Active fire curtain barrier assembly comprising technologically advanced fire-resistant fabric barriers encased in a compact steel housing, available in open shapes to be used in conjunction with side channels. 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.

Applications include atria, escalators and stairs, and will remain hidden within the ceiling until deployed.

Operation:

The barrier assemblies commence movement upon initiation or any initiation, power or system failure and move to the fire operational position with site specific adjustable and synchronized velocities within the range of 0.06–0.15 m/s using the unique VarioSpeed™ function.

In the event of mains power failure, they remain retracted using their own dedicated battery back-up power supply for a pre-determined period (nominally 30 minutes). If signalled to descend during this period, they fail-safe by gravity in a controlled manner to their fire operational position. At the end of the pre-determined time delay they fail-safe by gravity in a controlled manner. This safety feature is essential to avoid dangerous guillotine/ free-fall deployment.

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).

Standards:

Compliant to PAS 121:2007 (where applicable).

Warranty:

One year.

Options

Size (maximum):

Available in unlimited widths and drops up to 8.0 m.

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.

Concealment:

A range of ceiling interfaces are available and can even invisibly conceal the barriers in the ceiling whilst still allowing access for service and maintenance. All systems remain totally concealed when non-operational.

Fixing:

Fixing options to suit all types of ceiling configuration are available (can be integrated with both solid and suspended ceilings and will remain hidden within the ceiling until deployed).
