Falcon B511PD D 626 – Frequently Asked Questions

1) Will the Falcon B511 entry/office lever fit a 1-3/8 inch door, and what about a thicker 2 inch door?
Both work. The B511 cylindrical lever lock is adjustable across a 1-3/8 inch to 2 inch door thickness range, which covers standard 1-3/4 inch commercial doors as well as older 1-3/8 inch interior doors and thicker 2 inch openings. No separate part number or spacer kit is involved, the chassis adjusts within that range.
2) Does the Falcon B511 lever lock need to be ordered handed, left or right?
No handing to specify. The B511 is a non-handed lever lock, and re-handing in the field takes no disassembly of the lock. For a property manager buying a batch across mixed openings, that means one part number covers every door regardless of swing.
3) What does entrance/office function mean on the Falcon B511, and is it the right function for an office door?
Entrance/office is the function where the outside lever is locked or unlocked by a pushbutton or turn on the inside, and the key retracts the latch from outside. The inside lever always turns free for egress. It suits a private office or a tenant suite door that staff lock at the end of the day. If you need a door that stays locked outside at all times and is only opened by key, storeroom function is the one to specify instead, such as the Hager 2580 or the Cal-Royal AG05. For a classroom door locked from outside by key only, look at the Cal-Royal AG03 classroom lever.
4) Do I have to buy the cylinder separately with the Falcon B511, and what are the choices?
Three cylinder routes on the B511. A 6-pin conventional cylinder supplied with the lock; less 6-pin cylinder, if you are supplying your own conventional cylinder; or less small format interchangeable core, where the lock arrives cored-ready and you drop in your own SFIC. The SFIC route is the one to take if you already run an interchangeable core system, since re-keying is done by pulling the core with a control key rather than removing the lock from the door. If you pick either less-cylinder option, set the keyway selection to None.
5) Can I key the Falcon B511 to my existing Schlage C keys?
Yes, Schlage C is one of the keyway choices when you take the lock with a 6-pin conventional cylinder. The full keyway list is C Schlage, G, E, H, K, L, N and P, and there is a key code field on the order if the cylinder needs to be cut to a specific bitting. If you are running interchangeable cores instead, order the less-SFIC version and use your own cores.
6) Is the Falcon B511 lever lock rated for a fire door?
The B511 carries a UL Listed 3-hour A label fire rating and is ADA compliant, which is what a facility spec normally calls for on a rated corridor or stair door. It is certified to ANSI/BHMA A156.2 Series 4000 Grade 2.
7) Can the Falcon B511 take interchangeable cores from another manufacturer?
Yes. The B511 accepts small format interchangeable cores, including cores from other manufacturers, which is what makes it usable on a retrofit where a building already runs an SFIC master key system. Order the less-SFIC version and install your existing cores rather than introducing a second key system.
8) What is the closest Grade 1 equivalent to the Falcon B511 entry/office lever lock?
The Dexter C1000 Series entry/office cylindrical lever lock is the Grade 1 counterpart in the same function. The Falcon B511 is a Grade 2 cylindrical entrance/office lever lock; the Dexter C1000-ENTR carries the same Entrance/Office function at Grade 1 with a clutching, keyed lever and a 1-3/8 inch to 1-3/4 inch door thickness range. The B511 is adjustable from 1-3/8 inch to 2 inch, so on a 2 inch door the Falcon covers a range the Dexter does not.
9) Is there another Grade 2 commercial entry lever lock that matches the Falcon B511 door thickness range?
The Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle and a 1-3/8 inch to 2 inch door thickness range, the same range the Falcon B511 adjusts across. Both are Grade 2 cylindrical keyed lever locks for entrance duty. The B511 is non-handed and takes interchangeable cores for re-keying without pulling the lock.
10) What should I use instead of the Falcon B511 if the door needs to stay locked from the outside at all times with free egress?
That is storeroom function, not entrance/office. The Falcon B511 is an entrance/office lock, where the outside lever can be left unlocked. For a storeroom opening, the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt and a 1-3/8 inch to 1-3/4 inch door thickness range, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever covering 1-3/8 inch to 2 inch doors.
11) Can a Cal-Royal AG00 entrance lever replace a Falcon B511 on the same door prep?
Check the backset before ordering. The Cal-Royal AG00 is an entrance lever with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, for doors 1-3/8 inch to 1-3/4 inch thick. The Falcon B511 ships standard with a 2-3/4 inch backset, so an existing B511 prep at 2-3/4 inch will not line up with the AG00 as supplied. The Cal-Royal AG05 storeroom leverset shares that 1-3/8 inch to 1-3/4 inch door range if the function suits.
12) Is the Cal-Royal AUS00 entrance/office lever the same thing as a Falcon B511?
They share the entrance/office function but not the grade. The Cal-Royal AUS00 is a Grade 3 entrance/office lever lock with a solid brass forged body for doors 1-3/8 inch to 1-3/4 inch thick. The Falcon B511 is Grade 2 and adjusts from 1-3/8 inch to 2 inch. If a spec calls for ANSI/BHMA Grade 2 on an office opening, the AUS00 will not satisfy it.
13) If the drawing calls for a Grade 1 electrified lever rather than the mechanical Falcon B511, what fits?
