SMIA-1 1

Fan unit

SMOKE MASTER SMIA is an all-inclusive total solution for stairwell pres-
surisation and smoke exhaust. The system has been designed and the com-
ponents have been constructed to the pressurisation standard EN 12101-6,
and the smoke extract fans conform to EN 12101-3. SMIA is CE-marked
according to EN 12101-3. The system has been tested by VTT Technical
Research Centre of Finland, and it has also been subjected to full-scale fire
tests, performed in Myllypuro, Helsinki, in a block of flats. SMIA has been 2

designed for use in residential buildings up to eight storeys high.
Control unit
The SMIA fan unit is, due to its compact external dimensions, suitable for
use in new build as well as many refurbishment projects. For ease of design,
it is only available in one size with constant air volumes that works for stair-
wells of many different heights.

An SMIA total solution comprises integrated smoke hatches, a fan unit, a
SMIZ-3 3
control panel, and a control unit. The apartment air release path solutions
with the necessary spindle motors, smoke detectors and control units are
