Design .01 with mechanical control can be complemented with a limit switch signalling of the
damper blade position "CLOSED". Limit switch is connected via damper casing (.01), cable is
connected directly to limit switch (.01v1) or limit switch is connected via mechanical control cover
(.01v2).
Design .01 with mechanical control can be complemented with a terminal switches signaling of
the damper blade position "CLOSED" or "OPEN". Limit switches are connected via damper
casing (.01), cables are connected directly to limit switches (.01v1) or limit switches are
connected via mechanical control cover (.01v2).

Design with an actuating mechanism BLF 230T or BLF 24T (further only "actuating mecha
nism"). After being connected to power supply AC/DC 24V or 230V, the actuating mechanism
displaces the damper blade into operation position "OPEN" and at the same time it prestretches
its back spring. When the actuating mechanism is under voltage, the damper blade is in the
position "OPEN" and the back spring is prestretched. 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 BAE 72BS),

Design with mechanical control with a thermal protective fuse which actuates the shutting device
within 120 seconds at latest after the nominal start temperature 72 °C has been reached.
Automatic initiation of the shutting device is not activated if the temperature does not exceed
70 °C. In case that other start temperatures are required, thermal fuses with nominal start
tempe 104 °C or +147 °C can be supplied (this requirement must be specified in the order).
