The smoke ventilation system at Johannesburg’s recently opened Mall of the South shopping centre is using SE Controls’ window automation, vents and control panel solutions to ensure it operates perfectly in the event of a fire, allowing smoke-free escape routes to be maintained for shoppers and staff.
Due to the large open plan areas within the mall and the high volumes of people, effective smoke ventilation is essential to ensure escape routes are kept clear if a fire should occur. As a result, the system uses 62 Curvent International vents and 20 x SE Controls’ SECO N 24 40 twin chain actuators, as well as 12 x 24 Volt dc OS2 controls panels and 8 x manual control point (MCP) switches.
Working closely with smoke control specialist, Curvent International, the system, which also uses roof mounted fans to help vent smoke from the mall, is controlled centrally by a repeater panel located in the main security office to provide additional safety and peace of mind.
In the event of a fire, the mall’s smoke sensors trigger SE Controls’ EN12101-10:2003 compliant control panels and chain actuators to automatically open the window and ventilators, allowing smoke to be vented to assist escape. Manual Controls Point (MCP) switches are also incorporated within the design to allow manual actuation of the system.
