Fire WAN System Architectures

This section illustrates a full set of examples of valid Desigo CC architectures with Fire WAN networks.

Fire WAN Components

The Fire WAN networks can include the following units:

  • FireFinder XLS fire control panels and XLSV voice control panels, compliant with UL 864 9th edition and supported with full control from management stations (RGD mode) in Local FSI mode.
  • Desigo Fire Safety Modular and Cerberus Pro Modular fire control panels. compliant with UL 864 10th edition and supported with full control from management stations in Local and Global FSI mode.
  • Desigo Fire Safety Modular and Cerberus Pro Modular voice control panels, compliant with UL 864 10th edition and supported in monitor-only from management stations in Local and Global FSI mode.
  • Fire WAN Enclosures equipped with HUB-4 interface modules and optionally combined with a fire control panel.
  • Desigo CC management stations.

NOTE: For Zeus and firmware compatibility, see Fire WAN Limits and Compatibility.

Fire WAN Connections and Structure

The figure below illustrates the supported Fire WAN connections with the internal element structure.
The example includes:

  • WAN Enclosure connected to a fire control panel in Local FSI mode (Building 1).
  • WAN Enclosure connected to an XNET in Global FSI mode (Building 2).
  • Combined WAN Enclosure and fire control panel (Building 3).
  • Combined WAN Enclosure and fire control panel with an XNET (Building 4).

 

 

Stand-Alone Station Architecture

In single-station systems, the Fire WAN HUB-4 Enclosures are connected to a stand-alone management station via HNET.

Fire networks connections can be Modem, RS-485, or fiber.

HUB4 RS-485 line: Style 4/Class B or Style 7/Class X

HUB4 Modem line: Style 4/Class B

HUB4 RS-485 over Fiber in Single Mode (Style 4/Class B) or Multi Mode (Style 7/Class X)

XNET RS-485: Style 4/Class B or Style 7/Class X

NOTE: Style 4/Class B = DCLB; Style 7/Class X = DCLC

Client/Server Architecture

In client/server solutions, the HNET connection is implemented on the server station that provides communication services to client stations.
Multiple Fire WAN Enclosures can be wired in series on the same HNET. However, this is not recommended for heavily loaded WAN enclosures.
You can use a distributed architecture, as illustrated further below for large architectures.

The management stations and the Ethernet switch must be within 20 feet of each other, and copper network cables must be mechanically protected by UL 864 / ULC S527-compliant conduits.
A listed switch must be used. A fiber connection between stations is also possible via a listed fiber switch.

NOTE: Style 4/Class B = DCLB; Style 7/Class X = DCLC

Client/Server/FEP Architecture

Larger client/server solutions may include Front-End Processor (FEP) stations to connect Desigo CC to the Fire WAN as well as XNETs.

XNET RS-485: Style 4/Class B or Style 7/Class X

NOTE: Style 4/Class B = DCLB; Style 7/Class X = DCLC

Local and Wide-Area Fire System

XNET and Fire WAN networks can be both connected to Desigo CC server or FEP stations in a combined fire system

XNET RS-485: Style 4/Class B or Style 7/Class X

NOTE: Style 4/Class B = DCLB; Style 7/Class X = DCLC

Distributed Fire WAN Systems Architecture

Large-size solutions may include multiple local systems in a distributed architecture.
This allows to support multiple HNET Fire WAN connections, as each system can handle one connection

Each local system is based on a project, and multiple projects can be deployed to one or more interconnected server computers.
The client stations can access data from all projects.

Redundant Server and Enclosure

Desigo CC provides the "redundancy" concept. ln this concept, a duplicate server exists, and all infrastructure and hardware between the Desigo CC and the panels must be duplicateci. ln

addition, each panel is aware of and communicated in parallel to 2 independent WAN connections.

For WAN, the Redundancy concept is both costly and disadvantageous, as the WAN Enclosure must be fully duplicated, and duplicate communication lines must exist to each remote panel. Therefore, the Redundancy workaround on Desigo CC is not practical for WAN.
