GENERAL Even relatively small fire loads can generate large numbers of cubic metres of smoke which degrade visibility and health in a very short period of time. Supercoil automatic smoke curtains restrict the lateral spread of smoke and hot gases along the underside of a roof, ceiling or balcony within a building in the event of fire. They are used as part of a smoke control system to create smoke reservoirs from which smoke and hot gases can be extracted by smoke & heat release vents or smoke extraction fans. Venting smoke provides valuable time for occupants to escape and allows fire service personnel to find the seat of the fire for more effective fire fighting operations. Using Supercoil smoke curtains to create smoke channelling increases the efficiency of the system and provides a cost saving through minimising the requirements for exhaust system. Supercoil smoke curtains have been engineered to complement the building design, allowing architects and building designers to maximise and open up internal space sometimes critical in factories, warehouses and shopping centres for example. Its compact design means that it is easily integrated into existing buildings. Supercoil smoke curtains have been fully tested to EN12101.1 for 600Co for 120 minutes fire resistance and maximum allowable deflection. Typically, smoke curtains are not tested for smoke leakage. Refer to the Smoke Containment Screen sections of our catalogue for more information. This test does NOT represent compliance with AS1530.4.

Description Supercoil automatic smoke curtains consist of a compact header box and flexible curtain connected to a control system. The system is available with and without side guides and as a static, fixed in place curtain/baffle. Supercoil automatic smoke curtains contain a patented tensioning system to prevent potential binding of the curtain inside the header box, thus significantly reducing the potential for motor burnout and increasing the reliability of the system. The compact header box dimensions means this system can be easily integrated into existing buildings. Static smoke curtains are a cost effective alternative to automated systems when aesthetics or space is not of concern. For example; to create reservoirs at ceiling heights in factories, and warehouses. Refer to section 11 for more details. Operation The system is designed to activate on receipt of an alarm signal from the master fire control panel or our stand alone control system that allows up to 40 smoke detectors to be connected. As with all of our curtain and screen systems deployment is by gravity (gravity fail safe). The rate of descent is controlled mechanically to approximately 4.5m/min to significantly reduce the likelihood of injury to occupants that may be passing through. Fire and/or smoke curtain systems that do not have this gravity fail safe function do NOT comply with the B u i l d i n g C o d e o f A u s t r a l i a requirements for fail safe in the event of power failure. (Refer to BCA Clause C3.6 for example). Power failure can mean either a blackout type event or disconnection/damage of the electrical cable.
A 240 volt tubular motor which incorporates an electro-magnetic brake, adjustable mechanical upper and lower limits is used only to rewind the system on reset of an alarm or power. Battery back up is available as an option to reduce the likelihood of nuisance deploys in the event of a power failure but NOT essential to the effective operation of the system in fire mode. There is a complete range of control options and combinations to suit specific project functionality requirements including a basic trigger unit, preprogrammed master control and battery back up. Our office can assist with selection of the most cost effective control system to suit your needs. Each barrier can be individually operated from a low-level surface mounted key switch, push button or break glass. Other features include Safety Edge (system stops deployment if it hits an obstruction), audible and visual warning system and staged deployment.
Application Supercoil smoke curtains provide effective smoke channeling in large buildings, significantly reducing smoke and toxic gases from spreading, and allowing them to be extracted in a controlled manner.

Application cont... The system is also ideal for use in shopping centres to prevent smoke movement through voids containing escalators and/or stairs (as required by BCA Specification E2.2b) where limited head room or way finding requirements prevents the use of fixed systems. For Alternative Solutions designed by Fire Safety Engineers, Supercoil may be utilised to help accomplish the following objectives: • Keeping escape and access routes
free of smoke so people can recognize and identify signs / paths to safely egress
• Assist firefighting by providing a smoke-free layer
• To delay or prohibit the flashover and therefore the development of the fire
• Prevent damage from smoke channeling to ventilation systems
Each curtain can also include an escape door so the curtain itself does not impede any escape routes. Contact us for details as this option may not be suitable for all buildings. This options is NOT suitable for fire curtains for obvious reasons. Some examples in which Supercoil smoke curtains could be applied include: • Sports stadiums • Industrial buildings • Underground railway stations • Atriums
Sports Stadium Providing Supercoil smoke curtains in the stadium prevents the smoke from spreading and allows the controlled extraction of toxic gases.
Industrial Buildings Supercoil smoke curtains assist with providing a smoke-free, safe egress route for the occupants of the building during a fire and an effective smoke reservoir at the ceiling, keeping the smoke and toxic gases in an area which prevents damage to goods and increases natural smoke ventilation efficiency.

