Functional description
Upstream shutters of air transfer units prevent fire and
smoke from spreading in buildings. The thermal release
mechanism closes the upstream shutter of the air
transfer unit when the release temperature of 72°C is
reached. Smoke can, however, spread below this tem-
perature.
The upstream shutter of the air transfer unit consists of
the FKR-EU fire damper with a thermal release mecha-
nism for 72°C and with cover grilles on both sides, but
without a duct smoke detector.
The following applies to Germany:
If fire dampers with a purely mechanical shut-off ele-
ment are to be used as an upstream shutter of an air
transfer unit, the local building regulations must be
observed. Usually the use of such upstream shutters of
air transfer units is restricted to pressure differential sys-
tems.
