Before commissioning
Before commissioning, each fire damper must be
inspected to determine and assess its actual condition.
The inspection measures to be taken are listed in the
Ä Table on page 167 .
Operation
During normal operation the damper blade is open to
enable air passage through the ventilation system.
If the temperature in the duct
(
≥
72 °C /
≥
95 °C in warm air ventilation systems) or
the ambient temperature (
≥
72 °C) rises in the event of
a fire, the thermal release mechanism is triggered. This
action closes the damper blade.
CLOSED fire dampers
Fire dampers which close while the ventilation and
air conditioning system is running must be inspected
before they are opened again in order to ensure their
correct function
