1 Instructions for Installation, Operation and aintenance 10/2016 Installation Fire damper ETPR must be installed according to this installation manual, see pages 2-5. Operation and function testing According to CE marking, a fire damper must always be equipped with a tripping mechanism based on temperature. Fire dampers can be delivered equipped with either a fuse mechanism or an actuator. ETPR motorized fire dampers may additionally be linked to a smoke detection based tripping mechanism. A tripping system based on smoke detection is easy to install using FläktWoods FICO control and monitoring system. The FICO system can also be used for automatic function tests of fire dampers. The function testing for the motorized damper can be performed by cutting off the power supply by using the switch of the thermal trip connected to the motor. The spring will then close the damper. The function testing can also be done by means of the control and monitoring system FICO, either manually or automatically. The recommended automatic function testing interval for the motorized damper is 48 hours. The operation of the fuse mechanism is tested by pushing the red test button the spring will close the blade. Beware of the reset handle as it will rotate rapidly during test operation. To reset the mechanism, turn the handle until the mechanism clicks. aintenance The function testing interval is always determined separately for each building, but testing must be carried out at least twice a year according to product standard EN 15650:2010 (see example of check list beside). WARNING! Never put your hands inside the damper while it is closing. Clean the fire damper by means of a vacuum cleaner. Avoid chemical cleaning agents. Spare parts Actuator: see type specification on the actuator. Fuse part ETFF Fuse part replacement, see page 7. aintenance Check List: Fire damper reference Date of inspection Check actuator wiring for damage (where applicable) Check end-switch wiring for damage (where applicable) Check fire damper cleanliness and clean where necessary Check the condition of blades and seals, rectify and report where necessary Confirm the safety closure operation of the fire damper according to the manufacturer s instructions Confirm operation of damper to OPEN and CLOSE by use of the control system and physical observation of the fire damper, rectify and report where necessary Confirm operation of OPEN and CLOSED end-switches, rectify and report where necessary Confirm that the fire damper fullfills its function as a part of the control system (where applicable) Confirm that the fire damper is left in its normal working position NOTE! A fire damper is usually part of a system. As this is the case, the whole system should be checked as governed by the operation and maintenance requirements for the system.

3 Installation of fire damper into rigid building elements (walls and intermediate floors) with fire classification EI 60 and into floors with fire classification EI 90 (Fig. 1 and Fig. 4) 1. Installation opening in the rigid wall or intermediate floor must comply with the dimensions given in the table below. Size ØD (mm) Installation opening Ø (mm) The fire damper blade must be closed during installation. 3. Place the circular duct centrally in the opening. 4. Place the fire damper in the duct so, that the damper flange rests against the building element. Use screws of sufficient length (e.g. 6 x 40 mm), which are suited for rigid construction, to fasten the damper to the building element through the bendable brackets on the flange. The damper must be fastened at 4 brackets at the minimum. The blade shaft can be placed in any position. 5. Completely fill the gap between the duct and the building element using incombustible, rock based, fine-grained gypsum or concrete cast. Protect the damper whilst infilling. 6. Check the functioning of the fire damper and proper movement of the blade. Clean the damper, if necessary. Place plastic covers on the openings and keep them covered, until ducts are connected to the damper. 7. To reset the fuse mechanism: Turn the handle towards the OPEN position until the mechanism clicks and the blade locks into position. 8. anual function testing of the motorized fire damper can be performed with the tool delivered with the actuator. When connected to a power supply, function testing is done by using the switch of the thermal trip. NOTE! If you open the damper blade manually with the tool, be sure to release the damper back to the closed position before switching on power. 9. Connect ducts to the damper according to the instructions provided by the designer and the manufacturer. Use rivets of sufficient length (e.g. DIN Installation of fire damper into flexible building elements (gypsum board walls or similar) with fire classification EI 60 (Fig. 2 and Fig. 3) 1. Installation opening in the flexible wall must comply with the dimensions given in the table below. Size ØD (mm) Installation opening Ø (mm) The fire damper blade must be closed during installation. 3. Place the circular duct in the opening. 4. Fill the gap S between duct and wall opening on both sides by using fire-resistant mass. 5. Place the fire damper in the circular duct so, that the damper flange rests against building element. Use screws or anchors suited for gypsum board walls to fasten the damper to the building element through the bendable brackets on the flange. The damper must be fastened at 4 brackets at the minimum. The blade shaft can be placed in any position x10 or shorter) to lock fire damper to the duct. Note! Always check that damper blade can rotate freely and rivets/screws are out of the way. Access panel should be placed next to the fire damper to enable necessary cleaning and inspection. Suspend the ducts according to instructions from the manufacturer and ensure that the ductwork does not cause any load on the damper installation. 10. If the fire damper is used as an air transfer or air terminal device, it must be equipped with a protective grille. The distance between the grille and the damper blade in the open position must be at least 30 mm. In case of large fire dampers, an extension piece must be installed between the grille and the damper blade. A circular duct of suitable length can be used as an extension piece. 11. When dampers are to be mounted next to one another, the distance between the dampers should be 200 mm (Figure 4). Fläkt Woods 9938 EN All rights reserved.

5 Installation of fire damper outside building elements with fire classification EI 60 (Fig. 5-7) 1. Install the duct in the usual manner so that it penetrates the building element, and seal the openings ( or S) using an approved method. 2. Connect damper to duct according to the instructions provided by the designer or manufacturer. Use rivets of sufficient length (e.g. DIN x10 or shorter) to lock fire damper to the duct. Note! Always check that damper blade can rotate freely and rivets/screws are out of the way. Access panel should be installed next to the damper to enable necessary cleaning and inspection. 3. Support the duct installation so that there is no extra load on the fire damper. In horizontal installation use hangers (1) and in vertical use shaft hangers (2) or other approved methods to stabilize the damper (Figures 5-7). 4. Insulate the duct between wall and fire damper flange as shown in figures 5-7, so that the fire classification EI 60 is met. 5. Check the functioning of the fire damper and proper moving of the blade. Clean the damper, if necessary. Place plastic covers on the openings and keep them covered, until ducts are connected to the damper. 6. To reset the fuse mechanism: Turn the handle towards the OPEN position until the mechanism clicks and the blade locks into position. 7. anual function testing of the motorized fire damper can be performed with the tool delivered with the actuator. When connected to a power supply, function testing is done by using the switch of the thermal trip. NOTE! If you open the damper blade manually with the tool, be sure to release the damper back to the closed position before switching on power. 8. The fixings used to secure the fire damper and ventilation duct must have a fire resisting capacity that is at least as high as the fire classification of the penetrated building element (the fire resistance rating of a class EI 60 element is R 60, etc.). 9. If the fire damper is used as an air transfer or air terminal device, it must be equipped with a protective grille. The distance between the grille and the damper blade in the open position must be at least 30 mm. In case of large fire dampers, an extension piece must be installed between the grille and the damper blade. Fläkt Woods 9938 EN All rights reserved.
