Flame Shield 240
Designed for use where the tube motor operated fire shutter
is not suitable. Providing 30, 60, 120 or 240 minutes
of protection from fire, this shutter has been tested to BS476 Part 22.
Flame Shield 240 provides fire protection for all uses including department
stores, shopping centres, warehouses, factories,
schools and all other areas where protection from the spread of
fire is required.
Fixing to Partitions
Flame Shield 240 can be fixed to non-load bearing
timber or steel framed partitions up to 2750mm wide x 3250mm high
(Maximum area 10m² ) up to 60 minutes.
Shutter curtains are constructed from 76mm curved section
steel laths, which are securely held in place by end locks.
Lath thickness varies dependant on opening size and fire rating.
Bottom rails are roll formed galvanised Tee sections.
Hood (Coil Casing)
All fire shutters as standard include a galvanised sheet
steel hood (coil casing).
A motor cover will be included on all shutters under 2500mm high and optionally over this
65mm x 3mm (minimum) mild steel channels mounted
on rolled steel angles.
Mild steel of appropriate thickness relative to
Type of Operation
Available up to 4000mm wide x 4000mm and suitable for applications
where the shutter is held open, closing only in the event of a fire.
Manual closing is achieved by releasing a pull cord, which allows a controlled
descent via a gear unit at approximately 100mm/second.
Opening by means of a hand chain
Operating by the hand chain is a slow process and power operation is
recommended when everyday use is required.
Suitable for all sizes of shutter, the motor is either single phase
(240 Volt 50 Hz) or 3 phase (415 Volt 50 Hz) dependent on size of door.
A controlled descent of 100mm per second (approx.) is an inbuilt safety feature.
In the event of power failure, manual override is achieved by pulling a pull
cord to close the shutter under controlled descent and a hand chain to open.
The handchain override is designed for emergency use only.
As standard each shutter will include an open/stop/close push button
station mounted on the motor side at approximately 1500mm above the
finished floor allowing sight of the shutter during normal operation.
Other control options available are shown under 'Options'.
All switchgear unless otherwise stated are surface mounted.
Modes of Activation
Self closing by means of a thermal fusible link activated at a temperature
of 68°C and mounted to the underside of the hood
24v DC auto resetting solenoid release device connected to the
fire alarm/smoke detector.
Solenoid automatically resets when the shutter is fully opened by
pressing the 'up' button and when the alarm has been turned
(On hand chain operated shutters the solenoid is reset manually
by pulling on a cable).
Syston Doors do NOT include for connecting into the fire alarm.
The fire alarm circuit must provide the supply for the 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 circuit is
unable to provide a 24v DC supply for the solenoid or ancillaries a battery back-up
system can be provided at extra cost).
Note! To comply with current legislation fire shutters cannot be
linked to fire alarm systems if they are over fire exits or cover
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
All as Option 2 but with mechanical fusible link back up.
