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.
» 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. CE Marked according to BS EN 12101 1:2005+A1:2006 Annex ZA with its Assessment and Verification of Constancy of Performance (AVCP) by Warrington Certification Ltd. 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.
