All KIRK Key Interlocks (Type F, FN, B, NT, T, U, FR)
The key interlock should be mounted so that the 5/8" lock bolt can be extended to lock the device
in the proper position. In the unlocked position, the lock bolt should be blocked from extending,
thereby trapping the key(s) in the interlock.
Multiple cylinder interlocks can be designed to retain one or more keys while the remaining keys
are withdrawn.
Key interlocks with multiple cylinders require the insertion of all keys before the lock bolt can be
extended or withdrawn allowing release of the previously held keys. Do not try to force a
multiple cylinder interlock that does not have the correct keys fully inserted in every cylinder.
