3 1. INTRODUCTION Round RK370M fire safety valves with fire resistance class EI 120 (ve ho i o) S are manufactured by FRAPOL Sp. z o.o. in Krakow and are intended for use in the construction industry as elements closing ventilation ducts during the fire within vertical fire barrier (wall or ceiling) to prevent permeation of hot gases and fire smokes via this way to zones not covered by the fire. The fire safety valves feature: EC Certificate of Conformity No CPD-0351/W issued by: Building Research Institute Warszawa, ul. Filtrowa 1 For conformity with harmonised European standard: PN-EN 15650:2010 Ventilation for buildings. Fire dampers They also feature: Hygienic Attestation HK/B/1539/01/2012 issued by: National Institute of Public Health National Institute of Hygiene Warszawa, ul. Chocimska GENERAL CHARACTERISTICS RK370M cut-off fire safety valves are made in the following sizes: Ø100; Ø125; Ø160; Ø200; Ø250 and Ø315 mm. On both sides, the valves are adjusted to muff or nipple connections. The valves are manufactured in variants HO; HE; MR and ER. They can be adjusted for power supply of 24V or 230V (details in version descriptions). Total length of the valve amounts to 370 mm, except for the ER version, for which the length amounts to 270 mm or 370 mm. Valves can be furnished with a thermal trigger adjusted to actuation at the temperatures of 72±5 C or 90±5 C. The valves comprise a round body made of galvanised steel plate, cut-off partition made of PROMATECT boards, ventilation and expansion seals, bearings of the cut-off partition and the drive shaft, drive element and drive transmission elements, thermal trigger, and additional auxiliary elements, such as supports, catches, limiters, bands, etc. 3. VERSIONS Depending on the opening method and method for keeping the valve s partition in the open position, as well as furnishing, there are the following versions of the valves: 3.1. HO version with lever-spring mechanism, opened manually, thermal trigger. The cut-off partition of the valve is kept open by the band, manual lever and release element suspended on the peg of the thermal trigger (mechanical thermal element). Closure of the cut-off valve can occur as a result of: - increase in the temperature of the flowing air to the temperature where the heatresponsive device of the thermal trigger breaks (gets unsoldered (standard 72±5 C). - manual release of the lever from the trigger this allows for periodical closure of the partition to control valve operation. The operation of the thermal trigger (mechanical heatresponsive device) involves air stream flowing round the thermal element (glass ball or soldered metal plates) causes heating of the liquid inside the ball (or solder), which causes breaking of the glass cover (or dissolution of solder), and as a consequence the valve closes when the air flowing through the installation achieves the temperature of ~72 C. The actuation of the heat-responsive device releases the peg of the mechanical thermal element based on it, and the latter, by moving backwards, triggers the element blocking the partition of the valve blocking it in the open position. 3

4 The spring installed at the drive shaft, stretched during valve opening, after actuation of the thermal trigger, closes the valve via the lever system and band, and keeps the partition in the closed position, pressing the manual lever to the resistance angle bar at the drive board. Further air (gas) temperature increase inside the valve (above 140 C) will cause swelling of the expansion seal placed on the internal circuit of the valve body in the surface of closed partition, as well as sealing and blocking the partition in this position HE version with lever-spring mechanism, opened manually. The structure and operation of the valve in this version is identical as in the case of HO version. The difference between the HO and HE variant comprises the fact that HE valve has an additional micro-switch, which via relevant electrical system allows for signalling the position of the valve partition, and makes it possible to use it in control systems (e.g. switching off the fan when the valve is closed) MR version - with lever-spring mechanism, opened manually, solenoid hold-off, under the influence of shortage of power supply for the solenoid the trigger releases the cut-off partition held in the open position. In the open position, the cut-off partition of the valve is sustained by the solenoid powered with 24V DC, connected with electric installation via micro-switch at the electrical thermal element and the adjacent keeper installed on the manual lever. On request of the ordering party, a valve of this type can be furnished with a rectifier transformer powered with 230V AC. Closure of the cut-off valve can occur as a result of: - increase in air temperature to the temperature where heat-responsive device of electric thermal element is actuated and disconnects power supply to the actuator. - disruption of power supply to the actuator from the signal from fire safety control unit. Operation of electrical thermal element is similar as of mechanical thermal element, with the difference that breaking