BACnet Gateway-3 Installation and Operation Manual - P/N: 53372:Rev: A 5/6/09
Section 1 NOTIFIER® BACnet Gateway-3 Features
1.1 Product Description
The NOTIFIER® BACnet Gateway-3 (BACnet GW-3) provides a communication link between
networks that use the BACnet communication protocol and Fire Alarm Control Panels (FACP)
resident on an NFN network or high speed NFN network. The BACnet GW-3 acts like any other
node on an NFN network or 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 BACnet GW-3 application represents physical fire devices as BACnet objects and manages the
object database. As events occur, the object properties are updated in real-time, and messages are
sent to the appropriate BACnet report destination (BACnet computer clients are computers with the
graphical user interface workstation front end). 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.
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. For details, refer to
Appendix A, “PIC Statement”, on page 41
The BACnet GW-3 Configuration Tool, an offline programming utility that is included with the
BACnet GW-3 assembly when ordered, is used to configure the BACnet GW-3. It is installed onto
a computer that will be used to configure the gateway. Refer to
“BACnet GW-3 Configuration” on
.

Tool.
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.
