Installing a BT5 enables staff to make public address announcements from their own desk telephone by simply dialing into an allocated extension number.
The free-standing units act as an interface between the analogue telephone system and the public address system.
- 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.
