Hikvision Access Control (DS-K4H250-LZ)

The Hikvision Access Control (DS-K4H250-LZ)  is a high-quality, professional-grade installation accessory designed specifically for the secure mounting of magnetic locks on in-swinging doors. As part of Hikvision’s Pro Series access control lineup, this LZ-bracket set is engineered to provide the structural stability and precise alignment required for high-security environments. It is a critical component for ensuring that electromagnetic locks function at their rated holding force, providing a reliable and durable solution for residential, commercial, and industrial doorway security.

The Hikvision Access Control (DS-K4H250-LZ) is specifically designed to be compatible with the DS-K4H250 series of single-door magnetic locks, which typically feature a holding force of 270kg (600lbs). In a standard door configuration, magnetic locks are easily mounted on doors that swing outward. However, for doors that swing inward (toward the secure area), a specialized bracket is required to position the magnet and the armature plate correctly. The “L” bracket is used to mount the electromagnet to the door frame, while the “Z” bracket is used to mount the armature plate to the inward-swinging door leaf. Together, they allow the lock to achieve full magnetic contact, ensuring the door remains firmly sealed when energized.

Durability and strength are the hallmarks of the Pro Series hardware. The Hikvision Access Control (DS-K4H250-LZ) is manufactured from high-strength, sandblasted aldary (aluminum alloy). This material is chosen for its excellent strength-to-weight ratio and its natural resistance to corrosion and oxidation. The sandblasted finish not only provides a sleek, professional silver aesthetic that matches modern office decor but also adds a layer of wear resistance, ensuring the bracket does not peel or rust over years of constant use. This robust construction is essential for maintaining the alignment of the lock, as even a minor shift in the bracket could result in a significant drop in holding force.

Precision engineering ensures that the installation process is as efficient as possible. The bracket features multiple pre-drilled mounting holes and adjustment slots, allowing installers to fine-tune the position of the armature plate. This adjustability is vital for compensating for slight irregularities in door frames or hinges, ensuring that the armature plate sits perfectly flush against the electromagnet. A flush contact is the only way to guarantee that the 270kg holding force is fully realized, preventing the door from being forced open. The bracket’s design also incorporates a cable management path to keep wiring neat and protected from tampering or accidental damage.

Safety and compliance are integrated into the design of this bracket set. It is built to withstand the rigors of high-traffic areas where doors are opened and closed hundreds of times per day. The high-quality aluminum alloy ensures that the bracket will not deform under the constant magnetic pull or the physical stress of door operation. Furthermore, the professional finish and hidden screw designs help prevent unauthorized tampering, making it a dependable choice for sensitive areas such as server rooms, laboratory entrances, and executive offices.

The Hikvision Access Control (DS-K4H250-LZ) is a versatile solution that works seamlessly within the broader Hikvision access control ecosystem. Whether integrated with fingerprint terminals, card readers, or facial recognition controllers, the mechanical reliability provided by this bracket ensures that the electronic commands are backed by a solid physical barrier. Its compact yet sturdy design ensures it does not interfere with the aesthetic of the doorway, making it suitable for high-end commercial interiors while providing the rugged performance needed for industrial sites.
