STAIRCASE PRESSURISATION SYSTEMS
A typical staircase pressurisation
system is located within a protected
stairwell to prevent smoke from
contaminating the critical escape
route. If the building is greater than
11m in height, the system should
supply air into the stairwell at every
third level and should ensure via
a twin air inlet arrangement that
no smoke will be drawn back into
the system. Each lobby has an air
release facility.
A staircase pressurisation system
generally consists of a rooftop
fan set and a twin air inlet duct
arrangement together with a series
of smoke damper and grille sets
(the inlet duct size is calculated
specifically to suit the building
requirements). Zone control units
are networked and include fire
officer over-ride switches, pressure
sensors and smoke detectors (or
an interface connection from the
landlord's fire alarm system).
