Installing a BT5 or BT8 enables staff to make public address announcements from their own desk telephone by simply dialing into the allocated extension number.

The free-standing units act as an interface between the analogue telephone system and the PA.
 

BT5 unit:

• The BT5 will provide the user an acknowledge tone, followed by a chime (optional OPT33 fitted). A live broadcast announcement can then be made.
• Upon completion of the broadcast the BT5 will disconnect from the PA system and release the telephone extension ready to accept another call.

BT8 unit:

• Additional facility enables the user to pre-record an announcement. This reduces the risk of feedback where the telephone is adjacent to a loudspeaker.
• When connected to a telephone system with MF signalling, the BT8 enables the user to select up to eight zones via the telephone keypad.
• An internal selector determines if the recorded message is played once or twice.
