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