VBS/FS120 - fire shutter
The FS120 is a fire shutter that has been developed with aesthetics in mind. By virtue of its uncompromising duty and heavier construction, a fire shutter's looks have never exactly been the issue. Here, however, is a fire shutter with clean lines to suit that kitchen servery or reception counter.
Successfully tested at the Warrington Fire Research Establishment, it is constructed to WARRES No. 145904 - the test is in accordance with clause B of BS476 part 22: 1987.
Size Parameters: The shutter test relates to the 1HR/2HR fire resistance. The shutters are generally intended for protection of a range of openings in masonry / concrete, steel, steel stud or timber partitions. The maximum clear openings are for 4000mm wide x 2500mm high, or in a partition system for 1 hour up to an area of 10 sq. m. Principally this incorporates the BRE test FG 7941N that relates to a tested fire shutter in a stud partition. The opening must be fire rated to suit and be capable of carrying the weight of the shutter. Where the shutters are used to protect serveries it is assumed that the counter is composed of non-combustible material and the counter is of sufficient width to ensure that the bottom rail movement under heating cannot result in the rail overhanging the counter. Shutters over 3500mm up to 4800mm will be traditional scrolled 75mm lath construction, based on a maximum area of 10 sq. m. Shutters under 4000mm clear width will have 50mm guides and shutters over this width will have the traditional 65mm guides.
Unlike the FS240 that closes manually through the gearbox under its own weight, the FS120 is powered down following a volt free signal from the fire alarm. In case of power failure, the system is installed with a battery back-up unit.
The shutter may be powder coated in a RAL or BS colour of choice (subject to availability)
