Falcon T571PD D 626 – Frequently Asked Questions

1) What does the Falcon T571 corridor/dormitory function actually do at the door?
The T571 is an F90 corridor/dormitory lock: the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. Turn the key one way to lock the outside lever for the night, the other way to leave it unlocked for daytime traffic. It's a single-cylinder lock, so all the control is from the keyed outside side. That's the pattern dorm rooms, apartment corridors and multi-family unit doors are usually specified with rather than a storeroom lock, which stays locked outside at all times.
2) What door thickness does the Falcon T571 lockset handle?
1-3/4 inches through 2-1/8 inches, adjustable within that range. That covers standard commercial 1-3/4 inch doors and the thicker doors you run into on older institutional openings and some fire-rated assemblies. Below 1-3/4 inches it's the wrong lock, so on a 1-3/8 inch interior door look at a lockset rated down that far, such as the Dexter C1000 Series at 1-3/8 to 1-3/4 inches.
3) Can the Falcon T571 be keyed into my existing Schlage master key system?
Yes. Keyway is an order choice and includes C (Schlage) alongside Falcon's own G, E, H, K, L, N and P keyways, and the lock accepts most manufacturers' conventional key systems, small format interchangeable cores and Schlage full size interchangeable cores. Keying is specified as keyed different, keyed alike, or to a key code you supply. If your locksmith is supplying the cores, order it less cylinder and drop your own in.
4) Is the Falcon T571 approved for a fire-rated door?
Yes. The T571 carries a UL 3-hour A label rating for fire door applications and is certified to ANSI/BHMA A156.2 Series 4000 Grade 1. For an MRO or institutional spec that calls for a Grade 1 latch on a labeled opening, it meets it on both counts.
5) What is the closest Grade 1 cylindrical lever equivalent to the Falcon T571 if I need an electrified version on the same door?
The Falcon T571 is a mechanical Grade 1 cylindrical lever lock with no electrified option. For a Grade 1 cylindrical lever that runs on power, the Corbin Russwin CL33903 is a fail safe electrified cylindrical lever operating on 12VAC/DC, with a 1-3/4 inch to 2 inch door thickness range. Fail safe means the lever unlocks when power drops, so confirm that behavior suits the opening before swapping - the T571 corridor/dormitory function holds its state with no power at all.
6) I need a non-keyed lever on the same doors as my Falcon T571 corridor locks - what should I order?
The T571 is keyed with a single cylinder, so it is not the part for a closet or corridor door that never locks. For a Grade 1 non-keyed passage lever, the Corbin Russwin CL3110 is a passage/closet vandal resistant cylindrical lever, fire rated, for 1-3/4 inch to 2 inch doors. The Design Hardware X75 is another Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. Both are passage function only - no cylinder, no key.
7) Is a Grade 2 lever like the Hager 2580 an acceptable substitute for a Falcon T571 on a dormitory door?
They are built to different ANSI/BHMA grades and different functions. The Falcon T571 is Grade 1, heavy duty, corridor/dormitory function, which locks and unlocks by key from the outside while the inside lever always gives egress. The Hager 2580 with Withnell lever is Grade 2 storeroom function for 1-3/8 inch to 2 inch doors, and storeroom keeps the outside lever locked at all times. If the spec on the drawing calls Grade 1 or the door needs a corridor function, the 2580 does not meet it.
8) What Grade 1 cylindrical lever should I use for a classroom door instead of the Falcon T571?
The T571 is corridor/dormitory function, which is keyed on the outside for after-hours lockup rather than for a teacher locking the room from the corridor. For a classroom opening, the Dexter C1000 classroom lever is Grade 1 with a clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 classroom security version adds keyed control from both sides in the same Grade 1 line. The Cal-Royal AG03 is a classroom lever in the AG series with a 6-pin Schlage C keyway and a 2-3/4 inch backset, which matches the T571 standard backset.
9) My doors are 1-3/8 inch thick - can I still use the Falcon T571?
