Smoke damper EKO-SRB1

Transcription

1 Smoke damper EKO-SRB1 Description The EKO-SRB1 smoke damper is a CE-approved damper in fire class E60 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 installation in ducts. Alternatively, it can be installed after air treatment equipment serving more than one fire cell. CE-approval The EKO-SRB1 smoke damper has been tested by SP and approved by SITAC, CE-marking 0402-CPD- SC Design The EKO-SRB1 smoke damper as delivered is prepared for insulation and with circular duct connection. The damper has a factory-mounted electrical motor with spring return, end position contacts and thermal sensor. The standard EKO-SRB1 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. The blade axle must nevertheless always be mounted horizontally. Sizes The EKO-SRB1 smoke damper is manufactured in nine standard sizes from Ø 100 to Ø 630 mm. Product data EKO-SRB1 Sizes Ø 100 Ø 630 mm. Material of manufacture: galvanized, aluzinc coated or stainless sheet steel. Fire-technical class in compliance with SS-EN 156:2010 E 60 (ve ho i < > o) SC Testing and classification in compliance with EN and EN CE-marking 0402-CPD-SC The damper conforms to air tightness class 3 and the casing conforms to air tightness class B according to EN 1751:1998. The damper conforms to air tightness class 3 and pressure class B. The differential pressure over a closed damper can be 20 Pa, corresponding to pressure class B. Conforms to environmental class C2.

2 Motors The EKO-SRB1 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. 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. Cleaning We recommend preventive maintenance of the damper according to the needs of the installation. Damper blades and body (interior) should be cleaned by brushing, vacuum cleaning or wiping down. NOTE! No water or other liquid may be used. 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. Other components, such as couplings and fire collars, must be ordered separately. Accessories EKO-GIS Plasterboard wall sleeve, excl. fire sealant kit. EKO-KER Fire sealing kit for wall.

5 Mounting instructions EKO-SRB1 Structural element wall or floor structure of fire-technical class EI 60. Suspension Ø A+55 EKO- SRB1 EKO- SRB1 Fire sealant* Fire sealant* Important! The smoke damper should always be installed with the pivot shaft horizontal. 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). 2. Mount the damper in the duct. The minimum gap between dampers must be 200 mm (when installed side by side). No gaps between the damper and a firecontaining structural element. The pivot shaft of the damper blade must always be installed horizontally. 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. * 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. 5 Tel , Fax , info@ekovent.se, 5 (5)
