3.5.6 Trouble with NCS and INA Equipment
Signals originating at the NCS and INA are transmitted to other reporting nodes (i.e., NCS or
another INA) on the network. All local troubles are reported with the exception of node off-line
conditions which depend on the local settings of the NCS or INA and are reported individually by
all reporting nodes.
Below is a list of trouble messages which are exclusive to the NOTI•FIRE•NET
™
network
environment.
Node XXX Communications Failure
The node is programmed into the system but does not exist physically on the network, or the
node is physically attached to the network but is not programmed into the Command Center.
Communication Link Failure in Port A
Data is not being received on network (MIB) Port A. This trouble is only reported if the node
is configured for dual port supervision.
Communication Link Failure in Port B
Data is not being received on network (MIB) Port B. This trouble is only reported if the node is
configured for dual port supervision.
Lan Communications Failure
