Falcon MA521P AG 626 – Frequently Asked Questions

1) Will the Falcon MA521 mortise lock work on a 3-hour fire rated door?
Yes. The MA521 is UL listed for 3-hour fire doors, A label, so it can go on the openings a commercial building's fire plan calls A label. That covers the stair and corridor doors most office, healthcare and school jobs run into. It is a keyed entry/office function, so the lever is always free on the egress side.
2) Do I have to order the Falcon MA521 handed, or can I re-hand it in the field?
No handing to specify. The MA521 is field reversible, so the same lock goes on a left or right hand opening and you re-hand it on the job instead of stocking two versions. For a property manager keeping spares on a shelf, that means one part number covers every door in the building.
3) Can I get the Falcon MA521 to work on my existing small format interchangeable core keyway?
Cylinder choice is an order option, four ways. B ships less SFIC so you drop in your own small format interchangeable core. L ships less 6-pin conventional cylinder if you are pinning your own. P is a conventional 6-pin cylinder, and CP6 is a conventional 6-pin in the Schlage C keyway. If your building is already keyed on an SFIC system, pick B and use your cores.
4) What does entry/office function mean on the Falcon MA521, and is it the right function for a tenant suite door?
Entry/office is the function where the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. That is the normal pick for a tenant suite or an office you want to leave unlocked during business hours and key locked after. If you need the outside lever locked at all times with key access only, that is storeroom function instead, not this lock.
5) Will the Falcon MA521 fit a standard ANSI mortise pocket and frame prep?
Frame prep follows ANSI Standard A115.1, with strike options and lip lengths available. If your frames were prepped to A115.1 for an existing mortise lock, the MA521 goes into that same prep, and you match the strike lip to the frame reveal so the lip clears the jamb.
6) I need a classroom or storeroom function instead of entry/office. What should I order?
Entry/office is the wrong function for those. The MA521 is entry/office only. For classroom, the Cal-Royal NM8070 and the Corbin Russwin ML2003 are both Grade 1 classroom mortise locksets. For storeroom, look at the Cal-Royal NM8080 with interchangeable core option or the Accentra 8805FL Grade 1 storeroom mortise lock. For privacy on a restroom, the Cal-Royal NM8440 is the Grade 1 privacy mortise lockset with deadbolt.
7) What is the closest equivalent to the Falcon MA521 mortise entry/office lock from another manufacturer?
The Cal-Royal NM8050 is the nearest match on function and grade: it is a heavy duty Grade 1 mortise lockset with the Entrance/Office function, the same function the MA521 carries. The NM8050 is specified for 1-3/4 inch doors, while the MA521 is field reversible and offered with conventional 6-pin, Schlage C keyway 6-pin, less-conventional-cylinder and less-SFIC cylinder options. If the opening already runs a Falcon keyway program, the MA521 stays in it; if the job is being written around a single door thickness, the NM8050 covers the same office function.
8) The office door needs to stay locked outside at all times with a key always retracting the latch - is the MA521 the right function?
No. The MA521 is an Entry/Office function lock, which allows the outside lever to be left unlocked for business hours. For an opening that must stay secured on the outside at all times, a storeroom function is the correct choice: the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with the Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors.
9) Which mortise lock should be used when the office door has to be locked and unlocked from an access control system?
Use an electrified body rather than the mechanical MA521. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors. The Command Access ML190 Series is a heavy-duty motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC in a storeroom function, and the BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V/24V operation. The MA521 has no electronics, so it is the choice only where the opening is controlled by key alone.
10) Which mortise locks carry the same Grade 1 rating and a 3 hour fire rating as the Falcon MA521?
The MA521 is ANSI/BHMA Grade 1 and UL listed for 3-hour fire doors, A label. Among comparable mortise products, the Schlage Electronics LEMD-GRW ENGAGE Series wireless mortise lock is Grade 1 with a 3 hour fire rating, while the Schlage Electronics LEBMB-ADD mobile-enabled mortise lock also carries a 3 hour fire rating but is Grade 2. Where the specification calls for Grade 1 on a fire-rated opening without electronics, the MA521 meets it mechanically.
11) Is the Falcon MA521 Grade 1 for a high traffic commercial door?
Grade 1, heavy duty, and certified to ANSI/BHMA 156.13 Series 1000. That is the top mortise lock grade and the level a spec writer normally calls out for main entries, corridors and any door taking constant use. Build is cold-formed steel with zinc plating and dichromate, with forged escutcheons and a 2-piece anti-friction stainless latch bolt.
12) What lever and trim options do I have to pick when ordering a Falcon MA521?
Four things get specified: lever style, trim style, finish and cylinder. Levers are Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude, Quantum and Sutro. Trim is Gala or Napa. Finishes are 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. Keying is a separate required choice: keyed different, keyed alike, key code, or none if you selected a less-cylinder option.
13) Can I key a batch of Falcon MA521 locks alike across a building?
Keying is chosen at order time: keyed different, keyed alike, or to a key code you supply. Keyed alike is the usual call for a group of doors one person carries a single key for. If you run a masterkey system, order the B less-SFIC or L less-conventional-cylinder option and install your own cylinders so the locks join your existing system rather than starting a second one.
14) What else could I buy instead of the Falcon MA521 for an office or entrance function mortise lock?
