SCHLAGE M400 SERIES OVERVIEW

M400 Series electromagnetic locks or “mag locks” are used as part of an electronic security solution usually combined with push bars, request-to-exit devices and credential readers. They are an easy-to-install alternative to electric strike or electric lock products with a bayonet mounting design that eliminates the need to hold the lock overhead while securing.

M400 Series models are designed specifically with the customer in mind to be robust and easy to configure. Sixteen models cover a full range of needs with 500, 1000, 1300 and 1500 lb. hold force options in single and double configurations, with and without delayed egress. The additional "Plus" models in all configurations add intelligent sensing and reporting features needed for integration with access control systems.

All Schlage electromagnetic locks come with a limited lifetime warranty on the magnetic coil assembly for added confidence in the longevity of these robust products.

Schlage Electronics M490DE – Frequently Asked Questions

1) Is the Schlage M490DE mag lock delayed egress, and how long is the delay?
Delayed egress, yes. The M490DE is factory configured with a 30-second delay, and the Plus version is also orderable in a BOCA compliant 15-second delay. Delayed egress models include a plunger switch and external switch input, an authorized release input, an on-board audible alarm with bi-color LED, and fire alarm terminals. On the certification side, the delayed egress models carry UL special locking arrangements, meet NFPA 101 life safety code, and are built to ANSI/BHMA A156.24.
2) Will the M490DE mag lock unlock if the building loses power?
Yes. The M490DE is a fail-safe device, so cutting power releases the magnet and the door opens. That is how mag locks are required to behave on an egress opening, and it also means the lock needs a supervised power supply and a fire alarm tie-in to do its job, not a battery. There is no battery backup in the lock itself.
3) What is the difference between the M490DE and the M490DEP?
The P adds the monitoring your access control system wants: magnetic bond sensor (MBS) to confirm the magnet actually made bond, door position switch (DPS) to report open or closed, and an adjustable relocking time delay (RTD). The plain M490DE gives you the delayed egress lock with automatic voltage selection and no reporting outputs. If the mag lock is being integrated into a head-end that needs door status, order the P. There is also an optional ATS/LED that combines an anti-tamper switch with a bond status indicator at the lock.
4) Does the M490DE handing have to be specified when ordering?
No handing to specify. The housing is symmetrical and handing is selected in the field, so the same lock works left or right. Installation is a bayonet mount, which means you fasten the mounting bracket first and then hook the magnet onto it instead of holding the lock overhead while you drive screws. The armature mount also pivots to take up slight imperfections in the opening so you still get a full bond on a door that isn't perfectly true.
5) Can I use the Schlage M490DE on a pair of doors or on a glass storefront door?
Out of the box it's a single door, surface mounted lock. Single door models convert to double with the optional bracket, and Schlage lists optional mounting kits for top jamb mount, double door, and HERCULITE brand glass doors. For a factory double-leaf delayed egress build instead, the M490DE-2 and M490DEP-2 cover 1300 lb per leaf.
6) Is the Schlage M490DE fire rated and what standards does it meet?
UL 10C listed for positive pressure fire tests of door assemblies at 3 hours, plus UL 1034 for burglary-resistant electronic locking mechanisms, UL 294 for access control systems, ANSI/BHMA A156.23 Grade 1, cUL and CSFM. For an institutional spec sheet that is the full list carried on the M400 Series mag lock, and the delayed egress build adds ANSI/BHMA A156.24 and NFPA 101 compliance.
7) What is the difference between the Schlage M490DE and the Alarm Controls 1200DE delayed egress mag lock?
Both are delayed egress magnetic locks for a single door. The Schlage M490DE is rated at 1300 lbs holding force, runs on auto-selected 12/24VDC, and carries UL 10C 3 hour fire rating plus UL 294 access control listing, with an aluminum housing surface mounted on the door. The Alarm Controls 1200DE is that maker's delayed egress single door magnetic lock in the 1200DE Series. If you are standardizing on a delayed egress single door opening and need the 1300 lb force class with 12/24VDC auto voltage selection, the M490DE is the direct pick.
