Product Details

The Viking model 22TB-IP Talk-Back 2′ x 2′ ceiling speaker tile replacement enables two-way conversations and end point paging via SIP, yet also allows for standard paging and background music via multicast. The Talk-Back Ceiling Speaker easily connects with a single CAT5/6 cable from your PoE switch. Its 2’ x 2’ size, shallow depth and lightweight design make for quick and easy installation in drop/suspended ceilings. The paging ceiling speaker aesthetically pleasing 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 paging call. A momentary button press will initiate a standard call, and holding the button for 3 or more seconds will initiate an emergency call. The integrated high sensitivity microphone enables talkback paging and also monitors room noise to automatically increase the overhead ceiling 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 ceiling speaker output connections to directly drive up to 5 additional analog speakers. A programmable relay output is provided for activating door locks, strobe lights, external amplifiers, etc. A programmable blue status LED is provided to indicate paging, SIP call, and network registration.
