Caution:
For proper operation of a device equipped with electrical actuators, it is recommended that the rated voltage 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 trigger control gear
The RST/KW1/S version has the limit switches installed in the gear itself. The electrical connections shall be made
by connecting the properly labelled conductors to the electrical system. A fusible trigger is installed in the gear. 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.

Caution! - The location of the limit switches is showed for the fire damper in the safety position.
The RST/KW1 trigger control can work with the MP230/24 module. If the MP230/24 module is installed, the fire
damper can be powered/controlled with voltage 230 V AC.
The proper performance of the device with electric actuators requires the rated supply voltage of 24 V ±2% or 230 V
±2%, as applicable. Other voltage values may cause operating malfunctions, that are not covered by the product
warranty.
