Roller Shutters
2 Hour Fire Shutter
——————————
The 2 Hour Fire Shutter is ideal for applications where there is high risk of fire or where open areas can channel the fire out of control. The Fire Shutter closes automatically when activated to prevent the fire from spreading into the adjacent area. It is commonly used for shopping malls, fire curtain dividers, supermarket entries, warehouses, office buildings and flammable storage buildings. Fire Shutters are highly recommended where flammable materials are present.

Certified Testing
Tested by CSIRO Division of Building Construction & Engineering in accordance with Australian Standard 1530, Methods for fire tests on building materials, components and structures, Part 4 – 1990, Fire resistant tests of elements of building construction.

Door Dimensions – Standard
Maximum Height: 4000mm*
Maximum Width: 5000mm*
*Total door size must not exceed 20m².

Door Dimensions – Oversize
Maximum Height: 4300mm*
Maximum Width: 8000mm*
*Total door size must not exceed 28m².

Curtain – Standard 
The curtain shall be manufactured using 75mm by 0.8mm thick roll-formed galvanised interlocking steel slats. Each alternative slat shall be fitted with steel end clips to form a 2 hour rating curtain.

Curtain – Oversize
The curtain shall be manufactured using 75mm by 1.0mm thick roll-formed galvanised interlocking steel slats. Each alternative slat shall be fitted with steel end clips to form a 2 hour rating curtain.

Finish
The curtain and guide channels shall be fabricated from galvanised material. All remaining components shall be given a coat of zinc rich Grey primer.

Bottom Rail – Standard
The bottom rail shall be manufactured using mild steel angles of not less than 40mm by 40mm and 2.5mm thick bolted to back with the last slat sandwiched between the angles. The bolts shall not be less than 8mm diameter and fixed at not less than 300mm centres. Two lifting handles shall be fitted to the bottom rail on either side of the shutter centre.

Bottom Rail – Oversize
The bottom rail shall be manufactured using mild steel angles of not less than 40mm by 40mm and 4mm thick bolted to back with the last slat sandwiched between the angles. The bolts shall not be less than 8mm diameter and fixed at not less than 300mm centres.

Automatic Closing
In the event of a fire the door shall automatically close in order to prevent flame spread. The fusible link (rated at 80°C) fitted below the roller drum at one end is connected to a spring loaded automatic release arm. The release arm shall activate the automatic release/push down spring allowing the door to automatically close.
The roller drum automatic release shall be fitted with a specially designed automatic controlled descent governor to match the door size and weight.
The governor shall be designed to provide an average speed of between 250mm-300mm per second.

Smoke Detectors and/or Automatic Reverse (Optional)
Fire resistant Roller Shutters may be wired in conjunction with smoke detectors and fitted with an Automatic Reverse Touch Sensor strip where required, or specified.

Labeling/Compliance Certificates
The fire resistant Roller Shutter shall be labeled by using a metal steel tag being 50mm by 25mm. The tag shall be stamped with the manufacturers name, fire resistant rating, door number, year of manufacture. The metal tag is to be riveted to the bottom rail.
On completion and testing of the fire resistant shutter, the manufacturer shall supply a certificate of compliance, stating that inspection of the installation has been carried out and complies with the standards and/or specifications.
This certificate shall be passed on to the owner or builder to be forwarded to regulating authorities. NOTE: A minimum headroom of 800mm is required to comply with fire test authorities.

Operation
Roller Shutters operate by means of a flexible curtain guided in steel tracks and revolving on a roller drum. Hand operation is not recommended for shutters over 2200mm height, 3000mm width or 6m².

Chain Operation
Gearing shall be fitted to one end of the Roller Shutter and matched to suit door size and weight. Chain operation is not recommended over 16m²
