CE.jpg nf.jpg

  • Scalable valve on site
  • Tightness class B according to standard EN 1751
  • UNIQ FDCB universal mechanism

Application

Intended for the compartmentalisation of public buildings (public buildings) and high-rise buildings (high-rise buildings).
Autocontrolled or remotely controlled Actuated Safety Devices (DAS), intended to restore the fire resistance characteristics of walls or floors crossed by a duct in the event of a fire and to isolate the disaster area.
Use inside buildings.
Can be mounted in any position (blade axis installed 0 to 360 °).
Range of valves validated for installation at a distance less than the minimum imposed by the European test standard, on vertical and horizontal walls.
For circular valves, the minimum distance is set at 30 mm.

  • 9 sizes: Ø200/Ø250/Ø315/Ø355/Ø400/Ø450/Ø500/Ø560/Ø630 mm.
  • 2 control mechanisms:
    • CFTH: self-controlled single-trip mechanism by 72°C fuse.
    • UNIQ VD/VM FDCB 24 or 48V release or break tripping with end contact and bipolar start of travel, as standard.
    • UNIQ VD/VM FDCB ME: triggering by emission or break 24 or 48V with end contact and start of bipolar run and reset motor.
  • Flush mounting.

Description
  • 72° C thermal fuse supplied.
  • Manual trigger possible.
  • Manual reset possible (handle provided for CFTH mechanism).
  • Sealing class B according to standard EN 1751 as standard across the entire range (C optional from Ø315mm).
  • Control mechanism entirely out of the wall.
  • Galvanized steel tunnel, extended tunnel version lg. 500mm: contact us.
  • Intumescent seal.
Simple self-controlled mechanism CFTH:
  • The damper closes automatically as soon as the temperature in the duct exceeds 72°C.
  • The reset of the valve is done manually.
UNIQ remote control mechanism:
  • The damper closes automatically as soon as the temperature in the duct exceeds 72°C.
  • The damper can also close by current emission (VD) or current failure (VM) in voltage 24 or 48V.
  • As standard, the mechanism will be delivered in current emission (VD), the passage to power failure on site will be done by switching a switch.
  • The resetting of the valve is done using a 9V battery (not supplied) to be inserted in the compartment provided for this purpose.
  • The ME reset motor can be delivered factory-assembled or supplied as a kit for on-site assembly.
  • The UNIQ VD/VM FDCB kit allows the simple CFTH mechanism to be replaced on site by the UNIQ remote-controlled mechanism.
