Functional test FKRS-EU with ExMax or RedMax spring return actua... 5 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 procedure 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. 5.
Functional test FKRS-EU with ExMax or RedMax spring return actua... Opening/closing the fire damper using the crank handle Fig. 7: Functional test (without power supply) DANGER! Danger due to malfunction of the fire damper. If the damper blade has been opened by means of the crank handle (without power supply), it will no longer be triggered by a temperature increase, i.e. in the event of a fire. In other words, the damper blade will not close. To re-establish its function, connect the power supply.
