Corbin Russwin ML20915-NSA-626-SAF – Frequently Asked Questions

1) What is the difference between the fail safe and fail secure versions of the Corbin Russwin ML20915?
The ML20915 is ordered either way. Fail safe (SAF) locks both grips when energized, so cutting power unlocks the door for free egress and entry, which is what you want on a stair or a door tied into a fire alarm release. Fail secure (SEC) locks both grips when de-energized, so the door stays locked in a power loss and the access control system energizes it to allow entry. Same lock body, same trim, different electrical behavior, so pick the one your access control drawing calls out.
2) Will the ML20915 electrified mortise lock fit a standard 1-3/4 inch commercial door?
Yes. The ML20915 is set up for a 1-3/4 inch door with a 2-3/4 inch backset, which is the standard commercial mortise prep. The lock case itself measures 5-7/8 x 4 x 15/16 inches and the armored front is 8 x 1-1/4 inches, so it drops into an existing ANSI mortise pocket cut to those dimensions.
3) Do I have to order the ML20915 handed, or can I re-hand it in the field?
It ships handed but it is field reversible. The ML2000 uses a quick reversible latchbolt, so you re-hand it without opening the lock case. That matters if you are stocking spares across a building and do not want two part numbers on the shelf.
4) Can I use the Corbin Russwin ML20915 on a fire rated door?
Yes. The ML20915 is UL/cUL listed and UL10C positive pressure rated, good for fire doors up to and including a 3-hour rating, covering a single door up to 4 x 10 feet or a pair up to 8 x 10 feet. It is also ADA A117.1 compliant and carries California State Fire Marshal and windstorm/hurricane certification.
5) What does No Cylinder Override mean on the ML20915, and should I be worried about lockout?
No cylinder override means there is no key cylinder to mechanically bypass the electrified function. Both grips are controlled by the access control system only. If your facility needs a key to get in when the system is down, this is the wrong function code and you want an electrified mortise with a cylinder override instead. It is a common choice where the security policy is that credentials are the only way through the door.
6) Will the ML20915 latch into my existing ANSI strike?
It should. The standard latch is a 3/4 inch throw two-piece anti-friction latchbolt with a 9/16 inch deadlocking auxiliary latch, and the supplied strike is an ANSI straight lip at 1-1/8 inch lip to center, 4-7/8 x 1-1/4 inches. If your frame already has a standard ANSI mortise strike prep with the same lip-to-center, the latch lines up. Check the lip projection against your frame reveal, because a short lip will drag the latch.
7) What do I need to specify when ordering a Corbin Russwin ML20915?
Five things. Function, fail safe or fail secure. Whether you want request-to-exit monitoring built in, which is a yes or no option. Trim style, either a rose (A or B) or an escutcheon (M or N). Lever style, which on this configuration is the NS Newport cast lever. And finish: 612 satin bronze, 613 satin bronze oil-rubbed, 626 satin chrome, or 630 satin stainless steel. Handing you can sort out on site since the latch reverses.
8) What is the closest equivalent to the Corbin Russwin ML20915 from another manufacturer for an access-controlled opening with request-to-exit monitoring?
The Schlage L9092EU electrified mortise lock, ordered as the 03A trim version with request to exit (RX) and 12/24VDC operation, is the closest cross-brand counterpart. It is a heavy duty corridor-function mortise lock for 1-3/4 inch doors. The ML20915 is also built for a 1-3/4 inch door with a 2-3/4 inch backset and is offered in both Fail Safe and Fail Secure configurations with request-to-exit monitoring as an ordering choice. The main difference in function is that the Schlage electrifies the outside lever and is keyed outside, while the ML20915 is a no cylinder override, both-grips-lock design.
9) Is there an electrified mortise lock with field-selectable fail safe or fail secure operation instead of choosing one at order time?
Yes. The Command Access ML190 series motorized mortise lock is a heavy-duty storeroom-function mortise lock with field selectable EL/EU operation on 24VDC, so the same lock body can be set either way after it arrives. With the Corbin Russwin ML20915, Fail Safe and Fail Secure are selected as separate configurations when you order, and the ML20915 is a no cylinder override design where both grips lock.
