Head-End Audio
Network
Configuration
A “Head End” audio network usually contains one node with an audio controller module
(4100-1210 Analog Controller Board or 4100-1211 [or -1311] Digital Controller Board), and
may contain local analog or digital amplifiers. Some configurations may have an audio
controller module located in a non-head 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 (4100-0621 Analog
Audio Riser or 4100-0622 Digital Audio Riser), the 4100-0623 and the 4100-1341 Network
Audio Riser Controller Module.
The 4100-0623 Network Audio Riser Controller Module supports audio interconnections when
connected to 4100-0621 Analog Audio Risers or 4100-0622 Digital Audio Risers. It is a
version of the Basic TIC that doesn’t have an RUI input. It communicates via internal slave
communications and is used to control audio riser interface modules in network nodes that are
stand-alone fire alarm control panels.
