housed tolerance of 24V±10% or 230V±10%. Power supply devices other than listed above may cause
malfunction and will not be covered by the warranty conditions.
RST/KW1 release and control mechanism
In the RST/KW1/S manufacturing version, the limit switches are installed on the mechanism itself. Electrical
connection is carried out by connecting the wires (marked accordingly) to the electrical wiring system. The fusible
release link is installed on the mechanism itself. The dampers with the RST/KW1/230I, RST/KW1/230P
mechanisms, are supplied with the RST/KW1/24... triggering and control mechanism, together with the 230/24V
transformer module type MP230/24.

Warning! - Location of limit switches of the mechanism was shown for the damper safety position
For proper operation of a device equipped with electrical actuators, it is recommended that the rated voltage housed
tolerance of 24V±2% or 230V±2%. Power supply devices other than listed above may cause malfunction and will
not be covered by the warranty conditions.
RST release and control mechanism
In the RST manufacturing version, the fusible release link is installed on the fire damper’s partition. Mainspring
and limit switches are located in the KW1 housing.

7. TRANSPORT AND STORAGE CONDITIONS
Fire dampers are packed in cardboard boxes or placed on pallets. They are wrapped in plastic film or other protective
material in order to protect them against damage. Fire dampers may be transported using any means of transport,
provided that protection against the weather is ensured. Fire dampers placed on transport vehicles should be
secured in such a way that they do not move during transport. Before installing fire dampers, conduct visual
inspection of each unit. Do not move a fire damper by its connection cable or place it in such a way that its weight is
supported on the release and control mechanism. Fire dampers cannot be hit or dropped. When moving and