10) If the opening has no access control wiring, what mechanical mortise lock can be used instead of the Corbin Russwin ML20915?
The ML20915 is an electrified mortise lockset requiring Fail Safe or Fail Secure power. For a purely mechanical opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. Both are keyed mechanical locks with no wiring run to the door.
11) For a classroom or lockdown application, is the ML20915 the right mortise lock or is there something more suitable?
The ML20915 is a no cylinder override, both-grips-lock electrified lockset, meaning under the locked state neither lever retracts the latch and there is no key override at that trim. Where staff need to secure the door from inside the room, a classroom or intruder function is the more usual choice: the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an ANSI strike and steel escutcheon 8-1/2 inch by 2-3/4 inch by 7/16 inch, and the TownSteel FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID.
12) My door is 1-5/8 inch thick. Can I still use the Corbin Russwin ML20915?
The ML20915 is specified for a 1-3/4 inch door. If the leaf is thinner, the Alarm Lock Trilogy electronic mortise locks cover a 1-5/8 to 1-7/8 inch range: the DL2700CR is a Grade 1 classroom-function lock with weatherproof design, the DL3500CR is a Grade 1 classroom lock with 300 user codes, and the DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad. These are keypad locks rather than wired electrified locksets, so confirm the function you need before switching.
13) I need a Grade 1 mortise lock but the Dormakaba Saffire RFID lockset was suggested. How do the grades compare?
The Dormakaba LX-I-M002 Saffire electronic RFID mortise lockset with BLE mobile access is a BHMA Grade 2 electronic mortise lockset. The Corbin Russwin ML20915 is certified to ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1. If the specification on the drawing calls for Grade 1, the Saffire will not meet it on that line.
14) Is there a mortise lock with key override if the no cylinder override function on the ML20915 does not suit the opening?
Yes. The BEST 45HZ EZ series is an electronic keypad mortise lock with a key override function, and the Accentra NTM623-NR nexTouch Generation 3 mortise lock with capacitive touchscreen keypad is a Grade 1 no-deadbolt model with cylinder override. The Corbin Russwin ML20915 is specifically the no cylinder override, both grips lock version of the ML2000 electrified family, so if a mechanical key path through the lock is required, one of those is the better fit.
15) Do I need a separate request-to-exit sensor above the door with this lock?
Not if you order the RX option. The ML20915 can be built with request-to-exit monitoring in the lock, so turning the inside lever signals the access control panel that a legitimate exit occurred and the door alarm shunts. Ordered without it, you will need a separate REX device such as a motion sensor to keep the panel from reading the opening as a forced door.
16) Is the ML20915 heavy enough for a high traffic entrance in a school or hospital?
It is built for exactly that. Heavy-gauge steel lock case, certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, and UL cycle tested to 14.5 million cycles. The trim is thru-bolted, which keeps the levers aligned and makes them harder to pull off. That is the top mechanical tier for a mortise lock.
17) How does the ML20915 compare to a Schlage electrified mortise lock for the same opening?
Closest cross-brand equivalent we carry is the Schlage L9092EU with 03A trim, an electric lock/unlock outside lever mortise lock with request-to-exit, 12/24VDC, heavy duty, listed for a 1-3/4 inch door. Key difference: the Schlage is keyed outside, so it has a mechanical key override. The ML20915 has no cylinder override and controls both grips electrically. If a master key has to work the door when the network is down, the Schlage arrangement fits; if you want credential-only access, the Corbin Russwin does.
18) I want a keypad or card reader on the door instead of wiring back to a panel. What should I look at instead of the ML20915?
The ML20915 is a wired electrified lock, it needs power and an access control system behind it. For a standalone or wireless opening, look at the Schlage LEMD-GRW, a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3-hour fire rating; the TownSteel FME-2000, a Grade 1 classroom mortise lockset with RFID; or the Dormakaba E-Plex 5086, a Grade 1 pushbutton and card mortise lock. Those put the credential reader on the lock itself and skip the head-end wiring.
19) I need credential-based access at the door rather than a wired electrified lock. What mortise options are there?
