Correct use To ensure complete functioning of the fire damper it is essential to read the operating and installation manual and to comply with it. In addition, the national guidelines must be complied with. The general guidelines of DIN 31051 and EN 13306 are also applicable. The functional reliability of fire dampers must be tested at least every six months. If two consecutive tests are successful, the next test can be conducted one year later. In general, it is sufficient to release and re-open the damper blade; for fire dampers with spring return actuator this can be done by remote control....

Construction · Dimensions Characteristics – Classified according to EN 13501-3 – For classes of performance see the table on page 3 – Combustible ventilation ducting may be connected directly – Airflow in either direction – Large free cross sectional area, hence low differential pressure – Release temperature 72 °C or 95 °C (for use in warm air ventilation systems) Approved installation positions for horizontal ducts Release mechanism Construction features – Rectangular construction, rigid frame – Connecting flanges on both ends, suitable for duct connection with System 30 flanges – Closed blade...

Construction · Dimensions The construction variants with stainless steel or powder-coated casing meet even more critical requirements for corrosion protection. They are also available with a coated damper blade. Detailed listing on request. – Casing in galvanised sheet steel, with powder coating RAL 7001 (1), or in stainless steel 1.4301 (2) – Damper blade made of special insulation material – Damper blade coated in RAL7001 – Damper blade shaft in stainless steel – Plastic plain bearings Construction variant 1 Casing Galvanised Powder-coated Stainless steel Galvanised Powder-coated Stainless...

Installation block · Cover plate Installation block FKS-EU fire dampers with installation block are required for installation without perimeter mortar infill (dry mortarless installation). Fire damper and installation block are assembled at the factory and form a unit. The unit is installed without a mortar-mix by simply inserting it into the prepared installation opening. In case of a fire the foaming seal closes the remaining gap. Installation block Cover plate Cover plate A cover plate simplifies the installation with perimeter mortar infill (wet installation). It can be screw fixed to a solid...

Cover grille · Flexible connectors Flexible connectors Ducting must be installed in such a manner that it does not impose any loads on the fire damper in case of a fire. For information on how to limit such loads please refer to the guideline regarding fire protection requirements on ventilation systems (Lüftungsanlagen-Richtlinie, LüAR). As ducts may expand and walls become deformed in case of a fire, we recommend for the following applications using flexible connectors when connecting the fire damper to rigid ducts: – in lightweight partition walls – in lightweight shaft walls The flexible...

Attachments Limit switches FKS-EU with fusible link Order code Standard construction Limit switches with volt-free contacts enable the damper blade position indication. Relays or indicator lights for fire alarm systems can be used up to the maximum switch rating. One limit switch each is required for damper blade positions OPEN and CLOSED. Fire dampers with a fusible link can be supplied with one or two limit switches; the switches can also be fitted later. Standard construction with limit switch for damper blade position CLOSED Standard construction with limit switch for damper blade position...

Attachments Spring return actuator FKS-EU with spring return actuator Order code Operation of the fire damper with a spring return actuator allows remote control and/or release by a suitable smoke detector. If the supply voltage fails, or with thermoelectric release, the damper closes (power off to close). Fire dampers with spring return actuator can be functionally checked OPEN/CLOSED/ OPEN. The actuator includes two limit switches. The connecting cables of the BLF24-T-ST TR are fitted with plugs. This ensures quick and easy connection to the TROX AS-i bus system. A conversion kit is available...

Attachments TROXNETCOM FKS-EU with spring return actuator and TROXNETCOM Order code The fire dampers with spring return actuator BLF24-T-ST TR and the modules shown here as attachments form a functional unit ready for operation by an automatic fire damper controller. The components are factory-assembled and wired. Only the bus line and the supply voltage (LON only) remain to be connected by others. The AS interface is a world-standard bus system according to EN 50295 and IEC 62026-2. It enables the integration of different components (modules) in a network regardless of the manufacturer and the...
