Corbin Russwin ML20932-PSA-626-SAF – Frequently Asked Questions

1) What does the ML20932 mortise lock actually do on the door, and when does it lock or unlock?
The Corbin Russwin ML20932 is a double cylinder, both-grips-lock electrified mortise lockset: both levers are locked and a key is required from either side. It is ordered as either Fail Safe or Fail Secure. Fail Safe unlocks when power drops, which is what you use on a stair or egress-critical opening tied to fire alarm release. Fail Secure stays locked without power, which is the normal choice for a secured tenant or storeroom door on access control.
2) Will this Corbin Russwin electrified mortise lock fit a 1-3/4 inch commercial door with a 2-3/4 inch backset?
Yes. The ML20932 is built for a standard 1-3/4 inch door with a 2-3/4 inch backset, which is the standard commercial mortise prep. Thicker doors up to 4 inches are handled with optional thickness parts, and the lock case itself measures 5-7/8 x 4 x 15/16 inches.
3) Do I have to specify handing when I order the ML20932, or can it be reversed in the field?
It is a handed lock, but the ML2000 latchbolt is quick reversible, so the handing can be changed in the field without opening the lock case. Useful when a door gets swapped or the wrong hand shows up on the job.
4) Will the ML20932 latch into the strike already in my frame?
The standard latch is a two-piece anti-friction latchbolt with a 3/4 inch throw, backed by a 9/16 inch deadlocking auxiliary latch, and the deadbolt throws a full 1 inch. It 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 prep, it drops in; if the existing strike lip is a different lip-to-center for the jamb condition, order the matching strike.
5) Can I key this lock into my existing master key system, or do I have to order cylinders separately?
Keying is a choice at order time: a conventional 6-pin cylinder in the L4 keyway, an L4 keyway option, an interchangeable core prep supplied less core, or less cylinder entirely so you can fit your own. The conventional cylinder ships 0-bitted. It works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so an IC house can keep its own cores. Remember it is double cylinder, so you need two.
6) Is this mortise lockset approved for a fire-rated opening?
Yes. The ML20932 is UL and cUL listed with UL10C positive pressure, rated for 3-hour fire doors up to 4 by 10 feet single or 8 by 10 feet pair. It also meets ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and ADA A117.1, and carries California State Fire Marshal and windstorm/hurricane certification.
7) Does this lock give a request-to-exit signal back to my access control panel?
Request to exit monitoring is an option you select when ordering the ML20932, yes or no. If your panel needs an RX contact to shunt an alarm or log free egress from the inside lever, specify the RX version; the standard build without it just takes the power input for fail safe or fail secure operation.
8) What is the closest cross-brand equivalent to the Corbin Russwin ML20932 electrified mortise lockset for an access-control opening with request-to-exit monitoring?
The nearest peer is the Schlage L9092EU electric lock/unlock outside lever mortise lock with keyed outside and request-to-exit monitoring, rated for 12/24VDC on a 1-3/4 inch door in a heavy duty corridor function. The ML20932 is a double cylinder, both-grips-lock electrified mortise lockset configurable as Fail Safe or Fail Secure, with request-to-exit monitoring offered as an option and a 2-3/4 inch backset on a 1-3/4 inch door. Both are electrified mortise bodies intended to be tied into an access control platform; the Schlage electrifies the outside lever on a corridor function, while the ML20932 locks both grips through two cylinders.
9) Is there a field-selectable electrified mortise lock alternative if I need to choose fail safe or fail secure after the lock is on site?
The Command Access ML190 Series motorized mortise lock, part CAT-ML19092-M, is a heavy-duty storeroom-function body with field selectable EL/EU operation running on 24VDC, so the electrical mode is set during installation. The Corbin Russwin ML20932 covers both modes as well, but the mode is chosen at order time as either Fail Safe or Fail Secure. If your submittal needs one part number that can be flipped either way in the field, the ML190 is the one to look at; if the mode is fixed per opening on the drawings, the ML20932 ships configured.
