Functional description
A functional test should be carried out before commissioning, then once per year and after any modification, e.g. repair.
Without smoke
Press Reset/Test 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 due to 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 an opening right before the duct smoke detector
If the threshold value is exceeded, the voltage supply to the duct smoke detector which is attached to the fire damper or smoke protection damper is interrupted, and the damper closes as a consequence.
To re-open 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 due to a spring return actuator or a pneumatic actuator.
Note: Fire dampers whose release mechanism includes electromagnets can be opened manually.
Duct smoke detector (smoke detection based on the principle of light scattering) to prevent smoke from spreading through the ducts of ventilation and air conditioning systems.
For controlling and releasing fire dampers and smoke protection dampers with general building inspectorate licence and fitted with an electric or electric-pneumatic release mechanism (power off to close).
