Schlage Electromagnetic Locks Maximum Security Delayed Egress on Magnatic Coil Assembly Series Double Lock Separate Housing - M492DE
Product Description
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.
Maximum Security
Schlage M490/M492, M490P/M492P and M390RFK magnetic locks are designed with 1500 lbs. of holding force for maximum security applications.
Specialty Applications
M490G, M490DE/M490DE-2, M490DEP/M490DEP-2, 320M and GF3000 Mortise Shear/Surface Shear magnetic locks offer unique capabilities for use in a variety of specialty applications such as outdoor gates, delayed egress, sliding doors and concealed mounting.
Schlage M490DE/M490DE-2
Designed with the customer in mind to be robust, easy to install, and secure.
Schlage M490 Series maximum security delayed egress electromagnetic locks are designed to meet the NFPA 101 Life Safety Code. They provide the same robust, easy to install security of the M400 Series locks. All four M490 delayed egress models feature 15-second delayed egress timer with audible alarm that can be triggered by an internal “plunger switch,” or by external contacts, such as a request-to-exit push bar. ""Plus"" models with P designation add intelligent sensing and reporting features needed to integrate with access control systems.
The Schlage M490DE delayed egress electromagnetic lock is designed to meet NFPA 101 Life Safety Code while providing the same robust, easy-to-install, security of our M400 Series magnetic locks. The M490DE has a 15-second delayed egress timer with audible alarm which can be configured to trigger by an internal “plunger switch,” or by external contacts, such as a request-to-exit push bar.
All M400 Series electromagnetic locks are symmetrical with field-selectable handing, allowing optimum placement of the magnet no matter the application. They are designed to provide automatic voltage sensing for 12 and 24 volts along with polarity protection to make wiring less complex. M490DE models are tested and certified to meet or exceed UL special locking arrangements and BHMA 1500 lb hold force requirements.
M490DE electromagnetic locks come in four configurations to meet your specific security needs. Single and double door models are offered in standard configurations. Plus versions of these models with “P” designations add intelligent sensing and reporting features needed to integrate with access control systems.
This easy-to-install, cost effective solution provides maximum access security and safety.
