The model TWK351 is an adapter used in instances where there is existing 2-conductor shielded wiring. The TWK351 cannot be used with the SCR25A module. If 3- wire operation using the TWK351 wire converter is desired, CA10A call switches must be used (CA11A Callin switches will not work in this application). The TWK354 is a 3-transformer assembly only used for 2233 systems.
