Falcon MA431P AG 626 – Frequently Asked Questions

1) What does the classroom security function on the Falcon MA431 actually do during a lockdown?
The MA431 is a double cylinder classroom security lock, which means it is keyed on both sides. A teacher can lock the corridor side from inside the room with a key, without stepping into the hallway. That is the whole point of the function versus a standard classroom lock, where the outside lever is only locked and unlocked by a key from the corridor side. Both cylinders are keyed, so control of the opening stays with whoever holds the key.
2) Can the Falcon MA431 mortise lock go on a fire rated door?
Yes. The MA431 is UL listed for 3-hour fire doors, A label. That covers the stair and corridor openings in a school or healthcare building where the door assembly carries an A label rating.
3) Do I have to order the Falcon MA431 handed, or can I re-hand it on site?
Order it as-is. The MA431 is field reversible, with a 2-piece anti-friction stainless steel latch bolt that re-hands in the field. For a contractor stocking a job with mixed swings, that means one part number covers left and right hand openings instead of two.
4) What do I have to specify when ordering a Falcon MA431 mortise lock?
Four choices plus keying. Cylinder prep (P, CP6, L or B), finish, lever style, and trim style. Levers run Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude, Quantum and Sutro; trim is Gala or Napa escutcheon. Keying is a required selection: keyed different, keyed alike, key code, or none if you picked a less-cylinder option. If you choose key code, supply the code with the order.
5) Is the Falcon MA431 Grade 1, and what standard is it tested to?
Grade 1, certified to ANSI/BHMA 156.13 Series 1000, the mortise lock standard. That is the heavy duty tier a school district or hospital spec will call for on high-traffic openings, and it is what separates this from Grade 2 hardware used on lighter interior doors.
6) Should I use a mechanical classroom security mortise lock or an electronic one for a school lockdown program?
The MA431 is fully mechanical, no electronics, so it works during a power outage and needs no batteries, credentials or software. It relies on someone having a key at the moment it matters. If you want credential control or audit history instead, the TownSteel FME-2000 Series is a Grade 1 classroom mortise lockset with RFID, the FME-4000 Series is the electronic intruder classroom version, and the Alarm Lock DL3500CR is a Grade 1 classroom electronic mortise lock with 300 user codes. Those bring their own battery and programming overhead; the mechanical lock does not.
7) What is a mechanical Grade 1 classroom mortise lock alternative to the Falcon MA431?
Two straight mechanical peers: the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset from the ML2000 Series, also 1-3/4 inch. Neither is described as double cylinder, so if what you need is the ability to key-lock the door from inside the classroom, the MA431 is the one that does that. The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset if you want a visual locked/unlocked indicator on the door.
8) Does the Falcon MA431 replace a cylindrical lock on my door?
No, not without new door prep. The MA431 is a mortise lock, meaning the lock body sits in a rectangular pocket routed into the edge of the door. A cylindrical lock uses a round cross bore through the face. Swapping from cylindrical to mortise means the door has to be prepped for the mortise pocket, or replaced. If you are working with an existing cylindrical prep and want to stay there, a cylindrical lock like the Schlage PC Series is the direction to go.
9) Which mortise locks accept a small format interchangeable core like the Falcon MA431?
The Falcon MA431 accepts conventional cylinders or a small format interchangeable core, and can be ordered less SFIC or less 6-pin conventional cylinder, or with a conventional 6-pin cylinder in a Schlage C keyway. Among comparable mortise locksets, the Cal-Royal NM8080 Grade 1 storeroom lockset for 1-3/4 inch doors offers an interchangeable core option. The BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, matching the MA431 on field reversibility.
10) What is the closest cross-brand equivalent to the Falcon MA431 classroom security mortise lock?
The Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch, prepared for 1-3/4 inch doors. The Corbin Russwin ML2003 is another Grade 1 mortise classroom lockset for 1-3/4 inch doors. Both match the Falcon MA431 on Grade 1 and on classroom function; the MA431 differs in being a double cylinder keyed function that is field reversible and carries a UL listed 3-hour A label fire rating.
11) What should I use for a classroom door that needs credential or keypad access rather than a key?
The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the TownSteel FME-4000 is an electronic intruder classroom mortise lockset with RFID, also Grade 1 heavy duty for 1-3/4 inch doors. For keypad entry, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with classroom function and 300 user codes, for doors 1-5/8 to 1-7/8 inch. The Falcon MA431 is a mechanical lock with no electronics.
12) What replaces a Falcon MA431 on a classroom door that needs remote lockdown from an access control system?
The Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile enabled deadbolt with LED, in Greenwich trim, right hand, with a 3 hour fire rating. The Command Access ML190 is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function, and the BEST 45HW is a heavy duty wired electromechanical mortise lock running 12V or 24V. All require power to the door. The Falcon MA431 is fully mechanical and locks at the door with a key.
13) Will the Falcon MA431 match the finishes on the rest of my building's doors?
Nine finishes are offered: 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 and 630 are the two that dominate commercial and institutional openings, so a property manager standardizing a portfolio will usually be matching one of those.
