Falcon T521PD D 626 – Frequently Asked Questions

1) Is the Falcon T521 lever lock approved for a fire rated office door?
UL 3-hour A label certified, with the rating tied to roses of at least 3-1/2 inches in diameter. The T521's rose is 3-1/2 inches, so the lock as supplied meets that condition. Note that office function keeps the inside lever free at all times, which is what egress on a rated opening requires.
2) What does the office function on the Falcon T521 actually do when someone locks it?
Office function (ANSI/BHMA F81) means the outside lever is locked or unlocked by key from the outside, and the inside lever always retracts the latch for free egress. It's the function you want on a tenant suite or an office door that gets locked at the end of the day and left unlocked during business hours, rather than a storeroom lock that stays locked at all times.
3) Can I key a Falcon T521 into my existing Schlage C master key system?
Yes. C Schlage keyway is one of the orderable options on the T521, alongside Falcon's own G keyway and E, H, K, L, N and P. The lock also accepts small format interchangeable cores and Schlage full size interchangeable cores, so a locksmith running an existing SFIC system can order it less cylinder and drop their own core in.
4) What's a Grade 1 alternative to the Falcon T521 if I need it on a 1-3/8 inch door?
The T521 starts at 1-3/4 inches, so it is the wrong lock for a 1-3/8 inch door. Of the Grade 1 cylindrical levers ZenSupply carries, the Dexter C1000 Series entry/office lock covers 1-3/8 to 1-3/4 inch doors in the same entrance/office function. The Dexter C1000 classroom and classroom security versions cover the same thickness range if the door needs one of those functions instead.
5) What is the closest Grade 1 substitute for a Falcon T521 office lever on a 1-3/4 inch commercial door?
The Dexter C1000 Entry/Office cylindrical lever lock is the nearest match in function and grade: it is a Grade 1 keyed cylindrical lever in the Entrance/Office function, with a door thickness range of 1-3/8 inch to 1-3/4 inch. The Falcon T521 is also a Grade 1 keyed cylindrical lever in the Office function, so the two cover the same opening type. The difference to check before ordering is thickness range and keyway: the T521 is supplied in the G keyway as standard and its door range runs from 1-3/4 inch up to 2-1/8 inch, so on doors thicker than 1-3/4 inch the Falcon is the one that covers the range.
6) The opening needs a classroom lock, not an office function. What lever should be used instead of a T521?
Office function means the lever can be locked and unlocked from the inside; a classroom opening needs the outside lever locked and unlocked by key only. The Dexter C1000 Classroom cylindrical lever lock is a Grade 1 keyed classroom-function lever with a clutching mechanism, covering doors 1-3/8 inch to 1-3/4 inch thick. Where the room requires the occupant to lock the door from inside with a key, the Dexter C1000 Classroom Security lever is the Grade 1 Classroom Security version of the same series. The Falcon T521 stays the right choice only where Office function is what the door schedule calls for.
7) Does a Falcon T521 work with Schlage keying, or is an adapter needed like the ones sold for Yale hardware?
No adapter is needed. The Falcon T521 accepts most competitors' conventional key systems, small format interchangeable cores, and Schlage full size interchangeable cores, and the Schlage C keyway is one of the keyway choices offered on the lock. By contrast, the Accentra 107S is a Schlage cylinder adapter kit made specifically for Yale hardware. If a facility is standardized on Schlage C, a T521 can be ordered on that keyway directly. Cal-Royal levers such as the AG00 entrance and the AG03 classroom are also supplied with a 6-pin Schlage C keyway keyed different.
8) How do I order a batch of Falcon T521 locks keyed alike for one building?
Keying is a required selection: keyed different, keyed alike, or to a specific key code you type in at order time. Keyed alike puts every lock in the batch on one key, which is what a property manager wants across a set of common doors. If your locksmith is pinning the cylinders, choose the less cylinder or less SFIC option and skip the keying selection entirely.
9) Will the 3-1/2 inch rose on the Falcon T521 cover the old holes from the lock I'm taking off?
