The Hikvision DS-K4H250D is a premium-grade double-door magnetic lock designed to provide high-performance access control for wide entryways and dual-door configurations. Equipped with an impressive 2 × 300 kg holding force, this lock delivers exceptional strength, advanced fail-safe functionality, and unmatched compatibility with access control systems from Hikvision and other leading providers. Built to handle demanding environments, this lock is ideal for securing commercial complexes, institutional buildings, data centers, retail entrances, and other high-traffic access points where dual-door security is critical.
Engineered with high-quality anodized aluminum and built-in signal output for door status monitoring, the DS-K4H250D is both rugged and intelligent. Its surface-mounted design ensures quick and secure installation across various door types, while its sleek and silent operation makes it suitable for areas requiring discreet access control.
Dual 300 kg Holding Force for Enhanced Double-Door Security
The DS-K4H250D features two high-powered electromagnetic locking units, each delivering a holding force of 300 kg. This provides a combined holding force of 600 kg, enabling secure closure for both leaves of a double-door configuration. It is ideal for wide entryways where reinforced access control is essential.
Fail-safe Design for Emergency Unlocking
This lock features fail-safe operation, meaning it will unlock automatically in the event of a power failure. This is a crucial safety feature for emergency scenarios, as it allows occupants to exit the premises without obstruction, ensuring full compliance with building and fire codes.
High-Durability Anodized Aluminum Construction
Made from premium anodized aluminum, the lock body resists corrosion, wear, and harsh environmental conditions. It retains both structural integrity and aesthetic quality over time, even in high-humidity or industrial environments.
Real-time Door Monitoring via Dry Contact Output
The DS-K4H250D includes NO/NC dry contact signal output that enables real-time monitoring of door status. It seamlessly integrates with access control panels to report whether doors are securely closed, held open, or being tampered with, enhancing situational awareness and system intelligence.
Quiet, Maintenance-free Magnetic Operation
The lock uses electromagnetic force rather than mechanical latches or bolts, ensuring silent operation and eliminating mechanical wear over time. This allows the unit to provide reliable, long-term service with virtually no maintenance required.
Surface-mounted for Versatile Installation
The lock can be quickly installed on wood, metal, or glass doors (with the use of additional brackets). Its surface-mounted design makes it ideal for both new constructions and retrofitted security upgrades where simplicity and reliability are key.
Seamless Integration with All Major Access Control Systems
The DS-K4H250D is fully compatible with Hikvision access terminals, biometric readers, and card/fingerprint/keypad systems. It can also be integrated into third-party access control environments using standard dry contact signal configurations.
