SmokeStop evacU8

SmokeStop evacU8 is a walk through smoke curtain for high occupancy buildings. SmokeStop evacU8 is a unique patented bi-roller system which has narrow interweaving / overlapped panels which are only 600mm wide. Each panel overlaps the other and has its own self levelling bottom bar ballast system. Evacuees can simply walk through the ‘strips’ which then fall back into place, helped by the patented anti-tangle overlap retention system. The evacU8 curtain is also DDA compliant.

The SmokeStop evacU8 is generally used in conjunction with the SmokeStop smoke curtains as active smoke barriers and is applied as an intuitive way of escape in case of emergency.

Smoke Curtain Construction

Each smoke curtain has at least 2 rollers with each approximate 600mm wide fabric panel alternating between rollers. The rollers are positioned ‘side by side’ and deploy through the centre of the headbox.

Metalwork is zinc coated mild steel. This can be painted on site or powdercaoted to DULUX or RAL colours.

Operation

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. Once deployed, people can easily pass through the overlapping smoke fabrics. The smoke fabrics self close.

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.

 

Bottom Bar

Each fabric panel has a soft bottom ballast bottom detail for a soft edge which will not hurt people evacuating.
