Falcon K561CP6D D 626 – Frequently Asked Questions

1) Will the Falcon K561 classroom lock fit a 1-3/4 inch door, and what about thicker doors?
Door thickness range on the K561 is 1-3/8 inches to 2-1/4 inches, so a standard 1-3/4 inch commercial door is well inside the range, and so are thicker doors up to 2-1/4 inches without any special kit. That upper end is wider than a lot of cylindrical locks give you, which matters on older institutional doors and on doors that have been faced or clad.
2) What does classroom function mean on the Falcon K561, and is it the right function for a classroom door?
Classroom function (ANSI F84) means the outside lever is locked and unlocked only by key from the outside. The inside lever always retracts the latch, so the room is never locked from egress, and there is no push button or turn on the inside for a teacher to set. If you want staff to be able to lock the door from inside the room during a lockdown, this is the wrong function and you want a classroom security or storeroom style instead. The K561 is the traditional key-outside-only classroom lock.
3) Can I put the Falcon K561 on a fire rated door?
Yes. The K561 is UL Listed for a 3 hour A label opening, so it can go on fire rated door assemblies up to that rating. It also carries ANSI/BHMA Grade 1 for heavy duty commercial use, which is what most school and healthcare specs call for on a corridor door.
4) What bore does the Falcon K561 need in the door?
A 2-1/8 inch cross bore with a 1 inch edge bore per ANSI A115.1 prep, which is the standard cylindrical prep on commercial doors. The latch housing is 1 inch in diameter to suit that edge bore. If the door is already prepped for a cylindrical lockset at the right backset, no new drilling is needed.
5) Which cylinder option should I pick on the Falcon K561 if my building is already keyed to Schlage C?
Order the P6 cylinder option, a conventional 6-pin cylinder in the Schlage C keyway, and it will key into an existing Schlage C system. If your site runs small format interchangeable core, choose H to get an SFIC housing with a refundable construction core, or B to receive the lock less SFIC so you can drop in your own cores. L comes less the 6-pin conventional cylinder. The default P is a 6-pin housing keyed 5-pin in the Falcon G keyway, keyed different.
6) How is the Falcon K561 different from a Grade 2 classroom lock like the Cal-Royal BA03?
Same classroom function, different duty class and different door range. The Cal-Royal BA03 is a Grade 2 ANSI F84 classroom lock covering 1-3/8 to 1-3/4 inch doors. The Falcon K561 is Grade 1 heavy duty, covers 1-3/8 to 2-1/4 inch doors, and is UL Listed for a 3 hour A label opening. For a light traffic interior office door the Grade 2 is the usual choice; for a high traffic school corridor or a fire rated opening, the Grade 1 is what the spec normally calls for.
7) I need a lock for an office or entry door, not a classroom. What should I order instead of the K561?
Classroom function locks the outside lever by key only, with no inside control, which is wrong for an office where staff want to secure the room from inside. For entry/office duty in the same heavy duty Grade 1 class, look at the TownSteel CDC-109 or CEC/CECI-109 (clutched) or the CE/CEI-109 (non-clutched). At Grade 2 for lighter doors, the Cal-Royal BA00 entrance lock has a turn/push button inside and covers 1-3/8 to 1-3/4 inch doors. For a door that must stay latched and locked outside at all times, the storeroom function Cal-Royal BA05 is the ANSI F86 option.
8) What is the closest classroom function alternative to the Falcon K561 from another brand?
The Cal-Royal BA03 in the Barrington BA series is also a classroom function cylindrical lock built to the ANSI F84 function, which is the same function designation the K561 carries. The differences that matter on the opening are grade and door range: the K561 is ANSI/BHMA Grade 1 and fits doors from 1-3/8 inch to 2-1/4 inch, while the BA03 is Grade 2 and fits 1-3/8 inch to 1-3/4 inch. If the door is thicker than 1-3/4 inch, or the spec calls for Grade 1, the K561 is the one that matches.
9) What looks like a substitute for the K561 but will not actually secure the door?
