Falcon K501CP6D D 626 – Frequently Asked Questions

1) How does the push-turnbutton entrance function on the Falcon K501 actually work day to day?
The K501 is an ANSI F82 entrance function, single cylinder. Push the button on the inside knob to lock the outside lever, and the key retracts the latch from outside while the inside lever always gives free egress. Turning the button gives you hold-open locking until someone turns it back. That makes it the right pick for an office, a tenant suite door, or a back-of-house door where staff control the lock from inside. If you need the door locked at all times from the outside with no button anyone can defeat, an F86 storeroom function is the one to spec instead.
2) Can I use the Falcon K501 on a fire rated door?
Yes. The K501 is UL Listed with a 3 hour A label rating, so it is code-legal on fire door assemblies up to and including 3 hour openings, such as stair enclosures and area separation walls. Pair it with the deadlatch, since fire doors must positively latch.
3) Do I have to order the Falcon K501 handed for a left or right hand door?
No handing to specify. The K501 levers are non-handed, so one part number covers left hand, right hand, left hand reverse and right hand reverse openings. For a property manager buying a pallet of locks for a building, that means a single stocked item instead of two, and no wrong-hand returns from the field.
4) Which cylinder option should I pick on the Falcon K501, and can I key it into my existing system?
Three cylinder choices. P6 gives you a conventional 6-pin cylinder cut to the Schlage C keyway, which is the one to take if the building already runs Schlage C keys and you want these on the existing system. L ships less the 6-pin conventional cylinder, for a locksmith dropping in a mortise-style cylinder from their own stock. B ships less small format interchangeable core, for facilities standardized on SFIC where you will install your own cores. The default cylinder if you take the standard build is a 6-pin housing keyed 5-pin in the Falcon G keyway, keyed different.
5) I need a classroom or storeroom lock, not an entrance lock. Is the Falcon K501 the wrong one?
Yes, wrong function. The K501 is entrance function with a push-turnbutton on the inside, so anyone inside can lock or unlock the outside lever without a key. A classroom door needs a key-locked outside lever that cannot be buttoned open, and a storeroom door needs the outside lever locked at all times with the key retracting the latch. Look at the Cal-Royal Barrington BA03 for classroom (ANSI F84) or the BA05 for storeroom (ANSI F86 with a deadlocking latch). The BA04 is communicating function, ANSI F80, for a door between two occupied spaces.
6) Is the BEST 9KW a drop-in replacement for the Falcon K501?
No. The BEST 9KW is an electromechanical cylindrical lock with remote control operation, meaning it needs power and a control path back to an access system. The Falcon K501 is a mechanical lock with no electronic component, keyed with a single cylinder and locked by push-turnbutton. Both are heavy duty cylindrical locks, but swapping to the 9KW turns a purely mechanical opening into a wired one.
7) I need a classroom or storeroom lock instead of an entrance lock - what do I order?
The Falcon K501 is an entrance function lock with push-turnbutton locking, so it is not the right function for a classroom or storeroom opening. The Cal-Royal BA05 is a storeroom lock with a Grade 2 ANSI F86 deadlocking latch, and the Cal-Royal BA03 is a classroom lock with Grade 2 ANSI F84 function. Both are specified for doors 1-3/8 inch to 1-3/4 inch thick.
8) Is the Falcon K501 strong enough for a high traffic door that gets abused?
It is certified ANSI/BHMA A156.2 Series 4000 Grade 1, heavy duty, which is the top cylindrical grade and what a school, hospital or municipal building should be specifying. Two things carry that in the hardware: the chassis is through-bolted with four screws so the lock clamps the door rather than relying on the bore, and the lever clutches, meaning someone hanging on or kicking a locked lever spins it free instead of loading the chassis. Substrate is brass or steel, zinc plated and dichromated for rust resistance, with stainless steel springs.
9) What is the difference between the Falcon K501 and the Cal-Royal BA00 entrance lock?
