CSB CAN Sounder Board The CSB is a module that contains a sounder (buzzer) that
can be used with the SCM-8 or FCM-6 to provide audible
feedback to indicate that a switch closed properly and
communication was successful. The CSB requires no
programming.
FCM-6 Control Module The FCM-6 contains six sets of three pushbutton switches and
their corresponding LEDs. The ON and AUTO switches both
have one bi-color (red/green) LED while the OFF switch has
one bi-color and one yellow LED. The functions of the switches
and LEDs are programmed using the Zeus Tool (Refer to the
Zeus Quick Start Guide, P/N 315-033875). All LEDs can be
programmed ON, OFF, or FLASHING.
HLIM Loop Isolator Module The HLIM Loop Isolator Module isolates short circuits on
FireFinder-XLS intelligent loops. By placing devices between
HLIMs during installation, a short in the wiring within that group
is disconnected from the rest of the loop. The remainder of the
devices continue to operate. The HLIM operates in both Style 6
(Class A) and Style 4 (Class B) circuits.
LCM-8 LED Control Module The LCM-8 contains eight pairs of LEDs. Each pair contains one
bi-color (red/green) and one yellow LED. The functions of the
LEDs are programmed using the Zeus Tool (Refer to the Zeus
Quick Start Guide, P/N 315-033875). All LEDs can be pro-
grammed ON, OFF, or FLASHING. These LEDs are used for fire
system status annunciation.
NIC-C Network Interface The NIC-C is a card that provides HNET or XNET and CAN network commu-
Card nication. 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 enxlosure as
the PMI. 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.
The NIC-C supervises the network to insure proper operation. Any faults that
are detected by the NIC-C are reported to the PMI 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.
