8 Functional test
8.1 General
General
During operation at normal temperatures, the damper
blade is open. A functional test involves closing the
damper blade and opening it again.
CAUTION!
Danger of injury when reaching into the fire damper
while the damper blade is moving. Do not reach into
the fire damper while actuating the release mecha-
nism.
8.2 Functional test with automatic con-
trol unit
Functional test with automatic control unit
The function of fire dampers with a spring return
actuator can also be tested with an automatic control
unit. The control unit should have the following func-
tions:

Opening and closing fire dampers in regular inter-
vals (intervals to be set by the system owner)

Monitoring of the actuator running times

Issuing an alarm when the running times are
exceeded and when fire dampers close

Recording the test results
TROXNETCOM systems such as TNC-EASYCON-
TROL or AS-interface meet all these requirements. For
more informationen see www.troxtechnik.com .
TROXNETCOM systems allow for automatic functional
tests; they do not replace maintenance and cleaning,
which have to be carried out in regular intervals or
depending on the condition of the product. The docu-
mentation of test results makes trends visible, e.g. the
run time of actuators. They may also indicate the need
for additional measures which help to maintain the sys-
tem's function, e.g. removing heavy contamination (dust
in extract air systems).
