Developing the Flameshield range
is yet another example of innovative product design and development,
with two fire shutters to cover both commercial and industrial use.
Flameshield 120 Commercial
Shutter: In the past, choosing
a fire shutter has been about selecting the right one for job -
but now A1S has developed the Flameshield 120 commercial fire shutter
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
Release Mechanisms:
Fire relay and key switch (requires maintained supply, battery back
up needed if no maintained supply). Fire relay, key switch and fusible
link if no fire alarm.
Fire
Relay: Principally the commonly used means of release,
the characteristics mimic the use of the solenoid on the conventional
fire shutter, 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 degrees 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.
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 10sq mtrs, principally this incorporates the BRE test FG
7941N 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 10sq mtrs.
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.
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 power coated to any BS
or RAL colour (subject to availability)
Flameshield 240 Industrial
Fire Shutter: This fire shutter
is designed to provide a heavy duty solution for industry and is
a popular option for a wide range of industrial applications.
So if you’re looking for
proven quality and built-in reliability when it comes to meeting
fire safety demands the Flameshield 240 industrial fire shutter
is the heavy duty solution for industry. This still remains a very
popular product, as it is perfect for a wide range of industrial
applications.

(requires maintained supply, battery back up needed if no maintained
supply). Fire relay, key switch and fusible link if no fire alarm.

Electrical
Operation: All electric fire shutters are available
in 3 phase, 415volts, 50hz or 1 phase, 240 volts, 50hz. The shutters
are driven by a geared electric motor, which 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, 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" Activation is generally
by means of a fusible link, solenoid release or both. Units available
in 1 phase or 3 phase. The motor unit has the facility to simulate
a fire test via a pull and reset cord.
Self
Coiling Operation: All manual fire shutters are
designed that the door should be left in the open position and close
only under fire conditions. The self coiling manual fire shutter
is under sprung so that it closes in the event of a fire. The self
coiling shutters have secondary guide channels to govern a drop
bar: this falls under its own weight once the fusible link has been
activated.
Maximum overall shutter
size 2850mm wide x 3000mm
high.
This manual fire shutter is designed to be left in the open position
and close under fire conditions.
Frequent use is not recommended, the shutters are under sprung to
enable the door to close quickly under fire conditions.
Activation of this door is by means of fusible link only, this is
a soldered link designed to melt at 68 degrees centigrade, this
releases the drop bar and closes the door under its own weight.
Modes of Activation
Fusible
link Release: On activation, the link which is soldered
link separates and releases at 68 degrees centigrade, on the manual
shutter this will release the drop bar and the shutter will close
under its own weight, on the electric shutters the manual brake
release is activated and the shutter will close under a controlled
manner.
Manual Solenoid Release:
All solenoid release mechanisms
are designed to be linked into the fire alarm, the signal required
from the fire alarm is 24 volt D.C. 0.5 amps on activation. The
signal from the fire alarm will trigger the manual brake release
and allow the door to close under a controlled descent.
Auto Solenoid Release:
Again. this is linked to the
fire alarm and the signal required from the fire alarm is 24 volt
D.C. 0.5 amps. This is the most commonly used activation allowing
for frequent testing and re-setting, when the door is returned to
the open position (after removal of the fire signal), the solenoid
can be automatically reset.
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 which effectively delays the signal to the solenoid to close
the door.
