SmokeStop DH120 Smoke Curtain

An electrically operated active smoke curtain barrier assembly. Smoke curtain barrier assemblies comprises a metallic fabric wound on to a steel roller, powered by an internal 24 V d.c. electric motor, enclosed within a 1.2 mm (0.047 in) stainless steel box. A bottom bar is fitted to the bottom edge of the curtain providing tension to the curtain with sufficient weight for the curtain to ‘fail-safe by gravity’. The 24 V motor contains an electromagnetic brake to arrest motion of the curtain when in the open position.

Features and benefits:

• The barrier assemblies have been tested to the requirements of BS EN 12101:2006, Annex B for ‘Reliability and response times’ (1000 cycles on primary power and an additional 50 cycles using back-up power; closing speed of 0.15 m/s).
• The barrier assemblies have been tested to the requirements of BS EN 12101:2006, Annex C for ‘Permeability of materials to smoke’ (0.3 m³/h/m²).
• The barrier assemblies have been tested to the requirements of BS EN 12101-1:2006, Annex D for ‘Temperature/ Time Resistance Tests’ (120 minutes integrity).
