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

Attachment – spring return actuator

FKA2-EU with spring return actuator

Application

  • A spring return 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)

  • Motorised fire dampers can be used to shut off ducts

  • Two integral limit switches with volt-free contacts can indicate the damper blade position (OPEN and CLOSED)

  • The connecting cables of the 24 V spring return actuator are fitted with plugs. This ensures quick and easy connection to the TROX AS-i bus system. Without automation components, the 24 V connection is made via a safety transformer provided by others

  • A conversion kit is available for retrofitting an actuator to a fire damper with fusible link.

  • For the technical data and wiring examples, see the installation and operating manual for FKA2-EU.

Attachment – Spring return actuator and TROXNETCOM

FKA2-EU with spring return actuator and TROXNETCOM

Application

  • Fire dampers with a 24 V spring return actuator (Belimo) and the modules described here as attachments form a functional unit ready for automatic operation.

  • The components are factory assembled and wired

  • The combination 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

    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

  • 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

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
