FireMaster® A1 ResQ-Window

Application

Suitable for use as:

  • Escape routes incorporating doorways and corridors.
  • Lift lobby muster points, lift openings and lobbies.
  • Areas where fire marshals and the fire and rescue service may need to assess prior to entry.


Suitable to be used to form a virtually continuous barrier as a fire separating element.

Description

An electrically operated active fire curtain barrier assembly. The barrier assemblies 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 stainless steel box. Within the main curtain assembly there are two vision panels. 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 assemblies have been tested to the requirements of BS EN 14600:2005 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 assemblies have been tested to the requirements of BS EN 1634-1:2014 for ‘Fire Resistance’ (120 minutes integrity). The barrier assemblies have been tested to the requirements of BS EN 1634-1:2014 for ‘Radiant Heat Flux’ (30 minutes).


Operation:

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:

120 minutes' (two hours) integrity.


Period of radiation:

Greater than 30 minutes (for a radiation level measured below 15 kW/m²).


Classification:

E120 EW30 C1.


Product certification, performance and/ or testing:

  • Complete barrier assemblies are certified by an independent accredited certification body operating to ISO/ IEC 17065:2012.
  • Complete barrier assemblies have been tested for fire resistance to BS EN 1634-1. The barrier assembly achieved 120 minutes integrity and 30 minutes radiation.
