FDR-3G…OF

Technical Parameters

Durability test

50 cycles/manually operated activation mechanism – with no change of the required properties
10000 + 100 + 100 cycles/actuator operated activation mechanism – with no change of the required properties

Fire testing pressure

Underpressure up to 300 Pa

Safety position

Closed. (In fire scenario the damper closes via spring in actuator or spring in manual mechanism)

Airflow direction

Both directions

Allowed air velocity

Damper can still operate at max. 12 m/s. Air without any mechanical or chemical contamination

Side with fire protection

Depending on installation classification: From both sides (i <-> o)

Repeated opening

Suitable for daily check procedure. It is not possible to operate the device after reaching Activation temperature.

Activation Temperature

Manually operated: 74 °C as standard by means of a spring after the melting of the thermofuse and/or after smoke
sensor detection.
Actuator operated: 72 °C as standard by means of the spring after current interruption in the electro-thermal fuse and/
or after smoke sensor detection.

Operational temperature

Minimum: 0 °C
Maximum: 60 °C for 74 °C and 72 °C thermofuse

Environment suitability

Protected against weather disruptions, with temperature above 0 °C, up to 95% Rha, (3K5 according to EN 60721-3-3)

Open/Closed indication

Manually operated microswitches - Activation types H2-OF up to H6-2-OF
Actuator operated built-in microswitches - Activation types B230T-OF/G230T-OF up to BSD24T-OF/GSD24T-OF

Closing/Opening time

Manually operated < 10 s, actuator operated < 20 s

Inspection possibility

By opening of the inspection lid. For smaller than DN160 after removing of the activation mechanism, or a inspection
opening must be added to the connecting duct. Smoke senzor can be tested with test button or through damper grille
with smoke spray tester.

Maintenance

Not required. Dry cleaning if demanded by law in the country in which the dampers are installed.

Revisions

Determined by law in the country in which the fire dampers are installed but at least every 12 months.

Allowed pressure

1200 Pa
