Schlage Electronics 320M 628 – Frequently Asked Questions

1) Will the Schlage 320M work on a sliding door, or is it only for swing doors?
Sliding doors are exactly what the 320M is built for. It's a mortise-mounted electromagnet that buries in the pocket or header track rather than surface-mounting on a frame stop the way a standard swing-door mag lock does. The lock body is 1-3/8"H x 7"L x 1-7/8"D and the armature is 1-1/2"H x 4-1/4"L x 5/8"D, so you need a mortise cavity that takes those. If your opening is a swinging door, this is the wrong mount type and you want a surface mag lock instead.
2) Does the Schlage 320M mag lock release the door if the building loses power or the fire alarm trips?
It does. The 320M is a fail-safe device, so cutting power drops the magnet and the door frees immediately. That's the point of tying it into the fire alarm circuit: on alarm the power drops and egress is available. Plan the install accordingly, because it also means a power outage leaves that opening unsecured, and anything you want to stay locked through an outage needs a fail-secure device instead.
3) Can I use the Schlage 320M on a fire rated door assembly?
Yes. The 320M is UL 10C listed for positive pressure fire tests of door assemblies at 3 hours, and it also carries cUL and California State Fire Marshal listing plus ANSI/BHMA 156.23. That combination is what a hospital, school or government facility spec usually asks for on a rated opening.
4) What voltage and current does the Schlage 320M need, and do I have to order a specific voltage version?
One part covers both. Voltage is field selectable between 12 and 24 VDC on the device itself, so you don't pick a voltage at the order stage. Current draw is .23A at 12 VDC and .45A at 24 VDC. Size the supply off whichever rail you select, and remember every door on that supply has to be accounted for.
5) Do I need to buy a separate door contact and bond sensor with the Schlage 320M?
No, the monitoring is built in. Magnetic bond sensor, door status monitor and adjustable relock time delay are standard on the 320M, so your access control panel can see whether the door is closed and whether the magnet has actually bonded without a separate reed switch on the track. Mounting tabs and the armature mounting block come in the box too.
6) I need a mag lock but my doors swing rather than slide. What should I use instead of the Schlage 320M?
The 320M is a sliding door device and won't apply to a swinging opening. For a single outswing door, the DynaLock 2011 is a 1200 lb surface mount from the 2000 Series; the DynaLock 2050 handles outswing or inswing on single or double doors, and the 2250 is the double version. Alarm Controls 1200 Series covers single doors and 1200D covers pairs. If the door is exterior and takes weather, the Alarm Controls 1200WP or the Locknetics WMG Series is the weatherproof route.
7) What is the closest equivalent to the Schlage 320M for a sliding door opening?
The Schlage 320M is a mortise-mounted electromagnetic lock built specifically for sliding doors, with fail-safe operation and 12/24VDC field-selectable power. Among the alternatives, the ROFU 8512 is a single magnet with selectable keyhole mounting rated at 1200 lb holding force on 12/24VDC, and the Dortronics 1000 Series is a dual-voltage 12/24VDC industrial magnetic lock with an SPDT door position switch and sealed, weather-resistant electronics. Both run on the same voltage range as the 320M, so an access control power supply sized for one will serve either. Confirm the mounting geometry against the slider track before ordering, since the 320M mortises into the opening rather than mounting to a header face.
8) What should I use instead of the Schlage 320M on a standard swinging door?
The 320M is designed around a sliding door and mortises into the opening, so a swinging leaf calls for a different body. The DynaLock 2011 is a 1200 lb single electromagnetic lock in the 2000 Series for outswing doors, surface mounted. The DynaLock 2050 Series is a 1200 lb single surface-mounted magnet that covers outswing or inswing on single or double doors, which is the more flexible choice when the swing direction is not settled at order time. For a paired opening, the DynaLock 2250 Series is the double version at 1200 lb, also surface mounted for outswing or inswing.
9) Which magnetic lock should I specify for a fire-rated opening if not the Schlage 320M?
The Schlage 320M carries UL 10C, cUL, CSFM and ANSI/BHMA 156.23, and is fail-safe so the magnet releases when the fire alarm circuit drops power. If the opening needs a swinging-door body with a fire rating, the Dorma EML310 in the DP 628 configuration is a single-door 1500 lb magnet carrying a fire rating with a door position sensor and electrically locked (fail safe) function. The EML310 BA DP 628 adds bond alert to that same single-door 1500 lb fire-rated fail-safe package, which is the closer match to the 320M's magnetic bond sensor. For a double-door fire-rated opening, the Dorma EML320 is the 1500 lb two-leaf version, also fire rated and electrically locked (fail safe).