of thermal element (dissolving of solder) at the electrical thermal element causes moving back by the micro-switch keeper and opening of the circuit supplying the solenoid, which means shortage of force holding the solenoid keeper. The spring installed on the drive shaft, via the lever system, causes closure of the partition. Additionally installed limit micro-switch, via relevant electrical system, allows for signalling the position of the valve partition, and makes it possible to use it in control systems ER version Opening and keeping the valve partition in the open position in this version, as well as its closing, is performed by one of electrical actuators of BLF type by Swiss company BELIMO, specially adjusted to operate fire safety valves. The actuators can be powered with 24 V DC and AC voltage or with 230 V AC voltage. Actuator can be installed in parallel or perpendicularly to the axis of the valve. Actuator setting can be performed on request, but it can also be changed during the assembly of the valve by Frapol s technicians or an authorised person. Digital actuators are calibrated after installation in the valve. Replacement or moving the actuator to another valve requires recalibration. Closure of the valve partition can occur automatically as a result of gap in power supply to the actuator caused by: - increase in air temperature to the temperature where heat-responsive device of electric thermal element is actuated and disconnects power supply to the actuator. - disruption of power supply to the actuator from the signal from fire safety control unit. Depending on the actuator type applied, the heat-responsive device is used, the operation of which is identical as in the case 4

5 of MR type fire safety valve, or some actuator types are manufacturer-furnished with their own thermal trigger. Electric actuator kept live all the time maintains the valve in the open position. Upon a gap in power supply, the return spring on the drive shaft, using its accumulated mechanical energy, via the drive system, closes the partition and keeps it closed. In the case of valve closure caused by power shortage, reconnection of power will cause valve opening. If power shortage, however, was caused by actuation of the electrical thermal element, reopening of fire safety valves can only be possible after replacement of the thermal element, on condition no other elements of the valve have been damaged. BELIMO actuators feature installed micro-switches that signal drive shaft rotation by 5 and 85 (position signalling), hence it is not required to install additional micro-switches informing about position of the partition. 4. PRINCIPLES FOR INSTALLATION OF FIRE VALVES 4.1. GENERAL REMARKS Before starting the installation of fire valves, do the following: Check for conformity of the device supplied with the design (type, variant, size and power supply voltage) Check whether there are no visible signs of damage during transport or storage at the site Check for completeness of the device, and its operation in justified cases, and prepare the valve for installation. All valves are supplied in the closed position. Valves in HO and HE versions. In order to open the valve in these versions, the manual lever outside the body must be turned anticlockwise. During valve opening, the spring that serves to close the valve is stretched. After turning the lever to full opening of the valve, hook the lever on manual trigger, wire protruding from the thermal element so as to keep the valve open. After releasing the manual lever from the catch, the stretched spring shifts the partition from open to closed position, in final phase of movement, in the HE version, leading to overload of the micro-switch. Movement of the partition when opening and closing must be smooth, without stops, binds, and excess resistance. In the closed position, valve partition with its ventilation seal must adhere at the entire circumference to the expansion seal, and the manual lever should be rested on the drive board. Valves in MR version Checking the operation of the valves is analogical as in the case of HE version, except for holding and releasing the manual lever, which is done by the solenoid. In order to check these valve versions, connect relevant voltage to the solenoid or transformer via switch allowing for switching the power supply on or off. For MR version, it is necessary to have power supply on so that the cut-off partition is held in the open position. Opening of the valve by turning the manual lever until contact of the solenoid with the keeper and lever release (without power connection) is a sufficient check at this phase to assess valve functioning. Effective holding of the cut-off valve in the open position largely depends on the cleanliness of contacted surfaces of the solenoid and the keeper. Valves in ER version Valve without connected power supply remains in the closed position. By turning the crank at the BELIMO actuator in the direction marked on the actuator, we open the partition. After complete opening, when the crank is released, the spring wound on the actuator shaft should automatically close the partition and keep it in this position. Similarly, movement of the partition when opening and closing must be smooth, without stops, binds, and excess resistance Check for the size and shape of openings prepared in the walls to set the valves acc. to section Check whether after valve installation it will be possible to open them and access them from the maintenance side (valve drive) to allow for possible replacement of elements or periodical check If discrepancies are found, take explanatory measures and achieve conformity with the requirements REQUIREMENTS FOR THE SIZE AND SHAPE OF OPENINGS FOR FIRE VALVE ASSEMBLY DEPENDING ON THE TYPE OF FIRE BARRIER 5

