OPTONE® "Classic" 2 flaps

In standby position, the damper is closed. It opens when instructed by the FACP and moves into failsafe position.

• CE marking compliant as per EN 12101-8: 1812-CPR-1055,
• fire resistance classification as per EN 1366-10 test:
  • EI 120 (ved-i o) S - 1 000 Pa - AA multi, in compliance with § 7.2.4 of EN 13501-4, certified on Promatect smoke exhaust duct L500, and on ducts compliant with EN 1366-9 of the same material and same density,
  • for H > 1000 mm: EI 60 (ved-i o) S - 1 000 Pa - AA multi, in compliance with § 7.2.4 of EN 13501-4, certified on Promatect smoke exhaust duct L500, and on ducts compliant with EN 1366-9 of the same material and same density.
• compliant with French standard NF-S-61937-10,
• leak rate < 200 m3/h per m² of leaf at 1,000 Pa,
• free air passage (dm²) with L and H in mm: 2 flap = ((L-76) x (H-57) -14 147) / 10 000,
• mounting frame and grille can be installed in factory.

• motorised damper possible,
• can be ordered in steps of 5 mm in L and H,
• electric control mechanism inside protective box,
• steel mounting frame 20/10 mm,
• choice of aesthetic aluminium frame,
• nominal dimensions of damper L x H = installation space (opening) for mounting frame,
• locking system mounted on flap for greater free surface,
• cable through holes included,
• locking system fitted with self-resetting electromagnetic trip device,
• scalable junction box,
• pressure loss for damper only (with grille):
• exhaust: ∆P=2.083 x √(S_free/(LxH)).(Q/S_free)2,
  • supply: ∆p=2,00 .√(S_free/(LxH)).(Q/S_free)2,
  • (∆p en Pa, S_free in m2, Q in m3.s-1, L and H in mm).
• available options:
  • galvanised steel trim, choice of RAL colour,
  • backdraft (required on air intakes if speed in ducts is above 7 m/s.

• “multi-compartment” dampers are suitable for “single-compartment” applications,
• maximum negative pressure: - 1,000 Pa,
• direction of fire: respect fire inside smoke exhaust duct (when damper is closed).
• use of mounting frame strongly recommended,
• use of CONCEPTOR DESENFUMAGE design software recommended to define the dimensions of the mounting frame installation space,
• if mounting frame already fixed to damper (no gaps), nominal LxH dimensions of damper = dimensions of opening,
• if mounting frame mortar sealed, add thickness of mortar to L and H,
• use detailed instructions for correct installation of flaps,
• damper can be inverted “upside down”,
• damper flush-mounted against vertical smoke exhaust duct,
• attached with 4 self-tapping screws supplied, on front face in mounting frame holes.
