Smoke Curtain SmokeStop Concertina™ Closed - Rectangular - Concertina Smoke Curtain - Smoke Curtain Concertina

An electrically operated active smoke barrier assembly. Active smoke barrier assemblies comprises a metallic fabric, fan-folded and retained in a metal tray, powered by an internal 24 V d.c. electric motor, enclosed within a 1.2 mm-thick steel box. A special bottom tray is fitted to the bottom of the curtain providing tension to the curtain with sufficient weight for the curtain to ‘fail-safe by gravity’.

The edges of the curtain are retained inside side guides, providing pressure resistance of 20 Pa. The 24 V motor contains an electromagnetic brake to arrest motion of the curtain when in the open position. Active smoke curtain barrier assemblies have been tested to the requirements of EN 12101-1, Annex B for ‘Reliability and response times’ (1000 cycles on primary power and an additional 50 cycles using back-up power; closing speed of 0.07 m/s). Active smoke curtain barrier assemblies have been tested to the requirements of EN 12101-1 for ‘Temperature/ time resistance’ (120 minutes integrity). The fabric used in active smoke curtain barrier assemblies have a reaction to Fire Classification of ‘A1’.

Operation:

Active smoke curtain barrier assemblies commence movement upon initiation of alarm or power or system failure, and fully deploy to the fire operational position within the range of velocities of 0.06 m/s to 0.15 m/s using the unique VarioSpeed™ function. Operating speeds are site adjustable without altering the bottom bar mass. Speeds may be dictated by those authorities having jurisdiction for ‘safety in use’ according to the location, nature or function of each unit.

In the event of a mains supply power failure, the curtain is retained in the open position for a pre-determined period (nominally 30 minutes), using battery back-up power. At the end of the period, the barrier assembly will deploy.

Period of fire resistance:

60 minutes (1 hour) integrity.

Classification:

DH60, A1.