Standalone and networked electronic mortise locks handle the credential at the door instead of from a panel. The Alarm Lock DL3500CR Trilogy is a Grade 1 classroom-function electronic mortise lock with 300 user codes for 1-5/8 to 1-7/8 inch doors, the Schlage CO-100-MS is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader for 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 ML20915 has no reader of its own; it is a wired electrified lockset that takes its lock and unlock command from the access control system.
20) Is the BEST 45HW a substitute for the Corbin Russwin ML20915?
The BEST 45HW is the nearest same-category alternative: a wired electromechanical heavy duty mortise lock with 12V/24V operation, so it serves the same access-controlled opening. The differences that matter when swapping are the trim and keying families. The ML20915 uses Corbin Russwin ML2000 trim, comes with the Newport cast lever, and is offered with A or B rose and M or N escutcheon trim in 612, 613, 626 and 630 finishes, with request-to-exit monitoring available. Door prep and cylinder or core selection follow each manufacturer's own system, so verify both before treating one as a drop-in for the other.
21) Will a BEST 45H mortise lock body work in place of the Corbin Russwin ML20915?
No, they are not interchangeable in purpose. The BEST 45H is a heavy duty public entrance function mortise lock body with field reversible operation, and the 45HCA intruder-function body is a mechanical lock body as well. The ML20915 is an electrified mortise lockset with Fail Safe or Fail Secure operation that has to be energized to do its job. If your specification calls for the door to lock or unlock on a signal from an access control system, a mechanical lock body will not satisfy it.
22) What mortise lock should I use for an interior door that only needs to latch, not lock?
For a non-keyed latching opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset. The Corbin Russwin ML20915 locks both grips under power and is intended for controlled openings, so it is more lock than a plain passage door needs.
23) Does the Schlage LE series wireless mortise lock match the grade of the Corbin Russwin ML20915?
It depends which LE lock. The Schlage LEMD-GRW ENGAGE series wireless mortise lock with a 125kHz proximity reader is Grade 1 with a 3 hour fire rating, while the Schlage LEBMB-ADD mobile-enabled mortise lock with push button and LED is Grade 2 for 1-3/4 inch doors with a 3 hour fire rating. The Corbin Russwin ML20915 is certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and is rated for fire doors up to and including 3 hours, so on grade it lines up with the LEMD rather than the LEBMB.
24) Can I use a Baldwin 6310 mortise lock body on the same doors as the Corbin Russwin ML20915?
Not without changing the door prep. The Baldwin 6310 entrance/storeroom mortise lock body uses a 2-1/2 inch backset and is listed for 1-3/8 inch doors and over, and the 6301 entry/apartment body is also a 2-1/2 inch backset. The Corbin Russwin ML20915 is built to a 2-3/4 inch backset on a 1-3/4 inch door, so the lever and cylinder locations differ. The Baldwin bodies are also mechanical, with no fail safe or fail secure electrified operation.
25) Is there a dormitory or corridor function mortise lock with a deadbolt as an alternative to the ML20915?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock from the 7900 series with rose trim and a single cylinder deadbolt, which suits a corridor or dorm door secured by key and thumbturn rather than by an access control signal. The Corbin Russwin ML20915 is an electrified ML2000 lockset in Fail Safe or Fail Secure form with no cylinder override, so the two answer different security schemes on the same type of opening.
26) For a behavioral health or anti-ligature opening, should I specify the ML20915 or a different mortise lockset?
For anti-ligature openings, 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 and ADA compliant in satin stainless steel. The Corbin Russwin ML20915 ships with the Newport cast lever, which is a conventional lever profile.
27) Is the Dormakaba E-Plex or PowerPlex mortise lock comparable to the Corbin Russwin ML20915?
They sit in the same opening but work differently. The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card lock in a back-to-back mortise configuration, the E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile applications, and the PowerPlex P2066 is a mortise lock from the PowerPlex 2000 series. All carry their credential reader on the lock. The Corbin Russwin ML20915 has no keypad or card reader and no cylinder override; it locks both grips on a Fail Safe or Fail Secure power scheme driven by the access control system, with request-to-exit monitoring available.
