Application

(Picture shows optional key lock)

 

'Flameshield 120' 240v single phase tubular motor operated fire shutters provide an attractive and space friendly fire shutter solution with a fire resistance as standard of up to 120 minutes (2 hours) and for openings up to 4800mm wide x 1700mm high (see size grid).

The shutter is constructed to Warrington Fire Research Centre WARRES No. 145904, the test is in accordance with clause 8 of BS476 Part 22.

The attractive 50mm flat faced lath for openings up to 3500mm wide x 2500mm high make it most suitable for servery type openings or where aesthetic appearance is important.

Over this size a traditional 76mm curved lath is used but still offers the benefits of a space friendly coil casing and guide detail.

General Specification

Curtain
Shutter curtains are constructed from 50mm flat faced laths up to 3500mm wide x 2500mm high or 76mm traditional curved laths over this size, with a standard Tee bottom rail. (If smaller openings are adjacent to larger openings the laths on the smaller openings would normally be 76mm to ensure all match).

Hood (Coil Casing)
A profiled galvanised sheet hood is included as standard. A fascia can be included at extra cost on fit within applications.

Dependent on the fire rating of the shutter and the size of the opening, the shutter could require a hood support bracket.

Guides
Vertical guides are fabricated from 50mm deep galvanised steel channels. Wider openings will use 65mm deep channels.

Finish
Standard finish is curtain, bottom rail, guides & hood galvanised, end plates and fixing angles are finished in one coat of primer paint.

Powder coated finish to a standard range of BS/RAL colours available at extra cost.

Locking
A lock is not normally included. A centre bottom rail key lock which sends a bolt into each side guide can be included at extra cost.

Operation

Powered by a single phase 240v tubular motor with normal day to day operation of the shutter by rocker switch.

Manual override by hand crank can be included at extra cost.

Available Modes of Activation

Fusible Link release
On activation of the fusible link from a local heat source of 68°C this will send a signal to the relay which will signal the shutter to power down from the maintained supply or alternatively from the optional battery back up unit.

Fire Alarm link
By use of a fire alarm relay the shutter will close under power. The unit will require a maintained supply or alternatively we can supply with a Battery Back Up unit.

Volt free fire alarm signal required.

Syston Doors do not include for connecting into the fire alarm system.

Audio Visual Warning Closure
For use when an audio & visual warning is required of the shutter closing. The unit also includes a facility for a delayed closing of the shutter. The fire alarm signal is connected directly into this unit. On activation from the fire alarm the unit starts to flash & sound with the shutter closing after a pre-determined delay (10 - 240 seconds).

Fixing to partitions

Flameshield 120 can be fixed to non-loadbearing timber framed or steel framed partitions up to 2750mm wide x 3250mm high (maximum area 10m²) up to 60 minutes under cover of the above certification.

For larger openings see our 'Flame Shield 240' range of fire shutters.

'Flame Shield 240' Electrically Operated Fire Shutter

Application

 Flame Shield 240
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.

General Specification

Curtain
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 height.

Guides
65mm x 3mm (minimum) mild steel channels mounted on rolled steel angles.

Endplates
Mild steel of appropriate thickness relative to door size

Type of Operation

Hand Chain
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.

Electric
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

Option 1
Self closing by means of a thermal fusible link activated at a temperature of 68°C and mounted to the underside of the hood

Option2
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 off.

(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

Option 3
All as Option 2 but with mechanical fusible link back up.

Size Parameters

  • Chain operated 4000 x 4000mm
  • Power operated 7000 x 7000mm
  • Larger sizes available on application

Self-Coiling Fire Shutter

Application

 Self-Coiling Fire Shutter
Self-Coiling Fire Shutter

 

Designed for smaller openings the Syston Doors self-coiling fire rolling shutter has been tested by the Loss Prevention Council (Report No.TE6697) and assesed by the BRE, Certificate CC10571, and can be face fixed or fitted within the opening.

Operating via a counterbalanced sprung roller the shutter will close automatically by fusible link at 68°C closing by means of a weight bar under gravity.

If the fire shutter is to be released via a fire alarm signal please use our Flameshield 120

*Maximum size: 1800mm clear width x 2100mm clear height.

General Specification

Curtain
Shutter curtains are constructed from 50mm flat faced laths with a standard Tee bottom rail.

Hood (Coil Casing)
A galvanised sheet steel hood is included as standard. A fascia can be included if required at extra cost.

Guides
Vertical guides are fabricated from 50mm deep galvanised steel channels.

Locking
Standard locking is by bottom rail mounted shootbolts. Cylinder key operated locks are available at extra cost.

Finish
Standard finish is curtain, bottom rail, guides & hood/fascia galvanised.
Powder coated finish to a standard range of BS/RAL colours available at extra cost

*N.B. The maximum clear opening height available with a push up fire rolling shutter is 2100mm. Above this size an electrically operated shutter must be used. Manual shutters can be used for normal security but will be heavier to lift than non fire rated shutters. This should be considered if doors are used regularly. For controlled descent and ease of use we recommend electrically operated fire shutters.
