appliances, equipment for the automatic, permanent visual recording of signals; and equipment for initiating the
operation of emergency building control services. Intelligent Fire Integrator systems are permitted to be
interconnected with other systems intended to make the premises safer.
In Proprietary Receiving Unit Mode, the Intelligent Fire Integrator system supports up to 200 gateways. Multiple
NFN and Receiver gateways are supported simultaneously and can be constantly supervised and communicating with
the same workstation. They can also span the TCP/IP network and exist on multiple workstations or embedded
hardware. The choice of which gateways to use and where they should be located is application specific and should
be analyzed by a trained individual. See
