Corbin Russwin ML20914-LL-SAF Fail Safe Electrified Mortise Lock Body, Both Grips Locked when Energized with Outside Cylinder Override

Grade 1 Electrified Mortise Lock Body for High-Traffic Commercial Applications

The Corbin Russwin ML20914-LL-SAF is a Fail Safe electrified mortise lock body from the ML2000 Series, engineered for demanding commercial, institutional, industrial, and government environments. When energized, both grips are locked, with outside cylinder override capability retained for authorized entry. Designed for 1-3/4" (44mm) standard door thickness and constructed of heavy-gauge steel, this Grade 1 lock body features a patented Quick Reversible latchbolt and a 1" stainless steel deadbolt.

Corbin Russwin ML20914-LL-626-SAF – Frequently Asked Questions

1) What happens to the Corbin Russwin ML20914 when the power drops?
It unlocks. The ML20914 is a fail safe electrified mortise lock: both grips are locked while the solenoid is energized, and on power loss both levers release for free entry and egress. Outside cylinder override is retained, so a key still operates the outside lever when the lock is energized. If you need the opening to stay secure during a power failure, a fail safe function is the wrong choice.
2) What power supply do I need for the ML20914 electrified mortise lock?
Size the supply for 500mA peak and 15mA holding per lock. Inrush is the number that matters when you are running several locks off one panel or access control board, so total the 500mA peak figure across the doors that can energize at once rather than the holding current.
3) Will the ML20914 mortise lock body fit a 1-3/4 inch commercial door?
Yes, 1-3/4 inch (44mm) is the standard door thickness for this lock body, with optional thicknesses available. The backset is 2-3/4 inches and the steel lockcase measures 5-7/8 x 4 x 15/16 inches, which is the standard ANSI mortise pocket for a commercial opening.
4) Do I have to order the ML20914 handed, or can it be reversed on the job?
Handing is field reversible. The ML2000 Series uses a patented quick reversible latchbolt, so the hand is changed without opening the lock case. One body covers left and right hand openings, which is useful when you are stocking spares for a building rather than ordering per door.
5) Will the ML20914 latch into the strike already in my frame?
It latches with a 3/4 inch (19mm) throw two-piece anti-friction latchbolt, backed by a 9/16 inch deadlocking auxiliary latch and a 1 inch throw stainless deadbolt. The standard strike is an ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your existing frame carries a standard ANSI 4-7/8 inch strike prep at a 2-3/4 inch backset, the lock lines up; a non-ANSI or T-strike prep will need the frame reworked or a new strike.
6) Is the ML20914 just the lock body, or does it come with levers and a cylinder?
Body only. The ML20914 is the mortise lockcase itself, so you order trim (lever x lever design, roses or escutcheons), the cylinder, and the strike separately to complete the opening. Trim options across the ML2000 Series include Museo, Vineyard, and Behavioral Health BHSS/BLSS designs, and thru-bolted trim is used for alignment and added security.
7) Can I use my existing Corbin Russwin keys, or a cylinder from another brand?
Both work. The ML2000 Series lock body can be keyed into new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so you can stay on whatever keyway the building already runs. The standard Corbin Russwin cylinder is brass, 6-pin L4 keyway, supplied 0-bitted.
8) Can the ML20914 go on a fire rated door?
Yes. The ML2000 Series is UL/cUL listed and UL10C positive pressure rated, good for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. It also carries ANSI/BHMA A156.13 Series 1000 Grade 1 for operational and security, ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification.
9) The Accentra 8800FL body looks like a drop-in for my electrified mortise opening. Is it?
No. The Accentra 8800FL Series is a Grade 1 mortise lock body with field reversible handing but it is not the electrified fail safe equivalent. If the opening is tied to an access control panel and must unlock on power loss, the Corbin Russwin ML20914 is the fail safe electrified body for that duty, rated for 1-3/4 inch doors with a 3/4 inch latchbolt and the ANSI straight lip strike at 4-7/8 x 1-1/4 x 1-1/8 inch.
10) Should I add request-to-exit monitoring to the ML20914?
That is an order-time choice: the ML20914 body is available with or without request to exit monitoring. Add it when your access control system needs to know the inside lever was turned, so it can shunt the door alarm on legitimate egress. On a door with no alarm or monitoring tie-in, the non-RX body is all you need.
11) Is the ML20914 durable enough for a high-traffic entrance or school corridor?
It is built for that duty. Grade 1 per ANSI/BHMA A156.13, heavy-gauge steel lockcase with brass or bronze substrate components, and UL cycle tested to 14.5 million cycles (Verification ID V875753). For openings taking abuse, the ML2000VR vandal resistant option adds stainless escutcheons with tapered edges and Torx pin tamper-resistant screws.
12) What is the difference between the Corbin Russwin ML20914 and a mechanical mortise lock body?
The ML20914 is electrified, so the lever control is switched by your access control system rather than only by key or thumbturn, and it needs a power transfer through the hinge edge plus a supply sized for 500mA peak and 15mA holding. If the door does not need remote or credential control, a plain mechanical Grade 1 mortise body such as the Accentra 8800FL Series lock body is the simpler route, and it is also field reversible for handing.
13) How much room do I need between the lever and the cylinder when laying out an ML2000 door prep?
Center to center from knob or lever to cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). The armored front measures 8 x 1-1/4 inches. Use those figures when checking an existing mortise prep before you commit to the lock.
14) For a school standardizing on Grade 1 mortise lock bodies, how does the Accentra 8800FL compare to the Corbin Russwin ML20914?
Both carry an ANSI/BHMA Grade 1 rating and both are sold as lock bodies with field reversible handing, so trim and cylinder are specified separately in each case. The difference is the electrical function: the ML20914 is a fail safe electrified body that locks both grips when energized and keeps an outside cylinder override, while the Accentra 8800FL Series body is a mechanical lock body. A facility that mixes access-controlled and key-only openings can hold Grade 1 across both by using the ML20914 at the controlled doors and the 8800FL elsewhere.
15) What finishes does the ML20914 come in so it matches the rest of my building's hardware?
Fifteen finishes are offered: 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. 626 and 630 are the usual commercial standards if you are matching existing institutional hardware.
