assembly and fixing may be needed to ensure proper installation, e.g. mortar, screws, mineral wool, etc. Such materials are not included in the supply package, unless they are expressly described as included in the supply package. The selection of additional attachments or accessories as well as the identification and provision of materials for assembly and fixing is the responsibility of those involved in the building project and must be done taking into account the required 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 2 consecutive tests, one 6 months after the other, are successful, the next test on the fire damper 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

  • 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
  • Use as air transfer damper only according to general type approval Z-6.50-2540
  • Do not use in combined penetration seal
  • Approvals under building regulations may be required for the use of upstream shutters of air transfer units. This must be checked and applied for by others

Technical information

Function, Technical Data, Quick sizing, Specification Text, Order Code

  • FUNCTION
  • TECHNICAL DATA
  • QUICK SIZING
  • SPECIFICATION TEXT
  • ORDER CODE

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.

One or two limit switches (optional attachment) can be used to indicate the damper blade position.

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 that a product is suitable for the respective installation conditions, e.g. in, on the face of and remote from walls or ceilings, with the stated essential characteristics such as size, supporting construction, construction and installation type, and that it has the corresponding class of performance to EN 13501-3.

The ready-for-operation unit includes a release mechanism and a replaceable, fire-resistant damper blade, which, depending on the application, can be either horizontal or vertical. Depending on application, classified from:

For Germany, the following applies when used as an upstream shutter of an air transfer unit:
If fire dampers with a purely mechanical shut-off element are to be used as an air transfer unit, the local building regulations must be observed. This may require building authority approvals. This must be checked and applied for by others. Usually the use of such upstream shutters of air transfer units is restricted to pressure differential systems.

  • AS interface is a global standard bus system according to EN 50295 and IEC 62026-2 
  • The module transmits the control signals between the spring return actuator and the controller and power unit
  • The control of the actuator and monitoring of run time for functional tests is thus possible 
  • The voltage (24 V DC) for the module and the actuator is supplied via the two-wire AS-i flat cable 
  • Function display: operation, 4 inputs, 2 outputs 

MODBUS RTU/BACnet MS/TP (RS485) 
  • MODBUS RTU and BACnet MS/TP are protocols for RS485 communication systems 
  • Data transmission is based on uniform protocols 
  • Only the bus line and the supply voltage remain to be connected by others 
  • MB-BAC-WA1/2: for the control of 1 – 2 fire dampers 
  • WA1/B3-AD: junction box for the 2nd fire damper with 24 V DC supply voltage to the MB-BAC-WA1/2 
  • WA1/B3-AD230: junction box with integrated power supply unit 230/24 V for connection of a 2nd motor-driven 24 V fire damper to the MB-BAC-WA1/2 LON 

LON 
  • LON indicates a standard local operating network system with manufacturer-independent communications 
  • Data transmission is based on a uniform protocol 
  • LonMark defines standards to ensure product compatibility 
  • Only the bus line and the supply voltage remain to be connected by others 
  • LON-WA1/B3: for the control of 1 – 2 fire dampers 
  • WA1/B3-AD: junction box for the 2nd fire damper with 24 V DC supply voltage to the LON-WA1/B3 
  • WA1/B3-AD230: Connection box with integral 230/24 V power supply unit for the connection of a second actuator-driven 24 V fire damper to LON‑A1/B3 

TNC‑EASYCONTROL
  • TNC-EASYCONTROL TNC-LINKBOX is a wiring aid for connecting a fire damper and the configurable parallel circuit for the TNCEASYCONTROL decentralised operating and monitoring system.

Attachment – Explosion-proof spring return actuator and TROXNETCOM

FK2-EU with explosion-proof spring return actuator and TROXNETCOM 
Application 

  • The fire dampers with spring return actuator ExMax/ RedMax-15-BF-TR and module AS-EM/C form a functional unit ready for automatic operation 
  • The combination explosion-protected spring return actuator with TROXNETCOM enables brand-neutral and cross-sector integration of various components (modules) in one network 
  • The modules control actuators and/or receive signals from sensors The module is to be installed and wired outside the potentially explosive atmosphere by others 

AS-i
  • AS interface is a global standard bus system according to EN 50295 and IEC 62026-2 
  • The module transmits the control signals between the spring return actuator and the controller and power unit 
  • The control of the actuator and monitoring of run time for functional tests is thus possible

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
