1. Product presentation

Fire dampers FDC25/FDC40 are installed in ventilation ducts between fire compartments in order to stop the spread of fire and smoke trough the duct. They have a modular (manual or magnet) or motorized mechanism, entirely outside the wall. Casing is made out of galvanized steel sheet, damper blade is made of special insulating material, and damper blade shaft and push rod are made of stainless steel. Bearings are made of brass, seals of polyurethane and elastomer. The fire damper can be equipped with a simple mechanism with thermal fuse, or with solenoid actuator mechanism or with electric actuator mechanism..

• Tested according to EN 1366-2 up to 500 Pa• Airtightness according to standard EN 1751 class C• Approved for installation in a concrete wall, a concrete slab, plasterboard wall and gypsum

blocks wall• Operating mechanism completely outside the wall• Easy to install• Maintenance free

4. Storage and handling

As a safety element, the fire damper must be stored, handled and installed carefully. Pay attention to: • unload in a dry area • avoid any shocks • do not use the damper as a workbench or scaffolding • do not fit the small dampers in the large one

The damper must be stored in a dry place, and kept out of water and frost. It should not be stacked beyond the original packaging. It must be properly stowed so as to prevent any damage or deformation resulting from an impact or high humidity. It must not be exposed to direct sunlight to prevent premature aging of the thermal fuse. Once the damper is installed, the mechanism should be kept away from any projections (cement, paint, flocking, water, dust) that may harm its operation. The damper must be protected against the risk of heavy condensation. The intumescent joints are essential for the fire resistance of the damper, all mechanical actions on the refractory parts are to be excluded. All precautions shall be taken to ensure that premature aging of the damper does not occur before it is actually installed. The actions of wedging and caulking during the sealing of the dampers must not cause deformations that will alter the good functioning of the damper and in particular the closing of the blade.

5. installation and implementation

5.1 installation

• Mounting is possible with the blade axis in horizontal or in vertical position • The installation must comply with the tests that were performed during certification,

as explained in 8.2• Avoid any obstruction of the moving blade by the connected ducts • The class of air-tightness is maintained in case the installation of the damper is made in

accordance with the technical manual • Operating temperature: 50 °C max • For indoor use only The FDC25/FDC40 fire damper is always tested in standardized support frames (both in a concrete wall and in a flexible wall) in accordance with EN 1366-2: 1999 table 3/4/5. The results obtained are valid for all similar support frames which have a thickness and/or density and/or fire resistance similar or greater than the one of the test.

8. Other mechanism

BELIMO

OperationDamper is delivered in closed position. When electric actuator is connected to the power supply damper will open. When the damper reaches the end position (damper open), the electromotor will stop. Closing fire damper takes place automatically when a power failure occurs. Thermal tripping device that comes with fire damper causes power circuit break at a temperature of 72 °C (inside or outside duct). If checking is needed for proper functioning of fire damper, pushing the switch on the thermal tripping device will close damper. When switch on tripping device is released, the damper will open.

Damper can be opened without connecting to a voltage with enclosed handle turning in the direction of the arrow on electric actuator (clockwise). Damper can be locked in the desired position by fast turning back handle a quarter of a turn (counterclockwise) for Belimo BF, and by puling brake on Belimo BFL and BFN.

To unlock the electromotor, turn handle clockwise for a quarter of a turn for Belimo BF, or release brake for Belimo BFL and BFN. After release, damper will be closed by return spring. When damper is opened manually, electric actuator will not move the damper into closed position after power failure.

SCHISCHEK ExMax

Operation Damper is delivered in closed position. When electricactuator is connected to the power supply damperwill open. When the damper reaches the end position (damper open), in which is it blocked, the electromotorwill stop. Closing fire damper takes place automatically when a power failure occurs. Thermal tripping device that comes with fire damper causes power circuit break at a temperature of 72 °C (inside or outside duct). If checking is needed for proper unctioning of fire damper, pushing the switch on the thermal tripping device will close damper. When switch on tripping device is released, the damper will open.

Damper can be opened without connecting to a voltage with enclosed Allen key, by turning in the direction of the arrow on electric actuator (clockwise). After release of Allen key, damper will go to closed position.
