Falcon T411LD A 626 – Frequently Asked Questions

1) What does the F87 asylum function on the Falcon T411 actually do at the door?
F87 is the double cylinder asylum/institution function: there is a keyed cylinder on both sides and neither lever retracts the latch by itself. A key is required from either direction to operate the lock. That is why it lands in detention, psychiatric, mechanical and utility rooms where you want positive control of movement in both directions. If you need free egress from the inside, this is the wrong function and you want a storeroom or classroom lock instead.
2) Can the Falcon T411 be keyed into my existing Schlage C keyway master key system?
Yes. Keyway is a required selection and C Schlage is one of the choices, alongside Falcon G, E, H, K, L, N and P. Keying options are keyed different, keyed alike, or to a specific key code you supply. The lock also takes small format interchangeable cores and Schlage full size interchangeable cores, so if your facility is on an SFIC system you order it less cylinder and drop your own core in.
3) Is the Falcon T411 fire rated for a 3 hour opening?
UL 10C rated, 3 hour A label. The outer trim is built to bottom out so the door does not collapse under fire conditions. It is also ANSI/BHMA Grade 1, F87 function, so it satisfies both the fire and the heavy duty side of an institutional spec.
4) My doors are 1-3/8 inch thick. What asylum or institutional lock should I use instead of the Falcon T411?
The T411 starts at 1-3/4 inch, so 1-3/8 inch doors are out of range. The Dexter C1000 asylum lock is rated 1-3/8 to 2 inch and carries the same Grade 1 F87 asylum function, which makes it the direct swap for thinner doors. Verify the cross-bore backset matches before ordering.
5) Is there a knob version of an asylum lock instead of a lever?
The Arrow MK33-BD-CS is an asylum/institution/utility cylindrical lock supplied with a ball knob rather than a lever, in a heavy duty Grade 2 build with a conventional cylinder in the Schlage C keyway. The Falcon T411 is a lever product in Grade 1. Where accessibility code drives the opening, the lever is the form that satisfies it; where a knob is wanted specifically to discourage casual operation in a utility or service space, the Arrow is the knob-trim route to the same double-keyed function.
6) Which lever lock has an inside thumbturn instead of a second key cylinder?
The Dexter C1000 classroom security lever is the alternative when the inside face should be operable without a key on hand. It is Grade 1 in the classroom security function with a clutching, keyed design and fits doors 1-3/8 inch to 1-3/4 inch thick. The Falcon T411 is double cylinder, meaning a key is required from both faces. For patient rooms and secure storage that must not be exited without a key, the T411 is the correct function; for a room an occupant must be able to leave freely, the classroom security lever is the one to specify.
7) Can a Grade 2 storeroom lever be used on a utility door instead of a Grade 1 asylum lock?
It is a different function, not a lighter version of the same one. The Cal-Royal AG05 is a Grade 2 storeroom 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 lock with the Withnell lever for doors 1-3/8 inch to 2 inch. Storeroom keeps the outside lever locked at all times while the inside lever always retracts the latch. The Falcon T411 is asylum function, Grade 1, keyed from both faces, so the inside lever is also locked. If free egress is acceptable, a storeroom lever fits; if it is not, only the double cylinder function will do.
8) Do I have to order the Falcon T411 handed for a left hand door?
No handing to specify. The T411 is non-handed and does not need field disassembly to re-hand, so one part number covers left and right hand openings. For a property manager or MRO stockroom that is one less variable to carry on the shelf.
9) Should I order the Falcon T411 less cylinder or with a cylinder?
Three cylinder choices at order: a 6 pin conventional cylinder supplied with the lock, less 6 pin cylinder, or less small format interchangeable core. Order it with the conventional cylinder if you have no house key system and want it usable out of the box. Order less cylinder or less SFIC if your locksmith is pinning to an existing facility system, which is the usual route in schools, hospitals and multi-family. Remember this is a double cylinder lock, so you are keying both sides.
10) Why do the levers on Falcon T Series locks not sag like other lever locks?
Lever sag is the usual failure on high traffic cylindrical locks, and the T411 uses compression springs in spring cages rather than the lighter spring return you find on lower grade locks. Falcon states they exceed ANSI/BHMA cycle test requirements and virtually eliminate sag. There is also Pressure Release lever rotation as standard: force the lever past its stop and it rotates rather than transmitting the load into the internal components. In a dorm, a detention corridor or a school, that is the difference between a service call and a lock that keeps working.
11) How is the Falcon T411 secured to the door, and can the levers be pulled off?
Trim is through-bolted with two 10-32 screws coated with thread sealant, so it clamps through the door rather than relying on wood screws. The inside lever is held by an Allen-head set screw, which keeps it from being twisted off by hand in a vandal-prone setting. Rose diameter is 3-1/2 inches, which is what covers the prep on the door face.
12) What is the difference between the Falcon T411 and the Corbin Russwin CL3110?
They are both Grade 1 cylindrical lever locks, but they do opposite jobs. The Corbin Russwin CL3110 is a vandal resistant passage/closet lever, fire rated, for doors 1-3/4 inch to 2 inch thick, and it is not keyed at all - the lever simply retracts the latch from either side. The Falcon T411 is keyed with a cylinder in both levers and fits doors 1-3/4 inch to 2-1/8 inch. Specify the CL3110 for corridor and closet doors in the same institutional building where no locking is wanted, and the T411 where both faces must be key controlled.
