The 300TB-IP Paging Horn with Talk-Back can be used for: standard one-way SIP endpoint paging, two-way conversations via SIP endpoint paging, one-way multicast paging, and making standard or emergency two-way SIP calls initiated from the optional auxiliary switch input. The microphone enables talk-back and also monitors room noise to automatically increase the speaker volume when necessary. An optional auxiliary switch input allows a hard wired button or switch to initiate a SIP call. The button can be mounted on the wall or concealed under a desk, etc. A momentary button press will initiate a standard call, while holding the button for 3 or more seconds will initiate an emergency call. The 300TB-IP features a high efficiency 6 Watt class D amplifier capable of driving the horn at up to 113 dB SPL at 1 meter.