Both are turn/push button entrance function cylindrical locks, but they sit at different duty levels. The Falcon K501 is Grade 1 heavy duty and takes doors from 1-3/8 up to 2-1/4 inches thick. The Cal-Royal BA00, from the Barrington BA Series, fits 1-3/8 to 1-3/4 inch doors only. If your doors run thicker than 1-3/4 inches, or the opening needs Grade 1, the K501 is the one that fits. For a standard 1-3/4 inch interior door in a lighter-traffic building, the BA00 covers the same function.
10) What other Grade 1 clutched entrance locksets could I use instead of the Falcon K501?
TownSteel gives you the closest cross-brand equivalents. The CDC-109 is a Grade 1 heavy duty clutched cylindrical lockset in entry/office function, the same clutching approach as the K501. The CEC/CECI-109 is the clutched extra heavy duty version in the CEC Series if the opening is genuinely abusive. The CE/CEI-109 is extra heavy duty but non-clutched, which matters: without a clutch the lever transmits force straight into the chassis when it is locked, so on doors that get kicked or hung on, stay with a clutched lock.
11) Can I standardize the Falcon K501 across a whole building on one key system?
Yes, and the cylinder options are what make that practical. Take P6 and the locks come cut to the Schlage C keyway, so they fold into an existing Schlage C masterkey system without rekeying. Facilities running small format interchangeable cores take the B option, which ships less SFIC so your own cores go in, from Falcon or another SFIC manufacturer. Keying is a required selection at order, with a key code field for matching an existing system. Since the lock is non-handed and spans 1-3/8 to 2-1/4 inch doors, one item covers nearly every opening in a mixed-age building.
12) What is the difference between the TownSteel CE-109 and CEC-109 versus the Falcon K501?
All three are Grade 1 heavy duty entrance-function cylindrical locksets. The CEC-109 is an extra heavy duty clutched lockset and the CE-109 is an extra heavy duty non-clutched lockset, so the CE-109 lever stays fixed to the chassis when locked. The Falcon K501 uses a clutching lever, letting the lever move while locked without unlatching the door. All three suit entry or office openings; the choice comes down to whether you want the lever to spin under abuse or stay solid.
13) Can I use the TownSteel CRX-A-41 in place of a Falcon K501?
Only where the door does not need to latch. The CRX-A-41 is a single dummy trim - a stainless steel ligature resistant arch trim lockset with no keyed or latching function - and it is specified for 1-3/4 inch doors. The Falcon K501 is a keyed entrance lock with a single cylinder that latches and locks the door. Use the CRX-A-41 on an inactive leaf or pull-only door, and the K501 where the opening has to secure.
14) For a fire-rated opening, which of these entrance locks is the one to specify?
The Falcon K501 carries UL10C 3 hour A label listing and is certified ANSI/BHMA A156.2 Series 4000 Grade 1, which is what a fire-rated commercial opening needs on the schedule. Among the entrance-function alternates, the TownSteel CDC-109 and CEC-109 are both Grade 1 heavy duty clutched entry/office locksets, while the Cal-Royal BA00 entrance lock is the lighter-duty Barrington option for 1-3/8 inch to 1-3/4 inch doors.
15) If I am standardizing a building on one entrance lock, does the Falcon K501 or the Cal-Royal BA00 cover more openings?
The Falcon K501 spans doors 1-3/8 inch to 2-1/4 inch thick and is non-handed, so one part number covers thin and thick leaves and both swings. The Cal-Royal BA00 entrance lock is specified for 1-3/8 inch to 1-3/4 inch doors, so a facility with thicker leaves would need a second solution alongside it. The K501 also accepts conventional cylinders and small format interchangeable cores including the Schlage C keyway, which helps when the site is already keyed.
16) Which lever styles and finishes does the Falcon K501 come in?
Three lever styles, Avalon (A), Dane (D) and Quantum (Q), each in 626 satin chrome or 613 satin bronze oil-rubbed. Every lever and finish combination is built, so you can run Quantum levers in 626 through the corridors and 613 on the front-of-house doors without changing lock model. 626 is the usual commercial default and the easiest to match to existing hinges and closers.
