Corbin Russwin ML20907-NSA-626-SAF – Frequently Asked Questions

1) Do I have to order the ML20907 as fail safe or fail secure, or can I switch it in the field?
You pick it at the order. The ML20907 electrified mortise lockset is built either Fail Safe (lever unlocks when power drops) or Fail Secure (lever stays locked when power drops), and that choice is a separate orderable configuration, not a field setting. Life safety egress routes and stair returns normally go fail safe; most secured perimeter and tenant doors go fail secure. Get the function right against your access control drawing before the order goes in.
2) Does the Corbin Russwin ML20907 come with request-to-exit monitoring?
Only if you order it that way. Request to Exit monitoring is a yes/no option on the ML20907, so the same lock is sold with or without the RX switch. If your access control panel needs a signal when the inside lever is turned, to shunt an alarm or release a door position contact, order the RX version. Adding it later means changing the lock body, not adding a part to the trim.
3) Will this mortise lock fit my existing 2-3/4 inch backset prep on a 1-3/4 inch commercial door?
It will. The ML20907 uses the standard 2-3/4 inch backset and a 1-3/4 inch door thickness, which is the normal commercial mortise prep. The lock case is heavy gauge steel at 5-7/8 x 4 x 15/16 inches, and the armored front measures 8 x 1-1/4 inches, so it drops into a standard ANSI mortise pocket. Door thicknesses from 1-3/8 inch up to 4 inches are accommodated with the optional thickness builds.
4) This is a no-cylinder lockset. What cylinder do I need to add?
The ML20907 ships without a cylinder, so you supply it. It works with new or existing Corbin Russwin key systems and will also accept most other manufacturers' cylinders, which is what lets it drop into a building already keyed to another brand. The Corbin Russwin standard is a brass 6-pin L4 keyway, 0-bitted. Order the cylinder, cam and keying alongside the lock, because the lockset alone will not operate keyed.
5) Can I use this electrified mortise lock on a 3-hour fire rated door?
Yes. The ML20907 is UL and cUL listed to UL10C positive pressure for fire doors rated up to and including 3 hours, on single doors up to 4 by 10 feet and pairs up to 8 by 10 feet. It is also ADA compliant under A117.1 and certified to ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1. If you specify fail safe on a fire door, confirm the release scheme against your fire alarm interface, since the lever unlocks on power loss.
6) Will the ML20907 latch into the strike already in my frame?
The lock uses a 3/4 inch throw two-piece anti-friction latchbolt with a 9/16 inch effective deadlocking auxiliary latch, and ships with an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already has a standard ANSI mortise strike cutout, it lines up. If the existing strike lip to center is different from 1-1/8 inch, use the strike supplied rather than the old one or the latch will not seat cleanly.
7) What should I use instead of the ML20907 on an opening that has no access control wiring?
For a mechanical opening, Grade 1 mortise locksets such as the Accentra 8805FL storeroom lock with Arcadia lever, the Cal-Royal NM8080 storeroom lockset with interchangeable core option, or the Sargent 7925 dormitory exit function lock with rose trim and single cylinder deadbolt work without power. The Corbin Russwin ML20907 is an electrified mortise lockset built around Fail Safe or Fail Secure operation, so it expects a power supply at the opening.
8) Is a standalone keypad mortise lock a substitute for the ML20907?
Not for the same job. Standalone credential locks such as the Alarm Lock DL3500CR Trilogy Grade 1 classroom mortise lock with 300 user codes, the Schlage CO-100 standalone electronic mortise lock with keypad reader, or the BEST 45HZ EZ Series keypad mortise lock with key override make the access decision at the door. The Corbin Russwin ML20907 has no reader of its own; it is a Fail Safe or Fail Secure electrified lockset driven by a separate access control system, with request-to-exit monitoring available.
9) Is the Dormakaba Saffire LX-I-M002 an equivalent electronic mortise lockset?
The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Schlage LEBMB-ADD mobile-enabled mortise lock is also Grade 2 for privacy, office and apartment functions on 1-3/4 inch doors. The Corbin Russwin ML20907 is an ANSI/BHMA Grade 1 mortise lockset wired for Fail Safe or Fail Secure operation, which is the difference to weigh if your spec calls out Grade 1.
10) Do I need to specify handing when I order this Corbin Russwin lockset?
The lock is handed, but the latchbolt is quick reversible, so it can be re-handed in the field without opening the lock case. That matters on a multi-door job where the openings are mixed or someone measured the swing wrong: one lock covers either hand. You still need the lever and trim oriented correctly for the opening.
11) What lever and trim choices do I get, and will they match the other doors in my building?
The lever is the NS Newport cast design, and it comes in four finishes: 612 satin bronze, 613 satin bronze oil-rubbed, 626 satin chrome, and 630 satin stainless steel. Trim mounts either on a rose (A or B) or on an escutcheon (M or N). For a facility standardizing on one look, 626 and 630 are the usual commercial pair. The trim is thru-bolted, which keeps the two sides aligned and makes the lever harder to pull off.
12) What is the difference between this and a standalone electronic mortise lock like the Schlage CO-100 or TownSteel FME-2000?
