Falcon X561LD EG 626 – Frequently Asked Questions

1) What does classroom function actually do on the Falcon X561?
It is an ANSI F84 classroom lock. The outside knob is locked and unlocked by key only, the inside knob always retracts the latch for free egress, and there is no inside button or turn, so a student cannot lock the door from inside. It is a single cylinder lock, keyed on the outside only.
2) Can the Falcon X561 go on a fire rated classroom door?
Yes. The X561 is UL Listed with a 3 hour A label rating, which covers it for fire door assemblies up to that rating. Pair it with a fire rated latch and frame prep and the opening stays compliant.
3) Can I order the Falcon X561 less cylinder so I can drop in my own SFIC core?
Yes. The cylinder choice is Conventional 6-Pin Cylinder, Less Cylinder, or Less Small Format Interchangeable Core (Less SFIC). Take Less SFIC if you are supplying your own small format core, and set the keyway selection to None (Select for Less Cylinder Options) when you order that way. Falcon's interchangeable cores are compatible with SFIC products from other manufacturers, so an existing SFIC key system can carry over.
4) Which keyways can I get the Falcon X561 keyed to?
Falcon G (standard), Schlage C, plus E, H, K, L, N and P. Schlage C matters if the building is already on a Schlage C master system, since it lets the X561 fall under the existing keying instead of forcing a second key. Keying can be specified keyed different or keyed alike, with a key code entered on the order.
5) If the door needs a storeroom function instead of classroom, what Grade 1 knob lock should I use?
The Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a single cylinder and a 2-3/4 inch backset, the same backset the Falcon X561 uses. Storeroom keeps the outside knob locked at all times and the key retracts the latch without leaving it unlocked, where the X561 classroom function lets a key lock and unlock the outside knob and leave it that way. Choose by how the room is meant to be secured, not by grade, since both are Grade 1.
6) What is a Grade 2 classroom knob lock alternative to the Falcon X561?
The Dexter C2000 Series classroom cylindrical ball knob lock is a keyed classroom function knob lock built to Grade 2 and fitting doors 1-3/8 inch to 1-3/4 inch thick. The Falcon X561 is a Grade 1 heavy duty classroom cylindrical lock that covers a wider 1-3/8 inch to 2-1/4 inch door thickness range. Both give you the classroom function where the outside knob is locked and unlocked by key; the difference is the ANSI/BHMA grade and the door thickness span.
7) Is the Corbin Russwin CK4851 a substitute for the Falcon X561?
Not function for function. The CK4851 is a Grade 1 entrance/office cylindrical knob lock with a conventional cylinder, fitting doors 1-3/8 inch to 2 inch. The Falcon X561 is classroom function and accepts an interchangeable core or can be ordered less cylinder or less SFIC, and it fits doors up to 2-1/4 inch. If your key system is built around small format interchangeable cores, the X561 is the one that drops into it; the CK4851 as listed is a conventional cylinder lock in a different function.
8) Our doors are thicker than 1-3/4 inch - which knob locks besides the Falcon X561 will fit?
The Falcon X561 covers 1-3/8 inch through 2-1/4 inch, the widest of the commercial knob locks in this group. Corbin Russwin CK4851 and CK4310 go to 2 inch, and the Schlage A170 dummy trim goes to 1-7/8 inch. Most of the Grade 2 and Grade 3 knob locks, including the Dexter C2000 series and the Pamex FTF Baron, stop at 1-3/4 inch. For a 2 inch or thicker leaf with a classroom function requirement, the X561 is the fit.
9) Is the Falcon X561 tough enough for a high traffic school corridor?
It is certified ANSI/BHMA A156.2 Series 4000 Grade 1, the heavy duty commercial tier, and is built with brass or cold-formed steel parts with a zinc dichromate coating. The roses are heavy wrought brass, bronze or stainless over steel through-bolted rose inserts, which is what keeps knobs from working loose on a door that gets hit hundreds of times a day.
10) Is there a cheaper classroom knob lock than the Falcon X561 for a light traffic door?
The Dexter C2000 Series classroom cylindrical ball knob lock is a Grade 2 keyed classroom alternative, fitting doors 1-3/8 to 1-3/4 inches. Note the narrower thickness range: if your door runs over 1-3/4 inches, the X561 at 1-3/8 to 2-1/4 inches is the one that fits. Grade 2 is the medium duty tier, so for a corridor door that cycles all day the Grade 1 X561 is the right call.
11) For the non-keyed doors in the same corridor, what Grade 1 knob matches the Falcon X561?
The Schlage D10S passage latch is a Grade 1 heavy duty non-keyed cylindrical knob lock with an Orbit knob, which keeps the passage doors at the same grade and duty level as the Falcon X561 classroom lock on the keyed openings. The X561 is keyed with a single cylinder; the D10S has no cylinder and the knobs always turn. Corbin Russwin CK4310 is another Grade 1 passage/closet knob, rated for doors 1-3/8 inch to 2 inch.
12) We need the same Grade 1 knob on an office door that locks from inside with a button - what takes the place of the X561 there?
The BEST 8K Series entrance function single cylinder knob lock is a Grade 1 heavy duty knob lock in the entrance function, which is the usual choice for an office door that gets locked at the knob rather than only by key from the corridor. The Falcon X561 is the classroom version of that same duty class, Grade 1 heavy duty with a single cylinder, keyed only from the outside with no inside locking button. Keeping the entrance doors on 8K and the classroom doors on X561 keeps both at Grade 1.
13) What looks like a Falcon X561 substitute but is only trim, not a lock?
The Sargent 28C-KNOB is exit device trim with a knob and rose for 1-3/4 inch doors, and the Sargent 78-2875 is an outside knob only. Neither contains a latch or a chassis - they mount to an exit device or replace a knob on an existing lock. The Falcon X561 is a complete cylindrical classroom lockset with its own chassis, latch and ANSI strike, 1-1/4 inch by 4-7/8 inch with a square curved lip corner. If you are replacing a lock in a bored door, take the X561, not the trim.
14) What finishes does the Falcon X561 come in for matching existing door hardware?
Six: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome and 630 satin stainless steel. For most schools and offices the existing standard is 626 satin chrome or 630 satin stainless.
15) Does the Falcon X561 come with lever trim, or is it knob only?
It is a knobset. The trim choices are the Elite, Hana and Troy designs, each in a Gala or York variant (EG, EY, HG, HY, TG, TY). If your facility requires lever operation for accessibility, a knob is not the right selection here.
16) We need matching dummy trim for inactive leaves next to X561 classroom doors - what knob dummy is available?
For a commercial opening, the Schlage A170 single dummy trim is a Grade 2 heavy duty non-keyed cylindrical knob dummy for doors 1-3/8 inch to 1-7/8 inch, and the BEST 6K Series single dummy trim is a Grade 2 medium duty knob dummy. Dummy trim has no latch and no chassis, so it only suits a fixed or inactive leaf; the Falcon X561 is the keyed classroom lock for the active leaf.
