## Summary description

The Hikvision DS-K4H250D is an electromagnetic lock with a holding force of 272 kg, designed for secure access control. It operates on an input voltage of 12-24 V and consumes 500 mA at 12 V. The compact dimensions make it suitable for various installations.

## Long description

The Hikvision DS-K4H250D electromagnetic lock is a compact, white access control device with a holding force of 272 kg and an input voltage range of 12–24 V. Designed for installation on wooden, glass and steel doors with a 90° opening angle, the unit is intended to secure single-leaf doors in commercial and residential settings. Current consumption is 500 mA at 12 V, and the lock includes door status indication and an output for lock status monitoring to integrate with access control systems.
Advantages
The lock combines a relatively high holding force with compact dimensions, making it suitable for varied installations where space is limited. Its wide input voltage range (12–24 V) allows compatibility with common access control power supplies, while the door status indicator and lock status signal output simplify system integration and monitoring.
Suitable for
 Securing wooden doors in offices and homes
 Mounting on glass doors with appropriate hardware
 Use on steel doors for interior access control
 Integration with access control panels and alarm systems
 Applications requiring a holding force around 272 kg
When it may not be suitable
The DS-K4H250D is intended for doors with a maximum opening angle of 90°; it may not be suitable for sliding doors, double-leaf doors without appropriate adapters, or doors that require a wider swing. It is not designed as a standalone mechanical locking cylinder and depends on continuous power for magnetic holding, so it will release in a power loss unless paired with an appropriate fail-secure or backup power solution.
Key specifications
 Holding force: 272 kg (approximately 599.8 lbs)
 Input voltage: 12–24 V DC
 Current consumption: 500 mA at 12 V
 Color/finish: White
 Suitable door types: wooden, glass, steel (90° opening)
 Door status indicator: yes
 Signal output: lock status/door status output for monitoring
 Mounting: surface mount (requires appropriate brackets for glass or special frames)
How to use
Mount the electromagnetic lock on the door frame and the armature plate on the door leaf using the manufacturer-recommended brackets and fasteners. For glass doors, use dedicated glass-door mounting hardware. Connect the power supply within the specified 12–24 V DC range and observe polarity. Integrate the lock status output to the access control panel or monitoring system for remote status reporting. Test the door status indicator and signal outputs after installation to confirm correct wiring and operation. Ensure wiring is routed to avoid pinch points and that the armature plate aligns flat against the magnet face for full holding force.
What to consider before purchase
 Verify door type and opening angle (suitable for doors with up to 90° opening)
 Confirm available access control power supply can provide 12–24 V DC and sufficient current (500 mA at 12 V)
 Check mounting requirements and whether glass-door or special brackets are needed
 Plan for backup power or fail-secure arrangements if holding during power loss is required
Usage recommendations
Use the Hikvision DS-K4H250D with a compatible access control panel and reliable 12–24 V DC power source. For glass doors, use the correct mounting kit to ensure secure attachment and optimal magnetic contact. Periodically inspect the armature plate and magnet face for debris or misalignment to maintain maximum holding force and reliable door status reporting.
