HUB-4 Communication
Card
P/N 315-099458-9
The Model HUB-4 Communication Card from Siemens Industry, Inc., mounts in the
CC-5 Card Cage and provides up to four independent data channels, which can be
wired as either Style 4 or Style 7 for communication to the remote XLS, MXL, XL3 or
other UL864 listed local fire alarm panel providing dry relay contacts that can be used
for event monitoring.
The HUB-4 consists of a single Main-2 board on which two COM-2 boards are
installed. In turn, up to two modem or RS-485 Interface blocks can be installed on
each COM-2 board. Each modem block installed provides a single FSK data channel.
Each RS-485 Interface block installed provides a proprietary RS-485 interface channel.
Either a RS-485 Interface or a Modem Block module can be used, dependent on
application. Table 1 describes the connections that can be made.

Each of the four data channels is controlled by a separate micro-controller which
provides all background supervision of the data lines (to the remote panel) as well as
sending and receiving Fire Panel information to the primary micro-controller. The
information from these four channels is concentrated into a single data stream and
sent to the NCC WAN via the NIC-C or the PMI-2 Concentrator via HNET. On NCC
WAN, the HUB-4 communicates on each of four ports with either the MMX (XL3
Modem), the CMI-300 (MXL modem), NIM-1 FSI (MXL FSI modem), NIM-1W (MXL
RS-485), RPM (XLS RS-485), HUB-4 (XLS RS-485), HUB-4 (XLS modem) or up to 16
WAIO (Wide Area Input Output) boards. On the PMI-2 Concentrator, the HUB-4
communicates on each of the four ports with either the NIM-1W/NIM-1M (MXL
Modem), NIM-1W (MXL RS-485), RPM (XLS RS-485), HUB-4 (XLS RS-485), or HUB-4
(XLS modem).
Using the Modem Block module, communication distance is 8 miles (CMI-300/MMX-1)
or 10 miles (HUB-4 to HUB-4) over 18 gauge twisted pair lines depending on the quality
of the communication wires (attenuation cannot exceed -23 dBm [CMI-300/MMX-1] or
