Product Details

The Viking model 22TB-IP Talk-Back 2 x 2 ceiling tile replacement speaker enables two-way conversations and end point paging via SIP, yet also allows for standard paging and background music via multicast. The Talk-Back Speaker easily connects with a single CAT5/6 cable from your PoE switch. Its 2’ x 2’ size, shallow depth and light weight design make for a quick and easy installation in drop/suspended ceilings. The speaker’s 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 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 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 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.
