The basic version of the 4100U-S1 is used for smaller or single-building applications. It is
ideally placed in a small building that requires a limited number of notification appliances
and initiating devices.
If a small building is being expanded, or if other buildings are being constructed in the
same general area (as in a campus application), the basic 4100U-S1 can be expanded via
networking into one of the larger systems described in Chapter 3.
The basic 4100U-S1 is a single cabinet containing these items: CPU, System Power
Supply, and optional slave cards.
As standard, the 4100U-S1 has one IDNet addressable loop that can support up to 250
devices. A second IDNet addressable loop can be added by fitting a 4100-3101AU IDNet
module to the expansion bay in the cabinet (see Chapter 6).
The basic 4100U-S1 can be expanded with a limited number of 4100-type legacy
card/modules or newer 4” x 5” 4100U modules.
All appliances and devices are connected to this one cabinet, as shown in
Figure 1-1.
