[no symbol] – trigger for 72°C
ZBAE95 – thermoelectric trigger 95°C
ZBAT95 – thermoelectric trigger at 95°C
T93-95 – thermal trigger for 95°C
Position of the control mechanism
[no symbol] – perpendicular to the axis of damper rotation
WOK – along the axis of damper rotation
Axis of rotation of the damper
[no symbol] - horizontal axis of rotation
PP – vertical axis of rotation
PP_D – vertical axis of rotation - mechanism at the bottom of the damper
PP_G – vertical axis of rotation - mechanism at the top of the damper
Extended damper casing
[no symbol] – standard casing length
400 – casing with a length of 400 mm
External perimeter seals
[no symbol] – version without seals
UKW – version with external seals

* – for damper with RST-KW1 mechanism, a trigger control mechanism is mounted as standard along the axis of rotation –
exception
6. INSTALLATION OF THE FIRE DAMPER
NOTE
During the installation of a fire damper and while conducting finishing work, you should allow for
the possibility of later access to the fire damper and removal of the release and control mechanism
in order to carry out possible service work and technical inspections.
The mcr FID PRO fire dampers may be installed in the following space dividing elements (walls or structural floors):
masonry/concrete walls with the minimum thickness of 120 mm
brickwork walls or blockwork walls with the minimum thickness of 125 mm
walls made of boards with the minimum thickness of 125 mm
structural floors with the minimum thickness of 150 mm
