An aircraft rescue fire fighting vehicle comprises a chassis module, a cab module,
and a control system. The control system further comprises a plurality of input
devices, a plurality of output devices, a plurality of interface modules, and a
communication network. The plurality of interface modules is distributed throughout
the fire fighting vehicle and are coupled to each other by way of the communication
network. The plurality of interface modules are each coupled to the plurality of
input devices and output devices. The plurality of interface modules are operative
to control the output devices based on input status information from the plurality
of input devices. Some of the plurality of interface modules are mounted on the
chassis module and other ones of the plurality of interface modules are mounted
on the cab module. The cab module is mounted on top of the chassis and is modular
in construction such that the cab module is mounted on top of the chassis module
as a substantially complete stand-alone unit.
