DM-S is always equipped by actuating mechanism BFL (BFN, BF) 24-T (further only "actuating
mechanism").  After  being  connected  to  power  supply  AC/DC  24V,  the  actuating  mechanism
displaces the damper blade into operation position "OPEN" and at the same time it pre-stretches
its  back  spring.  When  the  actuating  mechanism  is  under  voltage,  the  damper  blade  is  in  the
position "OPEN" and the back spring is pre-stretched. Time needed for full opening of the flap
blade  from  the  position  "CLOSED"  to  the  position  "OPEN"  is  maximum  140s.  If  the  actuating
power  supply  is  cut  off  (due  to  loss  of  supply  voltage,  activation  of  thermoelectrical  actuating
mechanism  or  pushing  the  reset  button  on  the  thermoelectrical  starting  mechanism  BAT),  the
back  spring  displaces  the  damper  blade  into  the  breakdown  position  "CLOSED".  The  time  of
displacing the blade from the position "OPEN" to the position "CLOSED" takes maximum 16 s. In
case  that  the  power  supply  is  restored  again  (the  blade  can  be  in  any  position),  the  actuating
mechanism starts to re-displace the damper blade into the position "OPEN". A thermoelectrical
starting mechanism BAT, which contains two thermal fuses Tf1 and Tf2, is a part of the actuating
mechanism. These fuses are activated when tempe72 °C has been exceeded (the fuse
Tf1 when the temperature around the damper and the fuses Tf2 when the temperature inside the
air-conditioning piping has been exceeded). After the thermal fuse Tf1 or Tf2 has been activated,
the power supply is permanently and irreversibly cut off and the actuating mechanism, by means
of the pre-stretched spring, displaces the damper blade into the breakdown position "CLOSED".
