An audio network contains one node with an audio controller module
(4100-1210 Analog Controller Board or 4100-1211 [or -1311] Digital Controller Board), and local
analog or digital amplifiers. Some configurations may have an audio controller module located in
a transponder end node; for example, an application with backup local audio in a non-head end
node or an application with distributed microphones.
Typically, the other nodes only contain amplifiers, the audio riser interface (a 4100-0621 Analog
Audio Riser, a 4100-0622 Digital Audio Riser or a 4100-1341 MCC Digital Audio Riser), and the
4100-0623 Network Audio Riser Controller Module.
The 4100-0623 Network Audio Riser Controller Module supports audio interconnections when
connected to 4100-0621 Analog Audio Risers, 4100-0622 Digital Audio Risers or 4100-1341
MCC Digital Audio Risers. It is a version of the Basic TIC that doesn’t have RUI input. It
communicates via internal communications and is used to control audio riser interface modules in
network nodes that are stand-alone fire alarm control panels.
Figure 2 shows DIP switch, LED, and connector locations on the 4100-0623 Network Audio Riser
Controller Module.
