FAQs
Installation begins with selecting the DK 7320.721 compatible TS 8 or DK-TS enclosure. The package includes two adaptors for glazed doors, cable clamps, an adaptor for profile half-cylinders, and a 3 m RJ12 connection cable plus assembly parts. Mount the handle to align with the CMC III control unit and route the RJ12 to the IoT interface, ensuring proper grounding and cable management to maintain IP-rated integrity.
The Master key function enables controlled, auditable access for authorized personnel and includes an emergency open capability. This reduces downtime during maintenance, enhances security by preventing unauthorized entry, and supports rapid incident response without compromising enclosure integrity.
Yes. The DK 7320.721 is designed to integrate with CMC III control units and IoT interfaces, supporting up to 16 participants per IoT interface, 2 participating PU compact units, and up to 16 PU units overall. This setup enables centralized monitoring, control, and data logging for enclosure health and access events.
Key considerations include correct door adaptation using the supplied adaptors, secure cable routing via clamps, and ensuring the RJ12 connection cable is properly shielded and terminated. Verify compatibility with glazed doors and profile half-cylinders, and confirm the system configuration aligns with your site’s safety and IP requirements while following manufacturer guidelines.
Regular maintenance is simplified by centralized monitoring via the CMC III IoT interface, reducing unscheduled downtime. The integrated master-key functionality minimizes security incidents, while the included hardware accelerates installation, cutting commissioning time. Over the lifecycle, this translates to lower total cost of ownership and faster time-to-production for automated lines.
