Falcon MA851L DG 622 – Frequently Asked Questions

1) Is the Falcon MA851 fail safe or fail secure, and what happens to the door when power drops?
Fail safe. Cut power to the MA851 and the outside lever unlocks, so the opening becomes free entry during a power loss or fire alarm release. That is the behavior you want on a stair re-entry or an opening the fire alarm has to release, and the wrong behavior on a storeroom you need locked when the building goes dark. If the door must stay secured through a power failure, order the fail secure version of the MA Series electrified lock instead, not this one. Mechanically it is a storeroom function: outside lever always locked, key retracts the latch, inside lever always free for egress.
2) What voltage does the Falcon MA851 electrified mortise lock run on?
12 VDC or 24 VDC, and you pick one when you order. Match it to the power supply already feeding the access control panel before you specify, because the coil is voltage-specific and not field-changeable. If you are standardizing a building on a single supply, the BEST 45HW wired electromechanical mortise lock covers 12V and 24V operation as well.
3) Can I get request-to-exit signaling with the Falcon MA851, or do I need a separate REX device?
Request-to-exit is built into the lock as an ordering option, so you do not need a separate REX sensor or a REX bar on the opening. Choose RX Included and the lock reports inside lever movement back to the access control panel, which is how you shunt the door contact and avoid a forced-door alarm every time someone leaves. Choose Not Included if the panel already gets its egress signal elsewhere. This is a decision made on the order form, not in the field.
4) Will the Falcon MA851 work on a fire rated door?
Yes, it is UL listed for a 3 hour fire door, A label, which covers the openings a stairwell, corridor, or exit enclosure typically requires. One thing to weigh on a fire rated opening: this is the fail safe version, so it unlocks on power loss. That is intended where the fire alarm must release the door, but the latch itself stays latched and the door stays a fire barrier either way.
5) Does the Falcon MA851 have to be ordered handed, or can I re-hand it on the job?
Field reversible. The 2-piece anti-friction stainless steel latch bolt re-hands without pulling the lock body apart, so one lock covers left hand and right hand openings. That matters if you are buying for a fleet of doors and do not want to track handing per unit, or if the door swing on the drawing turns out to be wrong when you get to site. Contrast that with something like the Baldwin 6310190RRLS, which is sold as a specific right hand reverse lock.
6) Can I use my existing SFIC cores with the Falcon MA851, or do I have to key it to Falcon?
Both routes are open. Order the B option to get the lock less small format interchangeable core, then drop in the SFIC you already use in the building, including cores from manufacturers other than Falcon. If you run conventional cylinders instead, P gives you a conventional 6-pin cylinder and CP6 gives you a conventional 6-pin in the Schlage C keyway, which is the one to pick if the property is already on a Schlage C master system. L ships the lock less the 6-pin conventional cylinder so your locksmith supplies it. Keying is specified separately as keyed different, keyed alike, or to a key code you provide.
7) Should I use an electrified mortise lock like the Falcon MA851 or a standalone keypad or card lock?
Wired versus standalone is the real fork. The MA851 is a wired electrified mortise lock: it has no reader, no keypad, and no onboard user database, so it needs a power supply and a credential reader wired back to an access control panel. That is what you want when the opening has to sit on the building's access system with live control, real time lockdown, and RX reporting. If there is no panel and no cabling to the door, a standalone unit makes more sense, such as the Alarm Lock DL3500CR Trilogy Grade 1 electronic mortise lock with 300 user codes, or the Schlage CO-100 standalone electronic mortise lock with keypad reader. If you want credentials without pulling wire, the Schlage LEMD ENGAGE wireless mortise lock with a 125kHz proximity reader is the wireless path.
8) What door and frame prep does the Falcon MA851 mortise lock need?
