The 300TB-IP-EWP 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-EWP features a high efficiency 6 Watt class D amplifier capable of driving the horn at up to 113 dB SPL at 1 meter.
The 300TB-IP-EWP is equipped with Enhanced Weather Protection (EWP), ideal for outdoor installations where the unit is exposed to precipitation or condensation. EWP products are designed to meet IP66 standards and may feature foam rubber gaskets, sealed connections, gel-filled butt connectors, as well as potted circuit boards with internally sealed, field-adjustable trim pots and DIP switches for easy on-site programming.
