or 95°C inside the fire damper casing.
3 Temperature cut-off approx. 70°C
outside the fire damper casing.

OPEN-CLOSED position indicator.
The illustration shows the
de-energised operating position
where the fire dampers are closed.
•
The switches on the connection cables
can be removed if they are not being
used.
•
Due to their in-built thermal release
elements, all actuators must be stored
at temperatures not exceeding 50°C!