Standard mortise prep to ANSI Standard A115.1 for the frame, cut with the manufacturer's templates for the lock body pocket. If the opening already carries an A115.1 mortise lock, the pocket and strike prep are the prep you need. What is different from a mechanical swap is the power transfer: an electrified lock needs a wire path from the frame into the door edge, so budget an electric hinge or door loop and a raceway through the door if the existing opening was never wired.
9) I need an electrified mortise lock but not fail safe. What else is there?
If the opening must stay locked when power drops, the MA851 is the wrong choice, since it releases the outside lever on power loss. Two alternatives worth pricing: the Command Access ML190 Series motorized mortise lock is field selectable between EL and EU operation on 24VDC with a storeroom function, so one unit covers either behavior and you set it at install. The Schlage L9092EU with 03A lever is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, running 12/24VDC on 1-3/4 inch doors.
10) If the opening does not need electrification, what mortise lock does the same job as a Falcon MA851?
For a mechanical-only storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for doors 1-3/4 inch thick. Both hold the same Grade 1 rating and storeroom function as the MA851 without the wiring, power supply, and access control integration the electrified MA851 requires.
11) What should I use instead of a Falcon MA851 if the opening needs a keypad or credential reader at the door rather than a wired access control panel?
The MA851 is a wired electrified lock that takes its unlock signal from a connected access control system. For a standalone opening, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Schlage CO-100 (SKU SCH-CO-100-MS-40-KP) is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader for 1-3/4 inch doors. For credentials rather than codes, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID.
12) The door schedule calls for a classroom mortise lock, not storeroom. What takes the place of a Falcon MA851 there?
The MA851 is a storeroom function lock, which keeps the outside lever locked at all times with key or electric release. For classroom function, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, also 1-3/4 inch. If the classroom opening is also electronic, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with classroom function and 300 user codes for doors 1-5/8 to 1-7/8 inch.
13) Which mortise locks match the Falcon MA851 on a 3-hour fire rated opening?
The MA851 is UL listed for 3-hour A label fire doors. Among comparable mortise locks, the Schlage LEMD-GRW carries a 3 hour fire rating at Grade 1, and the Schlage LEBMB-ADD carries a 3 hour fire rating at Grade 2 for 1-3/4 inch doors. If the specification requires both the 3-hour rating and Grade 1, the MA851 and the LEMD-GRW are the two that hold both, with the difference being that the MA851 is wired to a panel while the LEMD is a wireless ENGAGE Series lock with an onboard proximity reader.
14) Which mortise lock should I standardize on across a facility if some openings need SFIC keying and others do not?
The Falcon MA851 is ordered with a conventional 6-pin cylinder, a conventional 6-pin in the Schlage C keyway, less 6-pin conventional cylinder, or less SFIC, so both conventional and small format interchangeable core openings come off one model number. Among comparables, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset offered with an interchangeable core option for 1-3/4 inch doors, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series. The MA851 additionally holds the fail safe electrification for the openings on the access control system, which lets one series cover both the wired and mechanical doors.
15) Is the Falcon MA851 heavy duty enough for a high traffic commercial entrance?
It is built for exactly that. ANSI/BHMA 156.13 Series 1000, Grade 1 operational and security, heavy duty, with forged escutcheons and cold-formed steel components that carry zinc plating and a dichromate coating for corrosion resistance. Grade 1 is the top commercial tier under that standard, which is the level a school corridor, hospital wing, or municipal building spec normally calls out.
16) What lever and trim styles can I get on the Falcon MA851, and can I match the other doors in my building?
Eight lever designs are offered: Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude, Quantum, and Sutro, on either Gala or Napa trim. Finishes run 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 630 satin stainless, and 643E aged bronze. For a property manager matching a fleet, 626 satin chrome and 630 satin stainless are the two that most commercial openings are already standardized on, so an electrified door can be made to look identical to the mechanical ones beside it.
17) What is a non-electrified Grade 1 storeroom mortise lock I can use on the doors that do not need access control?
On openings with no power and no panel, skip the electrified body. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. The Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, which keeps it on the same SFIC key system as the electrified doors. Mixing wired locks on the controlled openings with mechanical storeroom locks elsewhere, all on one core system, is the normal way a facility is laid out.
