Self-actuating backow protector EKO-BSV
is installed in the supply air duct in a FT or
FTX system to prevent the spread of smoke.
The exhaust air system must be dimensio-
ned to be able to evacuate smoke. Both the
supply air and the exhaust air fan must be
in operation throughout the entire re. The
protector closes quickly in the event of a
re that generates an overpressure in the
re cell. It is fully self-actuating and does
not need to be connected to a monitoring
system. Self-actuating backow protec-
tor EKO-BSV is designed so that it can
withstand high temperatures, which means
that it can also be placed inside the re cell
itself. Mounting can be done horizontally or
vertically in a re cell, in a shaft or in a cor-
ridor in such a way that it can be inspected
and cleaned.
The re properties are tested according to
the same test standard as for CE marked
Fire Damper. Fire properties corresponding
to E90 applies provided that EKO-BSV is
mounted in a duct outside the re-exposed
re cell, applies to both wall and oor.
When EKO-BSV is placed outside the ser-
ved re cell it does not need to be depres-
surized.
Ventilation ducts and components are sus-
pended, installed and insulated in accordan-
ce with current requirements in BBR. When
insulating, the inspection requirement of the
product must be taken into account.
Mounting in ventilation duct
EKO-BSV must be mounted in the supply
air duct so that the arrow on the label points
in the same direction as the air ow (supply
air direction).
