An electrically operated active fire curtain used to form a virtually continuous barrier as a fire separating element.
Suitable to be used to form a virtually continuous barrier as a fire separating element and for use in cleanroom environments such as:
An electrically operated active fire curtain. The barrier assemblies comprises 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.
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’ (120 minutes). The barrier assemblies have been tested for Air Cleanliness to ISO 14644-1, achieving a Class 6 rating. The barrier assemblies have been tested for Chemical Resistance to ISO 4628-1 and VDI 2083 Part 17.
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.