10) Will the Schlage 320M tie into my existing card reader system and automatic sliding door operator?
It's designed for that. The 320M interfaces with electronic access control systems, automatic door operators, and fire or hazard sensing systems, and it connects to most access control panels through a standard dry relay drop of the power to the magnet. There's no proprietary bus and no reader in the lock, so whatever credential system you already run at the other openings drives this one.
11) Is a shear lock the same thing as the Schlage 320M for a concealed installation?
They both hide in the opening, but they don't work the same way. The 320M is an electromagnet with no moving parts, mortise mounted for a sliding door. A shear lock such as the ROFU 8031-002 uses an interlocking armature and is a different mounting and prep entirely. If you specifically need a concealed device on a sliding door and want the no moving parts, low maintenance approach, the 320M is the one; don't order a shear lock expecting the same prep.
12) Does the Schlage 320M run on batteries or does it need hardwired power?
Hardwired only. There is no battery option on the 320M; it draws continuously from a 12 or 24 VDC supply to hold the magnet energized. Budget a low voltage run to every opening, and if you need the doors to stay locked during an outage, put the supply on battery backup, since the lock itself releases when power drops.
13) I need delayed egress on the opening. Does the Schlage 320M do that, or is there another magnet?
The Schlage 320M's timing feature is an adjustable relock time delay, which governs how long the magnet waits before re-energizing, not a delayed egress cycle. For an opening where code allows a timed hold on egress, the Alarm Controls 1200DE Series is a delayed egress magnetic lock for a single door. The DynaLock 2101 Series is a 1200 lb early warning lock, which annunciates on the attempt at the door. Both are swinging door bodies, so a slider needs the 320M or another sliding-door magnet.
14) Is the ROFU 8031-002 shear lock a substitute for the Schlage 320M?
They solve different problems despite both being concealed rather than surface applied. The ROFU 8031-002 is a shear lock rated at 2200 lb holding force on 12/24VDC with monitoring, and a shear lock holds a swinging leaf against vertical shear at the head. The Schlage 320M is a direct-pull electromagnet mortised for a sliding door, fail-safe, 12/24VDC, with magnetic bond sensor, door status monitor and adjustable time delay built in. A slider moves in the plane the shear lock is not designed to resist, so the two are not interchangeable on the same opening even though both accept the same supply voltage.
15) What is a simpler magnetic lock than the Schlage 320M when I do not need the monitoring outputs?
The 320M ships with magnetic bond sensor, door status monitor and adjustable relock time delay as standard, which is what an access control head end uses to confirm the door is closed and bonded. Where the panel does not read those inputs, the Alarm Controls 1200 Series is a single-door magnetic lock and the 1200D Series is the double-door version, both without the added sensing in their designation. The Locknetics MG Series is offered in 600 lb and 1200 lb models on 12/24VDC in standard or monitored form, so the same family covers both cases if some doors on the job need monitoring and others do not.
16) What finish does the Schlage 320M come in, and will it match aluminum storefront?
628 satin aluminum clear anodized, and that's the only finish offered. The body is aluminum, so it reads the same as clear anodized aluminum storefront and sliding door framing. Most of the lock is concealed in the mortise anyway; the armature face on the leaf is the visible part.
17) Is the Schlage 320M heavy duty enough for a high traffic entrance like a hospital or airport?
It's rated heavy duty for commercial use, and it's a traffic control application device. Because there are no moving parts there's nothing to wear out on a door cycling all day, which is why the 320M shows up in airports, hospitals, nursing homes, schools, universities, libraries, museums, retail and office buildings, labs and government facilities.
18) Can I standardize a facility on the Schlage 320M and one other magnet across all door types?
A common approach is one sliding door body and one swinging door body sharing a supply. The Schlage 320M covers the sliders on field-selectable 12 or 24VDC, fail-safe, with UL 10C, cUL, CSFM and ANSI/BHMA 156.23. For the swinging leaves, the Locknetics MG Series runs 12/24VDC in 600 lb and 1200 lb models, standard or monitored, and the WMG Series is the weatherproof counterpart at the same voltages and holding forces for exterior doors. Keeping the whole set on 12/24VDC means one power supply specification across the building.
19) How does the ACSI 3700 Series compare to the Schlage 320M for an access controlled opening?
The ACSI 3710/3711 is an electromagnetic lock in the 3700 Series. The Schlage 320M differs in the opening it serves and in what it reports: it is a mortise body for sliding doors, fail-safe, running field-selectable 12 or 24VDC at .23A at 12VDC and .45A at 24VDC, with magnetic bond sensor, door status monitor and adjustable relock time delay standard for tying into an access control panel. Size the power supply from those current figures when the 320M is the one going in.
