Features

• Strong Electromagnetic Holding Force of 280 kg (600 lbs)
  The DS-K4H258-U boasts a superior magnetic holding strength of up to 280 kilograms, offering solid resistance against forceful entry attempts. This level of holding force makes it an excellent fit for secure offices, data centers, R&D laboratories, and other high-security doors that require robust barrier protection without mechanical latches or keys.

• Fail-Safe Unlocking for Emergency Situations
  One of the key advantages of this lock is its fail-safe design: it unlocks automatically when the power supply is cut, ensuring safe egress during emergencies such as fires or electrical failures. This compliance with life-safety standards makes it an essential component in facilities where occupant safety must not be compromised by lock failure.

• Anodized Aluminum Housing with Anti-Tamper Properties
  Built with an anodized aluminum alloy casing, the DS-K4H258-U is engineered for durability and long-term indoor use. The corrosion-resistant finish and tamper-resistant structure provide protection in demanding environments, maintaining both aesthetics and performance even in heavily trafficked or restricted-access areas.

• Silent Operation with Zero Mechanical Wear
  Unlike traditional mechanical locks that include moving parts and generate noise or friction over time, this electromagnetic lock operates completely silently. The absence of physical interaction reduces mechanical degradation, resulting in low maintenance, no noise pollution, and a longer service life—ideal for hospitals, libraries, executive offices, and educational institutions.

• Real-Time Lock Status Signal Output (NO/NC)
  The built-in signal output for lock status monitoring ensures that security administrators can receive real-time alerts on whether the lock is engaged or released. This functionality integrates effortlessly with access control systems, allowing centralized management, instant status reporting, automated event logging, and enhanced system intelligence.

• Compatible with Multiple Door Types and Access Systems
  The DS-K4H258-U can be installed on wooden doors, glass doors, metal doors, and certified fireproof doors with appropriate mounting brackets. Its universal 12V DC compatibility ensures integration with a wide range of Hikvision and third-party access controllers, making it versatile for any single-door application.
