Fire damper - FDMQ 120
TPM 162/22
■
If the damper is equipped with limit switches and these
switches are not used during operation (e.g. because of a
project change), they can be left on the damper and not
connected (they need not be dismounted).
■
On the other hand, if the limit switch is to be added to the
damper design, the change can be implemented by
adding the limit switch to the base plate of the damper.
■
These facts must be recorded in the respective operation
documentation of the damper (record books of the
damper, fire logs, etc.) and subsequently, adequate
function checks must be carried out.
Limit switches
■
The damper casing shall not be deformed in the course of
bricking in.
■
Once the damper is built in, the damper blade shall not
grind on the damper casing during opening or closing.

■
Assembly, maintenance and damper function check can
be done only by qualified and trained person, i.e.
“AUTHORIZED PERSON” according to the manufacturer
documentation. All works done on the fire dampers must
be done according international and local norms and laws.
■
All effective safety standards and directives must be obse-
rved during damper assembly.
■
To ensure reliable damper function it is necessary to avoid
blocking the actuating mechanism and contact surfaces
with collected dust, fibre and sticky materials and solvents.
■
Flange and screw joints must be conductively connected
to protect against dangerous contact. 2 galvanized lock
washers that are placed under the head of one screw and
a fastened nut are used for conductive connection.
VI. ASSEMBLY, ATTENDANCE AND MAINTENANCE
Assembly
■
A special wrench (part of the actuator) can be used to
manually turn the damper blade to any position. When
the wrench is turned in the direction of the arrow, the
damper blade rotates to its open position. As the blade
rotation is stopped, in every position, the actuator will be
locked. Unlocking is possible even manually as per
instructions on the actuator, or by the activation of the
supply voltage.
■
If the actuator is manually locked, the damper blade will
not close in the event of a fire after the activation of the
thermoelectric activation device BAT. To restore correct
damper operation, the actuator must be unlocked
(manually or by applying power supply).
