Ethernet-based fire system network
First Claim
1. A data transmission system for a facility comprising:
- a first network including;
a number of critical devices disposed within the facility; and
at least one first computer workstation operably coupled to said number of critical devices via said first network;
a second network including at least one second computer workstation; and
an isolating router coupling said first network to said second network and operable to isolate said first network from data transmission traffic in said second network.

Abstract
A data transmission system for a building or facility includes a fire control sub-network, a building automation sub-network and/or a corporate sub-network. The fire control sub-network includes workstations connected to fire control panels that are connected to fire control devices. The sub-network includes an Ethernet switch that is UL listed for fire protective signaling uses, along with the workstations. This sub-network is integrated with the building automation sub-network through an IP router that is UL listed for information technology equipment. Thus, the fire control sub-network is both electrically isolated and isolated from data transmission traffic through the building automation and/or corporate sub-networks, so that the response of the fire control sub-network is not compromised by data traffic through the other networks. In certain embodiments, building automation workstations and control devices can be included within the fire control sub-network.

14. A data communication system for a facility comprising a first network and a second network connected by a router, the first network including a first plurality of work stations, the second network including a second plurality of work stations, the first plurality of workstations including only building system workstations, the second plurality of work stations including only non-fire safety related building system workstations and non-building system workstations, and wherein the router enables communication between the non-fire related building system workstations and the first plurality of workstations, and the router is operable to disable communication between the non-building system workstations and the first plurality of workstations.
