Design .01 with mechanical control can be complemented with a limit switch signalling of the
damper blade position "CLOSED". Cable is connected directly to limit switch.
Design .01 with mechanical control can be complemented with a terminal switches signaling of
the damper blade position "CLOSED" and "OPEN". Limit switches are connected via damper
casing, cables are connected directly to limit switches.

Mechanisms are produced in five designs
to
,
difference is only in size of inner spring, which closes
the fire damper. For the size of fire dampers is always
assigned the size of mechanism -
It is not
recommended to use different size of mechanism,
than given by the manufacturer, otherwise, there is a
risk of fire damper destruction.
Design with mechanical control with a thermal protective fuse which actuates the shutting device,
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 tempe104°C or +147°C can
be supplied (this requirement must be specified in the order).
