Product Description
Electromagnetic Locks
Schlage electromagnetic locks are used to secure the door in conjunction with push bars, request-to-exit devices, or credential readers for fail-safe applications when code compliance permits. You can use them on a single standalone door or as part of an access control system. Electromagnetic locks do not contain moving parts, making them extremely durable and preferred for high security applications. Electromagnetic locks consist of an armature and a coil assembly, which become magnetized when an electric current passes through them. This magnetic field secures the door. Electromagnetic locks are fail-safe by design. To unlock the door simply remove power.
Schlage offers a broad selection of electromagnetic locks – with a solution for most every application in every market. Whether it’s securing a hospital laboratory, monitoring a controlled area in an airport or providing traffic control for doors in a commercial or education building, Schlage electromagnetic locks provide breadth of application, depth of features and a proven record of performance, exceeding the standards set by the Builders Hardware Manufacturers Association (BHMA).
The M400 Series electromagnetic locks from Schlage are designed with the customer in mind to be robust, easy to install, and secure. The new bayonet mounting feature makes installs easier, allowing the installer to have their hands free during the mounting process. There is no need to consider door handing as all the M400 Series electromagnetic locks are both non-handed and symmetrical, allowing optimum placement of the magnet no matter the application.
The 40 and 70 Series is an integrator’s answer to retrofit needs for electromagnetics locks. These well-appointed electromagnetic locks are easy to stock, easy to select and easy to install. With common templating and standard features, the 40 and 70 Series Electromagnetic Locks for retrofit make sense for virtually every application.
The M390RFK is designed to retrofit the Locknetics 390+ without any additional prep. This ensures ease of installation for retrofit applications. The M390RFK comes standard with a door position switch (DPS), magnetic bond sensor (MBS), and relocking time delay (RTD).
Schlage offers electromagnetic locks for a variety of specialty applications including harsh exterior applications, mortised/vertical doors, gates and other smaller locking applications as well as delayed egress.
Designed with the customer in mind to be robust, easy to install, and secure.
