FireMaster® Plus² - Vertical Active Fire Curtain

An electrically operated active fire curtain barrier assembly. Active fire curtain 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 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. Has 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). Has been tested to the requirements of BS EN 1634-1:2014 for ‘Fire Resistance’ (180 minutes integrity). Has been tested to the requirements of BS EN 1634-1:2014 for ‘Radiant Heat Flux’ (90 minutes).

Operation:

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. At the end of the period, the barrier assembly will deploy.

Fire resistance:

180 minutes (3 hours) integrity.

Period of radiation:

107 minutes <15 kW/m².

Classification:

E180 EW90 C0 (single).
