Dorma EML320 Electromagnetic Lock, Double Door, 1500 lb.

Plan on a clear header run of 21-1/8 inches. The EML320 body measures 21-1/8 x 2-7/8 x 1-5/8 inches, so a narrow transom bar or a frame head with limited flat face will not take it. Measure the header face and the depth available behind the stop before you commit; on a pair with a decorative head casing this is the number that decides the job.

Yes. The EML320 is fail safe, electrically locked, which means the magnet only holds while it's energized. Cut power, drop the fire alarm relay, or hit the release and the doors free immediately. That's the behavior code officials expect on an egress opening, and it's why a mag lock can't be your only security on a door that also needs to stay locked during a power failure.

The EML320 carries a fire rating, so it's suitable for a fire rated opening. Being fail safe, it releases the doors when the alarm system drops power, which is how a mag lock is meant to behave on a rated egress pair. It has to be tied into the fire alarm so that release happens automatically.

For a single leaf, the DynaLock 2011 is a single electromagnetic outswing lock at 1200 lb in the 2000 Series surface mount line, and the DynaLock 2050 Series is a single electromagnetic lock at 1200 lb, surface mounted for outswing or inswing. The Alarm Controls 1200 Series is a single magnetic lock line, and the Dortronics 1107 is a narrow 2 inch slim line 600 lb single door mag lock for tight stiles. The Dorma EML320 is built for double outswinging interior or perimeter doors and measures 21-1/8 inches by 2-7/8 inches by 1-5/8 inches, a header run sized for a pair.

No. The Dorma EML320 is an electrically locked fail safe electromagnetic lock, meaning it releases when power is removed, with no delay function stated in its description. When the code official is asking for delayed egress, the Alarm Controls 1200DE Series is a delayed egress magnetic lock for a single door, and the DynaLock 2101 Series is a 1200 lb early warning lock. Those are different devices, not trim options on the EML320.

The DynaLock 2250 Series is the nearest peer for double-door work. It is a double electromagnetic lock rated at 1200 lb holding force, surface mounted, and rated for outswing or inswing single or double doors. The Dorma EML320 is a double-door electromagnetic lock at 1500 lb holding force, non-handed, running on 12/24 VDC, and is intended for double outswinging interior or perimeter doors. The Alarm Controls 1200D Series is also a double magnetic lock line. The main split is holding force and swing coverage: the 2250 covers both inswing and outswing, while the EML320 is specified for outswinging openings.

No handing to specify. The EML320 is non-handed, so the same unit works regardless of which way the pair is hung. That matters when you're standardizing a building: one part number covers every outswinging pair on the property rather than stocking two.

Self drilling TEC screws are the mounting fasteners, so the magnet body goes onto a hollow metal header without pre-tapping. You still drill the wire pass-through and set the armature on each leaf; a drill, a bit for the cable hole, and a driver is most of what the install takes.

Several peers state monitoring in their own descriptions. The Schlage M390RFK carries a door status monitor and magnetic bond sensor along with a relock time delay at 1500 lb holding force. The Locknetics MG Series is offered in standard or monitored versions. The Dortronics 1000 Series includes an SPDT door position switch. The ROFU 8031-002 shear lock is monitored. The Dorma EML320 is the 1500 lb fail safe magnet for a pair of outswinging doors, non-handed, on 12/24 VDC.

No. The ROFU 8031-002 is a shear lock rated at 2200 lb holding force, 12/24VDC, monitored. A shear lock is a different mounting and engagement style from a surface direct-hold magnet like the Dorma EML320, which mounts with self drilling TEC screws, measures 21-1/8 inches by 2-7/8 inches by 1-5/8 inches, and holds at 1500 lb on 12/24 VDC across a pair of outswinging doors. The ROFU 8512 is another distinct mounting approach, a standard single magnet with selectable keyhole mount at 1200 lb on 12/24VDC. Confirm which prep the frame already has before ordering across these.

The Dorma EML320 runs on 12/24 VDC. Peers on the same dual voltage include the Dortronics 1000 Series, which is field selectable 12/24VDC, the Locknetics MG Series and WMG Series, both 12/24VDC, the ROFU 8512 at 12/24VDC, and the ROFU 8031-002 at 12/24VDC. If a facility is standardizing on one power supply across several openings, those units share the supply voltage with the EML320.

No. The EML320 mounts to the header of a swinging outswing pair with an armature on each leaf, which a sliding door has no face for. For a sliding opening at the same 1500 lb holding force, the Schlage Electronics 320M is a compact mortise sliding door electromagnetic lock.

No. The Dorma EML320 is non-handed, so one part number covers left and right hand double outswinging openings. Among the peers, the DynaLock 2050 Series and DynaLock 2250 Series are described as surface mounted for outswing or inswing single or double doors, and the DynaLock 2011 is specifically an outswing single lock, so swing direction rather than hand is the thing to confirm when cross shopping these.
