Magnetic Locks

Magnetic locks (maglocks) hold a door closed with a powerful electromagnet mounted to the frame and an armature plate mounted to the door. They release instantly on loss of power, making them the classic fail-safe solution for access control on doors that must drop open during alarm or power-loss events.

Plan Your Deployment

What to Look For

Maglocks are always fail-safe, so you must design free egress per local code, typically a motion-activated request-to-exit and a push-to-exit button. 1200 lbf is the standard for single commercial doors; double-door installations usually require a shear or a pair of surface-mount locks. Include a tie-in to the fire alarm relay for automatic release.

Common Deployment Scenarios

Maglocks are common on tenant entries, glass-door storefronts, data center doors, and interior security-zone doors. They are discouraged on primary egress stair doors in some jurisdictions; always verify local fire and life-safety code before specifying.