The TownSteel CRX-A-41 is a Grade 1 heavy duty cylindrical lockset like the K561, but it is a single dummy - trim only, with no latch and no key. It is a ligature resistant stainless steel arch trim unit for the inactive side of an opening, and it fits 1-3/4 inch doors. The Falcon K561 is a keyed classroom lock with a live latch and a cylinder, so the two are not interchangeable even though both are Grade 1 cylindrical.
10) We want to lock down classrooms remotely. Is the Falcon K561 the right choice?
No - the Falcon K561 is a mechanical lock with no electronic operation, secured by key at the door. For remote lockdown of a classroom, the BEST 9KW series is an electromechanical cylindrical lock with remote control operation, heavy duty like the K561. Choose the K561 where lockdown is done with a key at the opening, and the 9KW where the door needs to be secured from a central point.
11) Our doors are 2 inches thick. Which cylindrical locks will fit?
The Falcon K561 covers a door thickness range of 1-3/8 inch to 2-1/4 inch, so a 2 inch leaf is inside its range. The Cal-Royal Barrington locks - BA00, BA03, BA04 and BA05 - are each rated 1-3/8 inch to 1-3/4 inch, and the TownSteel CRX-A-41 is listed for 1-3/4 inch doors, so a 2 inch door falls outside all of them. On thick leaves the K561 is the fit.
12) Do I have to order the Falcon K561 left hand or right hand?
No handing to specify. The K561 levers are non-handed, so one part number covers both swings. For a facility standardizing across dozens of openings, that means a single stocked lock covers every door instead of splitting your shelf inventory into LH and RH.
13) Why does the lever on the Falcon K561 turn freely when the door is locked?
That is the clutch working as intended. The K561 uses a clutching lever, so when the outside is locked the lever rotates without retracting the latch instead of transmitting force into the chassis. On a school corridor where students pull on locked levers all day, that is the difference between a lock that survives the year and one that gets replaced. If you specifically want a non-clutched chassis, the TownSteel CE/CEI-109 is a Grade 1 non-clutched cylindrical lockset.
14) Is the Falcon K561 built to hold up in a school corridor or a hospital wing?
Chassis is brass or steel, zinc plated and dichromated for rust resistance, with stainless steel springs, and it is rated heavy duty at ANSI/BHMA Grade 1. It mounts with four through-bolted screws rather than surface screws, which is what keeps the lock tight on a door taking hundreds of cycles a day and makes it harder to pull apart from the outside.
15) Is a clutched lever important, and which alternatives have one?
A clutching lever lets the lever move when the lock is secured without retracting the latch, so forcing the lever does not drive load into the chassis - useful on school and institutional traffic. The Falcon K561 uses a clutching lever design. Among the alternatives, the TownSteel CDC-109 and CEC-109 are both described as clutched, while the TownSteel CE/CEI-109 is a non-clutched extra heavy duty lockset. If a clutch is on your spec, the CE-109 is the one to rule out.
16) Which of these cylindrical locks can I put on a fire rated classroom door?
The Falcon K561 is UL listed for a 3 hour A label, so it is the one to specify when the classroom door is part of a fire rated assembly. Among the alternatives, the Grade 1 TownSteel CE-109, CEC-109 and CDC-109 are entry/office function rather than classroom, and the CRX-A-41 is a dummy trim, so none of them substitutes for the K561 on a fire rated classroom opening.
17) What is the difference between the extra heavy duty TownSteel CE-109 and the Falcon K561 for a school corridor?
Both are Grade 1 cylindrical locksets rated heavy duty. The functions differ: the K561 is classroom function, keyed and non-handed, while the CE/CEI-109 is entry/office function and non-clutched. For a classroom door where a teacher keys the outside lever to secure the room, the K561 is the function match; the CE-109 belongs on offices and entry doors.
18) What lever styles and finishes does the Falcon K561 come in?
Three lever designs, Avalon (A), Dane (D) and Quantum (Q), each in 626 satin chrome or 613 oil rubbed satin bronze. Every lever and finish pairing is offered against every cylinder option, so matching the K561 to a corridor already running 626 levers is a straight selection rather than a special order.
