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...

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...

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...
