Functional test
General
During operation at normal temperatures, the damper
blade is open. A functional test involves closing the
damper blade and opening it again. The exact proce-
dure depends on the type of release mechanism.
WARNING!
Risk of injury from the release mechanism or from a
moving damper blade. Do not touch the release
mechanism or reach into the fire damper while
actuating the release mechanism.
