Description
MOM-4 Card Cage
The MOM-4 Card Cage contains 4 slots for
optional module cards; it can handle 4 half-
width cards or 2 full-width cards. The MOM-4
provides 2 power-connector receptacles
and 2 data-connector receptacles. A 24 VDC
cable that provides the main power used by
the optional modules, and an 8-wire ribbon
cable for connection of 5 VDC and data, are
provided with the MOM-4 installation kit.
NIM-1W Network Interface Module
The NIM-1W provides a communication
path for the following uses:
• as an MXL-IQ networking interface
• as a connection to Foreign Systems
• as a connection to Air Sampling detectors
When used as a networking interface the
NIM-1W supports the connection of up to
63 MXL-IQ Systems. This network also
supports a Network Command Center
(NCC) that monitors all the MXL-IQs in the
networked group.
Output logic between MXL-IQ panels is made
using CSG-M programming. CSG-M versions
6.01 and higher include options for networked
MXL-IQ systems. Each MXL-IQ System is
assigned a panel number. This panel
number allows interactive programming
between panels using CSG-M.
The NIM-1W supports Style 4/7 connection.
In the event of an NIM-1W communication
failure, each MXL-IQ System continues to
operate as a stand-alone panel.
The NIM-1W can also be configured as an
RS-232 or RS-485 two-wire interface to
foreign systems. This operation is called
FSI (Foreign System Interface). The FSI
responds to a protocol and gathers infor-
mation about the MXL-IQ status. The
interface supports both single MXL-IQ
Systems and networked systems. Typical
use of this interface is between the MXL-IQ
and building management systems.