Different animals. The ML20907 is a wired electrified lock with no reader and no credential logic of its own: it takes power and a signal from an access control panel, and it can report door use back through the optional RX switch. Standalone units such as the Schlage CO-100 Grade 1 mortise lock with keypad reader or the TownSteel FME-2000 Grade 1 classroom mortise lockset with RFID carry the credential reader and user database on the door itself, with no panel and no wiring run. Pick the electrified lock when the opening is already on a panel; pick a standalone when running wire to the door is not practical.
13) Is there an equivalent electrified mortise lock from another brand if I'm standardized on Schlage?
The closest peer we carry is the Schlage L9092EU with 03A trim, an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, on 1-3/4 inch doors. Command Access also makes the ML190 Series motorized mortise lock, heavy duty storeroom function, with field selectable EL/EU operation on 24VDC, which is worth a look if you want one part number to cover both fail safe and fail secure. The Corbin Russwin ML20907 differs in that fail safe or fail secure is fixed at order.
14) Is this lock heavy duty enough for a school corridor or hospital door that gets hammered all day?
It is built for exactly that. The lock case is heavy gauge steel, certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, and UL cycle tested to 14.5 million cycles. The anti-friction two-piece latchbolt takes less force to close, which helps on doors with strong closers. Corbin Russwin lists it for commercial offices, healthcare, education, government, industrial, multi-tenant residential and retail.
15) Does this ML2000 lock have a deadbolt, and how far does it throw?
The ML2000 lock body carries a one-piece stainless steel deadbolt measuring 19/32 by 1-1/4 inches with a 1 inch throw, alongside the 3/4 inch latchbolt. Spacing from lever to cylinder is 3-5/8 inches center to center and lever to thumbturn is 2-7/16 inches, so if you are matching an existing mortise prep with a cylinder or turn hole already drilled, check those two dimensions before you commit.
16) What is a wireless alternative if I do not want to run wire to the door?
Wireless and credential-based mortise options include the Schlage Electronics LEMD-GRW Grade 1 ENGAGE Series wireless mortise lock with 125kHz proximity reader and 3-hour fire rating, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock for Adams Rite deadlatches, and the TownSteel FME-2000 Series Grade 1 classroom mortise lockset with RFID. The Corbin Russwin ML20907 is a wired electrified lockset ordered as Fail Safe or Fail Secure.
17) I only need to replace the mortise lock body, not the whole lockset. What are my options?
Lock-body-only items include the BEST 45HCA public entrance mortise lock body with field reversible operation and the BEST 45HCA intruder function lockbody, both heavy duty, plus the Baldwin 6310 entry/storeroom mortise lock body on a 2-1/2 inch backset for doors 1-3/8 inch and over. The Corbin Russwin ML20907 is supplied as a complete electrified lockset with Newport cast lever trim on a 2-3/4 inch backset, so it is a different order if all you need is a case.
18) What mortise lock should I use for a classroom or intruder-function opening rather than the ML20907?
For classroom security, the Marks USA LA318GJ classroom security indicator mortise lockset with ANSI strike and steel escutcheon, the Cal-Royal NM8070 Grade 1 classroom lockset with auxiliary deadlatch, and the TownSteel FME-4000 Series electronic intruder classroom mortise lockset all cover 1-3/4 inch doors. The Corbin Russwin ML20907 is configured as Fail Safe or Fail Secure for access control rather than as a keyed classroom function.
19) Is the Dormakaba E-Plex E5086 a comparable Grade 1 mortise option?
The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card lock in a back-to-back mortise configuration, so credentials are presented at the lock itself. The Corbin Russwin ML20907 instead ties into a building access control system through Fail Safe or Fail Secure electrification, with request-to-exit monitoring offered, and carries Newport cast lever trim.
20) For a behavioral health opening, is the ML20907 the right mortise lock or is there a better fit?
For ligature-resistant openings, the TownSteel MRX-L-01 Grade 1 heavy duty anti-ligature lever mortise lockset in passage function, the TownSteel MRX-A-01 ligature resistant arch trim lockset, and the Marks USA 5PDN Grade 1 hospital passage push/pull paddleset are purpose-built, all on 1-3/4 inch doors for the TownSteel units. The Corbin Russwin ML20907 is offered with the Newport cast lever on rose or escutcheon trim.
21) What looks like a substitute for an electrified mortise lockset but is not?
Several mortise-family items do not secure an access controlled opening: the Sargent 130KB and 130W mortise thumbturns are trim pieces only, the Schlage L0170 is half dummy trim in a non-keyed Grade 1 mortise lever, and the Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function. The Corbin Russwin ML20907 is a working electrified lockset in Fail Safe or Fail Secure with a 3/4 inch latchbolt and ANSI straight lip strike.
22) My door is 1-5/8 to 1-7/8 inch. Does the ML20907 fit, or should I look at something else?
The Corbin Russwin ML20907 is listed for 1-3/4 inch doors with a 2-3/4 inch backset. Alarm Lock Trilogy mortise locks including the DL2700CR classroom, the DL3500CR classroom, and the DL4500 electronic mortise deadbolt are specified for a 1-5/8 to 1-7/8 inch door thickness range if you need that spread on one part number.
23) What is a simpler mortise option for interior doors that do not need to lock at all?
Non-keyed mortise options include the Schlage PM010 Grade 1 passage latch mortise lock, the Falcon MA101 Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating, and the Hager 3810S Grade 1 passage mortise lock with rose on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors. The Corbin Russwin ML20907 is an electrified Fail Safe or Fail Secure lockset and shares the 2-3/4 inch backset.