6 Requirements for the size and shape of openings for valve installation in the brick wall. The axis of the opening made must be in the axis of the ventilation duct installed Requirements for the size and shape of openings for valve installation in the wall of cardboard-plaster boards. A=60 mm for valves with insulated metal band. A=120 mm for valves with just the band of PVC. Bearing profile of plaster wall 4.3. PRINCIPLES FOR INSTALLATION OF FIRE VALVES Assembly of the valves must correspond to one of the installation variants acc. to section The partition s rotation axle can be horizontal or vertical Air flow direction via the valve is of no significance for its assembly method Valves in standard version cannot be exposed to weather conditions or chemically aggressive environment Valve installation can occur in the vertical or horizontal fire barrier (ceiling) The applied assembly materials and the suspension method must prevent unintentional change of the valve position against the fire barrier. The valve must be connected to the ventilation installation without any tensions, in a durable and leak-proof manner In the closed position, the cut-off partition must adhere to the expansion seal inside the casing with its seal on the entire circumference On both sides of the valve partition inside the ventilation duct, there must be free space to allow for its opening Electrical installation of the signalisation and powering of the drive elements must be made according to the automation documentation and schematic diagrams for the relevant valve version, according to section 4.5. (to be performed by qualified electrician) After installation of the element in the fire barrier (depending on the version, valve or duct), sealing must be provided between the fire barrier and the element installed, according to the adopted version. After sealing, check for correct operation of the valve and whether the elements of the valve drive have not become dirty. If so, clean them After installation of the fire valve and test operation, perform the commissioning confirmed with acceptance document FIRE VALVE INSTALLATION VARIANTS The valves installed inside the opening in a concrete or brick fire barrier of full brick or of cellular concrete blocks: Valve installation in this variant can occur in fire barriers (walls or ceilings) with thickness G required to provide two-hour separation, namely: - barrier made of concrete mm, - cellular concrete blocks mm, - barrier of full brick mm, In such fire barriers, make an opening shown in section and place there RK370M valve so that it protrudes from the fire barrier on the drive side max. at the distance A = 213 mm (see drawing) (A = 113 mm for ER270). 6 Valve partition axis cement / limecement mortar or promastop MG III valve drive Fire barrier

7 Bilateral sealing of valve and fire barier with Fire-safety mass e.g. PROMASEAL-Mastic Suspended ventilation duct Connect the valves with the suspended ventilation ducts on both sides of the fire barrier The gap between the valve casing and the fire barrier must be carefully filled with cement, lime-cement mix or PROMASTOP MG III fire-protective mortar, or fire safety foam. It is prohibited to force in any pieces of brick or concrete while sealing, as this might lead to deformation of the casing, and thus prevent free rotation of the partition and its closure Valves installed in a light fire barrier made of plaster and cardboard boards: Valve installation before assembly of ventilation ducts: - Perform a relevant opening in the fire barrier, acc. to section Prepare four forms with dimensions Dn+115 mm of cardboard and plaster board with the thickness of 12.5 mm. - Cut openings in the forms corresponding to the outer footing of the valve with the clearance of approx. 5 mm on each side. - Fix two resistance angle bars each opposite to the steel profile of the plaster barrier (on horizontal or vertical profiles). Connect the prepared forms of cardboard and plaster board using special bolts for such boards, and screw the whole to the Plaster boards of wall 2 layers Setting detail: Mineral wool min. 100 kg/m 3 Steel profile of plaster barrier. Valve RK370M Suspended ventilation duct drive Steel band width. 