VBS/FS240 - fire shutter
The FS240 is a fire shutter that is built to fulfil the more heavy duty demands associated with industry. It provides an automatic closure in the event of a fire in order to seal off an opening for a designated minimum length of time. For proven quality and built-in reliability, you can't improve on the FS240 as a heavy duty assistant to fire containment in industry.
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 3500m up to 4800mm will be traditional curved 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.
These electric fire shutters are available in 3 phase, 415volts, 50hz or 1 phase, 240 volts, 50hz. They are driven by a geared electric motor that has an integral controlled descent mechanism, emergency hand chain facility and push button starter. The shutter rate of descent is controlled through the gears being constantly engaged and the closure speed is approximately 100mm per second. The clutch can be reset and the door can be raised and lowered in a normal manner. Each motor incorporates a relay inhibitor to prevent the solenoid "burning out". The shutter auto-closes subsequent upon a 24v D.C. 0.5amp signal from the fire alarm. The motor unit has the facility to simulate a fire test via a pull and reset cord.
Also available is an Audio Visual Warning (FDI). Principally this unit is designed to delay the closing of the fire shutter. Generally the fire alarm is linked to the audio-visual unit and from the audio-visual unit into the solenoid. On activation from the fire alarm the unit starts to "Flash & Sound". This unit contains a programmable timer that effectively delays the signal to the solenoid to close the door, allowing a set amount of time for egress of personnel before closure of the shutter.
