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
temperature + 104 °C or +147 °C can be supplied (this requirement must be specified in the order).
Design .01 with mechanical control can be complemented with a limit switch signaling of the
damper blade position "CLOSED".