8) Is a shear lock like the ROFU 8031-002 a substitute for the M490DE?
It is a different locking method, not a drop-in alternate. The ROFU 8031-002 is a shear lock rated 2200 LB holding force at 12/24VDC and monitored, and shear locks mortise into the door and frame rather than mounting on the surface. The Schlage M490DE is a surface mounted electromagnetic lock at 1300 lbs holding force with delayed egress, so it goes onto an existing opening without cutting the door and frame for a mortised body. Choose the M490DE where the opening cannot be prepped and delayed egress is required; the shear lock suits openings where a concealed installation is wanted and the frame can be machined.
9) What is the closest 1500 lb alternative to the Schlage M490DE for a single door?
The Dorma EML310 is a single door electromagnetic lock rated 1500 lb with electrically locked fail safe function and a fire rating. It comes in a door position sensor version, EML310 DP 628, and a version that adds bond alert, EML310 BA DP 628 - the bond alert model is the one to match against a Schlage Plus configuration, since the Plus variant of the M490DE adds a door position switch, magnetic bond sensor and relocking time delay. The M490DE itself is 1300 lbs holding force and fail-safe, and it is the model that carries delayed egress; the EML310 does not.
10) Which mag lock should I standardize on for a fire rated opening across a facility?
The Schlage M490DE carries UL 10C 3 hour fire rating and UL 294 access control listing, along with UL 1034, ANSI/BHMA A156.23, cUL and CSFM, and it is fail-safe so the magnet releases on loss of power. The Dorma EML310 single door and EML320 double door units are also fire rated and electrically locked fail safe, which makes them the pair to consider if you are standardizing single and double openings on one brand. Match the certification list to what your facility's authority having jurisdiction requires before locking in a standard.
11) What voltage does the Schlage M490DE run on, do I have to set a jumper?
12 or 24 VDC, and you do not set anything. Automatic voltage selection means the lock reads the input and configures itself, so one part number covers both power supply types. Useful when you are standardizing a building and don't want two SKUs on the truck.
12) Is a mag lock like the M490DE better than an electric strike for my access control door?
A mag lock is the easier retrofit. There is no mortising into the door or frame the way an electric strike or electrified lock requires; the M490DE surface mounts with a bayonet bracket at the head. The trade is that it holds only while powered, so it is fail-safe by design and needs a request-to-exit device, push bar, or credential reader wired with it as a complete system, plus fire alarm release. If you need the door to stay latched with the power off, a mag lock is the wrong choice and an electric strike or electrified lockset is what you want.
13) The door swings in - can I still use the M490DE or do I need a different magnet?
A surface mounted magnet like the Schlage M490DE mounts on the frame with the armature on the door, and the M400 Series offers optional mounting kits for top jamb mount, double door and HERCULITE brand glass doors to suit the opening. Where a single magnet needs to cover either swing direction from stock, the DynaLock 2050 Series is a 1200 Lb single electromagnetic lock surface mounted for outswing or inswing on single or double doors, and the DynaLock 2011 is specifically an outswing single door lock at 1200LB. Confirm the swing before ordering brackets.
14) Is the ROFU 8512 the same kind of lock as the Schlage M490DE?
Both are magnetic locks running on 12/24VDC, but they differ in mounting and function. The ROFU 8512 is a standard single magnet with selectable keyhole mount rated 1200 LB holding force at 12/24VDC. The Schlage M490DE is a 1300 lbs holding force single door magnet with automatic voltage selection for 12 and 24 VDC and a bayonet mounting design, and it is a delayed egress model factory configured with a 30-second delay. If the opening requires the timed egress delay, the 8512 will not cover it.
15) What finish and material is the Schlage M400 Series mag lock housing?
Aluminum housing in BHMA 628 satin finish, which is the standard clear anodized aluminum look that matches most commercial aluminum storefront and door frames. It is a heavy duty commercial device, not a residential one, so expect it to sit visibly on the frame face rather than hide in the opening.
