MECHANICAL SMOKE VENTILATION SYSTEMS (MSVS)
A typical MSVS system is located
within a protected lobby and is
attached to a rising smoke shaft or
fire-rated ductwork system with a
fan set at the shaft's head.
Systems often allow extended
travel distances within the lobby
and generally consist of a rooftop
fan set and a series of smoke
dampers and grille sets that provide
a free area of 0.6m
2
(the smoke
shaft/ducting itself also having a
footprint of 0.6m
2
). Zone control
units are networked and include
fire officer over-ride switches and
smoke detectors (or an interface
connection from the landlord's fire
alarm system).
In some cases, pressure sensing is
also utilised to reduce fans speed
during means of escape mode
and to allow occupants to escape
without the exit doors being difficult
to open.
Vent-Guard mechanical smoke ventilation systems are designed/installed in accordance
with the relevant sections of the SCA guide, Approved Document B, BS7346-8, BS9991,
BS9999, EN12101-2, EN12101-3, EN12101-8, EN12101-10, ISO21927-9.
