As per nfpa 101 ,
is it required to install smoke control system for new building,?
NFPA 101 does not require engineered smoke control systems in all health care occupancies. The most common are smoke control systems for atrium and stair-pressurization for enclosed exit stairs in high-rise buildings. However NFPA 101 does address smoke control using a variety of passive and active features of the building. For defending occupants in place, smoke control during is critical. While keeping in mind the patients may have to be relocated.
The code section [19.7.7] referred in your attachment applies only to the maintenance and testing of existing engineered smoke control systems if there was one installed for new construction. Otherwise, this code section does not require a system to be installed.
Thank you mr milton