13) What lever should be ordered for the doors in the same building that do not need to lock?
For matching non-locking openings alongside a keyed institutional lever, the Design Hardware X75 is a Grade 1 passage lockset with a flat lever for 1-3/4 inch doors, and the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim - a fixed lever with no latch at all, for inactive leaves and closet fronts. The Falcon T411 handles the keyed openings in the same Grade 1 heavy duty class. Ordering passage, dummy, and keyed functions in one grade keeps the corridor consistent and the maintenance stock predictable.
14) Is a keypad lever lock a substitute for a keyed institutional lever?
It is not a like-for-like swap. The Lockey 2835DC is a double combination mechanical keyless lever lock in passage function for doors 1-3/16 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Both open on a code rather than a key. The Falcon T411 is a mechanical, non-electronic lock that accepts conventional cylinders, small format interchangeable cores, and Schlage full size interchangeable cores, so it drops into an existing master key system. Where a facility already keys its doors on one system, a code lock breaks that; where issuing keys is the problem, the keypad is the point.
15) The opening needs an electrified lever that unlocks on a fire alarm - what should be used instead?
The Corbin Russwin CL33903 is the electrified route. It is a Grade 1 fail safe cylindrical lever operating on 12VAC/DC for doors 1-3/4 inch to 2 inch thick, meaning it unlocks when power is removed. The Falcon T411 is a mechanical lock with no electronic component, so it holds its locked state independent of the building's power or access control system. Access-controlled openings and doors tied into an alarm release need the CL33903; standalone institutional doors on a key system are the T411's ground.
16) Can a Grade 3 residential lever be used on a commercial institutional door?
The Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for doors 1-3/8 inch to 1-3/4 inch, and the Master Lock BC Series RL01 is a Grade 3 keyed entry lever. Grade 3 is the residential-duty tier in the ANSI/BHMA scale. The Falcon T411 is a Grade 1 commercial lock rated heavy duty. On a healthcare, school, or correctional corridor where the cycle count runs high and abuse is expected, the grade is what the specification is written around, so the Grade 1 lock is the one that matches the drawing.
17) Does an asylum lock work on a bathroom or patient toilet door?
No - the function is wrong for it. A privacy lock is what a bathroom takes: the Arrow MK02-TA is a privacy/bed/bath cylindrical lock with a Tudor knob, fire rated, for doors 1-3/4 inch to 2 inch, and the Hager 2540 is a Grade 2 privacy lock with the Withnell lever for doors 1-3/8 inch to 2 inch. Those lock from inside and release with an emergency tool from outside. The Falcon T411 requires a key from both faces, which would leave an occupant unable to exit without one.
18) Which lever locks accept a Schlage keyway so they can go on the same key system?
The Falcon T411 can be ordered in the C Schlage keyway alongside G, E, H, K, L, N and P, and it accepts conventional cylinders, small format interchangeable cores, and Schlage full size interchangeable cores. Among the comparable levers, the Cal-Royal AG00 entrance lever and AG03 classroom lever are supplied with 6-pin Schlage C keyway cylinders keyed different, and the Arrow MK33-BD-CS asylum knob lock carries a conventional cylinder in the Schlage C keyway. For a facility standardizing one key system across mixed functions, those are the units that key together without an adapter.
19) Which heavy duty lever lock covers the widest range of door thicknesses?
The Falcon T411 adjusts from 1-3/4 inch to 2-1/8 inch, which is the range that reaches the thicker institutional leaves. Among heavy duty comparables, the Lockey 1150 keypad lever set covers 1-1/8 inch to 2 inch and the Lockey 2835 covers 1-3/16 inch to 2 inch, both reaching thinner doors but stopping at 2 inch. If the door measures over 2 inch - common on rated institutional and detention openings - the T411 is the one that still fits; on a thin gate or panel door below 1-3/4 inch, the Lockey range covers what the T411 does not.
20) Can I match the Falcon T411 lever style and finish to the rest of the building?
Seven lever styles are offered: Avalon, Boardwalk, Broadway, Dane, Latitude, Longitude and Quantum. 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 and 643E aged bronze. 626 satin chrome is the usual institutional standard, so if you are standardizing a facility that is the safe match to existing openings.
21) Does the Falcon T411 need power or wiring run to the door?
No wiring. The T411 is fully mechanical, key operated on both sides, with nothing to fail when the power drops. If your spec calls for an electrified cylindrical lever that releases on a signal, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC, rated for 1-3/4 to 2 inch doors.
22) Is there a Yale or Accentra cylinder adapter that lets a Schlage cylinder be used?
The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, in Grade 1, for apartment exit and public toilet function hardware. It exists because that hardware does not natively take a Schlage cylinder. The Falcon T411 needs no adapter of that kind - it accepts most manufacturers' cylinders directly, including conventional key systems, small format interchangeable cores, and Schlage full size interchangeable cores, and it is orderable in the C Schlage keyway from the start.
