HIKVISION DOUBLE-DOOR MAGNETIC LOCK – DS-K4H450D(O-STD) - Powerful Dual-Leaf Electromagnetic Lock for High-Security Access Control

The Hikvision DS-K4H450D(O-STD) Double-Door Magnetic Lock is a high-performance electromagnetic locking device designed specifically for securing dual-leaf doors in high-traffic commercial, institutional, and industrial facilities. Built to provide maximum holding force and silent operation, this lock delivers advanced security performance while allowing seamless integration with Hikvision’s comprehensive access control systems. Whether used in secure corridors, lobbies, server rooms, public access buildings, or interlocking door systems, this dual-magnet solution ensures both doors are firmly secured without mechanical wear or compromise.

Crafted from rugged, anti-rust aluminum alloy and equipped with dual 280 kg (600 lb) holding force magnets—one for each door leaf—this lock offers a total combined resistance of up to 560 kg. The DS-K4H450D(O-STD) is the professional’s choice for installations that demand high strength, durability, quiet operation, and fail-safe control in double-door configurations. Its status signal output provides real-time monitoring capabilities, making it ideal for facilities where visibility, remote supervision, and incident logging are critical.

Features

• High-Strength Dual Electromagnetic Holding Force
  The DS-K4H450D(O-STD) features two individual magnetic locks, each capable of providing up to 280 kg of holding force, for a total resistance of 560 kg across a double-door setup. This allows the lock to secure both door leaves independently but simultaneously, ensuring consistent locking even under external force or frequent usage. The electromagnetic plates use advanced coil design for improved conductivity and locking reliability, offering enhanced resilience in both standard and sensitive security areas.

• Fail-Safe Operation for Life Safety Compliance
  As a fail-safe locking mechanism, the DS-K4H450D(O-STD) automatically releases both doors in the event of a power outage or emergency situation. This design is essential in buildings where emergency egress is required under life safety codes and fire regulations. The lock can be easily integrated with fire alarm panels, emergency exit buttons, or backup power systems, allowing for intelligent unlocking in response to system triggers or power failure conditions.

• Silent and Smooth Locking Mechanism
  With no moving mechanical parts, the electromagnetic locking system ensures completely silent operation. This makes the lock suitable for offices, banks, hospitals, and executive facilities where a quiet, undetectable security solution is preferred. The locking and unlocking processes are instant and seamless, eliminating mechanical wear and extending the device’s operational life without maintenance-intensive components.

• Durable Aluminum Alloy Housing for Long-Term Use
  The lock’s outer casing is constructed from anodized aluminum alloy, offering excellent resistance to corrosion, moisture, and tampering. This makes it highly reliable in both interior and semi-controlled environments such as building lobbies, commercial complexes, and high-traffic public spaces. The lock body and armature plates are precision-machined to ensure solid contact between magnet and plate for consistent operation.

• Real-Time Status Output Monitoring
  The DS-K4H450D(O-STD) is equipped with status signal output terminals that allow integration with alarm systems, access controllers, or centralized monitoring software. Security personnel or building automation systems can receive feedback on the door lock state—engaged or disengaged—enabling event-triggered actions such as video recording, alert generation, or access event logging. This function ensures intelligent visibility into every lock interaction, boosting facility awareness and safety.
