The BT8 Single Zone Dial Up Interface is a free standing, self-powered unit.
The BT8 connects a single amplifier within the PA system to the telephone system by plugging into the extension socket where a conventional telephone would be used (the BT8 telephone jack plugs into the two-wire master socket).
The BT8 connects to the amplifier input using screened cable which must be grounded at both ends, with the correct output selectable from line to microphone level, with priority control available where required. When this extension is dialled from another handset the ringing current is detected and the BT8 will loop the line.
An acknowledging tone, and with the MIM33 optional model; a chime is sent to the caller indicating that an announcement may now be made which will be conveyed over the PA system. Once the announcement is complete and the caller's handset is replaced, the BT8 will disconnect from the PA system and release the interface extension, thus making it ready to accept another call.
