Key and Cylinder Marking
With these options, keys and/or cylinders are stamped with
the key symbol (code). This tells how the cylinder is keyed,
eliminating trial and error. Lock mix-ups during installation or
key mix-ups afterward are less likely to happen - and easier to
straighten out if they do.
For example, the symbol AA1 shown in the illustration identies
the lock to be operated by grand master key A, master key AA
and change key AA1. Upon written authorization from the
building owner to an authorized Falcon distributor, a bitting list
can be furnished for each job to translate the symbols into key
bittings. If a key is lost, a replacement key can be ordered by
number from the Falcon distributor.
Visual Key Control (VKC)
For Greater Convenience
The key symbol is stamped on the plug face or other visible
portion of the front of the cylinder. This makes identication
fast and convenient. The disadvantage is that stolen or lost
keys can be easily matched to the locks they operate. Also,
restamping cylinders when they are rekeyed results in damage to
the nish.
AA1
Concealed Key Control (CKC)
For Greater Security
For greater security, specify CKC on the cylinders. The key
symbol is stamped in a concealed location, such as the rear of
the cylinder or the side of an interchangeable core.
It is not visible to the general occupants of the building but
can be accessed by authorized personnel upon removal of the
cylinder or core.