Underground railway station Egress in the direction of natural smoke movement creates unique problems for designers of underground buildings.
Supercoil smoke curtains prevent masses of smoke and toxic gases blocking occupant escape and assist with controlled extraction. Atrium Supercoil smoke curtains prevent smoke from entering the public corridor areas as its buoyancy flows straight up and out the exhaust vents within the ceiling.
Reliability The Supercoil smoke curtain can span up to 50m in a single module due to the patented drive system which eliminates multiple modules and curtain overlaps. This significantly reduces the number of motors and therefore increases the reliability and reduces the complexity of the controls.
Installation In line with Smoke Controls mission to provide customers with reliable solutions, the Supercoil system is installed by our fully trained and approved installer network.
Verification of performance The test protocol (EN12101.1) for ’smoke curtains’ is a modified fire test. There are several performance criteria in this test that the curtain system must meet. These include reliability, time/temperature testing and a prescriptive requirement for perimeter gaps to be no larger than 60mm and deflection to be no more than 15o. Also, EN12101.1 clearly states “As the objective of the general testing procedures is to establish the ability of the smoke barrier to achieve the product design and performance requirements and classification in its operational position, and to continue to act as a barrier to smoke and heat for a designated period of time, the complete product (i.e. including motors and fixings) to be installed shall be tested”. As there is no requirement for actual smoke leakage measurements in this test procedure, Fire Engineers should request published drawings for the product indicating the dimensions of gaps (leakage paths) as required by EN12101.1. Note that one of the key benefits of Supercoil’s large single span over modular systems is that it eliminates potential leakage paths at overlaps—which would otherwise typically occur every 6m. This enables the Fire Engineer to consider the use of larger smoke compartments or reduce fan sizes for example. However, attention should be paid in specifying Supercoil for these or similar reasons to ensure modular systems are excluded from the specification if they potentially impact on the reliability of the overall system.

Maintenance Annual maintenance and verification of system operation should be conducted by trained personnel in strict accordance with our documented procedures. Contact us for details. Technical Data Smoke curtain The Supercoil fabric is a specially reinforced coated fiberglass material with a Class 1 surface spread of flame rating when tested to BS476.6 and is able to withstand temperatures of in excess of 600˚C for 120 minutes when tested in accordance with EN12101.1. As with all of our smoke and fire curtain products the fabric is easily identifiable as a Smoke Control product due to the red stitching incorporated into the curtain. Bottom Rail A triangular section steel bottom rail is attached to the curtain and is designed to stop at ceiling level or into a recess in the box when raised. This section can be coloured as required. Ceramic coatings and other unique finishes can also be achieved. A self leveling bottom bar can also be supplied to completely conceal the bottom bar. Please contact us to discuss your requirements. Guides The system is available with side guides should there be a requirement that the curtain falls to floor level or where an increased pressure differential is envisaged. If there is no mechanical extraction and smoke compartmentation is required, we recommend the use of Fiberseal (section 2). Maximum Sizes 50m wide x 8.5m drop Operating Speed Approximately 4.5m per minute. Weight Typically 30kg per linear metre of width.
Freedom of design Integration into every architectural solution can be realised due to the amazingly simple and space saving installation. The metallic components of the system can be powder coated to any colour. Note: a super small head box is available for very tight ceiling spaces—approximately 200mm wide x 100mm high –but please contact us for details before specifying. Stability and smoke tightness If smoke protection solutions require smoke leakage performance, refer to the Smoke Containment Screens section of our catalogue. Note that side guides on “smoke curtains” may not provide a significant increase in smoke containment. Typically, this performance is not quantifiable. Side guides will however significantly reduce deflection due to pressure variation (e.g. due to smoke pressurization system) or mechanical extraction. Functional freedom Complicated installation situations, e.g. for the passage of crane beams, cable ducts or conveyor systems, virtually demand the Supercoil system. We are able to provide support with any difficult problems due to an extensive history of installations all over the world. Economy by intelligent planning The intelligent use of smoke barriers offers an especially economic solution to smoke protection problems. Typically, a reduction in the number of smoke vents and make up air vents can be reduced by using the Supercoil system to contain buoyant smoke in calculated reservoir sizes.
