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-2 – Frequently Asked Questions

1) Will the Schlage M490DE-2 mag lock work on a pair of doors, or do I need two separate locks?
The M490DE-2 is the double door configuration, so one unit covers both leaves at 1300 lb per leaf holding force. You do not order two singles. If your opening is a single door, the equivalent delayed egress model is the M490DE. Note the M400 single door models also convert to double with an optional bracket, so a single already in the field can be adapted rather than replaced.
2) Does the Schlage M490DE-2 have delayed egress, and how long is the delay?
Delayed egress is built in, and it ships factory configured at a 30 second delay. That is what the DE in the model number means. The delayed egress side brings a plunger switch plus an external switch input, an authorized release input, an on-board audible alarm with bi-color LED, and fire alarm terminals so the lock drops on an alarm signal. Delayed egress models meet NFPA 101 life safety code and carry ANSI/BHMA 156.24 and UL special locking arrangements. If your authority having jurisdiction requires a 15 second BOCA compliant delay, that is orderable on the Plus model.
3) What happens to the M490DE-2 mag lock when the power goes out?
It unlocks. The M490DE-2 is fail-safe, which is inherent to an electromagnet: no current, no bond, doors free. That is why mag locks always need a code compliant egress path and why the fire alarm terminals on the delayed egress board matter. If your application requires the door to stay locked during a power loss, a mag lock is the wrong product family and you want a fail-secure electric strike or electrified lock instead.
4) Can the M490DE-2 go on a fire rated door assembly?
Yes. It is UL 10C listed for positive pressure fire tests of door assemblies to 3 hours, and it also carries UL 1034 for burglary-resistant electronic locking mechanisms, UL 294 for access control, ANSI/BHMA A156.23 Grade 1, cUL and CSFM. The delayed egress version additionally holds UL special locking arrangements and ANSI/BHMA 156.24, and meets NFPA 101. That combination is what an institutional specifier usually needs to see on a monitored egress opening.
5) What is the difference between the two M490DE-2 models when I order?
Two choices. The base model gives you automatic voltage selection and the delayed egress board. The P (Plus) model adds a magnetic bond sensor, an adjustable relocking time delay, and a door position switch, which is what an access control head end needs to actually report door state and confirm the magnet has bonded. If the lock is tying into a card access system that monitors openings, take the Plus. If it is standalone, the base model does the job. An anti-tamper switch with LED bond indication at the lock is an option on Plus models.
6) Can a Schlage M490DE-2 mag lock be used on a glass storefront or Herculite door?
Yes, with the right bracket. Optional mounting kits are available for top jamb mount, double door, and HERCULITE brand glass doors. The lock itself is a surface mounted unit in an aluminum housing with a 628 satin finish, which is the standard match for aluminum storefront framing. The bracket is a separate order line, so specify the glass door kit up front rather than discovering it on site.
7) Can I install a mag lock like the M490DE-2 outdoors or in an unheated space?
Only within 0 to 49 degrees C (32 to 120 degrees F). That rules out unheated exterior gates in a cold climate and any opening that freezes. For a weather exposed opening, ZenSupply carries purpose-built weather resistant magnetic locks: the Alarm Controls 1200WP Series, the Locknetics WMG Series, and the Dortronics 1000 Series, which is sealed and weather resistant. Those are single door units, so a pair outdoors takes two.
8) What else do I need to buy to make the M490DE-2 a working access control opening?
The lock is one piece of the system. A mag lock is normally combined with push bars, request-to-exit devices and credential readers, plus a 12 or 24 VDC power supply, since the lock has no battery. Add the mounting kit that matches your opening (top jamb, double door, or HERCULITE glass door) if the standard mount does not suit. If the system needs to report door status back to the head end, order the P model so you get the door position switch and magnetic bond sensor rather than adding sensing later.
9) My opening is a single leaf but I want the same delayed egress behavior as the M490DE-2. What should I order?
The M490DE-2 is the double door configuration, rated 1300 lb per leaf, with a factory configured 30-second delay. For a single leaf with delayed egress, the Alarm Controls 1200DE Series is a delayed egress magnetic lock for single doors. The DynaLock 2101 Series is an early warning lock at 1200 lb, which sounds on an attempted exit rather than being a plain hold. Confirm with the authority having jurisdiction which of these the occupancy calls for, since delayed egress and early warning are treated differently in a life safety review.
10) Which mag lock should I standardize on across a facility if I need a fail-safe lock on a fire rated opening?
The Schlage M490DE-2 is fail-safe and carries UL 10C with a 3 hour fire rating along with UL 294 for access control, ANSI/BHMA A156.23, UL 1034, cUL and CSFM. Among the alternatives, the Dorma EML310 BA DP, EML310 DP and EML320 are all listed as fire rated with an electrically locked fail safe function, with the EML320 being the double door version at 1500 lb. Standardizing across a facility usually means one manufacturer for the mag locks and one for the release devices, so pick the family that covers both your single leaf and double leaf openings before you commit the first order.
11) What voltage does the Schlage M490DE-2 need, and do I have to set it?
12 or 24 VDC, and you do not set anything. Automatic voltage selection detects the input, so the same lock drops onto either supply without a jumper or a switch. It is a hardwired device, not battery powered, so it needs a dedicated DC supply and, because it is fail-safe, that supply should be backed up if you want the opening secure through an outage.
12) Do I have to specify handing when I order the M490DE-2?
No handing to call out. The housing is symmetrical and handing is field selectable, so the same lock works on either leaf and you set it during install. The bayonet mount also means you are not holding the magnet overhead while you fasten the bracket, and the armature mount pivots to take up slight misalignment in the opening, which is what usually costs you bond strength on an older frame.
13) I only need delayed egress on one door, not a pair. What should I order instead?
On a single leaf, the M490DE is the single door version of the same 1300 lb delayed egress lock. From another brand, the Alarm Controls 1200DE Series is a delayed egress magnetic lock for a single door. The M490DE-2 is built specifically for the double door opening, so putting it on a single leaf leaves you paying for hardware you cannot use.
14) Is a mag lock like the M490DE-2 the right choice, or should I use an electric strike or a shear lock?
A mag lock is the fast retrofit. It surface mounts to the frame with no door or frame prep and no cutting, which is why it goes in where an electric strike would mean machining the jamb. The tradeoff is that it is fail-safe and always visible on the header. A shear lock, such as the ROFU 8031-002 at 2200 lb monitored holding force on 12/24 VDC, mounts concealed in the header if you want the hardware out of sight. An electric strike or electrified lock is the choice when the opening has to remain locked with the power off.
15) I need a mag lock with door position and bond monitoring for an access control head end. How do the options compare to the Schlage M490DE-2?
The M490DE-2 comes in a base automatic voltage selection model and a P model that adds a door position switch (DPS), magnetic bond sensor (MBS) and relocking time delay (RTD). Comparable monitored units include the Dorma EML310 BA DP, a single door 1500 lb lock with bond alert and door position sensor, the Dorma EML310 DP, the same single door 1500 lb lock with door position sensor only, the Locknetics MG Series available in monitored form, and the ROFU 8031-002, a monitored shear lock. The Dorma pair is the clearest read on the difference: bond alert plus position on one, position only on the other.
16) Will the M490DE-2 match the finish on my other aluminum storefront hardware?
The housing is aluminum in BHMA 628 satin finish, the standard clear anodized aluminum look used across commercial storefront and door hardware, so it lines up with 628 exit devices, closers and frames already on the building. There is a single finish on this model, so there is nothing to choose at order time.
