Corbin Russwin ML20914-DSA-626-RH-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 are ordered off the same ML20914 lockset, and the choice is about what the door does when power drops. Fail Safe unlocks the outside lever on power loss, which is what you want on an egress path or a stair door tied into fire alarm release. Fail Secure keeps the outside lever locked when power is lost, so the opening stays secured and free egress is still handled by the inside lever. Fail Safe and Fail Secure are separate orderable versions, so pick before you order rather than changing it in the field.
2) Will the Corbin Russwin ML20914 mortise lockset fit a 1-3/4 inch door with a 2-3/4 inch backset?
Yes, that is the standard prep for it. The ML20914 is built for 1-3/4 inch doors with a 2-3/4 inch backset, and the description covers thicknesses from 1-3/8 inch minimum up to 4 inch maximum with optional thickness kits, and backsets from 2-3/8 inch to 2-3/4 inch. The lockcase itself is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches with an 8 x 1-1/4 inch armored front, so the door pocket has to be a standard ANSI mortise prep. It goes into wood, hollow metal, and bullet-resistant doors.
3) Do I have to order the ML20914 handed, or can it be reversed on site?
Handing is an order choice, left or right, but it isn't a trap if you get it wrong. The ML20914 uses Corbin Russwin's quick reversible latchbolt, so the hand can be changed in the field without taking the lock case apart. Useful if you're stocking spares for a building with openings swinging both ways.
4) Will the ML20914 latch into an existing ANSI mortise strike in my frame?
It should, if the frame carries a standard ANSI strike prep. The lock 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 is a two-piece anti-friction unit with a 3/4 inch throw. There's also a 9/16 inch deadlocking auxiliary latch and a 1 inch stainless deadbolt with 1 inch throw, so the frame needs the deadbolt pocket as well as the latch pocket. If your existing strike is a T-strike or a non-ANSI lip, swap it for the supplied one.
5) What is request-to-exit monitoring on the ML20914 and do I need it?
RX is an internal switch that signals your access control panel the moment someone turns the inside lever, so the system reads the egress as authorized instead of firing a forced-door alarm. Order it if the opening is monitored by a door contact and tied to an access control head end. If the lock is simply being powered to lock and unlock with no monitoring, skip it. The ML20914 is offered both with and without RX, and it is not something you add later.
6) What keying options can I get on the Corbin Russwin ML20914, and will it take my existing cylinders?
Four ways to order it: conventional 6-pin cylinder in L4 keyway, L4 keyway, interchangeable core prep less core, or less cylinder entirely. The standard cylinder is brass, 6-pin L4, supplied 0-bitted. If you're on an existing Corbin Russwin key system it can be brought into that system, and the lock also accepts most other manufacturers' cylinders, so a locksmith standardizing a building on another keyway can order it less cylinder and supply their own.
7) Is the Corbin Russwin ML20914 approved for a fire-rated door?
Yes. It is UL and cUL listed, UL10C positive pressure, and carries a fire door rating up to and including 3 hours, good to 4 ft x 10 ft on a single door or 8 ft x 10 ft on a pair. It also holds California State Fire Marshal listing and windstorm/hurricane certification, and the lever trim meets ADA A117.1. Grade-wise it is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1.
8) I don't have power at the door. Is there a mechanical mortise lock I should buy instead?
Yes, the ML20914 is an electrified lockset and needs power run to the opening, so it is the wrong part for a door with no wiring. For a straight mechanical Grade 1 mortise on a 1-3/4 inch door, the Cal-Royal NM8080 storeroom lockset and the Cal-Royal NM8070 classroom lockset are both Grade 1 mortise locks with auxiliary deadlatch, and the Accentra 8805FL is a Grade 1 storeroom mortise from the 8800 Series. If you want standalone electronic access without running wire, the Alarm Lock DL3500CR Trilogy is a Grade 1 battery keypad mortise lock.
9) What is the closest cross-brand equivalent to the Corbin Russwin ML20914-DS electrified mortise lockset?
The Schlage L9092EU with 03A trim is the nearest peer: 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-DS is an electrified mortise lever lockset built on a 2-3/4 inch backset for a 1-3/4 inch door, orderable in Fail Safe or Fail Secure and with or without request to exit monitoring. Both cover the same electrified-access opening; the Corbin Russwin is ordered as a single part number with the Fail Safe or Fail Secure mode selected, while the Schlage part is a fixed electrically unlocked configuration.
10) If I do not need the lock wired to an access control panel, what mechanical mortise lock can I use instead of the ML20914-DS?
For an opening with no electrified control, the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for a 1-3/4 inch door with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with the Arcadia lever. Both are key-operated only. The ML20914-DS is the electrified version of the same opening type, ordered Fail Safe or Fail Secure so the outside lever is controlled by power, and can be specified with an IC 6-pin less core prep if you key it into an interchangeable core system.
11) Is the Command Access ML190 a substitute for the Corbin Russwin ML20914-DS?
It covers similar ground. The Command Access ML190 Series is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in a storeroom function, so a single part number can be set to either electrically locked or electrically unlocked in the field. The ML20914-DS instead has the mode chosen at order time, Fail Safe or Fail Secure, along with handing and whether request to exit monitoring is included. If the electrical mode may change after install, the field selectable ML190 handles that; if the opening is defined and you want the Corbin Russwin keyway and trim family, stay with the ML20914.
