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

1) What is the difference between the Fail Safe and Fail Secure versions of the Corbin Russwin ML20914 electrified mortise lock?
Both modes are offered on the ML20914, and you pick one when you order. Fail Safe unlocks the lever when power drops, which is what you want on an egress path or a stair door tied into the fire alarm. Fail Secure keeps the lever locked when power drops, so the opening stays secure and free egress comes from the inside lever. The lock itself is the same ML2000 Series electrified mortise body either way, so the choice is about how the opening has to behave in a power loss, not about the hardware spec.
2) Will the ML20914 mortise lockset fit my door and existing mortise pocket?
It is a standard commercial mortise prep: 2-3/4 inch backset, 1-3/4 inch door thickness, with a heavy-gauge steel lockcase measuring 5-7/8 x 4 x 15/16 inches and an 8 x 1-1/4 inch armored front. The description also notes the lockset accommodates door thicknesses from 1-3/8 inch up to 4 inches with optional thickness parts. If your door is already cut for an ANSI mortise body at a 2-3/4 backset, this drops into that pocket.
3) Will this Corbin Russwin lock latch into the ANSI strike already in my frame?
The ML20914 uses a 3/4 inch throw two-piece anti-friction latchbolt with a 9/16 inch deadlocking auxiliary latch, and ships with an ANSI straight lip strike measuring 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame carries a standard ANSI 4-7/8 strike prep, the latch lines up. Check your lip-to-center against the 1-1/8 inch figure if you have a deep stop or an applied frame face.
4) Do I have to specify handing when I order this electrified mortise lock?
The ML20914 is a handed lock, but the latchbolt is field reversible. The patented Quick Reversible latchbolt lets you change the hand without opening the lock case, so a lock delivered for the wrong hand can be corrected on the job rather than returned.
5) What keying options can I order the ML20914 with, and can I key it to my existing Corbin Russwin system?
Four keying choices are offered: a conventional L4 keyway cylinder, an IC 6-pin cylinder in L4 keyway, IC 6-pin less core, and less cylinder. Standard cylinders are brass, 6-pin L4, 0-bitted. It works with new or existing Corbin Russwin key systems, and it accepts most other manufacturers' cylinders, so it can be brought into a house keyway you already run. If your integrator supplies cores, order less core or less cylinder.
6) Can I use this lock on a fire rated door?
Yes. The ML20914 is UL and cUL listed, UL10C positive pressure, for fire doors rated up to and including 3 hours, on singles up to 4 by 10 feet and pairs up to 8 by 10 feet. It also carries ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and ADA A117.1 compliance.
7) What is the closest equivalent to the Corbin Russwin ML20914-CS from another manufacturer for an electrified mortise lock tied into access control?
The Schlage L9092EU with 03A trim is the nearest match: it is a heavy duty mortise lock with an electrically controlled outside lever, keyed outside, request-to-exit switch, and 12/24VDC operation for a 1-3/4 inch door. The ML20914-CS covers the same ground with Fail Safe and Fail Secure builds, request-to-exit monitoring offered as an option, and a 2-3/4 inch backset. The Schlage part is a corridor function assembly; the Corbin Russwin is a single cylinder both-grips lock on the ML2000 lockbody.
8) If I want to choose fail safe or fail secure in the field instead of ordering one or the other, what electrified mortise lock should I look at?
The Command Access ML19092-M is a motorized mortise lock with field selectable EL/EU operation on 24VDC, so one part covers both electrically locked and electrically unlocked modes after it is installed. The Corbin Russwin ML20914-CS is ordered as either a Fail Safe or a Fail Secure build, so the mode is decided at the purchase order. If a job has not settled its egress strategy, the field selectable unit avoids a second order.
9) We do not have power or wiring at the door. What mortise lock should we use instead of the ML20914-CS?
A standalone electronic mortise lock removes the wiring run. The Alarm Lock DL3500CR is a Grade 1 classroom-function electronic mortise lock with 300 user codes for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone keypad mortise lock in privacy function for 1-3/4 inch doors. The ML20914-CS is a wired electrified lockset intended to be driven by an access control system, so it needs power at the frame.
10) Does a Schlage LE Series mobile-enabled mortise lock replace the ML20914-CS on a fire-rated opening?