The rose is 3-1/2 inches across, which is a large-diameter commercial rose and will hide most standard cylindrical prep and minor scarring around a 2-1/8 inch bore. It cannot be reduced, though, so on a narrow-stile door or a door with a decorative plate that limits the rose footprint, measure the free face first. The trim is held by two 10-32 through-bolt screws.
10) Do I need a Grade 1 lever like the Falcon T521, or will a Grade 2 do for my building?
Grade 1 is the heavy duty commercial tier, and the T521 uses compression springs that exceed ANSI/BHMA Grade 1 cycle testing and stop the lever sagging over time. That matters on high-traffic openings, schools, healthcare, multi-family common doors. For lower-traffic doors where the cycle count is modest, ZenSupply carries Grade 2 commercial levers such as the Hager 2525 entry lock and the Cal-Royal AG00 entrance lever, both rated for 1-3/8 to 1-3/4 inch doors, which is a range the T521 does not reach at the thin end.
11) How well does the Falcon T521 hold up to abuse in a school or public building?
Two things do the work here. Pressure Release lever rotation lets the lever turn under excessive force rather than transmitting it into the internal components, so a kid hanging off the lever doesn't wreck the chassis. And the inside lever is retained by an Allen-head set screw rather than a snap catch, so it can't be pulled off by hand. Combined with through-bolted trim on two 10-32 screws, it's built for institutional traffic.
12) Can the Falcon T521 be wired for access control or a card reader?
No. The T521 is a purely mechanical cylindrical lever, key operated only, with no electrified option. If the opening needs to be released electrically, ZenSupply carries the Corbin Russwin CL33903 Grade 1 electrified cylindrical lever in fail safe, 12V AC/DC, for 1-3/4 to 2 inch doors, which is the same door thickness territory the T521 works in.
13) Which levers can be handed and which are non-handed when stocking spares for a multi-building portfolio?
The Falcon T521 is non-handed and does not require field disassembly for re-handing, so one part number covers left and right hand openings. Some trim is ordered by hand instead: the Baldwin Estate 5103 half dummy is sold as a left hand item and a separate right hand item, so the hand has to be determined before ordering. For stocking spares across a portfolio, the non-handed lock reduces the number of line items held, while handed dummy trim has to be counted door by door.
14) What matches a Falcon T521 on doors in the same suite that only need to push and pull, with no lock?
For the non-locking openings, the Corbin Russwin CL3110 is a Grade 1 vandal-resistant cylindrical lever in Passage/Closet function, fire rated, for doors 1-3/4 inch to 2 inch thick, and the Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. For a door leaf that needs a lever with no latch at all, the BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed dummy. The Falcon T521 is a keyed single-cylinder lock, so it is the wrong choice on an opening with no locking requirement.
15) Is there a Grade 2 lever that can be used on lower-traffic doors in the same building as a Falcon T521?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch thick, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever covering 1-3/8 inch to 2 inch doors. For a keyed entrance opening, the Hager 2525 is a Grade 2 commercial cylindrical entry lock over the same 1-3/8 inch to 2 inch range. All of these are cylindrical lever locks like the Falcon T521, which is Grade 1 heavy duty and carries the ANSI/BHMA F81 office function. Match the ANSI function to the door schedule first, then the grade to the traffic on that opening.
16) Can a Kwikset or Baldwin lever be substituted for a Falcon T521 on a commercial corridor door?
They are different classes of hardware. The Kwikset 200BRNL Breton passage lever and the 300BRNL Breton privacy lever are Grade 3 sets for 1-3/8 inch to 1-3/4 inch doors, and the Baldwin Estate 5103 comes in passage, privacy, and left- and right-hand half dummy versions. None of those are a keyed Grade 1 lock. The Falcon T521 is a Grade 1 heavy duty commercial keyed cylindrical lever with Office function. On a corridor door with a Grade 1 line on the drawing, a Grade 3 residential-duty set or a dummy trim will not satisfy the spec.
17) The door needs to unlock on a fire alarm signal. What replaces a mechanical office lever there?
