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

1) Should I order the Corbin Russwin ML20914 as fail safe or fail secure?
Both modes are orderable on the ML20914, and it's a choice you make on the order, not in the field. Fail safe (SAF) unlocks the lever when power drops, which is what you want on an egress-critical or stair-side opening tied to the fire alarm. Fail secure (SEC) keeps the outside lever locked when power is lost, which is the normal pick for a tenant suite or storeroom where you never want the door to free up during an outage. Either way the inside lever always retracts the latch for egress, and the key override works on the keyed side.
2) Will the ML20914 mortise lock fit a 1-3/4 inch commercial door?
Yes. 1-3/4 inches (44mm) is the standard door thickness for the ML2000 Series lockbody, and the ML20914 uses the standard 2-3/4 inch backset with a 5-7/8 x 4 x 15/16 inch lockcase pocket. Optional thicknesses are available for doors outside that standard, up to 4 inches.
3) Do I have to specify handing when I order this Corbin Russwin electrified mortise lock?
The lock is handed as shipped but field reversible. The ML2000 latchbolt is a patented quick-reversible design, so a locksmith can re-hand it without opening the lock case. Useful when a door gets rehung or when you're stocking spares for a building with mixed handing.
4) Will the ML20914 latch into the strike prep already in my frame?
It ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center, and the latchbolt has a 3/4 inch throw. If your frame is already cut for a standard ANSI mortise strike, this drops in. The auxiliary latchbolt gives 9/16 inch effective throw and deadlocks the main latch against carding.
5) Can I use the ML20914 on a 3-hour fire rated door?
Yes. The ML2000 mortise lock is UL/cUL listed and UL10C positive pressure compliant, rated for fire doors up to and including 3 hours, on single doors to 4 ft x 10 ft and pairs to 8 ft x 10 ft. It's also ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, and ADA A117.1 compliant, plus California State Fire Marshal and windstorm/hurricane certified.
6) Can I key this Corbin Russwin mortise lock into my existing building key system?
Yes. Four keying choices are offered: a conventional 6-pin cylinder in the L4 keyway, L4 keyway, interchangeable core 6-pin less core (for your own SFIC), and less cylinder if you're supplying your own. Conventional cylinders ship 0-bitted as standard. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so it can be folded into a masterkey system you already run.
7) What is the closest cross-brand equivalent to the Corbin Russwin ML20914-PS electrified mortise lockset?
The closest peer is the Schlage L9092EU electrified mortise lock in the 03A trim, 626 finish, which is a heavy duty mortise lock with electric lock/unlock of the outside lever, keyed outside, request-to-exit monitoring, 12/24VDC, for 1-3/4 inch doors. The ML20914-PS is likewise an electrified mortise lever lockset offered in Fail Safe and Fail Secure functions with a Request to Exit Monitoring option and a 626 satin chrome finish. The Schlage is catalogued with a corridor function, while the ML20914 is configured as a single cylinder, both grips lock in the ML2000 Series with a 2-3/4 inch backset.
8) Is there another electrified mortise lock where fail safe and fail secure can be selected in the field instead of ordered as separate items?
Yes. The Command Access ML190 Series motorized mortise lock, part ML19092-M, is a heavy-duty storeroom-function unit with field selectable EL/EU operation on 24VDC, so one lockbody covers both fail safe and fail secure. On the Corbin Russwin ML20914-PS the Fail Safe and Fail Secure modes are chosen as the Function when ordering.
9) If the opening needs a keypad or credential reader at the door rather than wiring to an access control panel, what mortise lock should be used instead of the ML20914-PS?
Standalone options carry the reader on the lock itself. The Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors; the Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader, privacy function, 1-3/4 inch doors; and the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. The Corbin Russwin ML20914-PS instead takes its signal from an access control system in Fail Safe or Fail Secure mode.
10) For a classroom or lockdown opening, is the ML20914-PS the right choice or is there a better-suited mortise lock?
The ML20914-PS is configured as a single cylinder, both grips electrified lockset in Fail Safe or Fail Secure operation, driven by an access control system. Where the requirement is a dedicated classroom or intruder function at the door, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike and an 8-1/2 by 2-3/4 by 7/16 inch steel escutcheon, the BEST 45HCAINL is a heavy duty mortise lockbody with intruder function, and the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID.
11) Is the Schlage LE Series LEBMB-ADD an equivalent grade to the Corbin Russwin ML20914-PS?
No. The Schlage LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, for 1-3/4 inch doors, rated 3 hours fire. The Corbin Russwin ML20914-PS is certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1. If a specification calls for Grade 1, the LE Series will not satisfy it.
12) Do I need request-to-exit monitoring on an electrified mortise lock, and can I get it on this one?
Request to exit is an orderable option on the ML20914, yes or no. Order it with RX when the access control system needs to know the inside lever was turned, so it can shunt the door alarm on authorized egress instead of reporting a forced door. If the opening is just remote-release with no monitoring, skip it.
13) What trim and lever do I get with the ML20914-PS, and what are the rose and escutcheon choices?
The PS suffix is the Princeton cast lever, and the configuration is single cylinder with both grips locked. Trim is offered as A or B rose, or M, N or R escutcheon, all in 626 satin chrome. Trim is thru-bolted for alignment and added pull resistance. Center to center is 3-5/8 inches lever to cylinder and 2-7/16 inches lever to thumbturn, which is what governs whether the escutcheon covers an existing trim cutout.
