4 FIRE DAMPER EI90 - GENERAL INFORMATION Example Description: Multiblade fire damper ceritified with compliance of EN The new multiblade fire damper BSK-J/EI90 is tested acc. to EN The damper classification is EI 90 (ve - ho i o) S. The housing and the louver blades are made of fire resistant special-insulated fabric with silicate basis. The distance between strengthened blades inside the housing is 150 mm. Seal tightness per the room temperature (20 C) is achieved with special rubber section on touched edges of the damper. In the hot conditions the seal tightness of the blades is reached by special foaming material installed around the edges of the damper. The axis of the blades are equipped by heat-resistant bearings to ensure the function even in the fire. The connecting flange and the sheet metal parts are made of galvanized steel. The movement of the blades is synchronized. The actuator is placed directly on the axis, the actuator itself is extra thermally insulated. The mounting depth of the damper is 200 mm. Connector on the duct system is manufactured with a 30 mm diameter 4 corners hole flange. The seal tightness per the room temperature (20 C) is secured by the suitable silicone seals. The sealing element is in closed position formed and shaped by meshing of blades. In case of fire, heat expanding seal placed in-between the blades closes the fire damper hermetically. In case of fire the fire damper is automatically closed by the force of actuator. Thermoelectric release mechanism is connected to an actuator by wire. Fire damper can be equipped with following actuators: ACTUATOR BELIMO: BLF 24-T (-ST) BF 24-T (-ST) BLF 230-T BF 230-T ACTUATOR GRUNER: 340TA TA TA TA TA TA-230 Activation temperatures of the multiblade fire damper with a actuator are 72 C and 95 C. By default, the fire dampers with 72 C are delivered. The other temperatures must be specified by order. The actuator guarantees the safety position. By default, the motor is placed on the right side, but it is possible at the request of the customer to be installed on the left side. The blade actuator consists of form-fitting linkage that is with all blades (interlinkingly) connected. The damper actuator is placed in the housing completely outside of the air flow, and in that way meets the requirements of hygienic favorable mounting parts with smooth inner surface, such as for ventilation systems in hospitals. The movement of the blades takes place completely in the housing. In case of fire, the side seals are allowing unobstructed expansion of the dampers. In case of larger dimensions >1050 mm, the fire damper is delivered in more parts. Multiblade fire dampers are tested with a variety of BUS control systems. For the details please check appropriate data-sheet. Keep in mind the following points when planning the ventilation system: In the area of the mechanism, minimum 150 mm space must be available for the moving of the damper axis. Installation: In accordance to table 3 the damper should be used only in following installations. The wall opening should be designed with the following dimensions: B1 = B mm, H1 = H+180 mm (considering the actuator box, see fig. 1). The given dimensions are minimal, by installation inside soft seal the guidelines of the soft seal manufacturer (e.g. HILTI) should be kept. Pay attention to horizontality and rectangularity during installation strictly. Smoothrunning shall be checked after the installation. The activation device as trigger element of the damper and the actuator must have free access. The installation must be done in accordance to installation requirements in all cases! In order to ensure the flawless function of the damper, the following points must be regarded absolutely: a) Maximum airflow velocity 15 m/s Maximum pressure difference 1200 Pa b) The dampers are in the air line installed by the way that they can place themselves in "open" position automatically when the fan is switched off or when the louver damper which is between the fan and the damper is switched off. c) The equal and steady air distribution must be ensured over the cross section of the damper. Dampers are designed for macroclimatic areas with mild climate environment according to EN The damper is designed for air without firm, fibrous, sticky or aggressive additives. 4 4

