    The air tightness class will be maintained if the damper is installed according to the installation manual. ∎ Rf-t fire dampers are always tested in standardised constructions according to EN 1366-2. The achieved results are valid for similar supporting constructions with a fire resistance, thickness and density equal or superior to the supporting construction used during the test.

    1. Remove the air-tight plug from the damper. 2. Insert the camera of the endoscope (for example Inspecam Rf-t) through the opening and inspect the inside of the damper. 3. After inspection, replace the air-tight plug thoroughly on the damper opening. The position is crucial in order to maintain the air-tightness of the fire damper.

    ONE Spring return actuator for remote control The spring-return actuator ONE is designed to easily operate Rf-t fire dampers of all sizes, automatically or remotely.Five models are available, 24 or 230 volt, with FDCU or FDCB position switches; and 24 volt with plug (ST).
  • Page 25 UNIQ Upgradeable operating mechanism for remote control Compliant with NF S 61-937, the UNIQ operating mechanism is designed to operate Rf-t fire dampers of all sizes, easily and remotely. Four models are available: with FDCU or FDCB position switches and with or without ME resetting motor. All models are dual-voltage 24/48V and with an electrical impulse triggering (VD) with a possibility to change to power interruption triggering (VM) by removing a jumper.
