In order to check the proper functioning of fire damper, in particular:
a.
Make a visual inspection of the interior of fire damper, determine the condition of the baffle and seal, whether
there are no damage or dirt that could block the fire baffle during closing.
a.
Check the fire damper without disconnecting the supply voltage from the actuator.
b.
The opening and closing test should be carried out by positioning the baffle
from control system („open” and
„closed” position read on the position indicator located on the actuator).
c.
After doing the above, leave the fire damper in the open position.
d.
Make a control protocol.

Symptoms of
malfunction
Causes of malfunction
How to remove malfunction
1
No signaling
opening/closing fire
damper
1. Failure to fully open the
baffle (wrong connected
ventilation duct)
2. Improperly connected wires
of limit switch
3. Damaged actuator
1. Removing the cause of blocking
damper baffle
2. Correct wiring
3 . Replacing the actuator with a
new one (after consulting with fire
damper`s manufacturer)
2
No actuator response
after connecting power
1 .Damaged actuator
2. Damaged temperature
sensor
3. Locked baffle
1. Replacing the actuator with a
new one (after consulting with fire
damper`s manufacturer)
2. Replacing the temperature
sensor to a new one
3 .Removing the cause of blocking
baffle
3
No possibility of opening
the fire damper with
actuator by key
1 .Broken mechanism in the
actuator (too rapid rotation)
2.Locked baffle
1. Replacing the actuator with a
new one (after consulting with fire
damper`s manufacturer)
2. Removing the cause of blocking
baffle
