Ubiquiti UA-LOCK-MAGNETIC-540KG Fail-safe magnetic lock

Ubiquiti UA-LOCK-MAGNETIC-540KG Fail-Safe Magnetic Lock

Overview

The Ubiquiti UA-LOCK-MAGNETIC-540KG is a fail-safe magnetic lock designed for integration with UniFi Access control systems. This electromagnetic locking mechanism provides 540 kg (approximately 1,190 lbs) of holding force, making it suitable for securing standard entry doors in commercial and institutional environments. The unit weighs 13.5 lbs and is manufactured to Ubiquiti's specifications for reliable operation across diverse deployment scenarios.

Key Features

The magnetic lock form factor delivers holding force without mechanical bolts or pins, reducing wear and maintenance compared to traditional strike mechanisms. Fail-safe operation means the lock releases power upon loss of electricity, allowing egress during power outages—a critical safety feature in access control deployments. Management through the UniFi Access Hub integrates the lock into a centralized control ecosystem, allowing remote monitoring and audit logging alongside credential verification. As part of the broader UniFi Accessories product family, the UA-LOCK-MAGNETIC-540KG aligns with standard Ubiquiti UniFi deployment practices and documentation.

Deployment Scenarios

This magnetic lock is appropriate for office entry doors, laboratory access points, server room entries, and other applications where electromagnetic holding force meets security requirements without imposing heavy mechanical infrastructure. The 540 kg holding capacity accommodates standard single-leaf doors and lighter double-leaf configurations. Organizations implementing multi-site UniFi Access deployments can standardize on this lock across facilities, simplifying procurement, spare parts management, and technician training.

Network Integration

The UA-LOCK-MAGNETIC-540KG connects to the UniFi Access Hub, which serves as the control and decision point for access grants and lock states. Integration with UniFi's authentication and authorization ecosystem allows credential validation to trigger unlock commands. The hub logs all lock events, providing audit trails for compliance and incident investigation. Network connectivity for the hub itself follows standard UniFi architecture—wired Ethernet or PoE where available.

Installation Notes

Magnetic locks require proper door frame alignment and sufficient mounting surface to distribute holding force. The 13.5 lb unit should be mounted at the top of the door frame or header, with the armature plate positioned on the door itself. Power delivery to the Ubiquiti UA-LOCK-MAGNETIC-540KG typically comes through the UniFi Access Hub control circuit; verify power budget and circuit capacity during design. Fail-safe wiring ensures the lock de-energizes during power loss, prioritizing emergency egress.

Marty Allison, Infrastructure Architect

"The UA-LOCK-MAGNETIC-540KG brings electromagnetic simplicity to UniFi Access deployments. At 540 kg holding force, it covers most office and institutional door types without overspecification. The fail-safe design is non-negotiable for life safety—power loss unlocks rather than traps occupants. If you're running UniFi Access across multiple sites, standardizing on this lock keeps spares inventory lean and training overhead low."
