OVERVIEW, DESIGN AND PROPERTIES

The Marc-K fire protection curtain comprises the following basic components: the curtain sheet, the winding shaft, the shaft brackets, a system of guide rails, the ballast strip, the sight box, and the drive unit.

The curtain sheet length is specified so that the bottom edge of the curtain is in contact with the sill surface with the curtain completely unwound. Along the closing edge of the curtain is the bottom ballast strip installed.

The guide rail and shaft box fascias are available in galvanised sheet coated in three basic colours, RAL 7035, 9002, and 9010. A custom colour or a stainless steel sheet version can be ordered

Zastosowanie produktu Marc-K

INTENDED USE

The Marc-K resilient fire protection curtains are intended for regulatory-compliant separation of fire zones inside and outside of buildings.

Thanks to the low header installation height required, the curtain is perfect for installation at construction partitions 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.

Operating principle

The Marc-K curtains up to 2.5 m wide and 3.0 m high can be provided with a gravity-assisted drive unit. The product is triggered to close with a thermal fusible trip. The torsion spring installed in the shaft ensures a constant closing speed and provides an easy opening action without any additional drive operators, like cranks.

For powered curtains, the curtain 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.

In the spring-loaded curtain version (which features no electric drive unit), the curtain door sheet is wound on the shaft and held so by a thermal fusible trip, which breaks at approximately 74°C to unwind the curtain and close the opening.

OPTIONAL ACCESSORIES

  • Can be provided with a wide range of electrical accessories, including fire alarm systems, curtain position monitoring, and access control solutions;
  • Fire alarm control panel with an UPS pre-wired for interfacing with the field fire alarm system and/or local smoke/heat detectors
  • The electrical accessories can be kitted with the fire alarm control panel and include: remote control panel, smoke and/or heat detectors, fire alarm indicators (sounders and/or beacons), and an open and/or closed position sensor
  • Drive units available with gravity assisted closing action or hand-operated opening action.
