commissioning
A functional test should be carried out before com-
missioning, then every 12 months and after any
modification, e.g. repair.
Without smoke
Press the test/reset push button on the duct smoke
detector or in the engineering room (option).
The voltage supply to the smoke detector which is
attached to the fire damper or smoke protection
damper is interrupted, and the damper closes as a
consequence.
Once the push button has been released, the
damper OPENS, either by means of a spring return
actuator or a pneumatic actuator.
Note
Fire dampers whose release mechanism
includes electromagnets can be opened
manually.
With smoke
Spray test gas into the duct through the opening
right next to the duct smoke detector
If the threshold value is exceeded, the voltage sup-
ply to the duct smoke detector which is attached to
the fire damper or smoke protection damper is in-
terrupted, and the damper closes as a
consequence.
To reopen the damper after the sensor head has
become free of smoke, press the test/reset push
button on the duct smoke detector.
Once the push button has been released, the
damper OPENS, either by means of a spring return
actuator or a pneumatic actuator.
Note
Fire dampers whose release mechanism
includes electromagnets can be opened
manually.
All operating, warning and alarm functions are de-
scribed on page 4.