The Falcon T571 covers 1-3/4 inch to 2-1/8 inch door thickness, so a 1-3/8 inch leaf falls below its range. Levers that reach down to 1-3/8 inch include the Hager 2525 Grade 2 commercial entry lever at 1-3/8 inch to 2 inch, the Dexter C1000 asylum lever at Grade 1 for 1-3/8 inch to 2 inch, and the Cal-Royal AG05 Grade 2 storeroom lever at 1-3/8 inch to 1-3/4 inch. Match the function you need, since none of those is corridor/dormitory.
10) Can I use a residential grade lever like the Kwikset 200BRNL on an apartment corridor door instead of the Falcon T571?
They are built for different service. The Falcon T571 is a Grade 1 commercial heavy duty cylindrical lock with an F90 ANSI/BHMA function designation and a UL 3-hour A label rating for fire door use. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors, and passage function has no key at all. On a fire-rated corridor opening in a multi-family building the rating and the keyed function are the deciding facts, not the trim.
11) Do I have to specify handing when ordering a Falcon T571 lever lock?
No. The T571 is non-handed and field reversible without taking the lock apart, so one part number covers left and right hand openings. For a property manager or a distributor stocking spares, that means one lock on the shelf instead of two.
12) What is the difference between ordering the T571 with a cylinder and ordering it less cylinder?
Three cylinder choices: a 6-pin conventional cylinder supplied with the lock, less 6-pin cylinder, or less small format interchangeable core. The two less-cylinder versions ship with the housing prepped but empty, which is what you want when the facility keys everything itself on an SFIC system or a security integrator is pinning to an existing master. Order the 6-pin conventional if you want it keyed and ready to hang.
13) Will the T571 rose cover the holes left by the lock I'm taking off?
The rose is 3-1/2 inches in diameter. Measure the scarring or the old rose on your door before you order; anything wider than 3-1/2 inches will still show around the edge, and a knob-to-lever swap on an old prep is the usual place that bites people.
14) Is the Falcon T571 tough enough for a dorm or apartment corridor that takes constant abuse?
It's built for it. The lever is carried on compression springs rather than a torsion spring, which is what stops lever sag on high-cycle doors, and Falcon rates the spring design past ANSI/BHMA cycle testing. A pressure release lever rotation lets the lever turn under excessive force instead of breaking internals when someone hangs on it. Trim is through-bolted with two 10-32 screws with thread sealant, and the inside lever is held by an Allen-head set screw so it can't be pulled off by hand.
15) Should I use a cylindrical lock like the Falcon T571 or a mortise lock on my corridor doors?
A cylindrical lock like the T571 goes into a standard bored prep, two cross holes and an edge bore, which is why it's the faster and cheaper answer on a retrofit where the door is already bored for a knob or lever. A mortise lock needs a pocket routed into the door edge and is what you go to when you need multiple functions in one case or a deadbolt integrated with the latch. For a Grade 1 dorm or apartment corridor door on an existing bored prep, cylindrical is the normal call.
16) What is a Grade 1 alternative to the Falcon T571 if I need a different lock function on the same opening?
Corbin Russwin's CL3100 Series covers Grade 1 cylindrical in passage function, and it's fire rated with a 1-3/4 to 2 inch door thickness range. Dexter's C1000 Series covers Grade 1 in classroom, classroom security, entry/office and asylum functions. Both are cylindrical Grade 1 like the T571, so they drop into the same style of bored prep, but the T571 is the one carrying the F90 corridor/dormitory function where the key controls the outside lever and the inside always egresses.
17) Is a Grade 2 lever lock good enough instead of the Falcon T571, or do I need Grade 1?
Grade 1 is the top ANSI/BHMA cylindrical rating, tested to the highest cycle and strength thresholds, and it's what specs on institutional, healthcare, education and government work normally require. Grade 2 options like the Hager 2525 entry lever or the Cal-Royal AG05 storeroom lever are lighter duty and fine on lower-traffic doors. If a drawing calls out Grade 1, a Grade 2 lock will not satisfy it, and a dorm or apartment corridor door is exactly the traffic Grade 1 exists for.
18) Which lever matches my Falcon T571 doors on the leaf of a pair that does not latch?
