The TA303I is used on intercom systems using the NH200A (or similar) intercom amplifier. The TA309I is used on intercom systems using the NH209TT (or similar) intercom amplifier. The TA330I is used on intercom systems using the Elvox type speaker/microphone.

All units feature a heavy duty ABS (Black) pay-phone style handset mounted onto an AM190 aluminum panel module, with an 'armor' cord and metal dead hook style handset cradle. The internal speaker/microphone components installed into these handsets is determined by the intercom amplifier with which the handset will be utilized.
