A Door Interlock is a control arrangement that prevents two or more doors from being open simultaneously, releasing the next door only after the previous one is secured. In data centers interlocks enforce airlock and security-vestibule behavior, maintaining pressure separation and anti-tailgating control between corridors, data halls and clean or secure zones.
