Electrically operated active fire curtain barrier assembly, used to form a virtually continuous barrier as a fire separating element. The barrier assembly comprises a woven steel and glass fabric wound on to a steel roller, powered by an internal 24 V d.c electric motor, enclosed within a 1.2 mm-thick (0.047 inch) stainless steel box.

There are two vision panels within the main curtain assembly and 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.

The barrier assembly has been tested to the requirements of BS EN 14600-5 for ‘Durability of Self-Closing’ (500 cycles on primary power and an additional 50 cycles using back-up power; closing speed of 0.08 m/s). The barrier assembly has been tested to the requirements of BS EN 1634-1 for ‘Fire Resistance’ (120 minutes integrity) and BS EN 1634-1 for ‘Radiant Heat Flux’ (30 minutes).

Features and benefits:

  • See through a deployed curtain as a means of escape.
  • Safely egress from lifts.
  • Suitable for lift lobby muster points.
  • First responder can clear a building faster.
  • First responder can see the presence of an occupant on the other side of a curtain.
  • First responder can see the presence of fire on the other side of a curtain.
  • First responder can see the presence of smoke on the other side of a curtain.


  • Escape routes incorporating doorways and corridors.
  • Lift openings and lobbies.
  • Areas where Fire Marshals and the Fire and Rescue Service may need to assess prior to entry.


The barrier assemblies move upon initiation of alarm or power or system failure, and fully deploy to the fire operational position within the range of velocities of 0.06–0.15 m/s (2.362–5.905 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.


Fabric type is EFP™ A1, which is a stainless steel wire reinforced glass fabric fire barrier. It has an area weight of 665 g/m² ±10%. The curtain fabric offers dimensional stability and is non-combustible to BS EN 13501-1 + A1 – Reaction to Fire.

The fabric has passed testing to BS 8524-1, BS EN 1634-1, BS EN 1363-1, BS EN 1362-2, BS EN 1634-3, BS 6853, BS EN ISO 1716, BS 476-6, BS 476-7, BS EN 13823 and BS EN 14184-1.
