Guardian Telecom
EXP-TBA Explosion Proof Talk/Back Stations provide communications in harsh, industrial environments and hazardous areas. They provide easy to operate paging with the versatility of a hands free slave speaker.
The EXP-TBA has total system flexibility in order to adapt to station location, with the use of either internal microphone & faceplate PTT switch or master speaker as microphone & remote PTT switch.
A post announcement tone can be programmed (internal) to indicate end of page from master station to the slave speaker. An optional switch can be wired at the slave speaker to activate a ring signal at the master station to request communication.
