## Long description

DAHUA DHI-ASF280A-V1 is an electromagnetic door lock engineered for integration with access control systems. Designed to operate at 12 V with a current draw of 510 mA, this electromagnet delivers reliable holding performance across ambient temperatures from -20 to 55 °C. The magnet assembly measures 25 cm × 4.86 cm × 2.6 cm and is intended for securing interior and exterior doors where controlled entry is required.
Advantages
The device is constructed from aluminum alloy with surface oxidation treatment for enhanced durability in indoor and sheltered outdoor environments. Built-in reverse current protection and anti-residual magnetism design reduce fault risk and improve operational consistency. The lock includes LED status indication and supports door detector signal feedback through a five-wire connection. It is tested for long service life, withstanding up to 40,000 power-on cycles during aging tests, and relies solely on electromagnetic force, eliminating mechanical wear points. Automatic unlocking occurs when power is removed.
Suitable for
Access control on office and commercial interior doors
Entrances with glass, wood, metal or fireproof doors
Integration with Dahua and other mainstream access control systems
Locations requiring visible status indication and door position feedback

How to use
Mount the electromagnet on the door frame and align the armature plate on the door leaf to ensure full face contact when closed. Connect the five-wire harness according to the access control system wiring diagram: power (12 V and ground), LED status output, and door detector feedback lines. Ensure reverse current protection wiring and grounding follow the installer manual. After wiring, apply power and verify LED indication, magnetic holding, and door detector feedback. Adjust the position of the armature plate if necessary to obtain a secure and even contact surface.
Usage recommendations
For reliable long-term operation, install the electromagnet in a protected location away from direct exposure to heavy weather. Regularly inspect the mounting hardware and armature contact surface for debris or corrosion and clean as needed. Use appropriate power supply with stable 12 V output and sufficient current capacity (at least 510 mA plus margin for control circuitry). When integrating with access control panels, follow manufacturer wiring diagrams and test fail-safe behavior during routine maintenance.
