FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The MOM2-XMP is used in CAB1, CAB2, and CAB3 enclosures
for mounting MOM-2 modules. A MOM2-XMP mounts in one
position on a CAB-MP system mounting plate.
The NIC-C is a card that provides HNET or XNET and CAN network
communication. The HNET/XNET network can be wired either Style 4 or
Style 7 . For HNET one NIC-C is required in each enclosure. For XNET one
NIC-C is required per system. This NIC-C must be installed in the same
enclosure as the PMI/PMI-2/PMI-3. Each NIC-C occupies one HNET
address. The CAN network can be isolated within a given enclosure or
extended external to the enclosure. External CAN networks require either
an RNI, OCM-16 or SIM-16 in the remote enclosure. The CAN address of
the NIC-C does not need to be set.
In Canada, ULC S524 requires that all interconnecting data communica-
tions links for networks be wired DCLC (style 7) except for dedicated
network communication to annunciators.
The NIC-C supervises the network to insure proper operation. Any faults
that are detected by the NIC-C are reported to the PMI/PMI-2/PMI-3 for
annunciation. In addition, the NIC-C has diagnostic LEDs that indicate which faults
have been found. Individual LEDs are included for Loop A and Loop B faults, as well
as an LED for complete failure of the network. The NIC-C can also be configured to
perform ground fault detection on the network.
The NRC Network Ring card connects FireFinder-XLS panels together to form a Class
X (Style 7) ring. The NRC can also be configured for Class B (Style 4) operation in
panels where a ring is not required as an alternative to the NIC-C card.
In Canada, ULC S524 requires that all interconnecting data communica-
tions links for networks be wired DCLC (style 7) except for dedicated
network communication to annunciators.