35 mm at circumference mineral wool min 100 kg/m 3 or_ fire-safety foam e.g. PROMAFOAM resistance angle bars in the fire barrier. - Place the valve centrically in the prepared opening of the board affixed so that it protrudes from the wall on the drive side to the distance A and support for foam setting period. - Carefully fill the (5 mm) gap between the valve and the forms of cardboard and plaster board using a fire-protective foam and leave until the foam settles. - Cut off excess foam and fill the remaining gaps between outer cardboard and plaster boards and the forms inserted with mineral wool or also with fire-protective foam. - Install the outer panels of the fire barrier, and seal the valve and the fire barrier on both sides with fire-protective mass. Plaster screw Resistance angle bar Fire-safety foam e.g. PROMAFOAM Bilateral sealing of valve and wall with firesafetymass e.g. PROMASEAL-Maestic Valve installation with simultaneous assembly of ventilation ducts (two variants). - Perform a relevant opening in the fire barrier, acc. to section Assembly the valve to the suspended ventilation installation. It is enough to connect the valve with the installation on one side. The valve installed acc. to variant I must feature insulated steel clamping band at the site of body perforation (on request, the valve supplied can have the appropriate band). The valve installed must be placed centrically in the prepared opening, and should protrude from the barrier on the drive side to the distance of A mm. - After appropriate setting of the valve in the fire barrier, carefully fill the gap between the valve and the steel profiles of the barrier with mineral wool with thickness of at least 100 kg/m 3. 7

8 Variant II installation Angle bar fixing ring Bilateral sealing of valve and barier with fire-safety mass, e.g. PROMASEAL- Maestic Fire-safety valve e.g. PROMAFOAM Plaster boards of wall 2 layers Mineral wool min. 100kg/m 3 Steel profile of plaster barrier Valve RK370M Suspended ventilation duct drive Steel ring with width 35mm at circumference Mineral wool min. 100kg/m 3 or fire-safety foam e.g. PROMAFOAM - Install the outer panels of the fire barrier, and seal the valve and the fire barrier on both sides with fireprotective mass. The valve installed acc. to variant II does not feature the steel band. During assembly of the valve acc. to this variant to steel profiles of the cardboard and plaster barrier, fix the ring supplied on request. Carefully fill the gap between the valve and the ring with fire-protective foam. Other requirements for valve installation in this variant are the same as requirements for variant I Valve installed remote from the fire barrier: The flap can be remote from the fire barrier if dimension "A" for installation in the brick, concrete or light fire barrier is greater than the values stated in the chart in section Distance from the fire barrier is marked as length X of ventilation duct protruding from the wall constituting the fire barrier Assemble the ventilation installation passing through the previously prepared opening in the fire barrier, and connect it to the fire valve, ensuring the designed shift of the valve against the fire barrier, and suspend the installation The gap between the installation and the opening in the fire barrier must be insulated with mineral wool or fire-protective foam The part of the duct protruding from the fire barrier, together with a part of the valve to dimension A must be insulated in the class corresponding to the class of the fire barrier. The drawing below presents examples of insulation using Promatect L 500 boards For size X up to 500 mm, do not use suspensions. For size X up to 1000 mm, use just the suspension at the valve. For X greater than 1000 mm, use both suspensions. For X greater than the length of the board applied, use additional suspensions on board connections. 8

PRINCIPLES FOR FIRE VALVES MAINTENANCE CAUTION: Before performing activities related to electrical connections or replacement of elements in the valves powered with voltage higher than safe, disconnect power supply Replacement of mechanical trigger or heat-responsive element. Valves RK370M/HO and HE Mechanical glass thermal element for valves type RK370M Fig. to section 5.1. Mechanical soldered thermal element for valves type RK370M After unscrewing two M5 screws (item 9 Fig. to section 5.1.) (optionally nut M6), remove the entire mechanical thermal element from the valve, item 1, together with plate, item 2. In order to replace the thermal element (item 3), unscrew the nut (item 4), press the spring (item 7) with the element, and after the element item 1 is bent to the side, remove the glass element (item 3) from the steel clip (item 6), or remove the protection (item 10) and remove the soldered element from the shank (item 11). After placing the glass element in the socket in the brass element (item 5), so that the elongated part of the insert is inside the element, or after placement of soldered element on the shank, assemble the thermal element in reverse order, not forgetting to place a sealing cushion (item 8) under the thermal element plate. The glass element must be set precisely in the socket and opening of the elements (item 6). The shank of the thermal element (item 11) must block the protrusion of the wired catch of the lever from the thermal element Replacement of electrical trigger or heat-responsive element.

