Fire dampers SagiCofim Leakage in hot: the best performance Test 1 Into a vertical aerated concrete masonry wall and into a concrete concealed ceiling: EI 180 (ve ho i ~ o) S Leakage in hot = 0 m3/ h • m2 (vs an admitted max of 360 m3) with a drop pressure of 300 Pa. EI 120 (ve ho i ^ o) S Leakage in cold = 9 m3/ h • m2 (vs an admitted max of di 200 m3) with a drop pressure of 500 Pa. Test 2 Into a vertical lightweight plasterboard wall of 100 mm: EI 120 (ve i ~ o) S Leakage in hot = 0 m3/ h • m2 (vs an admitted max of 360 m3) with a drop pressure of Pa. E 120 (ve i ~ o) S Leakage in cold = 19...

Fire dampers Making safety a priority European Standard Certificated Fire dampers In case of fire in buildings the most dangerous risks for people safety is propagation of smokes. HTE 400 fire dampers are: • Certified according to European Standard UNI EN 1366 - 2 • Classified according to UNI EN 13501-3. Making use of new fire dampers associated with fire detection and smoke extraction systems, these risks can be reduced remarkably. Fire dampers are used in correspondence to fire prevention compartments to guarantee a perfect continuity of the fire resistance characteristics and to avoid the propagation...

Fire dampers European standard and application in Italy: state of the art Certification, Classification and Performing evaluation Standards. In the last five years there were very important memorable dates to understand what’s happened before the publication date of the present document ( 2012 March) about the standard on mechanical smoke, heath and fire control systems. Performing certification is according to UN EN 1363 - 1 and UNI EN 1366 - 2. Classification is according to UNI EN 13501 - 3. Fire damper performing is evaluated with the following standards: In February and March 2007, on Italian...

Fire dampers Building features HTE 400 fire damper is tested according to UNI EN 1366-2, and it is made by an insulating duct between two galvanized sheet iron ducts. Into the insulating duct a blade turn on a horizontal symmetrical rotation axis actuated by a special mechanism. Due to a special silicone seal the damper guarantees a perfect sealing against cold smokes, and the thermo expanded seal guarantees complete heath resistance Performance HTE 400 building features make it perfectly according to European Standard level. Leakage at cold smokes tests are tested at 500 Pa loss pressure with...

Fire dampers SagiCofim Chart. 1 Shape coefficients Pressure drop Diagram A Air passage resistance is one of 1000 the technical features into CE certificate. Energy waste can be controlled choosing correctly air ducts system and fire dampers performances and by a perfect installation into the air system. The damper dimension coefficient(Chart 1) with the 100 frontal speed, as diagram A, establish TFE 40 fire damper pressure loss. Or you can verify which dimensions satisfy a particular pressure loss observing diagram A and in a second time to know the right dimension using the Chart 1 coefficient. 10...

Fire dampers SagiCofim Release and resetting systems Fuse and Manual system Resetting lever allows to move the blade to open position; the blade can be maintained in open position by the little lever which connect it to the release system. Optional microswitches show thermal fuse action and the blade closing, or its open position. Manual system is the simplest and it guarantees fire damper working only in presence of local temperature rise into the duct. It is not possible a local or remote control of the damper working.

Fire dampers Manual system with Electromagnet Motorized system Resetting lever allows to move the blade to open position; the blade can be maintained in open position by power given to linked electromagnet (24V CA/CC-48V CA/ CC 230V CA/CC). The engine connection to electricity network according to furnished voltage (24V CA/CC 230V CA/CC) allows to move the blade to open position. The actuator turn the control damper pin and at the same time, charge the return spring. As the input power is interrupted the tension of return spring replaces the fire damper to safety position. The tension cutting...

Fire dampers Installation details Direct application field HTE 400 fire damper has been studied for installation within certified REI masonry walls, lightweight plasterboard walls or in concealed ceiling. As in the title of UNI EN 1366-2 provision, the direct application field of test results specifies the conditions, different from those in the tests, for which the damper can be installed so to avoid other new tests. The details of installation and the sealing procedure have to be as explained into EffeBi technical guide, and it’s very important to follow all the installation stages and the indications...

Fire dampers CE marking, recognized by all 27 EU Member States, ensures the free movement within the European market of products. CE marking guarantees that a product complies with technical European standard called Harmonised European Standard (EN). These Standards are elaborated to avoid technical barrier for building products commerce; they are the new reference point for national standards and when a manufacturer demonstrates that his product comply with all requirements of Harmonised European Standard, then he can put the CE marking on his goods. Symmetrical fire damper with two ducts in...
