Commissioning
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
table on
Ä
on page 59.
Operation
During normal operation the damper blade is open to
enable air passage through the ventilation system.
If the temperature in the duct or the ambient tempera-
ture rises in the event of a fire (≥ 72°/≥ 95°), the thermal
release mechanism is triggered and 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
