Corbin Russwin ML197-RH-626-V20 – Frequently Asked Questions

1) What does the Corbin Russwin ML197-V20 indicator actually do, and where does it mount?
The ML197-V20 is a single status indicator that mounts in Exterior Sectional Mortise Trim on an ML2000 Series mortise lockset. The outside face reads "Vacant / Occupied" in green and red. There is no indicator on the inside of the door, so the room occupant sees a plain rose while anyone in the corridor can read the status at a glance. It is a trim component, not a lock, so it goes onto an ML2000 lockbody rather than replacing one.
2) Which ML2000 Series lock functions will the ML197-V20 indicator work with?
It is listed for ML2003, ML2011, ML2040, ML2059, ML2073, and ML20609 x NAC x PHR. The V20 configuration is the "without input" (blank) version, meaning there is no cylinder or turn passing through the indicator itself, which is why it suits passage and office-type functions in that list. If your opening uses a function outside that group, match the indicator to the function before you order.
3) Do I have to order the Vacant/Occupied indicator handed, or can it be flipped in the field?
Both. The indicator is stocked left hand and right hand, and the V20 is field reversible, so an installer can correct the orientation on site if the wrong hand shows up or the door gets re-hung. On the lock side, the ML2000 lockbody uses a quick reversible latchbolt that re-hands without opening the case, so the whole assembly can follow a door swing change.
4) Will a Vacant/Occupied indicator like this fit a fire-rated door?
The ML2000 Series mortise platform it mounts to is UL/cUL listed to UL10C positive pressure and carries a 3-hour rating up to a 4' x 10' single door or an 8' x 10' pair. It also holds ANSI/BHMA A156.13 Series 1000 Grade 1 for operational and security, plus ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification. Use the lock and trim as an assembly to keep those listings intact.
5) What door prep does the ML2000 mortise lock behind this indicator need?
Standard prep is a 1-3/4 inch (44mm) door with a 2-3/4 inch (70mm) backset; other thicknesses are available as an option. The lockcase is heavy-gauge steel at 5-7/8 x 4 x 15/16 inches with an 8 x 1-1/4 inch armored front. Center to center from knob/lever to cylinder is 3-5/8 inches, and knob/lever to thumbturn is 2-7/16 inches, which is what determines whether the trim and indicator land on your existing cutout.
6) I need a cylinder in the same rose as the indicator. Is the V20 the right one?
No. The V20 is the without-input (blank) version, so there is no cylinder or turn through it. If your function calls for a key cylinder or thumbturn in the indicator position, you need a different ML197 configuration. Among other brands, the Schlage 47804353 and 47804354 sectional indicators are built with interior or exterior cylinder prep, the 353 reading DO NOT DISTURB and the 354 using symbols only.
7) Does this indicator work with escutcheon trim or only sectional?
Sectional only. The ML197-V20 is built for Exterior Sectional Mortise Trim. Corbin Russwin offers status indicator options for both sectional and escutcheon trim across the ML2000 line, so if your openings run escutcheon plates you need the escutcheon version instead of this one.
8) What is the Schlage equivalent of the Corbin Russwin ML197-V20 Vacant/Occupied indicator?
The closest Schlage counterpart is the 47804352 L Series retrofit indicator kit for sectional locks with cylinder, which carries the OCCUPIED/VACANT message. Both are occupancy indicators for sectional mortise trim and read the same wording. The difference is the platform: the ML197-V20 is built for Corbin Russwin ML2000 Series sectional mortise trim and lists functions such as ML2003, ML2011, ML2040, ML2059 and ML2073, while the Schlage kit is for the Schlage L Series. Indicators are not interchangeable across lock lines, so match the indicator to the lockset brand already in the door.
9) I need LOCKED/UNLOCKED wording instead of Vacant/Occupied on a sectional mortise trim - what do I order?
The ML197-V20 displays "Vacant / Occupied" in green and red on the exterior only, so it is not the part for a locked/unlocked message. On the Schlage L Series side, the 47804351 retrofit indicator kit for sectional locks with cylinder carries the LOCKED/UNLOCKED message. Choose based on which lock line is in the door and which wording the spec calls out.
10) My sectional trim has a cylinder in it - is the ML197-V20 the right indicator?
The V20 configuration is without input, meaning a blank exterior face with no cylinder prep, indicator outside and nothing inside. If the trim needs to accept a cylinder through the indicator, the Schlage 47804351 and 47804352 kits are described as being for sectional locks with cylinder, and the 47804353 and 47804354 sectional indicators list interior or exterior cylinder prep. Those are Schlage L Series parts; on a Corbin Russwin opening, confirm the ML197 configuration that matches the trim prep before ordering.
11) Will the existing strike still catch if I put an ML2000 mortise lock on this opening?
The latchbolt is a two-piece anti-friction design with a 3/4 inch (19mm) throw, backed by a deadlocking auxiliary latch at 9/16 inch (14mm) effective throw, and the deadbolt is one-piece stainless with a 1 inch (25mm) throw. The matching strike is an ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame is prepped for a standard ANSI 4-7/8 strike, the throws land where they should; a shallower lip or a nonstandard frame prep will need the strike changed out.
12) What finishes does the Corbin Russwin ML197-V20 indicator come in so I can match the rest of my hardware?
Fourteen finishes, each offered left hand and right hand: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, 722 black oxidized bronze oil-rubbed, and BSP black suede powder coat. For most commercial buildings the match is 626 or 630.
13) Is a green/red Vacant-Occupied indicator durable enough for a hotel or clinic corridor?
The ML2000 platform it rides on is tested to 14.5 million cycles under UL verification ID V875753 and holds ANSI/BHMA Grade 1 for both operation and security. The sectional trim is thru-bolted for alignment and security, and the indicator is fastened with Torx security screws to resist tampering. That is the build level facilities standardize on for hotels, exam rooms, faculty offices, and fitting rooms.
14) Can I keep my building's existing keys if I standardize on ML2000 locks with these indicators?
Yes. ML2000 locks work with new or existing Corbin Russwin key systems and will accept most other manufacturers' cylinders, so an existing masterkey system usually carries over. The stock cylinder is brass, 6-pin, L4 keyway, supplied 0-bitted so your locksmith can pin it to the building system. Note the V20 indicator itself takes no cylinder, so keying decisions sit with the lockbody and trim, not this part.
15) Is there an indicator option with no wording at all, just symbols?
Not in the ML197-V20 configuration - it is a word-based indicator reading "Vacant / Occupied" in green and red on the exterior. If a symbols-only face is what the job needs, the Schlage 47804354 sectional indicator uses symbols only on rose trim with interior or exterior cylinder prep. It is a Schlage L Series part, so it will not mount to Corbin Russwin ML2000 sectional trim.
16) Can I retrofit an indicator onto existing sectional locks, or does it have to be ordered with a new lock?
Both routes exist. The Schlage 47804351 and 47804352 are sold as retrofit indicator kits for sectional locks, so they address an already-installed L Series lock. The Corbin Russwin ML197-V20 is a replacement part for ML2000 Series sectional mortise trim and is field reversible, so it can be set to either hand on site, and it is offered in left hand and right hand versions across finishes from 605 bright brass to 630 satin stainless and BSP black suede powder coat.
