Understand what an electromagnetic lock does

An electromagnetic lock develops holding force while powered and releases when its power is removed. It does not pull a poorly closing door into alignment and it does not provide a mechanical latch. Reliable operation depends on full armature contact, rigid mounting, correct voltage and a door that returns consistently to the closed position.

Use a magnetic lock only where the release strategy is appropriate

Maglocks may be considered on selected glass, aluminium or other openings where purpose-designed mechanical locking is impractical. Their power-to-lock nature makes exit, emergency release, fire interfaces and power supervision central to the design. A convenient mounting location is not sufficient justification.

Compare the maglock with an electric strike, electrified mortice lock or other suitable hardware. Consider security on loss of power, forced-entry resistance, appearance, door loading and whether the building can support the required release arrangements.

Diagnose holding problems at the door

• Partial armature contact caused by door sag, closer drift or a rigidly mounted armature.
• Incorrect supply voltage, excessive cable drop or undersized power equipment.
• Residual magnetism or binding that delays release.
• Release devices wired through an inappropriate or undocumented path.
• A door-position sensor that reports closed even when the armature has not seated.

Test every release path independently

Verify authorised entry, free/approved exit, request-to-exit operation, emergency release, power loss, fire interface where required, door-held events and restoration. Confirm that no software, network or controller fault can defeat a required direct release path.

Label supplies and release equipment, record the wiring cause and effect, and train the site on faults that require immediate service rather than repeated reset.
