The Hikvision DS-K4H258D Two-Door Magnetic Lock is a powerful, commercial-grade electromagnetic locking solution engineered to secure two independent doorways with high force and zero mechanical wear. Perfectly suited for environments that demand robust physical access control—such as office complexes, educational institutions, industrial zones, and government facilities—this dual-lock system combines performance, safety, and reliability with Hikvision’s globally trusted engineering.
Whether you need to manage traffic through dual-entry lobbies, control access at hallway intersections, or secure both sides of an interior passage, the DS-K4H258D offers strong holding force, fail-safe emergency release, and integrated signal outputs—all while minimizing operational noise and mechanical wear. For facility managers, security integrators, and end-users looking for dependable, professional-grade door control, this lock stands out as a top-tier solution.
Independent High-Strength Locking for Two Doors
The DS-K4H258D contains two fully independent electromagnetic locking units, each capable of delivering 280 kg (600 lbs) of holding force. This makes it ideal for installations involving dual single doors or double-leaf door configurations. Both locks operate simultaneously or independently, depending on your access control design, ensuring optimal flexibility for security planning.
Fail-Safe Security for Emergency Situations
Engineered with a fail-safe design, both magnetic locks disengage automatically in the event of a power outage or fire alarm activation. This guarantees full compliance with emergency egress and building safety codes, making the DS-K4H258D ideal for locations where rapid evacuation routes must remain accessible without manual intervention.
Silent, Maintenance-Free Operation
Since magnetic locks contain no moving mechanical parts, the DS-K4H258D operates silently and suffers virtually no wear and tear over time. It provides a long-term, low-maintenance solution especially suited to high-traffic facilities where consistent reliability and minimal servicing are essential.
Durable Anodized Aluminum Alloy Housing
Each unit is encased in corrosion-resistant anodized aluminum, ensuring durability under daily use and resistance to tampering, moisture, and wear. This makes the lock appropriate for interior commercial settings and semi-exposed entry points where aesthetics and robustness both matter.
Lock Status Output for System Integration
Equipped with dry contact outputs (NO/NC), each unit can relay its locking status to access control panels, alarm systems, or building management platforms. This supports real-time monitoring, audit trails, and automated responses to access events or system anomalies.
