■ Design with manual control with a thermal fuse which
actuates the shutting device, after the nominal activation
temperature 72°C has been reached.
■ Automatic initiation of the manual control is not activated
if the temperature does not exceed 70°C.
■ In case that other activation temperatures are required,
thermal fuses with nominal activation temperature
+104°C or +147°C can be supplied (this requirement must
be specified in the order).
Design .01
ATTENTION:
■ Manual controls are produced in five sizes M1 to M5,
difference is only in size of a closing spring, which closes
the fire damper.
■ For the size of fire dampers is always assigned the size of
the manual control → see page 24
■ It is not recommended to use different size of the manual
control than given by the manufacturer, otherwise there
is a risk of damaging the fire damper.
