Fire/smoke damper EKO- Description The EKO- fire/smoke damper is a CE-approved damper intended for fire compartmentation or protection against the spread of fire and smoke in ventilation installations. The damper is designed in compliance with current regulations. The damper is intended for in-wall installation in fire-containment sections conforming to fire-technical class up to EI 60. The ventilation duct can be left without any fire insulation whatever. A wire mesh grille should always be fitted when the damper is not connected to the ducting. CE-approval The EKO- fire/smoke damper has been tested by SP and approved by SP Certifiering and CE-marking 0402-CPR-SC0845-13. Design The EKO- fire/smoke damper is available with circular duct connection as standard. The damper has a factory-mounted electrical motor with spring return, end position contacts and thermal sensor. The standard EKO- is manufactured of galvanized sheet steel (C2) with damper blades and casing of fire-resistant material. Alternatively, the damper can be made of aluzinc (C4) or stainless steel for a higher corrosivity class. The damper is fitted with a gasket to seal the air side. There is also a sealing strip on the damper that expands and seals if the damper is exposed to heat. Temperature Since the EKO- damper frame is fitted with sealing strips that expand to seal off in the event of fire, the operating temperature must not exceed 70 C. Sizes The EKO- fire/smoke damper is manufactured in seven standard sizes from Ø 100 to Ø 400 mm. For diameters between 400 mm and 630 mm use EKO-SRBG2. For diameters over 630 mm use EKO- JBG2 with circular duct connection. Product data EKO- Sizes Ø 100 Ø 400 mm (EKO-). Sizes Ø 500 Ø 630 mm (EKO-SRBG2). Nipple connection in accordance with Swedish standard. Material of manufacture: galvanized, aluzinc coated or stainless sheet steel. Fire-technical class in compliance with SS-EN 15650:2010 EI 60 (ve ho i < > o) SC 20000 Testing and classification in compliance with EN 1366-2 and EN 13501-3. CE-marking 0402-CPR-SC0845-13. The damper conforms to air tightness class 2 and the casing conforms to air tightness class B according to EN 1751:1998. The damper conforms to air tightness class 2 and pressure class B according to AMA VVS & Kyl 12. The differential pressure over a closed damper can be 2500 Pa, corresponding to pressure class B. Conforms to environmental class C2. AMA VVS code QJC.2 Fire/smoke damper EKO-. EI 60 S Tel +46 40 42 16 00, Fax +46 40 421 25 18, info@ekovent.se, www.ekovent.com 2017-10 1 (9)
Motors The EKO- is supplied with a 24 V or 230 V electrical safety motor supplemented with a thermal sensor and test button for manual testing of functioning in situ. If the temperature exceeds 70 C inside or outside the damper, the sensor cuts off the power to the motor and the fire damper is closed. The same thing happens in the event of a power cut. A 24 V motor is always used together with the monitoring units EKO-KE 2-16 and EKOTME/TSE. A 230 V motor is used for the EKO-MKE/SKE monitoring unit. Note that the damper must always be delivered with a factory-mounted safety motor if P-certification is to be valid. Maintenance External and internal inspection Check electricity cables to the motor, smoke detectors and thermal sensor to ensure that they are not damaged. Check the damper casing, the motor attachment, damper blades and sealing strip to ensure that no damage has occurred. Function control Check that the damper is fully open when operating, closes and opens fully when tested, and closes completely when power is cut off. Otherwise follow the instructions for the EKO MKE/SKE/KE/TME/ TSE control and monitoring system. Note After inspection the fire damper should be left in normal working position. Installation Installation must always be done in accordance with the supplied installation instructions. An installation device for attaching the damper to a wall and angle brackets for ducts are included in the damper delivery. Other components, such as couplings and fire collars, must be ordered separately. The size of the hole is always the dimension of the damper + 55 mm. The pivot shaft of the damper can be installed in any position. Accessories EKO-GIS Plasterboard wall sleeve, excl. fire sealant kit. EKO-KER Fire sealing kit for wall.

Mounting instructions EKO- Structural element wall or floor structure of fire-technical class EI 60. Suspension Ø A+55 EKO- EKO- EKO- Fire sealant* Fire sealant* 1. The duct system should be suspended and insulated in accordance with the fire resistance of the structural element in which the hole is made (EI 60). Insulation of the ventilation duct must be done in accordance with Installationsbrandskydd Ventilation Rör section 21.3.4 (ISBN: 978-91-633-1723-1) corresponding to the fire resistance of the structural element in which the hole is made (EI 60). NOTE! The insulation does not need to cover the damper. 2. Mount the damper in the duct. No gaps between the damper and a fire-containing structural element. Screw the damper to the duct with self-drilling screws. Check that the movement of the blade is not obstructed by the screws. 3. Mount the thermal sensor with the sensor bulb in the air flow, ensuring that it does not obstruct the movement of the damper blade. 4. The following minimum dimensions must be observed when mounting: Minimum distance between dampers: 200 mm. Minimum distance to wall/floor: 75 mm. The pivot shaft of the damper can be installed in any position. * Fire sealing must be done using an approved method that complies with the relevant firetechnical class, e.g. EKO-KER, EKO-GIS and fire protection sealant.
