Schlage Electronics M490 Magnetic Lock

Product Description

The SCHLAGE ELECTRONICS M490 is a single maximum security magnetic lock designed for access control applications in commercial, institutional, and high-security environments. It mounts to a door frame and holds the door closed through electromagnetic force, releasing when an authorized signal is received. Licensed electricians and security integrators are the primary installers. The M490 measures 13.6 inches in length, 4.4 inches in width, and 3.4 inches in height, making it suited for standard commercial door frames where a flush or surface-mount installation is required.

The M490 is intended for single-door access control installations in commercial buildings, institutional facilities, and secured entry points. It fits applications where high holding force and reliable fail-safe operation are required. The surface-mount form factor makes it adaptable to both new construction and retrofit projects on inswing or outswing door assemblies with appropriate brackets.

Installation Notes

Installation should be performed by a licensed electrician or credentialed security integrator familiar with low-voltage access control wiring and local electrical codes. Disconnect all power to the access control circuit before mounting or wiring the lock. Follow applicable NEC guidelines for low-voltage wiring runs and ensure the door frame and armature plate are properly aligned to achieve rated holding force. Do not energize the lock until all wiring connections are verified and the armature plate is fully seated.
