Performance

-

Smoke containment

Smoke performance BS EN 1634-3 <3 m³/h/m at 25Pa.

Fire resistance

120 minutes fire integrity and 87 minutes irradiance resistance BS 476-22, BS1634-1, 2 and BS EN 8524.

Activation

Volt free electrical signal will trigger the door to close under power or gravity control/ part close/ close under smoke detection signal/ close when signalled by fire alarm/ close on timer/ show a visual display ' Shutter Closing'/ sound an audio warning/ trigger a controlled descent unit activated by a battery backup power system.

Accessories

None.

Photocell.

(light beam sensor will detect the presence of a person or object that interrupts the light beam providing a non-contact safety system).

Arrangement

Vertical roller shutter for face fixing.

Barrel

Carbon steel tube finished with one coat rust inhibitive primer.

End plates

2–3m m (depending on curtain size/weight) carbon steel plates finished with one coat rust inhibitive primer.

Curtain

BS 1634-1 Fortress 240+ Fire Shield Fabric™ 640g/m² specially designed reinforced woven glass-fibre material coated on both sides with a reflective micronized aluminium polymer with an 120 min integrity and irradiance rating of 87 minutes. Galvanized steel bottom rail fabricated from 1.2 mm galvanized steel.

Guides

Fortress GCR-10 system™ 2/ 3 mm galvanized steel guides with a fabric retaining track system that prevents the curtain from dislodging from the guide under heat exhaust and ventilation pressure.

Headbox

1.2 mm galvanized steel 175 x 175 mm box assembly (variable), houses the curtain operator, barrel and curtain assembly. BS EN 12453 Galvanized steel roll-formed base bar with Fortress Anti-Catch System™ designed to avoid any lifting hazard.

Operation

BS EN 12453 Fortress FC IBM™ single-phase operator supply with normal day to day operation by low voltage key switch (24 Volt) linked to the building fire alarm system. On receiving a signal from the fire alarm, the control panel will either close the curtain under power close or controlled decent gravity drop. Control panel must be connected to a 13 A/non switched fused spur located within 1 m of the motor position.

Colour/ Finish:

Standard finish is galvanized steel guides, coil casing and bottom rail, with non-galvanized components finished with one coat rust inhibitive primer.


Door guides and canopy can be supplied BS EN 12206-1 DuPont® polyester powder coated (PPC) to the Fortress Pro-Tec range of 29 BS and RAL colours. Matt PPC finishes only. All finishes are applied in-house using an electrostatic process. Under normal circumstances average film thickness of 60-80 μm (microns) is applied. Non-standard colours are available on request - this may increase lead times. Please consult Fortress SEFA for advice.
