Can a thumbturn cylinder be used on the L9453?

A thumbturn cylinder will not provide the intended operation.  The L9453 requires the actual thumbturn hub to be rotated the additional 20° to unlock the outside lever once the deadbolt has been thrown. The thumbturn cylinder (or the keyed cylinder) do not allow for the extra rotation of the thumbturn hub. Thus, once the deadbolt is thrown, the outside lever will be locked and neither the outside keyed cylinder nor the inside thumbturn cylinder will be able to unlock the outside lever.
