Functions (continued)

Mortise Cylinders — Interchangeable Cores

All Falcon MA Series keyed locks are available with mortise cylinders that will accept Falcon small format

interchangeable cores (SFIC) as well as some other manufacturers’ SFIC. Interchangeable core cylinders are

available in 6- or 7-pin conﬁgurations, for increased security by quick change of keying.

Interchangeable core cylinders allow the capability of immediately changing the keying on any door without

the necessity of disassembling the lock. The core is removed by use of a special “control” key. Rotating the key

to the right and gently pulling will disengage the core from the housing. The replacement core is then inserted

and the control key rotated to the left to “lock” the core in place and the control key is removed.

To order: Falcon mortise locks with interchangeable cores, add “G” 6- or 7-pin in detail area of order.

To order: Falcon mortise locks for interchangeable core, less core (SFIC), add “B” 6- or 7-pin in detail area of order.

All keyed cylinders are supplied with

two nickel silver keys.
