Isone+ – Fire dampers

  • CE marking-compliant in accordance with EN 15650.
  • Products tested to beyond European requirements under a minimum pressure of 500 Pa.
  • Fire class ratings obtained on main supports, assembly in all positions (blade horizontal and vertical) under 500 Pa and in both fire directions.
  • Flush-mounted range available in 2 versions:
    • FdP: very low pressure losses, used to minimise pressure loss created by the passing airflow.
    • EM: minimum dimensions to adapt to confined spaces.
    • Quick and economical to install using traditional mortar.
  • Ap wall-mounted range mounted in a few minutes, ideal for mounting on light partition wall (plasterboard).
  • Upgradeable Aldes mechanism:
    • Mechanism options can be specified at time of order or online at a later time (reset motor, signal contacts, etc.).
    • Extremely easy to upgrade: can be removed/inserted with one hand, no tools needed.
    • Full mechanism assembled by hand in less than 3 minutes.
    • Average verification time per damper reduced to 2 minutes.
    • Zero reset motor power consumption when in standby position.
  • Class B air tightness in accordance with EN 1751 to limit energy losses.
  • Consists of 2 metal sleeves on both sides of an assembly of refractory material.
  • Upgradeable mechanism box positioned on a sleeve.
  • Offset from the blade itself to avoid it being sealed into the partition during installation of the damper.
  • FdP flush-mounted range: available in circular (Ø 100 to 315 mm) and rectangular versions (200×200 to 800×600 mm).
  • EM flush-mounted range: available in circular (Ø 100 to 1000 mm) and rectangular versions (200×200 to 1500×600 or 1200×900 mm).
  • Ap wall-mounted range: available in circular (Ø 100 to 560 mm) and rectangular versions (200 x 200 to 800 x 600 mm).
  • ISONE upgradeable mechanism with options specified at time of order or online at a later time.
  • Trip options:
    • 70°C thermal fuse trip device: complusory for all dampers compliant with NF-S 61.937-5. A thermal, stainless steel rod is fitted into the mechanism box, held in place by a screw. Rapid access for fuse changes.
    • Electromagnetic trip device: operates on external command (e.g. Fire safety control system) via power emission (VDS) or power cut-off (VM) An exclusive development for the trigger enables operation under 24 V or 48 V DC. Manual switch between the two. Power: VDS ≤ 3.5 W / VM ≤ 1.5 W.
    • Manual control: compulsory for all dampers compliant with NF-S 61.937-5. White handle integrated into the unit for trip activation without removing the cover.
  • Reset options:
    • Manual reset: possible without removing cover.
    • EHOP 30S reset motor: resets the blade to standby position without manual action on the damper. Resets in less than 10 seconds. Max. current during reset: 0.7 A. Current absorbed at other times: 0 A. Voltage either 24 V and 48 V DC/AC.
  • Signalling options:
    • Contacts indicating blade position is closed (FCU1) or open (DCU1) or both.
    • Bi-pole contacts possible.
