Before Connecting NIBs
Each panel should be running and free of troubles and alarms before attempting to connect to the network. When
panels are free of troubles and alarms proceed to the Panel-NIB configuration section.
Node Numbering
A total of 99 NIBs can be connected on a network. Addresses 1 thru 99 are to be used for MPC-6000, MPC-7000,
RND-2 Remote Network Displays, printers, and computers used as simple terminals to log network events.
Panel-NIB Configuration
For wiring connections refer to the installation and wiring diagrams for the 12523A or 12603A.
The following configuration data for the NIB is entered in the tech level, network options setup of the panel it is
connected to. This includes:
Enabling the network connection to the panel
Setting the Node # (1-99)
Entering the total number of nodes (1-99) on the network.
Display network LINK alarms? 1=yes 0=no (For RND-2 only)
Setting this option to 0, allows device alarms to be displayed but prevents the RND-2 from
o
displaying all of the resulting panel alarms that occur as a result of a device in a network LINK
going into alarm. This setting helps identify the specific source of the alarm on the RND-2 display
in a more timely manor. All network messages are still stored in the RND-2 event history.
The following configuration data for the NIB is entered in the tech level, system parameters setup of the panel it is
connected to.
Enable global commands? 1=yes, 0=no
Enabling global commands allows the panel to be controlled from a network annunciator i.e.; RND-2.
o
Send global commands? 1=yes, 0=no (For RND-2 only)
The NIB configuration data is passed from the panel to the NIB at power up and reset of the panel.
Printer-NIB Configuration
For wiring connections refer to the installation and wiring diagrams for the 12526A.
If a NIB is connected to a printer it must first be configured to operate in the unsupervised mode. To configure a NIB
to operate in the unsupervised mode it's RS- 232 port must be connected to a RS-232 on a computer running the
CIS-4 software version 3.00 or higher and running the NIB programming utility. After doing this, the NIB will run in the
unsupervised mode.
Computer-NIB Configuration
For wiring connections refer to the installation and wiring diagrams for the 12526A.
When using a simple terminal computer program to log network events, the unsupervised connection type must be
used. To configure a NIB to operate in the unsupervised mode its RS- 232 port must be connected to a RS-232 on a
computer running the CIS-4 software version 3.00 or higher and running the NIB programming utility. After doing this,
the NIB will run in the unsupervised mode.
Network Links
Fire alarm control panels connected together in a network are able to interact via 255 Network Links. A network link
may be visualized as a multi-state "wire or" between nodes. A network link may be an input to a panel's output Zone
map or may be controlled by the output state of an input group of a panel. This means that the status of an input
group on any panel may cause outputs on another panel to activate depending on whether the input group is an
Alarm, supervisory or trouble condition. The conceptual model for the operation of Network links is shown in the
diagram of Appendix A.
