Total Building Solution Architectures with XNET

Total Building Solution (TBS) architectures include both Fire as well as Building Automation (BA) and Video networks to provide for a complete building management.

As for Desigo CC, these architectures can be implemented with stand-alone management stations and client/server systems, possibly including web-based remote connections. The possible configurations are presented in the following examples.

TBS architectures can include single or multiple fire networks.

As far as multiple network connections are concerned, beyond the overall system limits, the same rules, limits, and principles apply on each connection as for the single-network architectures.

NOTE: No Request/Grant/Deny (RGD) mechanism can occur to exchange control between local management stations. For each ULC-compliant fire network, the control on the fire system is assigned to the management station associated to the local control panel that has the control on the voice system.

TBS Management Station Architecture with Fire Networks and Video

Desigo CC can support a video network connecting IP cameras along with a fire system.

The fire section of the system must comply with the UL 864 / ULC S527 requirements, whereas the video network can include any network components.

Compliant fire stations can provide for video functions, and additional client stations that are not part of the approved system can be added to support BA and video functions.
Fire system information can be seen on such stations, but no fire control commands can be executed.

TBS Management Station Architecture with Fire, BA, Modbus, and Video Networks

A multi-protocol building automation network can also be included and connected to the same Fire and Video server.

The fire section of the system must comply with the UL 864 / ULC S527 requirements, whereas video and BA networks can include any network components.

Compliant fire stations can provide for building automation and video functions, and additional client stations that are not part of the approved system can be added to support BA, Modbus, and video functions.
Fire system information can be seen on such stations, but no fire control commands can be executed.

TBS Management Station Architecture with Web Stations and Fire, BA, and Video Networks

A web server station can provide a web-based access to remote stations. On the web-based clients, the user interface is implemented by active web pages and communication is based on web protocols.

These additional stations are not part of the UL 864 / ULC S527-approved systems and can be added for displaying (not commanding) the fire system and supporting other functions.

Comprehensive Multi-discipline TBS Management Station Architecture

The following image presents a comprehensive TBS solution, including fire networks, video, building automation, and Modbus.
In this architecture, the list of stations includes the system server, enhanced by a BACnet FEP for building automation and by a web server, and various client, web-based, mobile (on Wi-Fi devices), and OPC client stations.