Check the grade before you swap. The Schlage LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with a 3 hour fire rating, while the LEMD-GRW ENGAGE wireless mortise lock is Grade 1 with a 3 hour fire rating. The ML20914-CS is an ANSI/BHMA A156.13 Grade 1 mortise lock listed for fire doors up to 3 hours. If the spec calls Grade 1, the LEBMB-ADD does not meet it.
11) For a narrow stile aluminum storefront door, can I use the ML20914-CS?
The ML20914-CS is built on a heavy-gauge steel ML2000 lock case measuring 5-7/8 by 4 by 15/16 inches for a 1-3/4 inch door, which is a wide stile hollow metal or wood application. For aluminum storefront, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, and the Kaba Ilco BR Series is a glass door bottom rail lock. Those are the storefront-oriented choices.
12) Do I need request-to-exit monitoring on an electrified mortise lock, and is it available here?
Request to exit is an ordering option on the ML20914, yes or no. Specify yes when the access control system needs to know the inside lever has been turned, so the door contact does not report a forced opening on a legitimate exit, or when you are shunting an alarm. If the lock is simply being energized to lock and unlock with no monitoring back to the panel, you do not need it.
13) What trim and finishes does the Corbin Russwin ML20914-CS come in?
The lever is the CS Citation cast design. Trim mounts as A rose, B rose, M escutcheon or N escutcheon, and trim is thru-bolted for alignment and added security. Finishes are 605 bright brass, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome and 630 satin stainless steel, so matching 626 or 630 openings across a building is straightforward.
14) Is there a deadbolt in this mortise lock, and how far does it throw?
Yes. The ML2000 body carries a one-piece stainless steel deadbolt with a full 1 inch throw, measuring 19/32 by 1-1/4 inches. Center to center spacing is 3-5/8 inches lever to cylinder and 2-7/16 inches lever to thumbturn, which is what you check against an existing door face prep before ordering.
15) Should I buy an electrified mortise lock like this or a standalone keypad mortise lock?
The ML20914 is a wired electrified lock: it has to be fed power through the frame and door and tied to an access control panel, and it gives you central control, real-time lock and unlock, and request to exit. If you have no wiring to the opening, a standalone lock makes more sense. ZenSupply carries the Alarm Lock DL3500CR Trilogy Grade 1 electronic mortise lock with 300 user codes and classroom function, and the TownSteel FME-2000 Series Grade 1 RFID mortise lockset, both of which run on-board credentials rather than a panel. For a wired alternative from another brand, the BEST 45HW Series wired electromechanical mortise lock runs 12V or 24V.
16) What other electrified mortise locks compare to the Corbin Russwin ML20914?
Closest in concept are the Schlage L9092EU with 03A trim, an electric lock/unlock outside lever mortise lock with request to exit, keyed outside, 12/24VDC, listed at 1-3/4 inch door thickness; and the Command Access ML190 Series motorized mortise lock with field selectable EL/EU operation on 24VDC, storeroom function. The Schlage and Corbin units are both fixed to one electrical mode per order in the way you spec them, while the Command Access body lets you flip between electrically locked and electrically unlocked in the field.
17) I only need a mechanical mortise lock, no electrification. What should I look at instead?
If the opening has no power and no access control, skip the electrified ML20914 and buy a mechanical body. ZenSupply carries the Cal-Royal NM8080 Grade 1 storeroom mortise lockset with interchangeable core option and the NM8070 classroom version, both at 1-3/4 inch door thickness, plus the Accentra 8805FL Grade 1 storeroom mortise lock with Arcadia lever and the Sargent 7925 Grade 1 dormitory exit function mortise lock with single cylinder deadbolt.
18) What is a wired electrified mortise alternative if I am standardized on BEST cores rather than the Corbin Russwin L4 keyway?
The BEST 45HW is a wired electromechanical mortise lock rated heavy duty with 12V/24V operation, which keeps an electrified opening inside the BEST platform. The ML20914-CS is offered with an L4 keyway, IC 6-pin L4 cylinder, IC 6-pin less core, or less cylinder, so it can also be taken less core and stuffed with your own interchangeable core if you would rather keep one lock body across the building.
