Smoke ventilation control unit RZN 4408-K
The RZN 4408-K smoke ventilation control unit is designed for smoke extraction and natural ventilation systems in residential, commercial and public buildings. It combines high functionality with reliability in emergency situations. In the event of a fire, the control unit immediately responds to a signal from the smoke detector, automatically activating the actuators of smoke ventilation windows. It also enables daily room ventilation and works with a rain sensor that automatically closes windows in the event of precipitation. Thanks to its built-in emergency power supply, the control unit operates continuously for 72 hours in monitoring mode, ensuring complete safety even in the event of a power failure.
