e. Remote Area Data Collectors (RADCs). (See Figures 1-26 and 1-27.) The RADC provides for local alarm inputs and
outputs and also provides extensive sub-unit capabilities. Up to 16 Intelligent Access Controllers (31 doors) can be multi-
dropped on an RS-485 line. These lines can extend out from the RADC location some 4000 feet. The CPU and memory
capability handles the global capacity that is provided by this distribution of inputs and outputs. An optional keypad
provides an interface to personnel so examination of the status can be made. A port is also provided to connect a lap
top computer for unit configuration and diagnostics. The audio interface provides the capability for the audio assessment
Input devices and the intercom. The encryption device, when required, will be installed in the RADC enclosure. Data
communications to the PMC is provided via the Mod 2 modem. A built-in UPS is also provided as part of the RADC.
