Section 8: The BACnet Feature
The BACnet feature of the CGW-MB provides communications between a panel(s)
network and a BACnet client, which is using the BACnet communication protocol.
The CGW-MB acts like any other node on a panel network. It can communicate with a
single panel or network of panels directly or through a network control module.
The CLSS BACnet client will present the physical fire devices in the network as BACnet
objects. The CGW-MB 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.
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 CLSS Gateway mainboards (greater than 16 panels with a combined
maximum of 15,000 objects).
The BACnet client workstation front-end must conform to
BACnet Standard Annex J
