ZKTeco DM-2805 Electromagnetic Door Lock
The ZKTeco DM-2805 Electromagnetic Door Lock is an electronic locking solution designed to secure doors in compatible access control installations. It uses electromagnetic force to hold the door closed while electrical power is supplied. When the access control system interrupts power, the magnetic holding force is released, allowing the door to open.
With a listed holding force of 280kg (600 lbs), the ZKTeco DM-2805 is suitable for various single-door access control applications. It can be integrated with compatible fingerprint terminals, face recognition devices, RFID card readers, exit buttons and access control panels.
How Does an Electromagnetic Door Lock Work?
An electromagnetic door lock uses an electromagnet mounted on the door frame and a matching metal armature plate attached to the door. When power is applied, the magnet attracts the plate and holds the door closed.
When the access control system interrupts power, the magnetic holding force is released. This is known as fail-safe operation: the lock unlocks when power is lost. Always plan the installation according to applicable fire safety requirements and emergency exit regulations.
280kg Magnetic Holding Force
The ZKTeco DM-2805 is listed with a holding force of approximately 280kg, equivalent to around 600 lbs. This rating describes the specified holding force under test conditions; actual security depends on correct installation, door construction, alignment and mounting hardware.
For the best results, ensure that the armature plate makes proper contact with the magnet and that the door frame can support the installation.
Compatible Access Control Systems
The DM-2805 can be used with compatible access control equipment, including:
- Fingerprint attendance and access control terminals
- Face recognition access control devices
- RFID card readers and access controllers
- No-touch exit buttons and push-to-exit switches
- Door access control panels
The lock, controller, power supply, exit button and wiring may be separate components. Confirm electrical compatibility before connecting the equipment.
Door Compatibility and Mounting
The DM-2805 is listed for use with wooden, metal, glass and fire-rated doors when the correct installation method and accessories are used.
Frameless glass doors may require a suitable U bracket, while other door types or opening arrangements may require an L or ZL bracket. Check the door design, frame dimensions and bracket requirements before ordering. Mounting brackets may be sold separately.
Applications of ZKTeco DM-2805
The ZKTeco DM-2805 may be suitable for:
- Office entrances
- Retail and commercial premises
- Educational institutions
- Business facilities
- Controlled-access rooms
- Other compatible single-door installations
For emergency exits, fire-rated doors or specialised security requirements, ensure the complete installation complies with applicable local regulations and the door manufacturer’s instructions.
