8 Functional test
General
During operation at normal temperatures, the damper
blade is open. A functional test involves closing the
damper blade and opening it again.
8.1 Fire damper with spring return
actuator
Status indicator
Fig. 7: Thermoelectric release mechanism BAT
1 Push button for functional test
2 Indicator light
The indicator light (2) for the thermoelectric release
mechanism is illuminated when all of the following con-
ditions apply:

Power is being supplied.

The thermal fuses are intact.

The push button is not being pushed.
Closing/opening the damper blade with spring
return actuator
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.
Requirement

Power is being supplied
1. Push toggle switch
①
.
ð
This interrupts the power supply, and the
damper blade closes.
2. Release the push button
①
.
ð
Power is supplied again, and the damper
blade opens.
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).
