Description

RSKENormally closed single louvre fire safety dampers RSKMNormally closed multiple-louvre fire safety dampers
   
USE

The dampers are intended for integration into smoke control systems of buildings and structures of various purpose and designed for extraction of combustion products from the spaces of floor corridors, hallways, air locks etc. The dampers can be used as smoke dampers in emergency smoke exhaust ventilation systems in the event of a fire to support evacuation of people from the building at the initial phase of the fire occurring in any of the building spaces. The RSKE/RSKM multi-purpose fire safety smoke dampers are rated to resist fire for 180 minutes (E 180) at the temperature of 600 °C.

DESIGN

The damper casing is made of galvanised steel 1.5 mm thick. The dampers are available in the wall-mounted or duct-mounted variant which have either one or two attachment flanges.

CONTROL AND MODIFICATIONS

The units are available in two control options (with an electric magnet and with an electric actuator in different configurations):

THE DAMPER WITH AN ELECTRIC MAGNET (220 OR 24 V) The damper opens via a spring when the electric magnet is energized. When the damper reaches the end position, a limit switch opens the circuit disconnecting the electric magnet from the power mains. The electric magnet must not remain energized for more than 2 seconds. The damper is reset to the safety (closed) position manually by means of a handle. The damper equipped with an electric magnet has a special button for testing the unit performance.

THE DAMPER WITH A 230 OR 24 V ELECTRIC ACTUATOR AND A RETURN SPRING The flaps are automatically set to the normal (closed) position when applying voltage to the electric actuator. On a fire alarm signal the electric actuator is de-energized causing its return spring to set the damper to an open position. The electric actuator is equipped with a contact group to signal its end positions. The damper can also be controlled manually and fixed in any position. The unit can be unlocked either manually using a hex wrench or automatically upon power-up.

THE DAMPER WITH WITH A 230 OR 24 V ELECTRIC ACTUATOR AND TWO-WIRE CONTROL The damper flap is set from the "Open" to the "Closed" position by an external command sending the voltage phase from one actuator contact to the other. The electric actuator is equipped with a contact group to signal its end positions. The damper can be controlled manually by means of a hex key.

Note. The RSKM dampers with a height of 300 and 350 mm have one louvre. The main difference between the RSKM and the RSKE dampers with a similar height of 300 and 350 mm is that the method of fastening the flap, which ensures a smaller overhang of the flap beyond the RSKM valve.

MOUNTING

The dampers are not intended for installation in air ducts and ducts of spaces with fire and explosion hazard categories A and in local exhaust systems designed for extraction of flammable and explosive mixtures as well as in systems containing environments more aggressive to plain carbon steels than air or those containing sticky and fibrous materials. Fire safety dampers are only intended for installation in systems subjected to regular cleaning to prevent formation of flammable deposits. The damper must be installed into the building envelope structure in accordance with the applicable standards and regulations. The seal fire resistance must be at least equal to that of the building envelope. When preparing for installation the damper casing should be fitted with wooden spreader bars to prevent deformation, torsional twisting or geometry perturbation of the casing which may result in louvre jamming and, eventually, loss of the damper functionality.

Upon completion of the damper brickwork envelope in the smoke shaft, fire division wall or flooring and complete cure (setting) of the sealing, remove the wooden spreader bars and check the louvre for free and frictionless opening. Ground the damper, connect the electromagnet or electric actuator (depending on the modification) to the automatic fire-fighting system and test the damper actuation.

VANDAL-PROOF MESH

The RSKE/RSKM dampers can be equipped with a vandal-proof mesh.

ALUMINIUM DECORATIVE GRILLE

The unit can be equipped with a decorative grille made of aluminium for a more aesthetic appearance. The grille has a single horizontal row of non-adjustable air flow guides fixed at 45 degrees. The grille is polymer coated and anodised for extra protection against the weather elements. To enable the decorative grille installation, the damper must be embedded at least 40 mm deep into the wall as measured from the wall face to the damper flange. NOTE: While selecting the aluminium decorative grille mind the wall opening dimensions.

RD, RD1 SMOKE EXHAUST GRILLES

The RSKE/RSKM dampers can be additionally equipped with a smoke exhaust grille. The smoke exhaust grille is used when it is necessary to entirely hide the damper internals from view and if there are no strict requirements to external design. The smoke exhaust grille also doubles as unauthorized access protection for the damper and its actuator. The grille has a single horizontal row of non-adjustable air flow guides fixed at 45 degrees. The grille can be made of galvanized steel (Ts), carbon steel with a special coating (M), stainless steel (N) or aluminium (A). The grille is attached directly to the damper flange by means of self-tapping screws with the flaps facing outward and does not require any additional recessing of the damper.
