Hikvision Single-Door Magnetic Lock DS-K4H250S(O-STD)

DS-K4H250S Single-Door Magnetic Lock

The DS-K4H250S is an electromagnetic locking system designed for access control applications. This magnetic lock offers powerful security through electromagnetic force rather than mechanical components. It provides reliable door control for various door types with precise monitoring capabilities.

Robust Security Performance

The DS-K4H250S delivers impressive holding power with its 280 kg (617 Lbs) static linear thrust. This substantial force ensures doors remain securely locked when activated. Additionally, the lock features an anti-residual magnetism design that prevents lingering magnetic effects after power is removed.

The lock incorporates:

• Internal voltage dependent resistor (MOV) for surge protection
• Abrasion-proof materials for extended durability
• Aldural shell with hard anodizing electroplating for corrosion resistance
• Electromagnetic operation with no mechanical failure points

Versatile Installation Options

The DS-K4H250S accommodates multiple door configurations:

• Wooden doors
• Glass doors
• Metal doors
• Fireproof doors

This versatility makes the DS-K4H250S appropriate for various architectural settings. The lock is designed for doors with a 90° opening angle, ensuring functionality while maintaining security standards.

Advanced Monitoring Features

The DS-K4H250S provides comprehensive status monitoring through:

• LED indicator displaying door lock status (Red: Unlocked, Green: Locked)
• Signal output of door lock status using dry contact signals (NO/NC/COM)
• Support for maximum power rate of 3A

These monitoring capabilities allow integration with broader security systems. The DS-K4H250S can transmit lock status information, enhancing overall access control management.

Flexible Power Configuration

The DS-K4H250S offers adjustable power options:

• Customizable power supply: 12 VDC or 24 VDC
• Default voltage: 12 VDC
• Working current: 12 V/500 mA or 24 V/250 mA

Power selection is easily configured via jumper settings on the circuit board. This adaptability allows the DS-K4H250S to integrate with existing power infrastructure.

Ideal Applications

The DS-K4H250S is particularly suitable for:

• Commercial buildings requiring monitored access control – the 280 kg holding force provides substantial security for sensitive areas
• Multi-door security systems – the status monitoring capabilities enable centralized management
• Facilities with varying door types – the versatile installation options accommodate diverse architectural needs
• Environments requiring reliable operation – the electromagnetic design eliminates mechanical failure points
