SmokeSafe is enclosed within a zintec steel headbox and this structure is rated at the same temperature as the curtain fabric. Removable cover plates are incorporated to allow access to the curtain rollers. A suitably weighted bottom bar is provided to prevent deflection and ensure correct operation under gravity.
Smoke barriers in their fire operational position will provide essential smoke containment and channelling and shall be defined according to their application type.
When smoke is detected the alarm sends a signal to the SmokeSafe system controller. The SmokeSafe starts to descend to its operational position to a designed/specified height from finish floor level. All smoke and heat control systems assist the protection of the means of escape.
Function of Active Smoke Barriers
• To create a smoke reservoir by containing and limiting the travel of smoke
• To channel smoke in a pre-determined direction
• To prevent or retard smoke entry into another area or void
SmokeSafe is designed with operational gaps at the sides, between the smoke barriers and the construction work of up to 20mm, 40mm and 60mm depending on the barrier movement from 2m, 2m up to 6m and 6m and over, respectively.
The system has a fire resistance performance in accordance with Annex D, achieving a D600A classification in accordance with BS EN 13501 4:2007+A1:2009 (600°C, over 120 minutes) when tested in accordance with BS EN 1363-1:2012.
Reliability, response time and durability tests were carried out in accordance to Annex B to determine the durability of the system. The SmokeSafe D120 system is designed to operate to more than 3 000 cycles (the standard only requires 1 000 cycles) at normal ambient temperatures to Category ASB1 and ASB2.
Air permeability tests in accordance with Annex C specifies that the leakage rate when tested is less than 25m³/hr per m² when tested in accordance with BS EN 1634 3:2004. The tested results at 25 Pa under positive pressure resulted as 2.09m/³ per m², under negative pressure at -25 Pa resulted as 1.85 m/³ per m² all at ambient temperature.
The fabric curtain weight is around 455g/m2 and is coated with a fire-retardant polyurethane on both sides providing a heat reflecting surface. The fabric has a nominal thickness of 0.4mm and is a 4-satin shaft weave.
The fabric has been independently tested for reaction to fire in accordance with BS EN ISO 1716:2010 and BS EN 13823:2010+A1:2014, achieving a classification of A2-s1, d0 in accordance with BS EN 13501 1:2007+A1:2009.

Over a number of years Smoke & Fire Curtains Ltd. have invested heavily in
new production techniques and innovative developments. Although development
work and fire testing certification can be a very long and very expensive
process we continue to develop new fire curtain systems in order to improve
and develop further our own systems in design. In 2019 we were recognised
for our innovation and were winners of the Leicester Mercury Business Awards
collecting the Freeth’s Award for Excellence in Science and Technology.