The damper in the fire protective isolating structure must be mounted in accordance to fig. 21. If this solution is not possible, the ventilation duct must be protected between the fire protective isolating structure and the damper blade in accordance to the certified installation type (see table 3- Installation type overview) and for the exact details for the additional insulation taken from the actual installation diagram and fig. 22. It is important to protect the actuator with a cover against damage and contamination, as long as the wall construction and plastering have not yet been carried out. The damper housing must not be deformed during the wall construction. After the damper installation, the damper blade must not ream against the housing during opening or closing. The distance between the fire damper and the supporting structure (wall, ceiling) must be minimally 75 mm. If two or more fire dampers should be installed in one sector, then the distance between the juxtaposed dampers must be at least 200 mm. Multiblade fire dampers - general installation directions:!!attention!! There is a risk of injury upon edges and sheet metal parts. During transport and installation, always wear protective gloves. The damper that have actuator with spring return, the thermoelectric actuation device that is connected with the actuator by wire, must be installed on the damper. It should be noted that the part of the activation device that protrudes into duct does not interfere with the free movement (the swivel range) of the damper blades. If the damper is with an add-on piece ordered, then the activation device is in the add-on piece installed. The wiring (connection of the actuator) must be produced by an authorized electrician, according to the current standards instructions. Installation position: The damper - BSK-J/EI90 is suitable for the installation in vertical or horizontal position with random blade position. The ensuing ventilation duct must be mounted or supported so that there is not any kind of load transmission from the ducting onto the damper flange. The fire damper has to be installed in a completely tensionless and right angled state. Sufficient room must be provided for maintenance and cleaning on the damper. An access opening must be provided for cleaning and inspection purposes of the damper. In order to ensure the necessary clearance to the controlling device it is recommended that the other objects have minimum 350 mm distance from the controlling parts of the damper. Fig. 2: The distance between the multiblade fire damper and the structures required by EN normative Installation with soft seal: The soft seal must have the dimensions of W x H =1650 x 2050 mm or W x H = 2050 x 1650 mm. The maximum edge distance must not exceed 400 mm! If the size, in accordance to ETA / ETA tested, of blank seal is not exceeded, there are no specifications for the maximum edge distance.

7 MULTIBLADE FIRE DAMPER BSK-J/EI90 - DESIGN AND INSTALLATION The lightweight walls must be prepared by the way that they do not sway the function of the soft seal over the fire resistance period. Lightweight walls must not affect the function of the isolation over the fire resistance period, even in case of possible deformation in the event of fire. (e.g. damage / displacement of the isolation relating to the fire damper/ smoke control damper due to deflection of the wall in the event of fire. When installing more fire dampers, the following points must be considered: The given measurements are based on the installation with the HILTI products. If other brands of soft seals are used, it has to have equivalent material properties and installation conditions must be satisfied! If the size of the soft seal is bigger than the size tested in accordance to ETA / ETA, then the maximum edge distance must not exceed 400 mm. Also, in a seal could be combined the dampers with horizontal and vertical axis. The dampers can be installed outside of the wall, or ceiling structure. The ventilation duct and a part of the damper, between the wall structure and the damper blade must be protected with fire insulation. The allowed types of installation are given in the table 3 and in the corresponding illustrations of the instructions for the additional insulation. By the installation outside of the wall structure or inside the opening, damper must not hang on by its own weight. See fig. 24 and fig. 25. The installation of the damper must be provided according to installation conditions. The fastening, in the event of fire, endures the whole fire resistance period (90 min) and the displacement of the damper is excluded. The dampers must be installed without deformations or damages. The right-angled installation must by secured. Free movement shall be checked after the installation. In any case it should be ensured, that the fire resistance of the whole structure (wall / ceiling / fire damper) is not in any way by installing. Mounting, maintenance, control and inspections of the operating capability must be done by an expert in accordance to directions as well as installation requirements. For the reliable operation of the dampers is important to note, that it does not come to obstruction of the closing mechanism and the sealing surface of the damper blades through dust, fibrous or sticky materials and solvent. Control of the damper actuator without power supply: It is possible to manually adjust the damper blade in random position using the special tool (actuator's accessory). By turning the tool in the arrow direction, the damper blade is moving to the opened position. The damper blade stays in random position by shortly turning the