The Network Interface Board (NIB-96) is a microprocessor-controlled module that
connects slave fire alarm control panels to a master fire control panel. Typically,
NIB-96 modules are physically located in each slave control panel, which can contain 8
to 96 input/output points. This section contains board and wiring information for
connecting a NIB-96 to an AFP-300/AFP-400 control panel.