14) What is the difference between this electrified mortise lock and a standalone keypad or credential mortise lock?
The ML20914 is a wired electrified lockset: it has no reader or keypad of its own and expects an access control panel, power supply and wiring to the door. If you don't have a head-end and just need controlled access on one or two doors, a standalone unit makes more sense, such as the Dormakaba E-Plex 2066 pushbutton mortise lock or the Schlage CO-100 standalone electronic mortise lock. For networked wireless without home-running wire, the Alarm Lock DL1300NW Trilogy Networx is a wireless keypad mortise option.
15) Is an electrified mortise lock overkill if I just need a keyed storeroom or classroom door?
If there's no access control on the opening, yes, you're paying for electrification you won't wire. A straight mechanical Grade 1 mortise lock covers it: Cal-Royal NM8080 storeroom or NM8070 classroom, both Grade 1 for 1-3/4 inch doors, or the Accentra 8805FL Grade 1 storeroom mortise with Arcadia lever. Keep the ML20914 for doors that need remote lock or unlock from a panel.
16) What is a simpler mechanical mortise lock if the door does not need electrification?
For a mechanical opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch. None of these carry the Fail Safe or Fail Secure electrified operation of the Corbin Russwin ML20914-PS.
17) Will a BEST 45HW wired mortise lock work as a substitute for a Corbin Russwin ML20914-PS?
The BEST 45HW is a heavy duty wired electromechanical mortise lock in the 45HW Wired Mortise Series with 12V/24V operation, so it addresses the same electrified-opening job as the ML20914-PS. The two are different lock cases and different trim systems, so the strike prep, cylinder, and keying carry over from neither to the other: the ML20914 uses a 6-pin L4 keyway cylinder and takes a 2-3/4 inch backset with an ANSI straight lip strike at 1-1/8 inch lip to center. Verify door prep before treating either as a drop-in for the other.
18) Which mortise locks look like alternatives to the ML20914-PS but will not control access on the door?
Several mortise items in the same family do no locking at all. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock, the Hager 3810S and 3810E are Grade 1 passage mortise locks with a 2-3/4 inch backset in rose and escutcheon trim respectively, and the Schlage L0170 is a Grade 1 half dummy trim with no latch function. The Emtek 3102 Memphis and 3106 Manhattan mortise entrance locksets are also dummy function. The Corbin Russwin ML20914-PS is a keyed, electrified Fail Safe/Fail Secure lockset and is not interchangeable with any of them.
19) Are there mortise lock alternatives for a behavioral health or ligature-resistant opening instead of a lever lockset?
Yes. The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant, satin stainless steel. Those three are passage function; the Corbin Russwin ML20914-PS is a keyed electrified lockset offered with Princeton cast lever trim on rose or escutcheon.
20) What differentiates the Corbin Russwin ML20914-PS from a wireless or mobile-credential mortise lock like the Schlage LEMD-GRW?
The Schlage 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, rated 3 hours fire. It carries its own reader and radio at the door. The ML20914-PS is a hardwired electrified mortise lockset that takes Fail Safe or Fail Secure operation from the access control system, with optional Request to Exit monitoring and keying choices including a 6-pin L4 keyway cylinder or IC 6-pin less core.
21) For a 1-3/4 inch door, which electrified mortise alternatives fit and which do not?
The Corbin Russwin ML20914-PS is specified for a 1-3/4 inch door thickness with a 2-3/4 inch backset. Among electrified peers, the Schlage L9092EU in 03A trim and the Schlage CO-100-MS-40-KP are both listed for 1-3/4 inch doors, and the TownSteel FME-2000 and FME-4000 likewise. The Alarm Lock Trilogy DL2700CR, DL3500CR and DL4500 are listed for 1-5/8 to 1-7/8 inch doors, a different range that should be checked against the leaf before ordering.
22) Which mortise locks are handed and which can be reversed in the field?
The Corbin Russwin ML20914-PS is field reversible, using a patented quick reversible latchbolt that re-hands without disassembling the lock case. The BEST 45H Series public entrance mortise lock body is also described as field reversible, and the Falcon MA101 Grade 1 heavy duty passage lock offers field reversible operation. By contrast the Schlage LEMD-GRW is supplied right hand, and the Baldwin 6310190RRLS is a right hand reverse lever mortise lock with a 2-1/2 inch backset, so handing must be confirmed at order time on those.
23) How durable is the ML2000 lock body for a high-traffic entrance?
The lockcase is heavy-gauge steel and UL cycle tested to 14.5 million cycles (verification ID V875753), well past the Grade 1 operational minimum. The two-piece anti-friction latchbolt also cuts the closing force needed, which matters on a door with a closer that sees constant use. Deadbolt is one-piece stainless with a 1 inch throw.
24) Can I change the lock function later without replacing the whole lock body?
Within the ML2054 multi-function lockbody, twelve functions are configurable from the one body, so a facility can standardize on fewer part numbers and reconfigure as room use changes. Status indicator options for locked/unlocked visibility are also available on sectional and escutcheon trims if occupants need to see the state from the corridor.
25) Can a mortise deadbolt be used instead of the ML20914-PS electrified lockset?
Not as a substitute for latching. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, the Kaba Ilco 185 Series is a no-handing mortise deadbolt lock, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad for 1-5/8 to 1-7/8 inch doors. Deadbolts throw a bolt only. The Corbin Russwin ML20914-PS is a lever lockset with a 3/4 inch latchbolt and an ANSI straight lip strike, so it latches the door on closing as well as securing it.
