An electrically operated active fire curtain used to form a virtually continuous barrier as a fire separating element.

The 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) 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 edges of the curtain are retained inside side guides, providing pressure resistance of at least 20 Pa.

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


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 (2.362 in/s to 5.905 in/s) using the 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.

Curtain material:

The curtain material type is EFP™ 3/1000/CR/SS, which is a metallic based fire barrier. The material is halogen-free, resistant against attack from most chemicals, non-oxidizing acids, pitting and intergranular corrosion in continuous operation up to 400ºC. It has an area weight of 400 g/m² ± 10%.

The curtain material offers dimensional stability and is non-combustible to EN 13501-1 Reaction to Fire.
