The Hikvision DS-K4H258-LZ is a professional-grade electromagnetic locking system designed specifically for doors that require a surface-mounted bracket solution—commonly glass doors and doors lacking a frame for flush installation. This model includes both the lock body and the essential LZ bracket, allowing secure and adjustable mounting on swing doors where typical electric bolt locks cannot be installed. With its impressive 280 kg (600 lbs) of holding force, fail-safe mechanism, and durable anodized aluminum housing, this electromagnetic lock delivers dependable access control in commercial, retail, and institutional applications.
Whether securing the glass front entrance of a corporate office or controlling access within a high-security facility, the DS-K4H258-LZ offers unmatched versatility and strength in one compact form factor. It works seamlessly with a wide variety of access control devices—including fingerprint terminals, keypads, RFID card readers, and biometric panels—and is trusted in professional deployments for its reliability, silent operation, and intelligent design.
280 kg (600 lbs) Electromagnetic Holding Strength
The DS-K4H258-LZ ensures superior locking performance through a powerful electromagnetic mechanism capable of securing single doors against significant force. Its 280 kg holding capacity makes it the go-to solution for facilities that require enhanced intrusion resistance, such as banks, data centers, laboratories, and government buildings.
Integrated LZ Bracket for Flexible Mounting
This model includes a factory-matched LZ bracket, which provides adjustable mounting flexibility for frameless glass doors or swing doors. The "L" bracket holds the electromagnet while the "Z" bracket anchors the armature plate, making it possible to mount the lock without modifying the door leaf or frame. This reduces installation time while ensuring strong and secure placement.
Fail-Safe Design with Automatic Unlock on Power Cut
In case of an emergency or power failure, the lock will automatically disengage to comply with fire exit and emergency egress requirements. This fail-safe design ensures that occupants can exit safely during crises without compromising the day-to-day locking performance.
Durable Anodized Aluminum Housing
The DS-K4H258-LZ is constructed from hardened anodized aluminum, offering both corrosion resistance and mechanical strength for long-term use in demanding environments. Its clean industrial finish also complements modern interior aesthetics, whether used in boardrooms, lobbies, or executive areas.
Silent, Maintenance-Free Operation
With no moving mechanical parts, this magnetic lock operates silently and does not require lubrication or regular part replacements. This feature makes it ideal for quiet zones such as hospitals, schools, research centers, and high-end office environments where discreet functionality is crucial.
Real-Time Lock Status Output (NO/NC)
The lock provides dry-contact signal output for real-time monitoring of door status. Integration with access control systems ensures that administrators can track door state, receive alerts, and log access events instantly, all contributing to smarter and more secure facility management.
Wide Compatibility with Access Control Systems
Operating on 12V DC power, the lock integrates smoothly with all standard access controllers, including Hikvision’s range of biometric terminals, keypads, and card readers. It is also compatible with third-party systems, offering flexibility in security infrastructure design.
