Description
 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. |
