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 fire damper; for a fire damper with spring return actuator this can be done by remote control....

Construction · Dimensions Characteristics Construction features – Classified according to EN 13501-3 – For classes of performance see the table on page 3 – 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 orientation for horizontal ducts from 0° up to 360° – Circular casing suitable for push fitting into cut circular holes without additional drilling and chiseling being required – Spigot connections on both ends, with lip seal, suitable for ventilation...

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. Construction variant 1 Casing Galvanised Powder-coated Stainless steel1 Galvanised Powder-coated Stainless steel1 Not for fire batt installation. Order code Damper blade Standard Standard Standard Coated Coated Coated – Casing in galvanised sheet steel, with powder coating RAL 7001 (1), or in stainless steel 1.4301 (2) – Damper blade made of special insulation...

Accessories 1 Installation block FKRS-EU fire dampers with installation block or dry mortarless installation kit are required for installation without perimeter mortar infill (dry mortarless installation). Installation block – Circular installation block ER for solid walls and ceiling slabs, the outer diameter of the installation block corresponds to standard core bits – Square installation block EQ for lightweight partition walls with metal support structure and cladding on one side or both sides, as well as for lightweight fire walls Fire damper and installation block are assembled at the factory...

Dry mortarless installation kit Dry mortarless installation kit – Square dry mortarless installation kit for lightweight partition walls with metal support structure and cladding on both sides, as well as for lightweight fire walls The fire damper and dry mortarless installation kit 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. A plate covers any joints and is used for screw fixing. Square dry mortarless installation kit – Dry mortarless...

Accessories 1 Wall face frame Wall face frame FKRS-EU fire dampers with wall face frame are required for dry mortarless installation on the face of solid walls. Fire damper and wall face frame 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. The wall face frame is fixed with suitable screws and anchors (with suitability certificate). Instead of anchors, threaded rods can be used (push through installation). Wall face frame – Wall face frame made of calcium silicate FKRS-EU with wall face frame...

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 may 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 – when used...

Attachments Limit switch FKRS-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 FKRS-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...
