FireMaster® NVS™ Horizontal Duplex™
Description

Active fire curtain barrier assembly that closes from each end of a void to meet and shut in the middle, comprising technologically advanced fire-resistant fabric barriers encased in a compact steel housing. Barriers remain invisibly retracted until activated by an alarm or detector signal, at which time they descend safely to their fire operational position.

To be compliant, fire barriers must be protected from a short circuit and or total power failure, this is achieved with the patented Total Gravity Fail-Safe (TGFS) system. Fire barriers will control the spread of fire in a building. It is suitable for large openings including expansive atria.

Operation:

The barrier assemblies commence movement upon initiation and move to the fire operational position with site specific adjustable and synchronized velocities within the range of 0.06–0.30 m/s using the unique VarioSpeed™ function. The barrier has fail-safe with controlled braking system and drive mechanisms.

Rollers:

The rollers are mounted and are driven by tubular motors. The rollers are enclosed in a steel housing and the leading edge of the curtain fabric has a supporting bar spanning between the side channels that retain the barrier.

Fabric:

Fabric type is EFP™ 4/1000, a glass fibre, stainless steel wire reinforced, fabric coated with a micronized aluminium filled fire retardant polyurethane, nominal 690 g/m². It is in compliance with the requirements of Class 0 to meet the statutory guidance in Building Regulations (E&W) Approved Document B (Volumes 1 and 2).

Side channels:

Side channels seal the curtain fabric and the building. Fire can cause extreme positive or negative pressures (up to 20 Pa). Side guide channels are constructed from galvanized steel (available in standard RAL colours) that can be either surface mounted or recessed into the wall structure to give a flush finish.
