TBA
Guardian Telecom TBA Talk/Back Amplifiers are designed for safe, reliable and cost-effective communication. They provide easy to operate paging with the versatility of hands-free slave speakers.
Utilizing explosion proof slave speakers, Talk/Back units are very useful in hazardous areas where hands-free communication is required.
Guardian’s TBA Talk/Back systems provide reliable point-to-point and point-to-multipoint communication in areas such as on drilling rigs between drill cabin/drill floor and monkey board, plus moon pool, mud tanks, etc.
TBA Talk/Back systems are also used extensively on ships and off-shore platforms where hands-free communication is required from slave-operator end.
