When the damper is installed on a concrete or masonry wall or ceiling, the size of the installation hole is about 0D + 50 mm. Detailed installation instructions, as well as an installer's installation certificate form, are supplied with each product. Pressure drop and sound data Sound power level Lw, in in each ocatve band is computed bu adding the corresponding correction factor, Kok, to the sound pressure level in the selection chart according to the following equation. Lw = LpA + Kok The corresponding factor Kok is the average of the FDE operating area.

The fire damper can be equipped with a bipolar microswitch, which indicates the closing of the shutoff blade. The microswitch has potential-free contacts (no=normally open and nc=normally closed), which can be used to control other fire dampers equipped with an electric release (e.g., triggering an alarm in the fire suppression system). The maximum operating voltage and current is 400 V, 10 A. Actuators Manual actuator, MA (spring return) Belimo BLF24-T HI, operating voltage AC/DC 24 V (72 °C, contains a microswitch), B1 Belimo BLF230-T HI, operating voltage AC 230 V (72 °C, contains a...

The FDE unit is a circular fire damper of fire resistance class EIS 15, ES 90 and E120, which prevents fire and smoke from spreading in ventilation ducts. The fire damper is equipped with either a motorised actuator or a manual actuation arrangement. Under both options, a fuse reacts to a rise in temperature, causing a spring-return blade to close. If the power in the motorised actuator system is switched off, the blade closes automatically. The FDE can be installed in any direction, and setting is performed from outside the device. The fire damper is made of fireproof materials. Once the...

Connect via safety isolating transformer! Mineral wool Steel frame Fireproof sealing mass Electric actuator wiring diagram Product size + about 5 mm Installation on lightweight plasterboard walls Manual FDE actuator wiring diagram (limit switch, MS) When the fire damper is installed on a lightweight plasterboard wall between fire compartments, a small opening for the fire damper must be left in the plasterboard walls. There are no restrictions on the position of use. K1 To make installation easier, the fire damper comes with an installation flange, which is used to fasten the fire damper...

A released damper can be reset after the fuse temperature has fallen below the release temperature. If the shut-off blade does not lock, the fuse is worn out and must be replaced. Suggested specifications The casing and blades of the fire damper shall be made of galvanised steel. The release spring shall be made of stainless steel. The thermal fuse release temperature shall be as specified, (50, 65, 72, 100, 120, 150 or 200 °C). The fire damper shall have means for opening and triggering the release externally. The fire damper shall include a position indicator. Where indicated, the damper...
