Falcon A12689-000-00 – Frequently Asked Questions

1) Will a Falcon SFIC tailpiece pack work on a full size interchangeable core rim cylinder?
No. The A12689-000-00 is built for small format interchangeable core (SFIC) rim housings only. SFIC and FSIC cores have different figure-eight geometry and different tailpiece drivers, so an FSIC rim housing needs its own parts. If you are actually working on full size interchangeable core hardware, a complete FSIC rim cylinder such as the Schlage Commercial 20-057 with its convertible tailpiece cam is the part that does the job.
2) If the Falcon rim housing itself is damaged rather than just the tailpiece, what complete rim cylinder can go in instead?
The Falcon A12689-000-00 is a tailpiece pack only - it supplies the tailpiece components that interface an SFIC core with a Falcon rim housing, so it does nothing for a housing that is cracked or worn. For a whole rim cylinder replacement, the Corbin Russwin 3070 is a 6-pin rim cylinder housing supplied with a 1-7/8 inch tailpiece, and Schlage offers the 20-021 rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam, each with 6 pins and two keys. Match the tailpiece orientation and length to what your rim exit device requires.
3) Does the Falcon A12689-000-00 include an interchangeable core, or do we order the core separately?
The A12689-000-00 supplies tailpiece components for joining an SFIC core to a Falcon rim housing - the keyed core is a separate line item. BEST small format cores that serve that role include the 1C Series standard 5-pin cylinder core, the Peaks 1CB 150 Series interchangeable core, and the 1CDF drill resistant patented 7-pin brass core in the 150 Series. Order the core in your facility's keyway and keying so it can be pinned into your existing master key system.
4) Our building uses full size interchangeable cores, not SFIC - what rim cylinder should we use?
The Falcon A12689-000-00 tailpiece pack is built for Small Format Interchangeable Core systems, so it is the wrong interface for an FSIC key program. For full size interchangeable core openings, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is an FSIC core in the Schlage C keyway with a 643E aged bronze finish. Confirm which of the two you need - one is the rim housing assembly, the other is the core that drops into it.
5) I manage a building on an SFIC master key system. Does replacing the tailpiece mean rekeying?
No rekeying is involved. On an SFIC setup the keying lives in the interchangeable core, which pulls out with a control key and drops back into the same housing. The A12689-000-00 only restores the mechanical drive between core housing and rim hardware, so your existing master key program stays intact.
6) Is this a genuine Falcon part or an aftermarket tailpiece?
It is a genuine Falcon lock part, model A12689-000-00, made for Falcon rim housing cylinder assemblies. That matters on a tailpiece more than most parts, because tailpiece length and tip geometry have to match the housing and the rim device prep exactly for the latch to retract fully.
7) My rim exit device cylinder turns but the latch will not retract. Is the tailpiece the problem?
That is the classic symptom of a worn, bent or wrong-length tailpiece on a rim housing: the core rotates but nothing drives the device. On Falcon SFIC rim housings the A12689-000-00 tailpiece pack is the service part that restores that mechanical engagement without replacing the whole cylinder assembly.
8) Can the Falcon A12689-000-00 tailpiece pack be used on a mortise lock instead of a rim device?
No. The A12689-000-00 is engineered for Falcon rim housing configurations used with rim-mounted exit and locking hardware, and mortise locks drive the latch through a cam rather than a rim tailpiece. For mortise openings, Corbin Russwin offers the 1000 Grade 1 series mortise cylinder at 1-1/2 inch with an A02 straight cam, the 1070 Grade 1 series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder with an A01 cam for Schlage L9000 mortise locks. Pick the cam style your mortise case calls for.
9) We have aluminum storefront doors with Adams Rite deadlocks - is the Falcon A12689-000-00 the right cylinder part?
It is not. The A12689-000-00 serves Falcon SFIC rim housing assemblies, which is a different platform from narrow stile storefront deadlocks. Adams Rite pairs its MS1847 deadlock/deadlatch with the 4024 cylinder pull, which mounts with a trim plate, and the 4025 five pin tumbler cylinder pull, which uses through-screws; the 4026 five pin tumbler cylinder pull is intended for wood door applications with the Adams Rite 5017 wood door deadlock/deadlatch. For a mortise cylinder on that hardware, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness.
10) What looks like a substitute for the Falcon A12689-000-00 but will not work on an SFIC rim housing?
Several rim-style cylinders read as close matches and are not. The Medeco 1065244 is a 5-pin lazy motion rim type cylinder supplied with an Emtek tailpiece, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts - all are residential-pattern rim cylinders with their own fixed tailpieces rather than SFIC interface parts. The BEST 12E Series dummy rim cylinder at 1-5/32 inch diameter is non-keyed and provides no function at all. The Falcon A12689-000-00 is the commercial tailpiece pack that mates an SFIC core to a Falcon rim housing.
11) Is the Falcon A12689-000-00 rated for commercial door hardware or is it a residential part?
Commercial. It is specified for Falcon commercial door hardware, the kind of SFIC rim applications found in offices, schools, healthcare, government buildings and multi-tenant properties running centralized key control.
12) We need to rekey knob and lever locks at the same time as the Falcon rim hardware - what cylinder handles those?
The Falcon A12689-000-00 only addresses the SFIC tailpiece connection on rim housings. For key-in-knob and lever cylinders, Kaba Ilco offers the 1539 Series universal key-in-knob/lever cylinder and the 1599 key-in-knob replacement cylinder, plus the 1579 knob and lever cylinder made for Sargent locks; the 1549 Series is a key-in-deadbolt cylinder. Detex also lists the MC65 mortise cylinder in Schlage C keyway, 1-1/8 inch, 6-pin commercial grade. Specify all of them in one keyway if you want the building keyed alike.
