Fireflex Radiant Heat Reducing Shutter under test |
Tested by the Loss Prevention Council (Test Report 220737) to an integrity
of 240 minutes (4 hours) for openings up to 50 m².
Fireflex is an obvious choice where increased risk of fire is a major
concern. Fireflex provides a substantial safety barrier between the source
of the fire and any precious or dangerously flammable stock. Fireflex
is the perfect application for hospitals, shopping centres and industry.
Designed for internal or external applications where increased fire protection
is required. It provides radiant heat protection with reliable
operation through a simple control panel that can be adapted for a range
of activation methods.
Fireflex is power operated with controlled descent following automatic
activation. A safety brake is included as standard at the non motor end.
Due to its unique construction, the radiant heat levels around Fireflex
drop from 65kw m² to 2.7 kw m². This means that combustible
materials can be stored 500mm away from a 1200°C inferno, increasing
floor space and reducing risk and break down of fire compartmentation.
Fireflex R also has a weighted sound reduction of 18 dB (BS5821 Part 3: 1984).
General Specification
|
Fireflex Radiant Heat Reducing Shutter
|
Curtain
Manufactured from pre galvanised material designed to provide a hollow
section panel with ceramic infill. Each section is
100mm high with twin ribbed face for rigidity.
The curtain is held in position with purposely designed end fittings
which act as a curtain alignment system. The bottom panel
is terminated with a galvanised steel plate with horizontal and vertical slots.
Hood (Coil Casing)
All Fireflex R shutters include a galvanised sheet hood as standard with
optional motor cover. (Motor cover always included if less than 2500mm high).
Guides
Formed from pre galvanised steel.
Endplates
Mild steel of appropriate thickness relative to door size.
Finish
Standard finish to all parts is galvanised.
Powder coated finish to a standard range of BS/RAL colours available
at extra cost
Operation
Fireflex Shutters are power operated by a 3 phase & neutral motor
with various options of release:
Level 1 Fusible Link Operation
Normal operation by push button station or keyswitch with fuse link to
close shutter at local heat source of 75°C.
*Level 2 Alarm activation with manual reset
Normal operation by push button station or keyswitch with solenoid
release to close shutter following fire alarm signal with manual reset of
solenoid by pull cables.
*Level 3 Alarm activation with automatic reset
Normal operation by push button station or keyswitch with solenoid
release to close shutter following fire alarm signal with automatic
reset of solenoid once alarm is switched off by fully opening shutter.
*Level 4 Alarm activation with automatic reset and part close facility
Normal operation by push button station or keyswitch with solenoid
release to close shutter following fire alarm signal with automatic
reset of solenoid once alarm is switched off by fully opening shutter.
Shutter can also part close to act as a smoke curtain, fully closing
after an adjustable delay. Shutter must have maintained supply for this
function.
*For Level 2, 3 and 4 Audible Visual (with adjustable delay timer) can
be included to one or both sides of the opening.
 
Fire Alarm requirements
The Fire Alarm circuit must provide the supply for the 24v DC solenoid
(0.5 amps) with an initial supply of 3.5 amps for 20-30 m/seconds to
release the shutter but only when in the alarm condition.
If the fire alarm is unable to provide a 24v DC supply a battery back
up system is available at extra cost.
The 24v DC supply needs to be provided separately from that of the fire
alarm system as under the requirements of BS5839 Clause 19, the
connection of such equipment is specifically prohibited.
Syston Doors DO NOT include for connecting into the fire alarm circuit.
Note! To comply with current legislation fire shutters cannot be linked
to fire alarm systems if they are over fire exits or are on a fire exit route. They
can only be fitted with a device, which will close the shutter, by a local heat source
i.e. fusible link.
