Smokebarrier D120 Curtain

Smokebarrier rolling curtains are designed to restrict the lateral spread of smoke and hot gases along the underside of a roof, ceiling or balcony within a building, in the event of a fire. They are used as part of a smoke control system to create smoke reservoirs from which smoke and hot gases can be extracted, or to stop the spread of smoke, allowing valuable time for occupants to escape.

The smoke curtains have been successfully tested to meet the requirements of BS EN 12101-1 (D120), and are supplied with a gravity failsafe system, ensuring closure in the event of power failure. They are available in wide spans and can be face-fixed, soffit-fixed or suspended on rods.

Features and benefits:

• Curtain: constructed from coated grey fibreglass material, tested to withstand temperatures of up to 600˚C.
• Bottom rail: the lower edge of the curtain incorporates a triangular steel section to act as a weight bar.
• Endplates: fabricated from galvanized steel of adequate thickness, relative to curtain size onto which the tube is fixed.
• Casing: manufactured from galvanized steel, and is 158 x 150 mm for single curtains and 252 x 150 mm for multiple curtains.
• Side guides: the curtain is also available with side guides should there be a requirement that the curtain falls to floor level, or where an increased pressure differential is envisaged.
• Operation: electrical operation is by means of a 240 V tubular motor mounted inside the barrel. A control panel is provided at high level, and operates up to ten curtains. Closure in a fire condition is via gravity with a controlled descent. A single-phase socket is required within one metre of the control panel position.
• Fire activation: in a fire condition, activation is initiated by an incoming signal from the fire alarm system.