tool (½ turn) in the opposite direction of the arrow. Resetting is performed either manually by turning the tool in the arrow direction or by adding the supply voltage. Activation and control of the function: After the installation, the movement of the damper blades must be checked for the smooth-running. If, for any reason, the damper function cannot be ensured, then this must be explicitly noted. The operator must ensure that the damper will be brought into the state, in which it can again fulfill its function, and during this time, he must ensure fire safety in another adequate manner. Minimal dimensions of the openings: The exact dimensions must be set and agreed with the seal manufacturer, the company that undertakes the first concrete works usually. The minimal dimensions are to be found in the fig. 1. They are placed on pressed mortar procedure. Flange: The flange of the square dampers have in the corners the elongated holes (Fig. 3). In this context, for the installation of the dampers shall generally be recommended the usage of expansion joints as movement compensators, aimed to avoid twisting of the housing, and occurring expansion of the line and out of it resulting energies the event of fire. The remaining gap between the dampers must be sealed correspondingly to the chosen type of installation. Fig. 3 Flange BSK-J/EI90 7 7

11 MULTIBLADE FIRE DAMPER BSK-J/EI90 - INSTALLATION WITH SOFT SEAL IN SINGLE-SIDED COVERED THIN SHAFT WALL Installation with soft seal in light, single-sided covered thin shaft walls Apart from the proper forming of the opening embrasure, the wall deformations under fire load must be regarded for the fire dampers, which are, for the installation with soft seal in accordance to EN and national proposal for the soft seal checkup in accordance to EN , classified, and which should be installed in single-sided covered lightweighted thin shaft walls. In order to achieve no reduction through these wall deformations of the whole- fire resistance of the wall-components-soft seal- combination, the installation in such wall systems requires special methods, that are hereinafter explained. They apply on the fire dampers with test validation in two-sided covered lightweight walls as well as on the single-sided covered lightweight walls, by deploying a soft seal system for the closure of the gap. Since the single-sided paneled thin shaft walls are not the standard support structure and in accordance to EN , the solution that is without any additional test certificate, can be applied, as required by practice, on the basis of orienting fire tests, whereby the following specifications for clear shaft widths "B" apply to maximal 4,0 m and a certificate for the soft seal as blank seal exists in corresponding size and construction. Should the opening size in installation section exceed the allowed size of the blank seal, a structural separation (e.g. minimum 40 mm fire protection panel / silicate) must be provided. A solid wall (e.g. aerated concrete) can replace the singe-sided paneled thin shaft wall, whereby a standard situation is accomplished without additionally required methods. Splitting a lighter, single-sided paneled thin shaft walls in two areas The installation of the fire dampers and smoke control damper in light, single-sided paneled thin shaft walls with soft seal jointing of the remaining areas of the opening requires the separation of the installed (fire dampers / smoke control dampers, also pipes, ducts and cable) from the wall structure itself, and creation of the separated areas for the wall mounting and the installations.

The damper must not hang on its own weight and the weight must always be retained and avoided somehow see fig. 24. In principle is differentiated between two types of fastenings: - Installation with flexible compensators - Installation without the flexible compensators The suspensions, that are longer than 1,5 m, are fire protective coated. For the ceiling installations fastening, the suitable steel dowels or equivalent type of fasteners must be used - see fig. 23. The 'throughhole-technology' (without dowel) is possible also. In this case, the fastening of the threaded rods takes place with nuts and pulleys. Tab. 4. Allowed load F [N] for the fastenings - steel drawbars out of threaded rods, for the fire resistance period 90 min. In correlation to particular choice (with or without the flexible compensators), the quantity and the type of the hangers or suspensions must be appropriately chosen. By the assessed fastenings-structures, the manufacturer's guidelines (e.g. HILTI) must be satisfied. Hanging of a fire damper inside wall construction: The fire dampers can be hanged by use of threaded rods and mounting bracket. The hangers takes place onto the solid ceilings with sufficiently dimensioned threaded rods. The dimensioning of the rods depends on the damper weight. The connected ventilation ducts must be suspended, there should not be any force transferred to the damper.

