Understanding Types of Smoke
Control Systems
Two types of smoke control systems exist—dedicated and
nondedicated. The dedicated smoke control system is installed in a
building for the sole purpose of controlling smoke. A nondedicated
smoke control system uses parts of the building’s HVAC system to
control smoke.
In most instances, a building has both nondedicated and dedicated
systems. Nondedicated systems are used throughout the building for
normal areas (offices, manufacturing). Dedicated systems are used for
special areas, such as elevator shafts, stairtowers, and other areas that
need special smoke control techniques.
The operation of the nondedicated smoke control equipment is verified
by the “comfort level” in the areas that are served by the equipment. In
other words, if the HVAC equipment is not functioning properly, the
building’s occupants will be aware of this and the problem will get
fixed.
The operation of the dedicated smoke control equipment is verified by
an automatic self-test that is performed on a weekly basis.