10) If the opening does not have power at the door, what mechanical mortise lock should I use instead of the ML20932?
Without a power transfer, an electrified lock is the wrong choice and a keyed mechanical mortise body is the substitute. For a keyed-outside application, the Accentra 8805FL is a Grade 1 storeroom mortise lock in 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. The Corbin Russwin ML20932 is specifically an electrified Fail Safe/Fail Secure lockset built to tie into access control, so it needs door power to do its job.
11) Can I use a standalone battery keypad mortise lock instead of the ML20932 if I do not want to run wire to the door?
Yes, that is the usual trade. Standalone options include the Schlage CO-100-MS-40-KP, a Grade 1 heavy duty electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors; the Alarm Lock DL3500CR Trilogy, a Grade 1 classroom-function electronic mortise lock holding 300 user codes for doors 1-5/8 to 1-7/8 inch; and the BEST 45HZ EZ Series electronic keypad mortise lock with key override. These manage credentials at the lock. The Corbin Russwin ML20932 instead takes its lock and unlock command from an access control panel over its Fail Safe or Fail Secure electrical function, with request-to-exit monitoring available, so door position and egress signals report back to the head end.
12) Which mortise products look like substitutes for the ML20932 but will not work on an electrified access control opening?
Several mortise parts sit adjacent but do not do the same job. The Schlage PM010 and Falcon MA101 are Grade 1 passage mortise locks, non-keyed and always free on both sides. The Hager 3810S and 3810E are Grade 1 passage mortise locks with a 2-3/4 inch backset in rose and escutcheon versions. The Schlage L0170 is a half dummy trim with no latch at all, and the Sargent 130KB and 130W are mortise thumbturns, not locks. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which is keyed both sides but has no latchbolt or lever. The Corbin Russwin ML20932 is a latching, double cylinder electrified lever lockset with a 3/4 inch latchbolt and Fail Safe or Fail Secure operation.
13) What trim and finish does the ML20932-PS come in, and do I get rose or escutcheon?
Trim is the Princeton cast lever (PS) in 626 satin chrome. You pick the mounting style at order: A or B rose, or M or N escutcheon. Trim is thru-bolted for alignment and security. Center-to-center from lever to cylinder is 3-5/8 inches and lever to thumbturn is 2-7/16 inches, which is what to check against existing door prep if you are matching other openings in the building.
14) Is an electrified mortise lock the right choice, or should I use a standalone keypad or credential lock instead?
An electrified mortise lock like the ML20932 is wired back to an access control panel, so it belongs where you already have a head-end, power supply and credential readers, and where you need fail safe release tied to alarm. If there is no panel to wire into, a standalone lock makes more sense: the Schlage CO-100 standalone electronic mortise lock or the TownSteel FME-2000 Grade 1 mortise lockset with RFID both put the credential at the door. For a wireless networked middle ground, the Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock.
15) What is the closest electrified mortise lock from another brand if I am standardized on something other than Corbin Russwin?
Two direct wired equivalents: the Schlage L9092EU with 03A trim, an electric lock/unlock outside lever mortise lock with request-to-exit and 12/24VDC, prepped for 1-3/4 inch doors, and the BEST 45HW wired electromechanical mortise lock, heavy duty, 12V/24V. If you are retrofitting a lock body into an existing mortise pocket rather than buying a complete set, the Command Access ML190 motorized mortise lock is field selectable between EL and EU on 24VDC.
16) Is the ML20932 heavy enough for a high-traffic entrance that gets abused all day?
The lock case is heavy-gauge steel and the set is certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, with UL cycle testing verified at 14.5 million cycles. The deadbolt is one-piece stainless. Grade 1 is the top commercial tier, which is what you want on school, hospital and office entrances rather than Grade 2 hardware.
17) I only need a mechanical mortise lock, not an electrified one. What should I look at instead?
