Door Interlocking System can be fully programmed for up to eight doors, ensuring that only one door remains open at a time. This prevents simultaneous access to change rooms and airlocks, thereby reducing contamination risks. Equipped with audio-visual indicators such as LEDs and buzzers, the system provides instant notifications to administrators of any door activity. With its state-of-the-art interlock technology, it simplifies monitoring and regulating traffic flow while maintaining controlled air pressure. Ideal for pharmaceutical facilities and other critical environments, this system ensures safety, compliance, and contamination control
