Environment sensors, controls solutions and actuators from SE Controls Africa are helping create a safe and comfortable environment in The Link building at the Netcare Christiaan Barnard Memorial Hospital in Cape Town, as part of its combined smoke control and environmental ventilation system
The Link is the latest addition to the Netcare CBMH complex, which provides sub-acute, renal and pathology labs, as well as operating theatres and physiotherapy on its seven floors.
As part of the hospital’s design, The Link’s main atrium and second-floor walkway incorporate a combined smoke control and environmental ventilation system. This not only keeps corridors and escape routes clear of smoke in the event of a fire but also provides ventilation to the building during normal day-to-day operation, which helps maintain a comfortable environment for patients, visitors and staff.
In comfort ventilation mode, the system uses SE Controls compact NV LogiQ controllers to monitor temperature, humidity and carbon dioxide levels within the building, as well as receiving signals from external temperature and wind direction sensors.
The window vents are opened and closed automatically by 41x SE Controls SECO NI 24 40 chain actuators, which are compliance-tested to the relevant EN12101 standards for use with automated smoke control system vents. If a fire should occur, the system automatically switches to smoke control mode, allowing occupants to escape by keeping routes clear of smoke.
As the operation is integrated into the building’s fire system, once a fire signal is received six SE Controls OS2 SHEVTEC controllers take over the ventilation system’s operation, which fully opens ground and second-floor windows automatically, enabling the maximum volume of smoke to be vented. They remain open until the system is reset after the incident.
