An electrically operated active smoke curtain barrier assembly used to form a virtually continuous barrier against smoke. Barrier assemblies comprise a metallic fabric wound on to a steel roller, powered by an internal 24 V d.c. electric motor, enclosed within a 1.2 mm (0.047 in) thick stainless steel box. A bottom bar is fitted to the bottom edge of the curtain providing tension to the curtain with sufficient weight for the curtain to ‘fail-safe by gravity’.

The 24 V motor contains an electromagnetic brake to arrest motion of the curtain when in the open position. Barrier assemblies have been tested to the requirements of BS EN 12101:2006, Annex B for ‘Reliability and response times’ (1000 cycles on primary power and an additional 50 cycles using back-up power; closing speed of 0.15 m/s). Barrier assemblies have been tested to the requirements of BS EN 12101:2006, Annex C for ‘Permeability of materials to smoke’ (0.3 m3/h/m2. Barrier assemblies have been tested to the requirements of BS EN 12101-1:2006, Annex D for ‘Temperature/ Time Resistance Tests’ (150 minutes integrity).

Period of Fire Resistance:

150 minutes integrity. (DA150)

Certification:

Complete barrier assemblies are certified by an independent accredited certification body operating to ISO/IEC 17065:2012. Complete barrier assemblies are certified with an independent accredited certification body operating an accredited United Kingdom Accreditation Service (UKAS) scheme for installation, commissioning and servicing.

Operation:

Barrier assemblies commence movement upon initiation of BMS 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. During this period, the SmokeStop® D600A active smoke curtain barrier assembly will deploy on receipt of a signal. At the end of the period, the Barrier assembly will deploy.
