FMB Fire Curtain

A Colt Automatic FireCurtain FMB is an automatic fire curtain which seals off an area to contain the movement of flames with a defined fire resistance time. Such curtains can also be partially deployed in the event of a fire to control the movement of gases from a fire within buildings before they are fully used for fire protection. It has been designed and tested according to BS 8524-1:2013, and achieves E180 and EW20 classifications.

It unrolls in a gravity fail safe manner without needing power (gravity fail safe). The fire curtain consists essentially of a roller in a galvanized steel housing, the roller comprises a flexible heat resistant fabric which is impervious to smoke and hot gases, wound around a tube. A heavy bottom bar fitted to the bottom edge of the fabric ensures that the curtain deploys as designed.

Following an exhaustive phase of rigorous testing, Colt is pleased to announce that its FMB Fire Curtain has been independently certified by IFC Certification (IFCC SDP11-02) to British Standard BS 8524, Parts 1 & 2. Certification to this standard insures that a Fire Curtain product is appropriate for market use and will function correctly under fire conditions. BS 8524 is the British Standard for Active Fire Curtain Assemblies. Part 1 is the specification for the product which specifies a thorough and exhaustive regime of testing for the product itself, whereas Part 2 is a Code of Practice covering application, installation and maintenance. BS 8524 Parts 1 and 2 cover all aspects of these products; from design, durability and reliability, to installation and maintenance.

In order to meet Part 1 the testing regime covers reliability life cycle testing, response time, fire resistance (integrity) testing, impact testing, hot motor cycling tests and factory production control inspections. The Colt FMB Fire Curtain successfully passed all rounds of testing.

To demonstrate compliance with Part 2, IFCC conducted an audit of our project management, installation, commissioning and maintenance processes to ensure that our teams are competent to deliver safe, robust and compliant installation.