13 Disconnect the trigger from electric installation and disconnect connections of the trigger at the valve. After unscrewing two M5 screws (item 4 Fig. to section 5.3.) (optionally nut M6), remove the entire electrical thermal element from the valve with the plate (item 1), as presented in the drawing below. In order to replace the thermal element (item 2), unscrew the brass cylinder or nut (item 3), place new thermal element in the opening or onto the shank (as presented in the drawing), and again screw on the cylinder on the micro-switch shank (item 5). Assemble the whole to the valve in the reverse order, not forgetting to place the sealing cushion (item 6). Connect the trigger to the electric installation and open the valve Replacement of the spring. Valves RK370M HO; HE; MR. Before replacing the spring, unscrew the screw (Fig. to section 5.4., item 3) fixing the manual lever on the drive shaft, set the valve partition in the closed position so that the spring tension is minimum (lever item 1 resting on the limiter, item 4), and next remove lever (item 1) and damaged spring (item 2). Place the spring on the middle opening in the manual lever and place the whole on drive shaft, item 5. During placement on drive shaft, manual lever must be set vertically, namely it should rest on the limiter on the drive board. Set the manual lever in the appropriate distance from the drive board and screw the screw fixing the lever on the drive shaft. Hook the spring on one of the catches (item 6) on the drive board, and assess the strength with which the partition is closed. If necessary, change the spring hooking on the drive board or manual lever, and again assess correct closing of the valve. Repeat these activities until your assessment is positive. Correct valve closure occurs where valve partition freely closes, and the manual lever meets resistance on the drive board without excess noise. After replacement of the manual lever, depending on valve version, reassemble the previously removed elements, and check for their correct operation. Fig. to section Replacement of the micro-switch. Valves RK370M HE; MR. HE version MR version Switch off power supply for micro-switch, item 1. Unscrew two screws (item 2) fixing the micro-switch to the support, remove the damaged micro-switch, loosen the conductor clamp and remove its sheathing. Disconnect conductors consecutively from the micro-switch and connect them in the same way to the new micro-switch. Next, place the sheathing and fix the micro-switch to the support. Set the micro-switch switching point by appropriate bending of the tongue, item 3. The micro-switch should switch the contactors when the manual lever exerts pressure on the tongue and when the pressure is 13

14 removed. Connect power supply of the micro-switch and check for correct operation by observing signalling of cut-off partition s position Replacement of valve actuator. Valves RK370M ER. Switch off power supply and disconnect connections of the actuator, item 1. In the case of actuators with their own trigger, also unscrew the trigger. Unscrew M6x70 screws, item 2, fixing the actuator, and remove the actuator from the drive shaft. In the same position, place the new proper actuator at the appropriate side, to preserve the direction of rotation when opening (anti-clockwise). The direction of rotation is marked on the actuator. Screw the actuator with the screws and perform electrical connections according to the diagrams. In the case of BLF actuator with its own trigger, screw the trigger paying attention to the seal under the trigger. Valves furnished with digital actuators require calibration of the actuator after replacement. The activity can be performed by Frapol s technicians or a qualified person. After power supply is on, test valve operation. 6. PERIODICAL MAINTENANCE The need for and the required frequency of maintenance results from analogical requirements of the installation including RK370M valves. If no specific requirements have been defined for periodical maintenance of the installation, or if the periods between particular checks are longer than six months, check the RK370M valves at least once every six months. This is the responsibility of the Facility Owner. Periodical maintenance of RK370M valves comprises the assessment of their physical condition, and correct operation using the Inspection Document at the end of this Documentation. It is also recommended to assess the condition of the device using the Inspection Document after the end of assembly works and launch of the installation including the RK370M valves HO and HE versions release manual lever (item 1 Fig. Position A to section 6.1) from the catch (item 2 Fig. to section 6.1) keeping the valve open. After releasing the lever, it moves freely from position A to position B (Fig. to section 6.1), closing the valve partition. Next, manually open the valve, and hook the manual lever (item 1) at the element (item 2). For valves in HE version, during the test, observe correct signalling of cut-off partition's position. If irregularities are found, set the micro-switch actuation point (item 3). Position B 6.2. MR version disconnect power supply to the solenoid. The partition should move to the closed position. Then disconnect the solenoid s power supply. Manually turn the manual lever, leading to contact of the keeper and the solenoid. After the partition achieves open position, the manual lever will be blocked by resistance of the keeper against solenoid coil, and valve partition will remain open, kept by the solenoid. During the test, observe correct signalling of cut-off partition's position. In the event of problems with sustaining the partition, check for cleanliness of keeper and solenoid surface ER version disconnect power supply to the actuator. The valve must close (steel arrow on the actuator shaft must be within the field between 0 and 5 of the scale. Turn the power supply of the actuator again. The valve must open (steel arrow on the actuator shaft must be within the field between 85 and 90 of the scale. During the test, observe correct signalling of cut-off partition's position, and its indications shall be decisive. Operation of the air-handling installation with dysfunctional fire valves bears the high risk of their non-performance in the event of a fire, and makes the installation user liable. 14
