FireMaster® Concertina™ Egress Fire Curtain

An electrically operated FireMaster® Concertina™ A1 Egress active fire curtain barrier assembly used to form a virtually continuous barrier as a fire separating element.

The system comprise a stainless-steel reinforced glass fibre fabric, fan-folded and retained in a metal tray, powered by an internal 24 V dc electric motor, enclosed within a 1.2 mm-thick stainless steel box. Within the main curtain assembly there is an egress door allowing for evacuation of personnel and for access for fire services. The egress door may contain up to two vision panels, allowing first responders visual access to the fire side of the curtain.

A bottom tray is attached to the bottom edge of the curtain providing tension to the curtain with sufficient weight for the curtain to ‘fail-safe by gravity’.

The 24V motor contains an electromagnetic brake to arrest motion of the curtain when in the open position.

The fire curtain assembly has been tested to the requirements of BS EN 16034:2014 for ‘Durability of Self-Closing against degradation’ (500 cycles on primary power and an additional 50 cycles using back-up power; closing speed of 0.08 m/s).

The assemblies have been tested to the requirements of BS EN 1363-1: for ‘Fire Resistance’ (90 minutes) and for ‘Radiation’ (60 minutes).

Operation:

FireMaster® Concertina™ A1 Egress active fire 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. During this period, the Barrier assembly will deploy on receipt of a signal. At the end of the period, the Barrier assembly will deploy.

Fire resistance:

90 minutes integrity.

Radiation resistance:

60 minutes <15 kW/m².

Product certification, performance and/ or testing:

• Barrier assemblies are certified by an independent accredited certification body operating to ISO/ IEC 17065:2012.
