The FLAME ARMOUR Doorway Fire Shutter for Rigid Structures is a high performance, uninsulated fire shutter designed to maintain fire compartmentation across doorways, corridors and larger access openings. Tested to BS EN 1634-1 and classified to BS EN 13501-2, applicable configurations are available with integrity ratings of E60, E90, E120 and E240. An EW20 radiation classification is also available for openings up to 2.6m wide × 2.6m high, subject to the specified shutter configuration and direction of fire exposure. EW20 provides integrity and radiation performance but is not an insulation classification. The shutter is suitable for installation into masonry, concrete and appropriately fire protected structural steel. The supporting construction, fixings, finished floor detail and direction of fire exposure must comply with the applicable tested, classified or assessed configuration. Tubular motors provide a compact solution for smaller openings, while external chain driven industrial motors are available for larger openings. Permitted dimensions depend on the required rating, shutter construction, motor, barrel arrangement and supporting structure, so the appropriate specification will be confirmed at quotation stage. The control system is designed around the project’s fire strategy and may include a fire alarm interface, battery backup, local controls, manual override, audio-visual warnings and thermal activation. Where the shutter is installed across a circulation or escape route, its position and operating sequence must be approved by the project’s fire designer and Building Control. Installation must be completed by trained and competent personnel in accordance with the manufacturer’s instructions and project specific specification.