An access-controlled opening needs an electrified lock. The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock operating on 12VAC/DC for doors 1-3/4 inch to 2 inch thick, with the NZ lever and D rose version in the CL33903 series. The Falcon T521 is a mechanical lock with no electronic function, so it cannot be tied into an access control or alarm release circuit. Where only a keypad is needed rather than wired control, the Delaney LP250 is a Grade 2 electronic keypad leverlock.
18) What lever suits a patient room or utility door where the lock must not be defeated from inside?
Asylum function is the one to specify there, since it is keyed from both sides with no inside locking control. The Dexter C1000 Asylum lock is Grade 1 in the F87 asylum function and covers doors 1-3/8 inch to 2 inch thick. The Arrow MK33-BD-CS is a heavy duty asylum, institution and utility lock with a ball knob and a conventional Schlage C keyway cylinder. The Falcon T521 carries the F81 office function, which allows the occupant to lock the outside lever from inside the room.
19) Falcon T521 levers were installed on the offices. What should go on the restrooms and private offices that need privacy?
Privacy function is a separate lock, not an option on an office lever. The Arrow MK02-TA is a privacy, bed and bath lock with a Tudor knob for doors 1-3/4 inch to 2 inch thick and is fire rated. The Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever covering 1-3/8 inch to 2 inch doors, which keeps the lever shape consistent with the Hager 2510 passage and 2525 entry sets if those are used elsewhere in the same building. The Falcon T521 is a keyed office lock and is the wrong function for a restroom.
20) Which lever styles and finishes does the Falcon T521 come in?
Seven lever styles on the T521: Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude and Quantum. Eight finishes: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome and 643E aged bronze. 626 satin chrome is the usual commercial default if you're matching existing institutional hardware.
21) Is a mechanical pushbutton lever like a Lockey a substitute for a keyed office lock?
Only where the goal is to eliminate keys entirely. The Lockey 2835 is a mechanical pushbutton keyless lever lock in passage function, ADA compliant, for doors 1-3/16 inch to 2 inch thick, and the 2835DC is the double combination version over the same range. The Lockey 1150 is a heavy duty mechanical keypad lever set in passage function for 1-1/8 inch to 2 inch doors, with the 1150S offering an adjustable backset. Those are code-entry devices with no cylinder. The Falcon T521 is a keyed single-cylinder office lock, so it is the choice where the opening has to run on the building's key system and be master keyed with the rest of the doors.
22) What is the difference between a Grade 1 and a Grade 2 dummy trim when matching a heavy-duty lever elsewhere on the job?
The BEST 9K Series 1DT single dummy trim is Grade 1 and heavy duty, while the BEST 7KC Series single dummy trim is Grade 2 and medium duty; both are non-keyed cylindrical lever dummy trims. The Accentra 455LN Augusta is another Grade 1 heavy duty single dummy in the 5400 Series, and the Callan Bentley is a Grade 2 dummy lever. On a job carrying the Grade 1 heavy duty Falcon T521 on the active leaves, the Grade 1 dummy trims are the ones that match the duty level of the rest of the openings.
23) What lever trim goes on the exit device if the same corridor has cylindrical locks on the other doors?
An exit device takes its own lever trim rather than a cylindrical lockset. The Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device, tied to the CL3300 cylindrical lock series, for doors 1-3/4 inch to 2 inch thick, so the lever shape on the exit device can be kept consistent with the cylindrical locks in that line. The Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim in entry function from the ED-500 Series. The Falcon T521 is a bored cylindrical lock and mounts to the door itself, not to an exit device chassis.
24) For an apartment building, what pairs with a heavy-duty keyed office lever on the interior unit doors?
Inside the units, the doors that need no lock take a passage set. The Accentra 5301LN Augusta is a Grade 2 cylindrical lever in passage and closet function from the 5300 Series, and the 4601LN is a Grade 2 passage cylindrical lever with the same Augusta trim design from the 4600 Series, so the lever shape stays consistent between them. The Arrow GL01 is a Grade 2 non-keyed passage cylindrical lock with the Sierra lever for 1-3/4 inch to 2 inch doors. The Falcon T521 covers the keyed openings and is offered in seven lever styles including Avalon, Dane and Quantum, so the trim can be selected to suit the building.