An inactive leaf takes dummy trim, not a working lockset - the T571 is a keyed cylindrical lock with a 1/2 inch throw latch. For a Grade 1 heavy duty dummy in a commercial line, the BEST 9K Series 1DT is single dummy trim, non-keyed. The Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever in the 5400 Series. Lever style and finish will not match Falcon's Avalon, Dane or Quantum designs, so confirm the trim look before ordering for a visible pair.
19) I want keyless code entry on a door instead of the Falcon T571 - what lever locks do that?
The T571 is a mechanical keyed lockset with no electronic operation. For code entry, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the 2835DC adds a double combination. The Lockey 1150 is a heavy duty mechanical keypad lever set covering 1-1/8 inch to 2 inch doors, and the 1150S version has an adjustable backset. The Delaney LP250 is an electronic keypad leverlock at Grade 2. These are keypad devices rather than corridor/dormitory keyed locks, so the credential and the function both change.
20) Does the Accentra 107S adapter let me put a Schlage cylinder in a Falcon T571?
No. The Accentra 107S is a Schlage cylinder adapter kit made for Yale hardware, not for Falcon locks. The T571 already accepts a Schlage C keyway as an ordering choice alongside Falcon G, E, H, K, L, N and P keyways, and it takes conventional cylinders, small format interchangeable cores and Schlage full size interchangeable cores, so no adapter kit is involved. Specify the keyway when ordering rather than adapting after the fact.
21) What is a Grade 1 alternative to the Falcon T571 for a utility or behavioral health room where the lever must be keyed both sides?
Corridor/dormitory function on the T571 keeps the inside lever free for egress at all times. Where both sides need key control, the Dexter C1000 asylum lever is Grade 1 asylum/institution/utility function for 1-3/8 inch to 2 inch doors. The Arrow MK33-BD-CS is a heavy duty asylum/institution/utility lock with a ball knob and a conventional Schlage C keyway cylinder. Verify egress code for the room type before specifying a lock that keys from the inside.
22) For a private office door, is there something simpler than the Falcon T571?
An office door usually wants entry/office function, where the outside lever is locked or unlocked by a button or key and does not need corridor/dormitory dual-key control. The Dexter C1000 entry/office lever is Grade 1 with a clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors. The Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG00 entrance lever comes with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. Note the AG00 backset differs from the 2-3/4 inch the T571 lists as standard.
23) I need a privacy lever for the restroom on the same floor as my Falcon T571 corridor locks - what works?
Privacy function is a different lock entirely from the T571's keyed corridor/dormitory function. The Arrow MK02-TA is a privacy/bed/bath cylindrical lock with a Tudor knob, non-keyed, fire rated, for 1-3/4 inch to 2 inch doors. The Hager 2540 with Withnell lever is a Grade 2 privacy cylindrical lock for 1-3/8 inch to 2 inch doors and gives you a lever rather than a knob, which matters where ADA operable hardware is required.
24) Will the Corbin Russwin 585F715 lever work as replacement trim on a Falcon T571?
No. The Corbin Russwin 585F715 is a Grade 1 lock lever built for ED8000 pushpad exit device trim and the CL3300 cylindrical lock series, for 1-3/4 inch to 2 inch doors. It is exit device and CL3300 trim, not Falcon T Series trim. The T571 uses Falcon lever designs - Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude and Quantum - on a 3-1/2 inch rose, with inside levers held by Allen-head set screws.
25) What lever styles and finishes can I get on the Falcon T571?
Seven lever designs (Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude, Quantum) across 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. If you're standardizing a building, 626 satin chrome is the usual commercial default and matching the lever style across floors is what keeps a retrofit from looking patched.
26) Does the Falcon T571 need power or wiring at the door?
No wiring. The T571 is entirely mechanical, keyed on the outside with no electrification. If you need an access-controlled opening on the same style of bored prep, the Corbin Russwin CL33900 Series is an electrified Grade 1 cylindrical lever, fail safe, 12VAC/DC, for 1-3/4 to 2 inch doors.