19) Is a credential-reading mortise lock like the TownSteel FME-2000 a substitute for the Corbin Russwin ML20914-CS?
They solve different problems. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with an RFID reader built into the lock for 1-3/4 inch doors, meaning the credential decision happens at the door. The ML20914-CS has no reader of its own; it is a Fail Safe/Fail Secure electrified lockset whose lever is controlled by a separate access control panel and reader. Use the TownSteel where there is no head-end system, and the Corbin Russwin where there is one.
20) Our door is 1-5/8 inches thick. Will the Corbin Russwin ML20914-CS work, or do I need something else?
The ML20914-CS is catalogued at a 1-3/4 inch door thickness. Electronic mortise locks in the Alarm Lock Trilogy line, including the DL2700CR classroom lock and the DL4500 electronic mortise deadbolt, are listed for 1-5/8 inch to 1-7/8 inch doors, which brackets a 1-5/8 inch leaf directly.
21) Can I order just the mortise lock body and reuse the existing trim rather than a complete ML20914-CS lockset?
The ML20914-CS is supplied as a complete lockset with the CS-Citation lever and a choice of A or B rose or M or N escutcheon trim. If you only need a body, the BEST 45HCAC is a heavy duty mortise lock body in public entrance function with field reversible operation and the 45HCAINL is a heavy duty mortise lockbody in intruder function. Those are bodies, not finished trim sets.
22) For a behavioral health or anti-ligature opening, is the ML20914-CS the right lever, or is there a better choice?
The ML20914-CS uses the CS-Citation cast lever, a conventional return lever. For ligature-resistant openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function, the MRX-A-01 is the same duty with ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant. All three are non-keyed passage-type trim rather than electrified.
23) We are matching handing on an existing opening. How does the ML20914-CS compare to other field reversible mortise locks?
The ML20914-CS is field reversible, with a quick reversible latchbolt that re-hands without disassembling the lock case. The Falcon MA101 Grade 1 heavy duty mortise passage lock and the BEST 45HCAC mortise lock body are also field reversible. By contrast, the Schlage LEMD-GRW ENGAGE wireless mortise lock is catalogued right hand, and the Baldwin 6310190RRLS is a right hand reverse build, so those are ordered to the handing of the door.
24) How does the ML20914-CS compare to a Dormakaba E-Plex mortise lock for a building with no access control head end?
The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back-to-back configuration, and the E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors. Both manage credentials at the door. The ML20914-CS is a Grade 1 mortise lockset whose Fail Safe or Fail Secure lever is driven by external power and control wiring, and it takes a keyed cylinder in an L4 keyway or an interchangeable core.
25) Is this the right lock for a high-traffic opening in a school or hospital?
It is built for that duty. The ML2000 body is heavy-gauge steel, meets ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, and has been UL cycle tested to 14.5 million cycles. The two-piece anti-friction latchbolt takes less force to close, which matters on doors with closers and on stacked openings that get hit all day.
26) What is the difference between the ML20914-CS and a mortise deadbolt like the Sargent 4874?
The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. Those are bolt-only bodies with no lever and no latchbolt operation. The ML20914-CS is a full lever lockset with a 3/4 inch latchbolt and an ANSI straight lip strike at 1-1/8 inch lip to center, plus electrified control of the lever. A deadbolt cannot substitute where the door needs latching and access-controlled egress.
27) Is a Hager 3800 Series mortise lock an equivalent to the ML20914-CS?
Not for an access-controlled door. The Hager 3850E is an office function mortise lock, non-keyed, with lever and escutcheon on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the 3810S and 3810E are passage function on the same backset. They share the 2-3/4 inch backset with the ML20914-CS, but they are mechanical trim with no electrified Fail Safe or Fail Secure control and no request-to-exit option.
28) What looks like a mortise lockset but will not work as a replacement for the ML20914-CS?
Dummy trim. The Schlage L0170 is a Grade 1 mortise non-keyed half dummy trim, the Falcon MESC600DT is dummy escutcheon lever trim for M9900 exit devices, and the Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan are dummy function mortise entrance locksets. None of them latch or lock. The ML20914-CS is a working single cylinder lockset with a 3/4 inch latchbolt and electrified lever control.
