MOUNTING AND SET-UP

The dampers are installed into square or rectangular (KP-1, KP-2 series) and round (PL-10 series) air ducts of ventilation systems, and the apertures of ventilation shafts, division walls and fire partitions.
The installation of the dampers into ventilation systems must be carried out in consideration of the air flow direction. While installing electrically actuated dampers provide for sufficient space for the actuator inspection.

• When preparing the fire-safety dampers for installation the damper casing must be fitted with wooden spreader bars to prevent deformation, torsional twisting or geometry perturbation of the casing which may result in flap jamming and, eventually, loss of the damper functionality.
• Following the damper installation into the shaft, wall or ceiling filler structure section and upon complete curing (immobilization) of the mortar make sure to remove the wooden spreader bars. The damper must open and close freely without excessive friction.
• To install the dampers into the apertures of wall or ceiling slabs fill up the gaps between the damper casing and the aperture. The gaps are filled with fire-resistant mortar.
• The damper design enables its attachment to air ducts and other ventilation system components by means of flanges as well as its installation into filler structures. Under any installation scenario the mating structure fire-resistance level must be upgraded by using extra fire insulation to at least match that of the filler structure of the respective fire-safety zone.
• According to EN 15650, each fire damper must be installed in accordance with the mounting instructions provided by the manufacturer!

KP-1, KP-2 DAMPER INSTALLATION

• The dampers can be installed in any position into vertical and horizontal channels of fire-protection structures. The damper installation openings must be made in such a way so as to prevent the transfer of loads caused by the fire-protection structures to the damper casing. The adjoining air duct must be suspended in such a way so as to prevent the transfer of air duct load to the damper flange. There must be at least 350 mm of unrestricted clearance for accessing the control elements. Make sure to arrange an inspection hole. While carrying out the installation mind size K. When two or more dampers are installed into the same fire-protection separation structure the distance between the two adjacent dampers must be at least 200 mm.
• The damper must be installed in such a way that the damper flap lies in the fire-protection divider structure plane while closed. If such installation is not possible, the damper casing part between the fire-protection separation structure and the damper flap must be insulated with a suitable material pursuant to the applicable standards.
• The damper control mechanism must be protected against damage and contamination. Avoid damper casing deformation during the embedding. After the installation the flap must not catch against the damper casing while opening or closing.
• Fire-safety dampers can be integrated into a tight wall structure – e.g. made of conventional concrete work of minimum width W = 100 mm or into a plasterboard wall of the necessary fire resistance class or into a tight ceiling structure – e.g. made of conventional concrete of minimum width W = 150 mm.
• The recommended values for construction openings are given below.

PL-10 DAMPER INSTALLATION

• Fire-safety dampers can be installed into solid walls with the minimum width of W = 150 mm, into both round and square apertures, minimum intermediate layer thickness S = 50 mm. The walls can be made of concrete, brick or foam concrete blocks. The intermediate layer can be made of concrete or mortar. While carrying out the installation mind size K. When installing the dampers into thicker walls add an extender section on one of the damper sides.
• The electric actuator can be positioned freely on either side of the fire control sector (space) wall.
• Fire-safety dampers can be installed into solid ceiling panels with the minimum thickness of W = 150 mm, minimum intermediate layer thickness S = 50 mm. The ceiling panels are made of concrete. The intermediate layer can be made of concrete or mortar. While carrying out the installation mind size K.
• When installing the dampers into thicker walls add an extender section on one of the damper sides.
• The electric actuator can be positioned freely above or below the ceiling panel of the fire control sector (space).

Permissible positions for fire-safety damper installation
The damper axle and actuation mechanism can be installed in any position – from horizontal to vertical.

CONNECTION TO POWER MAINS

• The actuators featuring a return spring are designed to control fire-resisting dampers and smoke-extraction dampers installed in ventilation and air-conditioning systems.
• The return spring is cocked upon setting the damper flap to the horizontal position. In case of a power failure, the damper flap is re-set to the protective position by the energy stored in the spring.
• The damper does not require any limit switches and is overload-proof.
• The thermally sensitive breaker Tf1 actuates upon ambient temperature exceeding 72 °C. The renewable thermally sensitive breakers Tf2 and Tf3 actuate upon the air duct temperature exceeding 72 °C. The operation of the renewable thermally sensitive breakers interrupts the electric power supply in such a way that it prevents actuator re-activation without their replacement.
• The button on the thermally sensitive breaker body enables testing the damper functionality.
• The actuator is equipped with two fixed microswitches which signal the end positions.
• Intermediate positions of the damper are shown by the mechanical indicator (needle).
• The BF24-T and BFN24-T actuators are connected via an insulated transformer unit .
• The damper can also be controlled manually and fixed in any position. The unit can be unlocked either manually using a hex wrench (included) or automatically upon power-up.
• The actuator connections (cables and wires) must be durable, insulated and heat-resistant.
• The recommended minimum conductor cross-section is 0.75 mm2. The conductor cross-section selection must account for the maximum permissible wire heating which depends on the wire type, its insulation, length and installation method (i.e. overhead, in cable channels or inside walls).

TECHNICAL MAINTENANCE

• The damper technical maintenance includes routine inspections and functionality checks.
• The damper technical maintenance frequency must comply with the established technical maintenance frequency of the fire safety equipment complex of the facility.
• Recommended inspection steps according to EN 15650:

  5. Check the condition of the blade and seal, perform correction and registration actions (if necessary).
  6. Check that the damper is able to close properly.
  7. Check the functionality of the damper: opening and closing using the control system, physical inspection of the blade behaviour, perform correction and registration actions (if necessary).
  8. Check the functionality of the limit switches in the open and closed position, perform correction and registration actions if necessary.
  9. Check that the damper is operating as intended as part of the control system (if necessary).
  10. Check the standard operating position of the damper.
