Geovision 81-ML1K2DS-0001 Electromagnetic Lock 1200LB
Overview
The Geovision GV-ML1200 (model 81-ML1K2DS-0001) is a 1200-pound electromagnetic lock engineered for door access control on commercial security installations. It converts electrical power into mechanical holding force—when energized, the electromagnet latches the armature plate to the door frame, locking the door until power is cut or an authorized unlock command is issued. This design eliminates moving parts and mechanical vulnerabilities, making it suitable for high-traffic entry points, secure perimeters, and integration with card readers, keypads, or badge systems.
Compatibility
The 81-ML1K2DS-0001 integrates with Geovision access control panels and third-party systems that output relay contacts or 12VDC control signals. Verify your controller's output capacity (typically 12VDC, 500mA or greater per lock) and relay contact ratings before installation. This lock works with standard door frames and strike plates; confirm frame geometry and material compatibility with your installation site before ordering.
Installation Notes
Operate at 12VDC with appropriate current capacity. The 1200LB holding force assumes proper installation—surface contact area, strike plate alignment, and door frame rigidity directly affect real-world performance. Electromagnets generate heat under sustained energization; ensure adequate ventilation around the lock body, especially in warm environments or high-unlock-cycle applications. Install the armature plate on the door, the magnet body on the frame, and route 12VDC and control wiring through conduit to the controller. Always include a manual override mechanism (mechanical key or mechanical release) to permit egress during power loss or system failure. Test lock/unlock function and verify holding force with a calibrated spring scale before commissioning.
