Fire Curtain - FireMaster® NVS™ Simplex Horizontal - Horizontal Active Fire Curtain - Horizontal Active Fire Curtain

An electrically operated active fire curtain barrier assembly. The barrier assemblies comprises a fire-resistant fabric wound on to a steel roller, powered by an internal 24 V d.c. electric motor, enclosed within a 1.2 mm-thick mild steel box. 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.

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 ten cycles using back-up power; closing speed of 0.06 m/s). The barrier assemblies have been tested to the requirements of BS EN 1634-1:2014 + A1:2018 for ‘Fire Resistance’ (120 minutes integrity). The barrier assemblies have been tested to the requirements of BS EN 1634-1:2014 + A1:2018 for ‘Radiant Heat Flux’ (20 minutes).

Operation:

Barrier assemblies commence movement upon initiation of BMS alarm or power or system failure, and fully deploys 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:

120 minutes (2 hours) integrity.

Radiation resistance:

20 minutes.
