Vault door There are multiple lock systems, each with its own unique design and assembly method. Therefore, customers should not simply follow others’ practices; instead, they should pay close attention to the recommendations of the manufacturer’s qualified technical experts. If a lock malfunctions, do not attempt to force it open—instead, contact a professional technician as soon as possible for assistance. The manufacturer is equipped to resolve such issues efficiently.

　　A fingerprint safe door is a new type of safe door that, in addition to a conventional mechanical lock, is equipped with a fingerprint lock. The fingerprint lock comprises a power supply, a fingerprint reader, a central processing unit, and an electromagnetic lock, all connected in sequence. The fingerprint reader is mounted on the exterior side of the wall, the CPU is located on the interior side, and the electromagnetic lock is installed on the inner surface of the door leaf, with its bolt aligned with a slot on the control lever. When the electromagnetic lock is engaged, its bolt inserts into the slot on the control lever, thereby restricting the lever’s movement. In this way, the door can be opened only when both the mechanical lock and the fingerprint lock are unlocked, significantly enhancing security. This design is particularly well suited for critical facilities such as safes.

　　Installation Steps for Fingerprint Door Lock

　　1. Based on the dimensions of the wall opening for the arch-top door, leave an appropriate door opening and embed connecting reinforcing bars.

　　2. Use lifting equipment to position the archway at the doorway, adjust its vertical and horizontal alignment to within 2 mm, and then use steel plates to flatten it.

　　3. Weld the diagonal bracing for the vault door frame using the reserved reinforcing bars.

　　4. Perform trial opening and closing adjustments to ensure the door leaf opens freely and the lock engages reliably, with the door leaf coming to a secure stop upon operation.

　　5. Fill the gap between the door frame and the wall with cement mortar.

　　Methods for Opening and Closing the Vault Door

　　Gold jewelry stores and security companies typically install vault doors; private villas are often equipped with gold vaults and corresponding vault doors, most of which offer Grade B protection. For banks, the preferred choice is a Grade C vault door with even higher protection standards. Households, warehouses, and small businesses usually opt for M-grade vault doors, which are more affordable and provide moderate protection—enough to deter ordinary thieves but not impervious to determined break-ins. Therefore, the selection of a vault door should be based on the specific conditions of use. Different grades offer varying levels of protection and come at different price points, naturally resulting in differences in the cost of vault doors.

　　Customizing a vault door allows for cost control because the product’s various specifications can be tailored to meet specific requirements, such as the door’s material and thickness, whether it includes a security door and a buffer door, whether the lock requires single-person operation or dual-person authorization, or even multi-person access management; additional considerations include fingerprint reader requirements and whether a palm-vein scanner should be installed.
