To answer the growing demand for a safe working environment,
REFLEX™ has incorporated the SMOKE STOPPER smoke
containment product into the already extensive range of REFLEX™
automated, environmental control blinds and screens.
|
|
 |
| |
In the design of public buildings and other highly populated
defined spaces where there is any possibility of the threat of
smoke or fume generation, consideration must be given to the
safe escape of the occupants. To be able to automatically contain
or redirect the flow of fumes or smoke within a confined area is
the purpose of the REFLEX™ SMOKE STOPPER. Designed
to be permanently hidden within the ceiling cavity of any given
thoroughfare and to be activated in concert with electronic fire
warning systems, the flame proof screen will automatically lower
to a predetermined height above FFL to allow the egress of
occupants while stopping the progress of smoke spread to that
area.

The REFLEXTM SMOKE STOPPER is an electrically operated
roller screen, sealed within a heavy steel cassette which is
installed within ceiling cavities in conjunction with a cavity smoke
sealing system. When activated, by the fire management system,
a flame proof, textile screen will lower to either one of the two
possible preset positions.
The casing of the cassette shall be 2 mm mild steel with Galvabond
coating. Casing dimensions are 165 mm wide and 180 mm high.
End plates of the cassette shall be 8 mm thick mild steel with
blue zinc plated finish to prevent corrosion. These end plates also
serve as mounting points for the internal fabric storage roller and
drive motor.
Maximum span for a single cassette is 5,000 mm.
Mounting cross bars shall be spaced at approximately 2,000 mm
centres and 500 mm from each end of the cassette.
Approximate weight of the complete system is 25 kgs/metre.
When the blinds are mounted abutting a vertical wall, side edge
guides are available as an option to complete the total smoke seal
to the three sides (top, left and right).
The flame proof fabric shall be a continuous filament, fibreglass
based, sealed woven cloth with zero particle penetration. Colour
shall be silver grey to both sides.
Fabric thickness shall be 0.46 mm (nominal) and weight is 0.543
gsm (nominal). The fabric shall be stored when not in use by axial
rotation onto the 127 mm aluminium roller. This roller shall be made
from 6106 T6 extruded aluminium and is in one piece. Fabric shall
be fixed to the roller both chemically and mechanically. The fabric
hem rail shall be extruded, natural anodised aluminium in a profile
to suit.
An internal asynchronous digitally controlled AC motor shall drive
the fabric storage roller in each individual system and lower the
screen at approximately 8 seconds per metre when commanded
by the management system via dry contactors for extend/stop/
retract control.
The circuitry allows for three predetermined hem positions
- Fully retracted which may be the ceiling level or fully retracted
into the cassette.
- Intermediate – which may be used as “egress height” or
evacuation level (900 mm above F.F.L).
- Fully extended – which would be to floor level as required.
Control wiring shall be four core flat cable and RJ11 phone type
connectors. Multiple blinds can be wired in series or parallel with
no extra control components.
Standard 240 volt power should be supplied to each screen by
incorporating a UPS within the supply circuit. (Specifications
available separately, are dependent on individual installations and
control systems).
Minimum width = 1,000 mm