23 MULTIBLADE FIRE DAMPER BSK-J/EI90 HANGERS AND FASTENINGS FOR OUTSIDE OF WALL CONSTRUCTION Hanging of a fire damper outside of wall construction: The ventilation ducts between the wall opening and the fire damper, and the fire dampers in general, can be suspended by use of threaded rods and mounting brackets. Threaded rods must be dimensioned in correlation to the sizes of fire dampers and ventilation ducts. The hangers should be placed max. 50 mm away from the next duct connection. The maximal distance between two hangers is 1500 mm. The connected ventilation ducts must be suspended, there should be no force acting on the damper. The suspensions, (threaded rods) that are longer than 1,5m, are fire protective coated. If the hanger is situated inside the insulation material, the distance between the ventilation duct and threaded rod must not exceed 30 mm. The insulation under the mounting bracket must be minimally 30 mm thick. If the hanger is situated outside of the insulation, then the maximum distance between the threaded rod and the outer edge of the insulation is 40 mm. For the ceiling installations fastening, the suitable steel dowels or equivalent type of fastening must be used - see fig. 23. Each one layer of insulation should be fastened onto the ventilation duct properly by the using the welding mandrels with cones. The distance between the mandrels and flanges /duct edges/ depends on the material used, and must be taken from the documentation of particular manufacturer. In case of this type of installation, the damper must not hang on its own weight. (See fig. 24.)

25 MULTIBLADE FIRE DAMPER BSK-J/EI90 - GENERAL INFORMATION Possible applications: Damper BSK-J/EI90 is suitable for the normal indoor air environment. Every variation of the air requirements must be defined and agreed with the manufacturer before deployment.!!attention!! Every one piece of damper must be checked for its functionality at least once a year. Control record is requested. Material and surface: The damper housing and the damper blades are made of mineral fiber asbestos-free fire boards. The connection material is electrogalvanized. Dimensional control: The dimensions are controlled by typical measuring instruments according to the used standard for free sizes in the ventilation technology. In-process inspection of the parts and main dimensions according to the drawing documentation will be conducted. Factory production check: After the production, a 100% function check of damper function and shut-off device incl. all electrical elements prior to delivery is be provided and recorded. Delivery: Dampers are transported in a covered vehicles, without direct weather influence. It must not come to rough shaking during transportation and the areal temperature must not exceed +40 C. In case of tempering during transportation, the dampers must be protected from mechanical damages. The fire dampers can be packed on pallets at client's request. During the transport the damper blade is in "OFF" position. The goods handover from carrier to client counts as purchase, unless another type of purchase is stated in the order. The dampers must be stored in covered objects, in the environment without aggressive vapors, gases and dust. In this objects the temperature in range from -5 to +40 C and the relative humidity of max.80% must be kept. In case of tempering during storage period, the dampers must be protected from mechanical damages. Installation - mounting: The mounting, maintenance and control of the operating capability must be done by an expert in accordance to directions and installation requirements. It must be ensured that the precautionary measures for the electrical bonding is carried out in accordance to current installation regulations before damper installation. For the reliable operation of damper is important to note that it does not come to obstruction of the closing mechanism and the sealing surface of the damper blades through dust, fibrous or sticky materials and solvents. Control of the damper actuator without power supply: It is possible to manually adjust the damper blade in every position using the special tool (actuator's accessory). By turning the tool in the arrow direction, the damper blade is moving in the opened position. The damper blade stays in random position by shortly turning the tool (½ wrench turn) in the opposite direction of the arrow. Resetting is performed either manually by turning the tool in the arrow direction or by adding the supply voltage. Commission and control of function: After the installation, the movement of the damper blades must be checked for the smooth-running. If, for any reason, the damper function cannot be ensured, then this must be explicitly noted. The operator must ensure that the damper will be brought into the state, in which it can again fulfill its function, and during this time, he must ensure fire safety in another adequate manner. Checking of the safety function by the motorized fire damper: a) Through disruption and renewed supply line of the supply voltage b) Directly by the installed damper by pushing the button on the BAE72-S thermoelectric release device (simulates the triggered fuse) The annual control of the fire damper occurs in accordance to EN Installation of the fire dampers: The installation of the fire dampers must be performed in accordance to installation requirements and requirement set by national regulations. The right-angled and volt-free installation must always be taken care of. Smooth-running should be checked after the installation. Motorized fire dampers with actuators The checkup takes place on this dampers, at least once a year by disconnecting the actuator from power supply, which closes itself by means of spring force of the closing element and at the same time raises the appropriate holding torque towards impermeability. Thereby also the damper blade alone, the state of the seals, and the open and close position from the inner side of duct must be checked, the signals from electric end switches or other outer position pointers are not enough. Through power disconnection is the closing spring in actuator checked. Should this spring be defected, no closing process shall occur