The Falcon B511 is a mechanical lock with no electronic option. Where access control needs to release the lever, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock at 12VAC/DC for doors 1-3/4 inch to 2 inch thick, available with the NZ lever and D rose. That is a narrower door range than the 1-3/8 inch to 2 inch the B511 adjusts across, so confirm the leaf thickness first.
14) Is Grade 2 enough for a busy commercial corridor, or should I step up to Grade 1?
Grade 2 is a medium-duty commercial rating, and the B511 is built for commercial use with individual heavy-duty lever return springs and through-bolted trim to keep the lever from sagging or the screws from backing out. It handles office suites, tenant doors, and multi-tenant residential. On a high-traffic entry, a school corridor, or a door that takes abuse, a Grade 1 heavy-duty cylindrical lock is the better spec: the Dexter C1000 in entry/office function is the direct Grade 1 counterpart of this function, and the Corbin Russwin CL3100 Series is a Grade 1 vandal-resistant option.
15) What lever styles and finishes does the Falcon B511 come in?
Two lever designs, Dane (D) and Quantum (Q), each offered in five finishes: 605 bright brass, 606 satin brass, 613 oil-rubbed satin bronze, 625 bright chrome and 626 satin chrome. Every lever and finish pairing is orderable, so matching an existing building standard is a question of picking the BHMA finish number already on your other doors. 626 satin chrome is the usual commercial default.
16) Is the Falcon B511 an electronic or keypad lock?
No, the B511 is a purely mechanical keyed cylindrical lever lock, single cylinder, with no electronics. If the door needs a keypad or access control, that is a different product: the Delaney LP250 is a Grade 2 electronic keypad leverset, and the Lockey 2835 is a mechanical pushbutton keyless lever with passage function. For an electrified fail-safe lever on 12VAC/DC, the Corbin Russwin CL33903 covers that.
17) For a residential-style entry lever instead of a commercial Grade 2 like the Falcon B511, what is available?
The Falcon B511 is built for commercial duty at Grade 2. For lighter residential or decorative entry openings, the Callan Artino and Callan Bennett are Grade 3 entrance leversets, the Bennett coming as a lever and deadbolt combo, and the Master Lock RL Series is a Grade 3 return style keyed entry lockset. The Deltana Manchester 6201, Morant 6411 and Linstead 6431 entry levers all cover 1-3/8 inch to 2 inch doors, the same thickness span the B511 adjusts across.
18) The Falcon B511 is keyed. What is the non-keyed lever for the doors that only need a latch?
Corridor and closet doors that only need to latch take a passage lever, which has no cylinder at all, unlike the keyed single-cylinder Falcon B511. The Hager 2510 is a Grade 2 passage cylindrical lever lock with the Withnell design for 1-3/8 inch to 2 inch doors, and the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever. For a Grade 1 passage lever, the Corbin Russwin CL3110 is vandal resistant and fire rated for 1-3/4 inch to 2 inch doors.
19) What looks like a Falcon B511 substitute but is only a dummy lever?
Dummy trim is a pull with no latch and no cylinder, so it cannot stand in for the keyed, latching Falcon B511. The BEST 7KC Series 1DT is a Grade 2 medium duty single dummy trim cylindrical lever, and the BEST 9K Series 1DT is the Grade 1 heavy duty single dummy. The Accentra 455LN Augusta is also a Grade 1 single dummy cylindrical lever. Order these only for an inactive leaf.
20) We want to stop issuing keys. What keyless lever replaces a Falcon B511 on an office door?
The Falcon B511 is a mechanical, non-electronic keyed lever. For keyless operation, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Emtek Classic keypad leverset is a keypad option in the Classic series. The Lockey 2835 is a mechanical pushbutton keyless lever with ADA compliance and passage function for doors 1-3/16 inch to 2 inch thick, with a double combination version in the 2835DC.
21) Is there a knob version of the Falcon B511 entrance function for tenants who prefer knobs?
The Falcon B511 is a lever. For an entrance-function knob, the Arrow RL Series HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for doors 1-3/8 inch to 1-3/4 inch thick. Note that a knob is not ADA compliant trim, so it does not suit openings on an accessible route.
22) What lever handles a restroom or patient room where the Falcon B511 entry/office function is wrong?
An entry/office lock like the Falcon B511 is keyed from the outside. A restroom or bedroom needs privacy function: the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for 1-3/8 inch to 2 inch doors, and the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed, fire rated, for 1-3/4 inch to 2 inch doors. For a utility or institutional room with no inside release, the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum function lock with a conventional cylinder in Schlage C keyway.
23) Does the Falcon B511 Schlage C keyway mean it can key into a Yale or Accentra system?
The Falcon B511 offers a C Schlage keyway among its keyway choices, so it can be cut to an existing Schlage C system. Going the other direction, the Accentra 107S is a Schlage cylinder adapter kit that fits Schlage cylinders to Yale hardware, which is a fitting kit for that hardware rather than a lockset in its own right and does not substitute for the B511.
24) I need matching passage and privacy levers to go with a keyed entry lock. What pairs with the Falcon B511?
The B511 is the keyed entry/office member of the Falcon B Series, and the B Series carries the same Dane and Quantum lever designs across its other functions, so a matching passage or privacy lever comes from the same series rather than another brand. If you are filling out a mixed opening from other lines instead, Hager's Grade 2 2510 passage and 2540 lever both cover the same 1-3/8 to 2 inch thickness range, and the Accentra 5301LN Augusta is a Grade 2 passage lever.
