## Long description

Hikvision DS-K4H250S is a surface-mounted electromagnetic lock designed to secure single doors where a reliable magnetic holding mechanism is required. The unit provides a holding force of 300 kg and supports 12–24 VDC operation. With compact electromagnet dimensions and built-in protection components, the lock is intended for use on wooden, glass, metal and fire-resistant doors in access control installations for both interior and exterior applications.
Advantages
The DS-K4H250S delivers consistent holding performance up to 300 kg while allowing flexible supply voltage selection between 12 V and 24 V. Integrated surge protection (MOV) and a door lock status signal output facilitate compatibility with access controllers and alarm systems. Its surface-mounted design simplifies installation on a range of door types without the need for complex frame modifications. Low-profile dimensions and a white finish make the unit unobtrusive in most environments.
Suitable for
 Access control on interior office and residential doors
 External entry points with covered installations
 Wooden, glass, metal and fire-resistant door applications
 Integration with access control panels and alarm systems requiring lock status feedback
Key specifications

 Supply voltage: selectable 12 VDC (default) or 24 VDC
 Power consumption: 500 mA at 12 V
 Built-in surge protection: MOV (voltage dependent resistor)
 Door lock status output: NONC/COM signal for integration with controllers
 Electromagnet dimensions: width 240 mm, depth 49 mm, height 25.5 mm
 Finish colour: white; surface-mounted design suitable for various door materials
How to use
Mount the electromagnetic lock on the door frame surface and align the armature plate to the corresponding position on the door leaf. Connect the power supply using the appropriate 12 V or 24 V DC input, observing polarity and power requirements; at 12 V the unit draws approximately 500 mA. Wire the door lock status output to the access controller or alarm input as required. After mechanical installation and electrical connection, test the lock engagement and release with the access control system and adjust the armature plate alignment to ensure full contact for optimal holding force.
Usage recommendations
Use a regulated DC power supply sized to handle the lock’s current draw plus any connected control electronics. For external installations expose the unit to limited weather or use appropriate weatherproof housings. Verify compatibility with the door frame and ensure the armature plate is fitted on a flat surface to achieve the specified holding force; periodic inspection of mounting hardware and electrical connections is recommended to maintain reliable operation.