18) Does the Falcon MA851 have a deadbolt?
No. It is a single cylinder storeroom lock, so security comes from the latch bolt with the outside lever locked at all times, not from a separate deadbolt throw. That is deliberate on an access controlled opening, since a deadbolt someone can throw manually defeats the panel's control of the door. If the opening genuinely needs a deadbolt, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt.
19) What is the difference between a Falcon MA851 and a BEST 45HCA mortise lock body?
The BEST 45HCAC is a heavy duty mortise lock body with public entrance function and field reversible operation in the 45H Series, and the BEST 45HCAINL is a heavy duty lock body with intruder function. Both are lock bodies, so lever, rose, and finish are ordered separately. The MA851 ships as a complete package: the lock body plus a lever style such as Avalon, Dane, or Quantum on Gala or Napa trim in finishes from 605 bright brass to 630 satin stainless. The MA851 is also field reversible and electrified for fail safe operation, which neither BEST body provides.
20) Is a Sargent 4874 mortise deadbolt a substitute for a Falcon MA851?
No. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset; it throws a bolt and carries no latch or lever. The MA851 is a keyed storeroom mortise lock with a lever or knob trim package and a 2-piece anti-friction stainless steel latch bolt, and it is electrified for access control. The same distinction applies to the Kaba Ilco 185 Series, which is a deadbolt function mortise lock, and the Alarm Lock DL4500, a Grade 1 electronic mortise deadbolt with a privacy keypad. A deadbolt cannot carry the latching and egress duty the MA851 handles.
21) For a dormitory or corridor opening with a deadbolt, what replaces a Falcon MA851?
The Sargent 7925 is a Grade 1 heavy duty mortise lock in the 7900 Series with dormitory exit function, rose trim, and a single cylinder deadbolt. It shares the MA851's Grade 1 heavy duty class but adds the deadbolt and dormitory exit behavior that a storeroom function lock does not provide. The MA851 is a single cylinder storeroom lock without a deadbolt, released by key or by the access control signal.
22) What mortise lock takes the place of a Falcon MA851 on an opening that must stay unlocked, like a corridor or closet?
A storeroom function lock like the MA851 keeps the outside lever locked; for a free-passage opening the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Hager 3810S is a 3800 Series passage mortise lock with rose and a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inch. The Hager 3810E is the same passage function with an escutcheon instead of a rose. None of these are keyed, so they suit openings where no credential is required.
23) Is a Schlage PC10 an alternative to a Falcon MA851?
No. The Schlage PC10 is a Grade 1 cylindrical lock, not a mortise lock, in the PC Series with passage function and a rose for 1-3/4 inch doors. It fits a bored hole, while the MA851 requires a mortise pocket prepared to ANSI Standard A115.1. The two are not interchangeable in the same door prep, and the PC10 is non-keyed passage where the MA851 is a keyed storeroom lock.
24) For a behavioral health or anti-ligature opening, what replaces a Falcon MA851?
The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset with passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function in ligature resistant arch trim, satin stainless. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so they do not carry the keyed storeroom security of the MA851; pick by whether the opening needs to lock at all.
25) Is a Codelocks CL2255 a lighter-duty option in place of a Falcon MA851?
The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series with a brushed steel finish, rated medium duty. The MA851 is heavy duty and Grade 1, built for high-traffic commercial openings and carrying a UL 3-hour A label fire rating. On a low-traffic interior door with no fire rating requirement, the duty difference may not matter; on a rated or high-abuse opening it does.
26) Are Emtek mortise entrance locksets an alternative to a Falcon MA851?
They are not. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are dummy function, meaning they mount as trim with no working latch or lock. The MA851 is a commercial Grade 1 keyed storeroom mortise lock with electrified fail safe operation. Dummy trim is for an inactive leaf; it cannot secure or latch an opening.
