Fire Shutters // A1 Shutters Flameshield 120
For commercial applications, the Flameshield 120 Commercial Fireshutter has it covered
In the past, choosing a fire shutter has been about selecting the right one for job - but now the Flameshield
120 commercial fire shutter has been developed to enable the aesthetics of the application to be taken into
consideration. For commercial applications, like receptions and serveries, for example, the clean lines and
internal motor of the Flameshield 120 commercial fire shutter provide a stylish solution to fire safety demands.
The Flameshield 120 commercial fire shutter was successfully tested at the Warrington Fire Research
Establishment and is constructed to WARRES No.145904 - the test is in accordance with clause 8 of
BS476 part 22: 1987.
Fire relay and key switch (requires maintained supply, battery back up needed if no maintained supply).
Fire relay, key switch & fusible link (requires maintained supply, battery back up needed if no maintained supply), fusible link if no fire alarm.
Principally the commonly used means of release, the characteristics mimic the use of the solenoid on the
conventional fireshutter, again linked to the fire alarm, the shutter rather than closing manually through the
gearbox will of course be powered down. A volt-free signal is required from the fire alarm.
FUSIBLE LINK RELEASE
On activation the link, which is a soldered link, separates and releases at 64° centigrade, in effect the
temperature release of the link creates a signal to the relay which in turn powers the door down.
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 straight into the key switch. There is no need for a separate relay; there is already a relay in the FDI. On activation from the fire alarm the unit starts to "flash & sound", this unit contains a programmable timer which effectively delays the signal to the relay in the panel to close the door. 230mm wide x 240mm long x 120mm deep.
The shutter test relates to 1HR / 2HR fire resistance. The shutters are generally intended for protection of a
range of openings in masonry or 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 square metres,
principally this incorporates the BRE test FG7941N which 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 curved 75mm lath construction, based on a maximum area of 10 square metres.
Shutters under 4000mm clear width will have 50mm guides and shutters over this width will have the traditional 65mm guides.
BATTERY BACK UP UNIT
Principally the tube motor fire shutter requires a maintained supply, if this cannot be achieved then effectively
the shutter will require a battery back up unit. Fundamentally if under fire conditions there is a power failure, the
shutter must have a means of ensuring closure, the unit provided will give the facility for at least one operation
under fire conditions. The dimensions of the battery backup are 200mm wide x 130mm long x 70mm deep.
PAINT FINISH OPTION
To compliment the aesthetics of your application, this product can be powder coated to any BS or RAL colour
(subject to availability).
