IP Speaker for SIP Endpoint Paging or Multicast Paging /
Background Music, and Making Standard or Emergency SIP Calls
The Viking model 40TB-IP Talk-Back Ceiling/Wall Speaker enables two-way
conversations via SIP and 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 shallow depth allows the speaker to be conveniently
mounted in a standard 2" x 4" stud wall or ceiling.
An auxiliary switch input allows a hard wired wall button to initiate a SIP call.
Alternately, an optional wireless remote call button can be used (Viking model
BTR-3, sold separately). A momentary button press will initiate a standard call, and
holding the button for 3 or more seconds will initiate an emergency call. The remote
can also be used to adjust the speaker volume. The 40TB-IP LED can be
programmed to blink when there is call activity.
The integrated 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. Speaker output
connections are also provided to directly drive additional analog speakers.
A programmable relay output is provided for activating door locks, strobe lights,
external amplifiers, etc.
