Hikvision DS-K4H258D Double-Door Electric Magnetic Lock – Sri Lanka Buying Guide

The Hikvision DS-K4H258D Double-Door Electric Magnetic Lock is a professional electromagnetic door-locking solution designed for commercial double-leaf access control installations in Sri Lanka.

Featuring two electromagnetic locking sections with a maximum holding force of 280 kg (617 lb) per section, the DS-K4H258D is suitable for businesses that need electronic locking for appropriately configured double-door entrances.

The lock supports 12V DC or 24V DC power, with a default 12V DC configuration. It also features a working-status LED, abrasion-resistant materials and a durable metal housing.

The DS-K4H258D can form part of a complete electronic door access control system when combined with a compatible Hikvision fingerprint terminal, face recognition terminal, MIFARE card reader or access controller.

Its double-door design makes it suitable for selected corporate offices, commercial buildings, hotels, factories, warehouses, educational institutions and other business premises.

Key Features & Benefits

How Does the Hikvision DS-K4H258D Work?

The Hikvision DS-K4H258D uses electromagnetic force to keep a suitable double-leaf door secured.

When the correct voltage is supplied, the two electromagnetic sections attract their corresponding metal armature plates attached to the door leaves.

When an authorized user authenticates through a compatible fingerprint, facial recognition, card or PIN access control system, the controller can interrupt power to the magnetic lock.

Once power is removed, the lock releases and the door can open.

This arrangement allows access control permissions to be administered through a separate compatible device.

Because electromagnetic locks rely on continuous electrical power to remain locked, professional system design is essential, especially for entrances requiring backup power or emergency exit facilities.

Recommended Business Applications

Corporate Offices

Secure double-leaf entrances at reception areas, administrative departments, staff-only floors and selected restricted offices.

A compatible biometric or RFID access control terminal can determine which employees are authorized to unlock the entrance.

Hotels & Hospitality Businesses

Provide electronic locking for suitable double-door entrances at staff departments, service areas and administration offices.

Factories & Manufacturing Facilities

Control designated double-leaf entrances serving production administration areas, staff sections and restricted facilities.

Warehouses & Distribution Centres

Secure suitable double-door entrances at logistics offices, restricted warehouse departments and internal commercial facilities.

Retail Stores & Commercial Showrooms

Provide electronic access locking for compatible double-glass or metal-framed entrances.

Educational Institutions

Support controlled access to selected administration departments, staff areas and restricted facilities.

Commercial Buildings

Use the DS-K4H258D as part of an integrated door access management system for suitable double-leaf entrances.

Important Factors Before Buying

• Double-Door Configuration: Confirm that both door leaves need electromagnetic locking and that the lock can be mounted correctly.
• Door Opening Angle: Hikvision describes an intended 90-degree door-opening application in its model datasheet.
• Door Opening Direction: Confirm whether the doors open inward or outward and select appropriate mounting brackets.
• Holding Force: The 280 kg × 2 specification represents two separate magnetic holding-force ratings, not a certified burglary-resistance rating.
• Doorframe Clearance: The mounting area must accommodate the 500 mm lock body and both armature plates.
• Power Supply: Choose a correctly rated regulated supply. At 12V DC, the manufacturer specifies 340 mA for each of the two locking sections.
• 24V Configuration: Although Hikvision advertises 24V DC support, confirm the actual device's terminal configuration and electrical rating before connecting a 24V supply.
• Mounting Brackets: A suitable double-door L/Z bracket may be needed. Bracket compatibility must be checked against the exact magnetic lock model.
• Glass Door Installation: Frameless glass doors may require specialized U-brackets or other manufacturer-approved mounting hardware.
• Emergency Egress: Electromagnetic locking systems must provide appropriate emergency escape and comply with applicable fire and building requirements.
• Power Failure: The DS-K4H258D is a fail-safe lock, meaning it releases when electrical power is removed.
• Backup Power: A compatible battery-backed supply may be required where appropriate, without compromising mandatory emergency release.
• Access Control Terminal: Fingerprint, face recognition, card and PIN authentication require a separate compatible controller or terminal.
• Exit Release Equipment: Appropriate exit buttons, emergency-release devices and other safety hardware may be needed separately.
• Installation Materials: Cabling, conduits, brackets, connectors, door sensors and electrical accessories are not automatically included.

Why Choose Hikvision DS-K4H258D?

The Hikvision DS-K4H258D provides a purpose-designed magnetic locking solution for compatible double-leaf doors.

Its main benefits are the 280 kg × 2 holding force, integrated double-door assembly, 12V/24V DC capability, working-status LED and durable metal construction.

Instead of treating a double-door entrance as two unrelated single-door installations, this model offers a unified magnetic lock body designed for two door leaves.

It is particularly useful when a business requires electronic door access through a compatible Hikvision biometric or RFID authentication system.

When installed with the appropriate bracket, regulated power supply, access controller and safety-release equipment, the DS-K4H258D can form part of a dependable commercial door access solution.
