Corbin Russwin ML20914-LWA-626-SAF – Frequently Asked Questions

1) Do I order the Corbin Russwin ML20914 as fail safe or fail secure?
Both are available on the ML20914, and it is chosen at order time, not in the field. Fail safe (SAF) unlocks the outside lever when power drops, which is what you want on an egress or stair-side opening tied to the fire alarm. Fail secure (SEC) keeps it locked when power drops, which is the usual choice for a perimeter or storeroom door where you never want the opening to free up on a power loss. The ML20914 is a single cylinder, both-grips-lock configuration, so both levers are controlled.
2) Will the ML20914 mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset?
Yes. 1-3/4 inch is the standard door thickness for the ML20914 and 2-3/4 inch is the standard backset, which matches standard commercial mortise prep. The description also notes thicknesses from 1-3/8 inch up to 4 inch and a 2-3/8 inch minimum backset as options, so a thicker door or a narrower-backset prep can be accommodated as a specified option rather than the stock build.
3) Do I have to specify handing when ordering this Corbin Russwin electrified mortise lock?
It is a handed lock, but the latchbolt is quick reversible, so handing can be changed in the field without opening the lock case. That matters if you are stocking locks across a building with mixed swings, or if a door gets rehung after the hardware lands on site.
4) Will this lock latch into my existing ANSI mortise strike?
The ML20914 ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, so it drops into a standard ANSI strike prep in a hollow metal frame. The latchbolt has a 3/4 inch throw with an anti-friction insert, the auxiliary latchbolt gives 9/16 inch effective deadlocking throw, and the deadbolt throws 1 inch. If your frame already has ANSI prep with the same 1-1/8 inch lip to center, the existing strike will engage; if the old lip length is different you will want the supplied strike to keep the lip flush with the frame stop.
5) Can I put this electrified mortise lock on a 3-hour fire rated door?
Yes. The ML20914 is UL and cUL listed to UL10C positive pressure and rated for fire doors up to and including 3 hours, covering a single door up to 4 ft x 10 ft or a pair up to 8 ft x 10 ft. It also meets ADA A117.1 and is certified to California State Fire Marshal and windstorm/hurricane requirements, which is what an institutional spec usually asks for on a rated opening.
6) What keying options do I pick, and can I key it into the cylinders we already use?
Four keying choices are offered on the ML20914: a C 6-pin cylinder in L4 keyway, IC 6-pin less core if you run interchangeable cores, L4 keyway, or less cylinder if you are supplying your own. The standard cylinder is brass, 6-pin L4, 0-bitted. It works with new or existing Corbin Russwin key systems including Access 3 and Pyramid, and it accepts most other manufacturers' cylinders, so an existing masterkey system can usually be carried over. Order less cylinder or less core when your locksmith is pinning to your own system.
7) Should I use an electrified mortise lock like this or a standalone electronic lock with a keypad or card reader?
The ML20914 is a wired electrified mortise lock: it has no reader or keypad of its own and expects an access control head end and a power supply, with electric latch retraction and optional request-to-exit. Choose it when you already run a card access system and want the credential decision made at the panel. If the opening is remote or you do not want to pull power and data to the door, a standalone electronic mortise lock is the better fit. For keypad standalone we carry the Alarm Lock DL3500CR Trilogy, Grade 1 classroom function, and for credential-based standalone the TownSteel FME-2000 Series RFID mortise lock, Grade 1 classroom. For a network-managed wireless option there is the Schlage LEMD-GRW ENGAGE Series, Grade 1 with a 125kHz proximity reader.
8) What is the closest electrified mortise lock to the Corbin Russwin ML20914 from another brand?
Two close cross-brand options. The Schlage L9092EU with 03A trim is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, 12/24VDC, for a 1-3/4 inch door, which lines up with the ML20914's electrified function plus RX and its 1-3/4 inch standard thickness. The BEST 45HW Series is a wired electromechanical heavy duty mortise lock with 12V/24V operation. If you need a field-selectable fail safe or fail secure motorized lock body, the Command Access ML190 Series is a heavy-duty motorized mortise lock with selectable EL/EU operation on 24VDC. Where the ML20914 differs is keying breadth into Corbin Russwin Access 3 and Pyramid systems.
9) If the opening does not need to be wired, what mechanical mortise lock would I use instead of the ML20914?
The ML20914 is an electrified lockset built for Fail Safe or Fail Secure operation with an access control system. For a purely mechanical opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for a 1-3/4 inch door with an interchangeable core option. For an office or entrance function instead of storeroom, the Cal-Royal NM8050 is Grade 1 with an auxiliary deadlatch, and for classroom the Cal-Royal NM8070 covers the same door thickness.
10) Can I use a standalone keypad or credential mortise lock instead of wiring an ML20914 to a panel?
Yes, if you can accept credentials at the door rather than central control. The ML20914 is an electrified Fail Safe/Fail Secure mortise lockset that ties into an access control platform. Standalone alternatives include the Alarm Lock DL3500CR Trilogy, Grade 1 classroom function with 300 user codes for a 1-5/8 to 1-7/8 inch door; the Dormakaba E-Plex E5086 Grade 1 pushbutton/card mortise lock; the Schlage CO-100 standalone electronic mortise lock with keypad reader, Grade 1 privacy function, 1-3/4 inch door; and the TownSteel FME-2000 Series, Grade 1 classroom with RFID for a 1-3/4 inch door. These replace panel wiring with onboard user management.
11) Which mortise locks look like substitutes for the ML20914 but will not work on an electrified opening?
