Corbin Russwin ML194-RH-626-V01 – Frequently Asked Questions

1) Will the Corbin Russwin ML194 indicator kit work on my existing ML2000 mortise lock?
The ML194 is a retrofit status indicator kit for the ML2000 Series mortise lock, and it works with 27 ML2000 and ML20600 functions, including ML2002, ML2003, ML2011, ML2012, ML2013, ML2017, ML2020, ML2022, ML2024, ML2029, ML2030, ML2048, ML2049, ML2059, ML2060, ML2062, ML2065, ML2067, ML2068, ML2069, ML2072, ML2073, ML2075, ML2082, ML2092, and the ML20608 and ML20609 with NAC x SEC x PHR. Check the function number stamped on your lockbody against that list before ordering. It mounts to sectional trim, so an escutcheon-trim lock is a different part.
2) Do I have to order the Corbin Russwin ML194 indicator by handing?
Handing matters. The ML194 is ordered Left Hand or Right Hand, and every finish is offered in both, so the 626 Satin Chrome, 630 Satin Stainless and the other twelve finishes all come either way. The parent mortise lock itself is field reversible, but the indicator window is handed, so pick the hand that matches the door as installed.
3) Does adding a status indicator to my mortise lock affect the fire rating on the door?
The ML2000 Series mortise lock the ML194 retrofits is UL/cUL listed to UL10C positive pressure, rated for a 3-hour fire door up to 4 by 10 feet single or 8 by 10 feet pair, and it is ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1. It also meets ADA A117.1 and carries California State Fire Marshal listing. Those are the ratings behind the lock the indicator mounts to.
4) Will the ML2000 lock latch into my existing ANSI strike?
The latchbolt is a two-piece anti-friction unit measuring 5/8 x 1 inches with a 3/4 inch (19mm) throw, backed by a deadlocking auxiliary latchbolt at 9/16 inch (14mm) effective throw. The stainless deadbolt throws 1 inch. The supplied strike is ANSI straight lip, 4-7/8 x 1-1/4 with 1-1/8 inch lip to center. If your frame is prepped for a standard ANSI 4-7/8 strike, those throws land in it.
5) I need an occupancy indicator but my locks are Schlage L Series, not Corbin Russwin. What do I use?
The ML194 is built for the Corbin Russwin ML2000 mortise lock and will not mount to a Schlage L Series. For those, ZenSupply carries the Schlage 47804351 retrofit indicator kit for sectional locks with cylinder, reading LOCKED/UNLOCKED, and the 47804352 in the same configuration reading OCCUPIED/VACANT. Note both Schlage kits are the cylinder version, where the Corbin ML194-V01 is the thumbturn version.
6) Is the ML194 a whole lock or just the indicator part?
Just the indicator. The ML194 is a replacement part, a retrofit kit that adds the visible locked/unlocked window to sectional trim on an ML2000 mortise lock you already have or are ordering. It is not a lockset, so it does not include the lockbody, latch, strike, or cylinder.
7) What is the Schlage equivalent of the Corbin Russwin ML194 retrofit status indicator?
The closest Schlage part is the 47804351, an L Series retrofit indicator kit for a sectional lock with cylinder that reads LOCKED/UNLOCKED. Both are occupancy indicators that retrofit onto sectional trim. The difference is the lock family and the inside operator: the ML194-V01 goes on Corbin Russwin ML2000 Series mortise locks and is the thumbturn version, while the 47804351 is built for the Schlage L Series and is the cylinder version. Match the indicator to the mortise lock already in the door -- an L Series kit will not mount to an ML2000 lock, and vice versa.
8) I need an indicator that says OCCUPIED and VACANT instead of LOCKED and UNLOCKED -- what are my options?
The Corbin Russwin ML194-V01 displays Unlocked / Locked in green and red through its curved viewing window, with a LOCK engraving and directional arrow on the interior. If the wording on the restroom or exam room door needs to read OCCUPIED / VACANT instead, the Schlage 47804352 is an L Series retrofit indicator kit for a sectional lock with cylinder carrying that message. Note that it is an L Series part, so it suits a Schlage L Series mortise lock, not an ML2000 opening.
9) For a hotel guest room, is a DO NOT DISTURB indicator a substitute for a locked/unlocked indicator?
They answer different questions and are not direct swaps. The Schlage 47804353 is a sectional indicator on rose trim with interior or exterior cylinder prep that reads DO NOT DISTURB -- a courtesy message the occupant sets. The Corbin Russwin ML194-V01 reports the actual mechanical state of the ML2000 Series mortise lock, showing Unlocked / Locked in green and red as the thumbturn is turned. On a hospitality opening where staff need to know whether the door is genuinely secured, the status indicator is the one that reports lock condition; where the ask is guest privacy signalling, the DO NOT DISTURB indicator covers it.