12) We want credential readers at the door rather than running wire back to a panel. What should we look at instead of the ML20914-DS?
Reader-at-the-door mortise locks in the same Grade 1 class include the TownSteel FME-2000 Series, a heavy duty Grade 1 classroom mortise lockset with RFID for a 1-3/4 inch door, and the Schlage LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. Dormakaba's E-Plex E5086 is a Grade 1 pushbutton and card mortise lock in a back-to-back configuration. The ML20914-DS carries no reader of its own; it is a wired electrified lever lockset whose outside lever is released by the access system, available with request to exit monitoring.
13) Should I choose rose or escutcheon trim on the ML20914 mortise lock?
Three trims are offered: A rose, and M or N escutcheon. Rose trim is the smaller footprint and reads cleaner on a narrow-ish face; escutcheon covers more of the door and is the usual pick when you're covering old trim marks or want the taller plate look across a corridor. Spacing is fixed either way, center to center lever to cylinder is 3-5/8 inches and lever to thumbturn is 2-7/16 inches. All trim designs are thru-bolted for alignment. The lever on this one is the DS Dirke cast lever, in 625 bright chrome or 626 satin chrome.
14) How does the Corbin Russwin ML20914 compare to a Schlage L9092EU electrified mortise lock?
They cover the same job, an electrified mortise lock with access control monitoring on a 1-3/4 inch commercial door. The Schlage 03A electric lock/unlock outside lever mortise lock we carry is keyed outside with request to exit and runs 12/24VDC, heavy duty, corridor function. The ML20914 is the Corbin Russwin route: Grade 1 to A156.13 Series 1000, 2-3/4 inch backset, ordered as either Fail Safe or Fail Secure with RX optional. The deciding factor is usually the keyway you already run in the building and which brand's trim the rest of your openings wear.
15) Is the ML20914 durable enough for a high-traffic entrance in a hospital or school?
It is built for that. The lock case is heavy-gauge steel and the lockset is tested to 14.5 million cycles under UL, well past the A156.13 Grade 1 requirement it is certified to. The anti-friction two-piece latchbolt takes less force to close, which matters on a door with a closer that gets hit thousands of times a week. Corbin Russwin lists it for commercial office, healthcare, education, government, retail, industrial, and multi-tenant residential use.
16) What mortise locks look like the ML20914-DS but will not work on an access controlled opening?
Several mortise parts share the form factor without doing the same job. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for a 1-3/4 inch door, and the Falcon MA101 is a Grade 1 heavy duty passage function mortise lock, field reversible, with a fire rating; neither locks. The Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset, and the Schlage L0170 is a half dummy trim with no latch at all. The ML20914-DS is an electrified keyed lever lockset ordered Fail Safe or Fail Secure with a 6-pin L4 keyway cylinder, less cylinder, or IC less core.
17) Our doors are thinner than 1-3/4 inches. What mortise lock works there instead of the ML20914-DS?
The ML20914-DS is specified for a 1-3/4 inch door on a 2-3/4 inch backset. For thinner leaves, the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 classroom electronic mortise lock rated for doors 1-5/8 to 1-7/8 inches with a weatherproof design, and the DL4500 Series is a Grade 1 electronic mortise deadbolt over the same 1-5/8 to 1-7/8 inch range with 2,000 user codes. Those are standalone keypad units rather than panel-wired locks, so confirm the opening does not require central control before substituting.
18) For a behavioral health or ligature resistant opening, what should we specify instead of the ML20914-DS with the Dirke lever?
The TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function for a 1-3/4 inch door, the MRX-A-01 is the same passage function in a 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 in satin stainless steel. The ML20914-DS is furnished with the cast Dirke lever in bright chrome or satin chrome, which is a conventional lever profile rather than an anti-ligature one.
19) Is a Grade 2 electronic mortise lock like the Schlage LEBMB an alternative to the ML20914-DS?
They sit at different levels. The Schlage LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions on a 1-3/4 inch door with a 3 hour fire rating. The Corbin Russwin ML20914-DS is built to ANSI/BHMA A156.13 Series 1000 Grade 1 for commercial openings and is a wired electrified lockset rather than a credential-reading one. For multi-family unit doors the LEBMB gives mobile credentials at the leaf; for a Grade 1 commercial opening tied into an access panel, the ML20914 is the match.
20) For a classroom security opening, what should we consider alongside the ML20914-DS?
Classroom-function mortise options include the Cal-Royal NM8070, a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch for a 1-3/4 inch door, the Marks USA LA318GJ Grade 1 classroom security indicator lockset with an ANSI strike and steel escutcheon for a 1-3/4 inch door, and the TownSteel FME-4000 Series, a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID. The ML20914-DS is a Grade 1 electrified lockset controlled from the access system in Fail Safe or Fail Secure mode, which is the approach when lockdown is initiated centrally rather than at the door.
21) We only need a mortise lock body, not a complete electrified lockset. What are the options?
The BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA Series is a heavy duty mortise lockbody with intruder function. Baldwin's 6301 and 6310 are entrance/apartment and entrance/storeroom mortise lock bodies on a 2-1/2 inch backset. The Corbin Russwin ML20914-DS ships as a complete electrified lever lockset on a 2-3/4 inch backset, with the Dirke lever and rose or escutcheon trim selected at order.
