The Marc-Ok + fire protection curtain comprises the following components: the curtain sheet, the guide rails, the winding shaft, the shaft brackets, and a VIC drive unit. The curtain sheet is made of multi-ply textile. The primary component of the sheet’s multi-ply structure is steel-wire reinforced glass fibre. The top edge of the curtain sheet is attached to the winding shaft. Along the bottom edge of the curtain sheet is the ballast, which keeps the sheet properly taut (which removes creasing and provides proper winding on the shaft) and provides additional bracing. The winding shaft is installed on brackets attached to the partition. The winding shaft and the brackets are installed inside of the shaft box. The shaft box fascia is made from 0.7 - 1.0 mm galvanized steel sheet. The vertical edges of the curtain sheet carry running shoes which move inside of the guide rail profiles. The cross-sectional size of the guide rail.
The cross-sectional size of the guide rail is 80 x 120 mm. The guide rail fascia is made from 0.7 mm galvanized steel sheet. The guide rail and shaft box fascias are available in galvanized sheets coated in four basic colours, RAL 7035, 9002, 7016 and 9010. A custom colour or a stainless steel sheet version can be ordered. The product can be provided with a wide range of electrical accessories, like fire alarm systems, door position monitoring or access control solutions.
Curtain with multilayer structure. Outer layers in class A2-s1, d0, in accordance with EN 13501-1
The Marc-Ok + resilient fire protection curtains are intended for regulatory-compliant separation of fire zones inside and outside of buildings and across handling system flows.
Thanks to the low header installation height required, the curtain is perfect for installation at construction partitions, particularly in underground garage rooms and indoor shopping malls, where every square centimetre of usable floor area matters and the product dimensions must be minimised. For outdoor installations, the product can be installed on offset brackets to cancel cold bridges.
Marc-Ok + are resilient fire zone closures and given their high fire resistance rating, they can be a successful alternative to passive fire protection solutions which require a larger installation space. They can be installed in tandem with non-fire-rated doors or roller shutters.
For powered protection curtains, the curtain sheet is wound on the shaft and held open either by a brake or the self-arresting drive transmission. When a fire alarm is detected at the control inputs, the sheet is released and unwinds into the closed position.
The product is available in larger dimensions and with enhanced technical parameters on individual request.
