Simplex 4100-0622 (assembly 742-535) is a 3 to 8 channel digital audio riser module with NAA input for Simplex 4100ES emergency voice/alarm systems. It receives and decodes digital audio inputs for up to eight audio channels, so remote transponders can select and amplify the channels sent over the digital riser.
The riser signal is reformatted and repeated at each module, allowing up to 2,500 ft between the digital controller and the first riser module and up to 2,500 ft between modules. The NAA input accepts 25, 70.7 or 0.707 VRMS.
