Dorma EML310 Electromagnetic Lock, Single Door, 1500 lb., Door Position Sensor

Yes. The EML310 is a fail safe device, electrically locked: it holds the door only while power is applied and releases the moment power drops. That is what makes it usable on egress doors, and it also means a power failure leaves the opening unsecured, so pair it with a supervised supply if the door protects something. If you need the door to stay locked without power, a magnetic lock is the wrong technology entirely.

Yes, this version includes a door position sensor, so the lock reports door open or closed back to the access control panel or alarm system. That is what lets you alarm a propped or forced door instead of just cutting power to the magnet. If you also want positive confirmation that the magnet has bonded to the armature, the Schlage M390RFK adds a magnetic bond sensor alongside door status monitoring.

The EML310 is an electrically locked fail safe magnet for single doors, which releases on power loss but does not itself provide a timed egress delay. For a delayed egress opening the Alarm Controls 1200DE Series is a delayed egress magnetic lock for a single door, and the DynaLock 2101 Series is an early warning lock rated at 1200 lb. Those are the bodies that carry the nuisance delay and alarm sequence a delayed egress installation is specified around.

The Dorma EML310 is a single-door electromagnetic lock rated at 1500 lb holding force running on 12/24 VDC. The Schlage Electronics M390RFK is also a 1500 lb holding force electromagnetic lock, built as a heavy duty unit in the M390 Series, and it carries a door status monitor plus a magnetic bond sensor and relock time delay. It is also specified as a direct retrofit for the Locknetics 390+, so on an opening already carrying a 390+ the M390RFK drops into the existing prep. Both units are surface magnets sized for a single door leaf at the same holding class.

The Dorma EML310 is supplied with a door position sensor on a 1500 lb single door magnet. Among the alternatives, the Schlage M390RFK carries a door status monitor and a magnetic bond sensor along with a relock time delay, the Dortronics 1000 Series includes an SPDT door position switch, the ROFU 8031-002 is a monitored shear lock, and the Locknetics MG Series is offered in a monitored version. Those are the units that report door state back to the access control panel rather than just holding the leaf.

No. The EML310 is a surface electromagnetic lock for single doors at 1500 lb holding force, mounted with the magnet on the frame and the armature on the leaf. The ROFU 8031-002 is a shear lock rated at 2200 lb holding force on 12/24 VDC and monitored, and a shear lock concealed in the header engages a bolt into the top of the door rather than holding face to face. The Schlage 320M is a compact mortise electromagnetic lock at 1500 lb built for a sliding door. They are different mounting families and are not interchangeable with a surface magnet without changing the door prep.

No handing to specify. The EML310 is non handed, so the same unit goes on a left or right hand opening. The mounting decision is about swing and frame condition, not hand.

The EML310 is fire rated. On a fire door the maglock still has to release on fire alarm and comply with the egress requirements for that opening, so the release path (fire alarm interface, request to exit, and any pushbutton) is part of the design, not an accessory.

The EML310 is a standard interior duty surface mag lock, not a sealed or weatherproof unit. For an exposed opening use a weather rated model: the Alarm Controls 1200WP, the Locknetics WMG Series, or the Dortronics 1000 Series with sealed electronics.

The EML310 is a 1500 lb single door magnet. Where an interior opening does not need that holding class, the Schlage M420 is an electromagnetic lock at 500 lb holding force for a single door, and the Locknetics MG Series is offered in 600 lb and 1200 lb models on 12/24 VDC in standard or monitored form. The Dortronics 1107 is a narrow 2 inch slim line 600 lb single door mag lock, which is the one to look at when the header face is tight.

Commercial. The EML310 is a commercial grade electromagnetic lock at 1500 lb holding force, intended for access controlled openings in commercial and institutional buildings rather than a home door.