10) Can I put a Schlage sectional indicator on a Corbin Russwin mortise lock?
No. The Schlage 47804351 and 47804352 are L Series retrofit indicator kits, built around Schlage L Series sectional trim. The Corbin Russwin ML194-V01 is engineered for the ML2000 Series mortise lock and is compatible with 27 ML2000 and ML20600 Series functions including ML2002, ML2013, ML2030, ML2060 and ML2075. Indicator kits are keyed to their own lock family's trim and spindle geometry, so a building standardized on ML2000 mortise locks takes the ML194 kit and a building on L Series takes the Schlage kit.
11) What does the Corbin Russwin ML194 indicator actually display?
A curved viewing window showing Unlocked in green and Locked in red on the interior side. The window is patent-pending and 25 percent larger than competing indicators, which is what makes it readable at an angle down a corridor rather than only head-on.
12) What backset and door thickness does the Corbin Russwin ML2000 mortise lock this indicator fits use?
2-3/4 inch backset and 1-3/4 inch (44mm) door thickness as standard, with optional thicknesses available. The lockcase is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches and the armored front is 8 x 1-1/4 inches. If your existing mortise pocket was cut for a 2-3/4 backset commercial lock, the prep matches.
13) How much space is there between the lever and the thumbturn on a Corbin Russwin ML2000 sectional trim?
Center to center, knob or lever to thumbturn is 2-7/16 inches (62mm), and knob or lever to cylinder is 3-5/8 inches (92mm). Those are the spacings the ML194 indicator has to live within on sectional trim, and they are what you check against an existing door face prep before you retrofit.
14) Can I use the ML194 indicator on a lock that is keyed to my building's existing key system?
Yes. The ML2000 Series works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so adding the indicator does not force a rekey. The standard cylinder is brass, 6-pin L4 keyway, 0-bitted from the factory so your locksmith can bit it into the existing system.
15) What is the difference between a thumbturn indicator kit and a cylinder indicator kit?
It comes down to what operates the lock from that side of the door. The Corbin Russwin ML194-V01 is the thumbturn configuration -- the interior side turns by hand and the window reports Unlocked / Locked. The Schlage 47804351 and 47804352 are both retrofit indicator kits for a sectional lock with cylinder, so the indicator surrounds a keyed cylinder rather than a thumbturn. Order the one that matches the trim prep already cut into the door, because the two are not interchangeable in the same hole.
16) Is there an indicator option without English text for a facility with multilingual occupants?
Yes. The Schlage 47804354 is a sectional indicator on rose trim with interior or exterior cylinder prep that uses symbols only, with no written message. The Corbin Russwin ML194-V01 takes the text route -- Unlocked / Locked in green and red, plus a LOCK engraving with a directional arrow on the interior -- so it relies on color as well as wording to carry the meaning. On an airport, transit, or campus opening where reading the word is not assumed, the symbols-only sectional indicator removes the language dependency.
17) Which indicator should I specify for a healthcare exam room door?
For an ML2000 Series mortise lock, the Corbin Russwin ML194-V01 gives a thumbturn the clinician can throw from inside with a curved window reporting Unlocked / Locked in green and red, which suits patient room privacy management on a lock carrying ANSI/BHMA A156.13 Grade 1 and UL10C 3-hour positive pressure listing. If the wording matters more than lock state -- staff wanting to see OCCUPIED rather than LOCKED -- the Schlage 47804352 carries an OCCUPIED/VACANT message, though it is an L Series kit with cylinder rather than thumbturn.
18) My door is prepped for a cylinder on the outside as well -- does the Corbin Russwin ML194-V01 handle that?
The ML194-V01 is the thumbturn configuration, mounting to sectional trim on the ML2000 Series mortise lock with the LOCK engraving and arrow facing the interior. Where the opening needs the indicator itself to accept a cylinder prep on either face, the Schlage 47804353 and 47804354 are sectional indicators on rose trim with interior or exterior cylinder prep -- the 47804353 reading DO NOT DISTURB and the 47804354 using symbols only. Those are Schlage parts, so confirm the mortise lock in the door before ordering.
19) Is the Corbin Russwin ML194 indicator durable enough for a high-traffic building?
The ML2000 lock platform it retrofits is cycle tested to 14.5 million cycles under UL verification ID V875753, well past the ANSI/BHMA A156.13 Grade 1 threshold it is graded to. It is specified as commercial hardware, which is the relevant point for a patient room, dorm, or multi-tenant corridor where the thumbturn gets worked several times an hour.
