Section 8: The Bacnet Feature - Honeywell HON-CGW-MBB Installation And User Manual

The BACnet feature of the CLSS Gateway provides communications between a network
using the BACnet communication protocol and the gateway's FACP(s) in an NFN network
or high-speed NFN network.
The CLSS Gateway acts like any other node on an NFN network or a high-speed NFN
network. The NFN network communicates with the gateway through an HS-NCM-
W/SF/MF or NCM-W/F network control module that is on that NFN network or through a
direct connection to a single NOTIFIER® panel. The BACnet communication protocol is
an American National Standard (ANSI/ASHRAE 135-1995).
The CLSS BACnet client will present the physical fire devices in the network as BACnet
objects. The CLSS Gateway manages their object database. As events occur, the object
properties are updated in real-time, and messages are sent to the appropriate BACnet
report destination.
NOTE: The BACnet computer clients are computers with a graphical user interface
workstation front-end.
The BACnet clients may make requests to read properties of the BACnet objects. Those
properties are the values of the device status and programming.
The user subscribes to Event Notification objects per FACP, and the BACnet device
receives events from objects on the FACP as a result of this subscription. Large networks
can use multiple gateways (greater than 15 panels/15,000 objects).
The BACnet client workstation front-end must conform to BACnet Standard Annex J for IP
and support Device Objects, Binary Output Objects, and Multi-state Input or Life Safety
Points/Zones. It is also required to write to Notification Objects and receive
confirmed/unconfirmed event notification messages.
CLSS Gateway is configured through CLSS App and CLSS Site Manager. For information
about configuration, refer to
NOTE: This manual is written with the understanding that its user is trained in BACnet
operations and services. The information provided here is solely for the configuration of
the Gateway to communicate event information to an existing BACnet network.