If there is no access control on the opening, skip the electrified ML20932 and buy a mechanical lockset by function. Storeroom: Accentra 8805FL Grade 1 with Arcadia lever, or Cal-Royal NM8080. Classroom: Cal-Royal NM8070. Office/entrance: Cal-Royal NM8050. Passage: Falcon MA101 Grade 1 heavy duty, field reversible. The Cal-Royal bodies are listed for 1-3/4 inch doors, same as the ML20932.
18) What wireless or credential-reader mortise lock competes with the ML20932 for a hotel or dorm rollout?
Credential-reader mortise options include the Schlage Electronics LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating; the Dormakaba LX-I-M002 Saffire RFID mortise lockset with BLE mobile access at BHMA Grade 2; and the TownSteel FME-2000, a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. Each carries the reader in the lock trim. The Corbin Russwin ML20932 has no onboard reader; it is a double cylinder electrified mortise lockset that is released by a separate access control system and keyed on both sides through its 6-pin L4 cylinders.
19) For a classroom or behavioral health opening, what mortise lockset should I look at instead of the ML20932?
For classroom intruder-type security, 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 for 1-3/4 inch doors, and the BEST 45HCA intruder-function heavy duty mortise lockbody covers lock-from-inside classroom security. For ligature-resistant behavioral health openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever passage mortise lockset and the Marks USA 5PDN is a Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant. The Corbin Russwin ML20932 is an electrified double cylinder lockset for panel-controlled openings and is ADA compliant, with Behavioral Health BHSS/BLSS trim offered within the ML2000 Series.
20) Is there a simpler non-electrified option if I only need the door keyed on both sides like the ML20932, without access control?
Yes. The Corbin Russwin ML20932 is a double cylinder, both-grips-lock design, keyed on both sides through 6-pin L4 cylinders, with the added electrified Fail Safe or Fail Secure operation. For the same keyed-both-sides intent without electronics, the Marks USA 21AC and 22AC are entrance double cylinder mortise locks, and the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset for openings where a deadbolt alone satisfies the function. Drop the electrification only if the opening truly has no access control requirement, since the ML20932 is what lets a panel release the door.
21) Can I keep my existing keyway if I switch to the ML20932, or do I need to standardize on Corbin Russwin?
The ML20932 ships standard with a brass 6-pin L4 keyway cylinder, 0-bitted, and can be ordered as an interchangeable-core version less core or entirely less cylinder, and it will accept most other manufacturers' cylinders. That means it can join an existing Corbin Russwin key system or an existing IC core system you already stock. Among peers, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset also offers an interchangeable core option, and the Accentra NTM623-NR nexTouch Generation 3 mortise lock includes a cylinder override.
22) What are the alternatives to the ML20932 for a narrow stile aluminum storefront door?
The ML20932 is a heavy-gauge steel mortise lock case measuring 5-7/8 by 4 by 15/16 inch on a 1-3/4 inch door with a 2-3/4 inch backset, which is a standard commercial prep rather than a narrow storefront stile. For aluminum storefront work, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is made for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is listed as a wide stile electronic pushbutton mortise lock, and the Kaba Ilco BR Series is a glass door bottom rail lock. Confirm the existing stile prep before ordering any of them.
23) Do I have to order the ML20932 handed, or is there an advantage over peers that require handing at order time?
The ML20932 is field reversible and uses a patented quick reversible latchbolt, so handing can be changed without disassembling the lock case. Among peers, the BEST 45H public entrance mortise lock body and the Falcon MA101 Grade 1 heavy duty passage lock are also field reversible, while the Baldwin 6310190RRLS is supplied as a specific right hand reverse lever unit and the Schlage LEMD-GRW is a right hand wireless mortise lock. For a stocking position across mixed handings, the reversible bodies reduce how many part numbers you carry.
24) Can I change the lock function later without buying a new lock body?
Within the ML2000 Series, one ML2054 lock body covers 12 configurable functions, so a facility can stock fewer bodies and change function in the field. The ML20932 itself is the double cylinder, both-grips-lock electrified configuration, ordered fail safe or fail secure.
