A new addition to Viking Electronics’ line of VoIP paging speakers is the model 22TB-IP Talk-Back Speaker. This 2′ x 2′ drop-in ceiling tile IP speaker enables two-way conversations and end point paging via SIP, yet also allows for standard paging and background music via multicast (can receive up to 10 multicast paging streams). As an added benefit it can also make standard and/or emergency SIP calls.
The 22TB-IP easily connects with a single CAT5/6 cable from a PoE switch. Its size, shallow depth, and lightweight design make for a quick and easy installation in drop/suspended ceilings. The Talk-Back Speaker’s white grill blends in with existing ceiling tiles and air vents.
An auxiliary switch input allows for a hard wired wall mounted button to initiate a SIP call. A momentary button press will initiate a standard call, and holding the button for three or more seconds will initiate an emergency call. The integrated high sensitivity microphone enables talk-back and also monitors room noise to automatically increase the speaker volume when necessary. Line level audio output connections are provided for connecting to an external amplifier. The 22TB-IP has an integrated 6 watt amplifier allowing its speaker output connections to directly drive up to five additional 8 Ohm speakers or horns. An on-board form-c relay contact can be programmed using the included IP Programming software to trigger a strobe light, door strike, doorbell, external amplifiers, etc. A programmable blue status LED is provided to indicate paging, SIP call, and network registration.
The 22TB-IP Talk-Back Speaker drop mounts into 2 x 2 or 2 x 4 suspended ceilings. A heavy-duty back box protects speaker and circuitry against plenum dust. Operating temperature is -40°F to 140°F (5% to 95% humidity, non-condensing).