14) Is the Falcon MA431 built to hold up in a high abuse environment like a school corridor?
It is a heavy duty commercial lock. Forged escutcheons and cold-formed steel components, zinc plated with a dichromate treatment for corrosion resistance. Forged trim is the part that matters on abused openings, since cast or stamped escutcheons are what fail first when a lever gets hung on.
15) I need a mortise lock for a residential apartment door, is the Falcon MA431 the right pick?
Probably not. The MA431 is a commercial-rated classroom security lock, which is a specific function: keyed on both sides for lockdown control. For an apartment or dwelling unit entry you want an entrance or storeroom function instead. The Baldwin 6301 is an entry/apartment mortise lock body with a 2-1/2 inch backset, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch. If you do want the MA431's build on a non-classroom opening, look for a different function in the same Falcon MA Series rather than forcing this one.
16) What is the difference between the Falcon MA431 and an intruder function mortise lock?
The BEST 45HCA heavy duty mortise lockbody carries an intruder function, which is a distinct lockbody function from classroom. The Falcon MA431 is a classroom security function lock operated by double cylinder keying. If a lockdown specification calls out intruder function by name, the two are not interchangeable and the door schedule should be checked against the function code before ordering.
17) What mortise lock should I use for an office or entrance door instead of a classroom lock?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, non-keyed, for doors 1-3/4 to 2-1/2 inch. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom lockset with an interchangeable core option for 1-3/4 inch doors. The Falcon MA431 is built specifically for classroom security.
18) Is a mortise deadbolt an acceptable substitute for a double cylinder classroom lock?
No, it is a different part. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset and the Kaba Ilco 185 Series is a deadbolt mortise lock supplied with no handing; both are deadbolt-only bodies with no latch or lever operation. The Falcon MA431 is a keyed double cylinder classroom security mortise lock with a 2-piece anti-friction stainless steel latch bolt and lever trim.
19) What is the alternative to the Falcon MA431 for a dormitory or corridor door?
The Sargent 7925 is a Grade 1 heavy duty mortise lock with dormitory exit function, rose trim and a single cylinder deadbolt. Its corridor/dormitory function differs from the classroom security function of the Falcon MA431, which uses double cylinder keyed operation. For a privacy opening such as a restroom, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 to 2 inch.
20) Which mortise locks look like the Falcon MA431 but are non-keyed?
Several mortise bodies share the shape but carry no cylinder. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The Hager 3810E and 3810S are Grade 1 passage mortise locks on a 2-3/4 inch backset, the 3810E with escutcheon and the 3810S with rose, for doors 1-3/4 to 2-1/2 inch. The Schlage L0170 is a Grade 1 heavy duty half dummy trim with no lock function at all. The Falcon MA431 is keyed, with double cylinder classroom security operation.
21) Is the Schlage LE Series mobile enabled mortise lock a Grade 1 alternative to the Falcon MA431?
The Schlage LEBMB-ADD mobile-enabled mortise lock is Grade 2 with a 3 hour fire rating, for 1-3/4 inch doors, in push button and LED configuration covering privacy, office and apartment functions. If the specification calls for ANSI/BHMA Grade 1, it does not meet it. The Falcon MA431 is Grade 1 with a UL listed 3-hour A label fire rating.
22) Can I use a Marks USA 21AC or 22AC mortise lock in place of a Falcon MA431?
Not on a standard commercial door. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with round knobs, prepared for 1 inch doors. They share the double cylinder keying idea but suit ornamental iron gates and storefronts at that thickness. The Falcon MA431 is a heavy duty commercial classroom security lock with lever trim available in eight lever styles.
23) What is the anti-ligature alternative to the Falcon MA431 for behavioral health openings?
The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function in satin stainless steel with ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. All three are passage function; the Falcon MA431 is keyed for classroom security.
24) What is the difference between the Falcon MA431 and a cylindrical lock for the same opening?
The Schlage PC10 is a Grade 1 passage cylindrical lock with rose, non-keyed, for 1-3/4 inch doors. A cylindrical lock installs into bored holes, while the Falcon MA431 is a mortise lock requiring a routed pocket in the door edge. The two are not interchangeable without re-preparing the door, so an existing cylindrical prep needs a cylindrical replacement.
25) Is the Codelocks CL2255 a substitute for a Grade 1 classroom mortise lock?
The Codelocks CL2255 is a medium duty electronic tubular mortise latch in a brushed steel finish. Its duty level is medium rather than heavy duty, and it is a latch rather than a keyed classroom security lock. The Falcon MA431 is heavy duty Grade 1 with a UL listed 3-hour A label fire rating, which a fire-rated classroom opening will require.
26) Which mortise entrance locks are residential-style rather than commercial like the Falcon MA431?
The Baldwin 6301 entry/apartment mortise lock body comes in knob by knob and lever by lever versions on a 2-1/2 inch backset for doors 1-3/4 inch and over, and the Baldwin 6310 entry/storeroom body on the same 2-1/2 inch backset covers 1-3/8 inch and over. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are dummy function mortise entrance locksets. The Falcon MA431 is a commercial heavy duty Grade 1 lock.