The closest cross-brand equivalent is the Cal-Royal NM8050, a heavy duty Grade 1 entrance/office mortise lockset with auxiliary deadlatch, listed for 1-3/4 inch doors. Baldwin's 6301 lever by lever is an entry/apartment mortise body on a 2-1/2 inch backset for 1-3/4 inch and over. If the door is non-keyed office trim, Hager's 3850E is an office function mortise lock with lever and escutcheon on a 2-3/4 inch backset.
15) Does the Falcon MA521 mortise lock need power or wiring?
No power, no wiring. The MA521 is a mechanical, key operated mortise lock. If the opening needs electric lock or unlock, access control or credential reading, that is a different lock: the Schlage L9092EU with request to exit runs 12/24VDC on a 1-3/4 inch door, the BEST 45HW is a wired electromechanical mortise lock at 12V/24V, and the TownSteel FME-2000 is a Grade 1 mortise lockset with RFID.
16) Is there a non-keyed mortise lock for an interior door that does not need a cylinder?
Yes. The MA521 is a keyed single cylinder lock, so for openings that need no key, use a non-keyed body instead. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Hager 3810S is a Grade 1 passage mortise lock with rose and 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, and the 3810E is the same passage lock with an escutcheon. For a non-keyed office function, the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, 2-3/4 inch backset.
17) Can the Falcon MA521 be used on a restroom or bedroom door that needs a privacy lock?
No. The MA521 is an Entry/Office function with a single cylinder and a key. A privacy door needs an inside locking function with no key: the Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with 2-3/4 inch backset for doors 1-3/4 inch to 2 inch.
18) What is the difference between the Falcon MA521 and an electronic mortise lock with a keypad?
The MA521 is a mechanical lock with no electronics, keyed with a conventional or small format interchangeable core cylinder. Keypad and credential alternatives include the BEST 45HZ EZ Series electronic keypad mortise lock with key override, the Alarm Lock DL3500CR Trilogy Grade 1 electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 inch to 1-7/8 inch, and the Schlage CO-100 standalone electronic mortise lock with a keypad reader, Grade 1 heavy duty privacy function for 1-3/4 inch doors. Those manage access by code rather than by key, so the MA521 remains the option where the building runs a key system and needs no power or programming at the door.
19) Is a mortise lock body like the BEST 45H the same thing as the Falcon MA521?
They are not interchangeable orders. The MA521 is a complete keyed lockset supplied with lever style, trim style and finish selected - levers include Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude, Quantum and Sutro, with Gala or Napa trim. The BEST 45H is a heavy duty mortise lock body with public entrance function and field reversible operation, and the 45HCA is a heavy duty mortise lockbody with intruder function - lock bodies that take trim ordered separately. Confirm which one the takeoff calls for before ordering.
20) Does an Emtek mortise entrance lockset work as a substitute for a commercial Grade 1 mortise entry lock?
It does not fill the same role. The Emtek 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, meaning the trim does not operate a latch, and the 3019 Brisbane brass mortise entrance lockset is likewise dummy. The MA521 is a keyed Grade 1 commercial lock with an Entry/Office function and heavy duty rating. Order a dummy set only for an inactive leaf, not for the opening that needs to latch and lock.
21) What mortise lock is used on a behavioral health or ligature-resistant opening?
Those openings call for anti-ligature trim rather than a standard lever. 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, the MRX-A-01 is the same passage function in satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. The MA521 uses lever trim in styles such as Avalon, Dane and Quantum with forged escutcheons.
22) Can the Falcon MA521 be installed on a narrow stile aluminum storefront door?
The MA521 is a commercial mortise lock with forged escutcheon trim sized for standard commercial doors. Aluminum storefront and glass door openings are handled by different bodies: the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, the Kaba Ilco BR Series is a glass door bottom rail lock, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock specified for wide stile. Confirm the door construction before ordering the MA521.
23) What replaces a mortise entry lock when the door is not prepped for a mortise pocket?
A cylindrical lock installs into bored holes rather than a routed mortise pocket. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors. The MA521 is a mortise lock and needs the door and frame prepared to ANSI Standard A115.1, so verify the existing prep before choosing between them.
24) What mortise lock should be used for a classroom that needs to be locked down from inside the room?
An intruder or classroom security function does that, which the Entry/Office MA521 does not. The BEST 45HCA Series is a heavy duty mortise lockbody with intruder function, and the TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID technology, Grade 1 heavy duty for 1-3/4 inch doors. The TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID for the same door thickness.
25) Can I match the Falcon MA521 to the satin chrome or oil-rubbed bronze hardware already in my building?
Nine BHMA finishes are offered on the MA521: 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. 626 satin chrome and 630 satin stainless are the two most commonly specified on commercial openings, so a building standardized on either will match without a special order.
26) Is a mortise deadbolt a substitute for a mortise entry lock?
No - a deadbolt secures the door but provides no latch and no lever operation. The Sargent 4874 is a double cylinder mortise deadbolt with 2-3/4 inch backset in the 4870 Series, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt sold in a single pack. The MA521 is a single cylinder Entry/Office lock with a 2-piece anti-friction stainless steel latch bolt and lever trim, so it both latches and locks the opening on its own.
