FireMaster Concertina

CONCERTINA FIRE CURTAIN CONSTRUCTION

Concertina is a folding fabric fire curtain where the complete construction is concealed in the headbox in the ceiling. The headbox traverses the perimeter of the void in a uniform design. The fabric is constructed in strips forming a pleated design. These are stitched together horizontally. The material keeps the memory of the folds as manufactured. Each corner is specifically cut, folded and constructed to create any angle from 60° to 180°. As the bottom tray deploys, these pleats unfold. During retraction of the curtain the pleats will neatly fold back to their stored position

BOTTOM TRAY

Standard bottom tray is 300mm wide and provides complete access into the head-box when deployed. A slim line version is available with a 170mm wide bottom tray. Metalwork is zinc coated mild steel. This can be painted on site or powder-coated to RAL colors.

HOW TO OPERATE THE FIREMASTER CONCERTINA FIRE CURTAIN

The FireMaster Concertina Fire Curtain will remain retracted within its head box until it is automatically activated by the fire alarm signal. Once activated it will completely close the opening, creating a fire and smoke compartment. Deployment is by gravity at a controlled speed of 0.06 – 0.1m/s. The only true gravity failsafe product on the market. Testing is performed by a simple key switch. It is reset manually by pressing a reset button on the control panel. Automatic reset is available.
