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 M490 – Frequently Asked Questions

1) Will the Schlage M490 mag lock work on a fire-rated door?
The M490 is UL 10C listed for positive pressure fire tests of door assemblies at 3 hours, along with UL 1034 for burglary-resistant electronic locking mechanisms and UL 294 for access control. It also carries ANSI/BHMA A156.23 Grade 1, cUL and CSFM. That set is what a facility inspector will ask for on a fire door opening.
2) Does the M490 mag lock release when the power goes out?
Yes, and that is the point of it. The M490 is a fail-safe device, so it holds only while energized and drops the door free the moment power is cut. That is what lets it sit on an egress opening tied to a fire alarm or a request-to-exit device. If you need a door that stays locked without power, a mag lock is the wrong product family entirely.
3) What power supply do I need for a Schlage M490 mag lock?
Either 12 or 24 VDC will run it. The M490 has automatic voltage selection, so the lock detects the input and configures itself, no jumper or field setting to get wrong. Spec your power supply to whichever bus already feeds the rest of the access control at that opening.
4) What is the difference between the M490 and the M490P?
Sensing and reporting. The base M490 is the plain automatic-voltage-selection magnet: it holds the door and nothing more. The P version adds a magnetic bond sensor, a door position switch, and an adjustable relocking time delay, which is what an access control head end needs to report whether the door is actually closed and actually bonded. If the mag lock is being integrated with a system that monitors door status, order the P. If it is a standalone hold on a door with monitoring handled elsewhere, the base model is enough.
5) Can I use the M490 single door mag lock on a pair of doors?
Yes, with an optional bracket. Single door M400 models convert to double configurations using an optional mounting bracket. If you would rather order a purpose-built double, the M492 and M492P carry the same 1500 lb per leaf hold force. Mounting kits are also offered for top jamb mount and for HERCULITE brand glass doors.
6) What else do I need to order with a mag lock to make the door legal to exit?
The magnet is one piece of the system. An M400 Series mag lock is meant to run with push bars or request-to-exit devices and credential readers, plus a 12 or 24 VDC power supply, and it needs to release on fire alarm. Budget for the release hardware and the power at the same time as the lock. Mounting kits for top jamb, double door, and HERCULITE brand glass door applications are ordered separately, and the M490P can take an optional ATS/LED that combines an anti-tamper switch with reporting and a visual indicator of the magnetic bond at the lock.
7) What is the closest equivalent to a Schlage M490 mag lock from another manufacturer?
The Schlage M490 is a surface-mounted, fail-safe electromagnetic lock rated at 1500 lb holding force for a single door on 12/24VDC. The closest match by rating and configuration is the Dorma EML310, a single-door electromagnetic lock rated 1500 lb with an electrically locked (fail safe) function and a fire rating. The EML310 is ordered in two configurations: the EML310 DP 628 with a door position sensor, and the EML310 BA DP 628 which adds a bond alert to the door position sensor. That maps closely to how the M490 is ordered, where the base model runs automatic voltage selection and the P model adds a door position switch, magnetic bond sensor, and relocking time delay.
8) The egress plan calls for a delayed egress mag lock. Does the M490 cover that?
The M490 as built is a fail-safe magnet that releases when power drops, without a delay function. When the life safety plan calls for delayed egress on a single door, the comparable is the Alarm Controls 1200DE Series delayed egress magnetic lock for a single door. The DynaLock 2101 Series is a related but distinct part: a 1200 lb early warning lock, which signals on an attempted exit rather than holding the door for a timed delay.
9) Do I have to specify handing when ordering a Schlage M490 mag lock?
No. The M490 uses a symmetrical housing with field-selectable handing, so one part covers left and right hand openings and you sort it out at install. The bayonet mount also means you are not holding the magnet overhead while you fasten the bracket, and the armature pivot takes up slight imperfections in the opening so you still get a full bond on a door that is not perfectly true.
10) Should I use a mag lock or an electric strike on this door?
A mag lock like the M490 mounts on the surface at the head of the frame and needs no cutting into the frame or the door edge, which is why it goes in faster than an electric strike or an electric lock on an existing opening. The trade is that it is fail-safe by design and must be tied into egress hardware and the fire alarm. An electric strike lets you keep a mechanical latch and can be specified fail-secure. Retrofits on aluminum storefront and glass doors usually favor the magnet.
11) Is the Schlage M490 rated for heavy commercial traffic, or is it a residential lock?
Commercial, heavy duty, and hard wired. The M490 is a heavy duty commercial device with no battery, so it is not a standalone residential lock and will not function on its own without a 12 or 24 VDC supply. Grade 1 under ANSI/BHMA A156.23 is the top commercial tier for electromagnetic locks, which is what an institutional or MRO spec typically calls for.
12) Is a shear lock the same thing as an M490 magnetic lock?
No. The M490 is a surface-mounted electromagnetic lock, where the magnet body and the armature meet on the face of the door and frame. The ROFU 8031-002 is a shear lock rated 2200 lb on 12/24VDC with monitoring, and it works by engaging into the door edge so the hardware sits concealed at the top of the opening rather than on the surface. The higher holding number does not make it a drop-in for the M490; the preparation of the door and frame is different, and so is the way the door has to close for the lock to engage.
13) Our facility standard requires ANSI/BHMA Grade 1 and a UL listed magnet. Which of these mag locks meet it?
The Schlage M490 is certified to ANSI/BHMA A156.23, UL 1034, UL 294, UL 10C with a 3 hour fire rating, plus cUL and CSFM, which is the full stack a specification for a commercial heavy duty opening usually calls out. Among the comparable magnets, the Dorma EML310 and EML320 carry a fire rating and an electrically locked (fail safe) function, so they fit an opening where the fire rating drives the selection.
14) What finish does the Schlage M490 mag lock come in, and will it match my other door hardware?
One finish only: an aluminum housing in BHMA 628 satin. That is clear anodized aluminum, the standard companion to aluminum storefront and the most common finish on commercial door closers and exit hardware, so it lands cleanly on an aluminum or glass front opening. There is no dark bronze or black option on the M490, so if the rest of your openings are 613 or 622 the magnet will not match.
