Dampers with an electric drive are equipped with 24 V actuators. The same actuator
supports emergency operation and ventilation functions.
The elements of the system equipment are as follows: control panel, 24 V DC,
Manual emergency push button.
Activation in emergency mode may take place:
•
Automatically
– by means of an electric signal, sent by smoke or temperature
detectors.
•
Automatically
– from the Fire Alarm System (Polish acronym SAP)
•
Manually
– if fire has been noticed, a member of staff pushes the manual
emergency push button.
The continuity of power supply is imperative for this. Non-combustible cables are
used to connect elements of the system.
