OPTONE® "+Grille" 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: Certificate 1812-CPR-1053,
• fire resistance classification as per EN 1366-10 test:
  • EI 90 (ved-i o) S - 1000 Pa - AA multi, in accordance 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,

• • EI 60 S for H > 1000.
• compliant with French standard NF-S-61937-10,
• leak rate < 200 m3/h per m² of leaf at 1,000 Pa,
• pressure losses damper only (with grille):
• • return: ∆p=2,083 .√(S_free/(LxH)).(Q/S_free)²,
  • supply: ∆p=2,00 .√(S_free/(LxH)).(Q/S_free)²,
  • ∆p in Pa, S_free m2, Q in m³.s-1, L and H in mm.
• free air passage (dm²): 2 flap = ((L-76) x (H-57) -14 147) / 10 000.

• motorised damper possible,
• electric control mechanism inside protective box,
• steel mounting frame 20/10 mm,
• grille frame attached to damper,
• nominal dimensions of damper L x H = installation space (opening) for mounting frame, attached without mortar seal,
• 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,
• available options:
  • galvanised steel trim, choice of RAL colour,
  • lockable core,
  • backdraft (required on air intakes if speed in ducts is above 7 m/s),
• mounting frame can be installed in factory.

• “multi-compartment” dampers are suitable for “single-compartment” applications,
• maximum negative pressure: - 1,000 Pa,
• direction of 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.