Several mortise products sit in the same family without doing the same job. The Schlage PM010 is a non-keyed Grade 1 passage latch mortise lock and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock, so neither locks or accepts an access control signal. The Schlage L0170 is half dummy trim, Grade 1 non-keyed, with no latch function at all, as are the Emtek 3102 Memphis and 3104 Hamilton dummy mortise entrance locksets. The Kaba Ilco 185 Series and Sargent 4874 are mortise deadbolt functions rather than lever locksets. The ML20914 is a keyed, electrified lever lockset with Fail Safe and Fail Secure functions and an optional request-to-exit switch.
12) My door is 1-5/8 inch thick. Is the ML20914 the right electrified mortise lock, or should I look elsewhere?
The ML20914 is specified for a 1-3/4 inch door. For thinner doors in the 1-5/8 to 1-7/8 inch range, the Alarm Lock Trilogy electronic mortise locks cover that band: the DL2700CR is Grade 1 classroom with a weatherproof design, the DL3500CR is Grade 1 classroom, and the DL4500 Series is a Grade 1 electronic mortise deadbolt with privacy keypad. Those are standalone keypad locks rather than panel-controlled Fail Safe/Fail Secure locksets, so confirm the access control approach before substituting.
13) Is the ML20914 Grade 1, and how many cycles has it been tested to?
It meets ANSI/BHMA A156.13, Series 1000, Operational and Security Grade 1, with a UL cycle verification of 14.5 million cycles (Verification ID V875753). The lock case is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches with a one-piece stainless steel deadbolt. That cycle count is the number to quote when a spec calls for high-traffic mortise hardware in a school, hospital, or transit-type opening.
14) Do I need request-to-exit monitoring on this lock, and can I add it later?
Request to exit (RX) is an order-time option on the ML20914, available with or without. Specify it with RX when the access control system needs to know the inside lever has been turned, typically to shunt an alarm or a door contact on a monitored opening. It is not a field add-on, so decide it with your integrator before the order goes in.
15) What trim and finishes come on the ML20914 -LW, and do the roses match our other openings?
The -LW build uses the Lustra (Wrought) lever. Trim choice is four options: A rose, B rose, M escutcheon, or N escutcheon, so you can match sectional rose openings or full escutcheon openings already in the building. Finishes are 613 satin bronze oil-rubbed, 625 bright chrome, and 626 satin chrome. Trim is thru-bolted for alignment and added pull resistance. If the rest of your doors are 626 satin chrome with roses, the A or B rose in 626 keeps the opening consistent.
16) I only need a mechanical mortise lock, not an electrified one. Is the ML20914 overkill?
Yes, if there is no access control on the opening. The ML20914 is an electrified lock body that needs power and a controller to do anything electrical; on a door with no wiring you are paying for function you cannot use. For plain mechanical Grade 1 mortise locks we carry the Accentra 8805FL storeroom lock, the Cal-Royal NM8080 storeroom or NM8070 classroom, the Cal-Royal NM8050 office/entrance, and the Sargent 7925 dormitory exit function. For a non-keyed opening, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock, field reversible and fire rated.
17) Can one ML2000 lock body cover several door functions so we can standardize stock?
Yes. The ML2054 lock body in this series is multi-function, with 12 functions configurable from the single body, and the latchbolt reverses in the field. For a facility running dozens of openings that means fewer part numbers on the shelf and a lock that can be reconfigured when a room changes use. Note that the ML20914 as built is the single cylinder, both-grips-lock electrified configuration.
18) Will the escutcheon trim clear a narrow stile or a door with a vision light?
The armored front on the ML2000 body is 8 x 1-1/4 inches, and center to center from lever to cylinder is 3-5/8 inches, lever to thumbturn 2-7/16 inches. On the escutcheon options (M or N) those spacings sit on one plate, so you need enough flat stile face to land it. If stile width is tight, the A or B rose options take up less face area for the same lock body.
19) For a behavioral health or ligature-resistant opening, what do I use instead of the ML20914 with a Lustra lever?
The ML20914 uses the Lustra (Wrought) lever. Where ligature resistance drives the trim, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel, passage function, for a 1-3/4 inch door, and the MRX-A-01 is the same passage function with satin stainless ligature-resistant arch trim. For a hospital push/pull opening, the Marks USA 5PDN is a Grade 1 hospital passage mortise paddleset, ligature resistant and ADA compliant in satin stainless steel. All three are passage functions, so they do not provide the keyed electrified control the ML20914 does.
20) Do I need a full ML20914 lockset, or can I buy just a mortise lock body?
The ML20914 ships as a complete electrified lever lockset with trim, orderable with rose or escutcheon and with a 6-pin L4 keyway cylinder, an IC less-core prep, or less cylinder. If the trim is already on the door and only the case is being replaced, lock bodies sold on their own include the BEST 45HCA Series heavy duty mortise lockbody in public entrance function, field reversible, and the 45HCA heavy duty lockbody with intruder function. Baldwin 6301 and 6310 are also sold as mortise lock bodies at a 2-1/2 inch backset, which differs from the 2-3/4 inch backset the ML20914 uses.
21) Is there a Grade 1 wireless mortise lock alternative to running wire for the ML20914?
Yes. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED, Greenwich trim, right hand, with a 3 hour fire rating. The Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. The ML20914 is a hardwired Fail Safe/Fail Secure lockset, so the wireless options shift credential handling to the door and change how egress and monitoring are handled; the ML20914 offers request-to-exit monitoring as an ordering option.
22) Does this lock reduce power draw on a large access control job?
The ML2000 electrified locks use EcoFlex technology, quoted at up to 89 percent energy savings, and the ML20900 series offers Motorized Electric Latch Retraction rather than a continuously energized solenoid. On a building with many electrified openings that changes how much power supply capacity you have to design in, which is worth raising with whoever sizes the panels and supplies.
