SmokeStop is an automatically deploying smoke curtain designed to control the spread of smoke in a building.A smoke curtain is a device that controls the movement of smoke during a fire by directing the smoke towards mechanical or natural ventilation points. Traditionally smoke curtains have been used as an integral part of a naturally ventilated building however smoke curtains are proving to be a cost effective solution in conjunction with mechanical ventilation.
The SmokeStop Active Smoke Barrier is an automatic smoke curtain which comprises of technologically advanced fire-resistant fabric roller barriers encased in a compact steel housing.
Smoke Curtain Construction
Each roller is up to 5m wide with multiple roller construction up to unlimited widths. Maximum size single roller construction is 6 metres wide x 8 metres high.
Metalwork is zinc coated mild steel. This can be painted on site or powder coated to DULUX or RAL colours.
A 24v electromagnetic brake holds the fire curtain open. Closing is by gravity at a controlled speed of 0.06 – 0.15m/s. Opening is driven by one or more 24vDC tubular motors mounted within the barrel.
Test is performed by a simple key switch operator. The system is reset manually by pressing the reset button on the control panel. Automatic reset is available.
Standard bottom bar is Jumbo which is a triangular shaped bar 40mm wide. Also available is the ‘T’ bar and operable ceiling interface systems (SLAT) in 150mm and 75mm profiles.

Side Guides and Edge Gaps
Side guides are only required if the designer requires a 0mm edge gap at the sides. Standard side edge gap for SmokeStop is 20mm and the headbox edge gap is 0mm. For longer drop smoke curtains the edge gap could be as large as 60mm.