28) Can I use a Schlage PC10 cylindrical lock where an ML20915 is specified?
No. The Schlage PC10 is a Grade 1 passage cylindrical lock with a rose for 1-3/4 inch doors, and a cylindrical lock uses a bored door prep rather than a mortise pocket. The Corbin Russwin ML20915 is a mortise lockset needing a mortised lock case in the door edge, and it is field reversible for handing. Converting an opening between the two prep types is a door change, not a hardware swap.
29) For an office or entrance door that does not need electrification, what Grade 1 mortise lockset compares with the ML20915?
The Cal-Royal NM8050 is a Grade 1 heavy duty office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inch. Both share the 1-3/4 inch door and mortise prep the Corbin Russwin ML20915 is built for, but neither carries the Fail Safe or Fail Secure electrified operation or request-to-exit monitoring.
30) What should I use for a restroom or bedroom door rather than the ML20915?
Privacy function is the usual call there. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for 1-3/4 to 2 inch doors, and the Schlage CO-100-MS in privacy function is a Grade 1 heavy duty standalone electronic mortise lock with keypad reader for 1-3/4 inch doors. The Corbin Russwin ML20915 locks both grips under an access control signal, which is not how a privacy door is meant to behave.
31) Can I key this into the Corbin Russwin system already in my building?
Yes, the ML2000 works with new or existing Corbin Russwin key systems, and the line accepts most other manufacturers' cylinders. Standard cylinder for the series is brass, 6-pin L4 keyway, 0-bitted. Note that the ML20915 function itself is a no-cylinder-override configuration, so keying matters only if you are standardizing other ML2000 functions on the same doors or floor.
32) Do I have to buy a different lock body if a door needs a different function later?
No. The ML2000 lock body is multi-function, with 12 functions configurable from a single ML2054 lock body, so a facility can carry fewer spares and change a door's behavior without replacing the case. Electrified configurations like the ML20915 also offer motorized electric latch retraction (MELR) within the ML20900 series if an opening later needs latch retraction for automatic operators.
33) Which finishes does the Newport lever version of the ML20915 come in, and will it match my existing hardware?
Four finishes: 612 satin bronze, 613 satin bronze oil-rubbed, 626 satin chrome, and 630 satin stainless steel. 626 is the usual match for satin chrome commercial trim and 630 for stainless push plates and exit devices. The lever itself is the NS Newport cast design, available with either rose trim (A or B) or escutcheon trim (M or N), so pick the escutcheon if the doors it is joining already run escutcheon plates.
34) Will a Sargent 130KB thumbturn or a Sargent 4874 deadbolt substitute for the ML20915?
No. The Sargent 130KB is a standard duty mortise thumbturn from the 8200 series and the 130W is a mortise thumbturn with a round backplate, both trim items rather than locksets. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch or lever operation. The Corbin Russwin ML20915 is a complete electrified mortise lever lockset with a 3/4 inch latchbolt and an ANSI straight lip strike, 1-1/8 inch lip to center, supplied with Newport cast levers.
35) Is a Schlage L0170 half dummy trim or a Falcon MESC600DT the same thing as an ML20915 lever trim?
No. The Schlage L0170 is a half dummy trim, a Grade 1 heavy duty non-keyed mortise lever with dummy function for 1-3/4 inch doors, and the Falcon MESC600DT is a dummy escutcheon lever trim for M9900 series exit devices with a fire rating. Neither operates a latch. The Corbin Russwin ML20915 trim is part of a working electrified lockset and is offered with A or B rose and M or N escutcheon in 612 satin bronze, 613 satin bronze oil-rubbed, 626 satin chrome and 630 satin stainless steel.
36) Would a Kaba Ilco 185 mortise deadbolt or a Marks USA 21AC ornamental iron lock work in place of the ML20915?
They are not equivalents. The Kaba Ilco 185 series is a no-handing mortise deadbolt, which secures but does not latch or provide lever operation. The Marks USA 21AC and 22AC entrance double cylinder ornamental iron mortise locks with round knob are listed for 1 inch doors, far thinner than the 1-3/4 inch door the Corbin Russwin ML20915 is built for, and they are knob rather than lever trim.
