MOI-7
NET-4 Communication Module
The NET-4 is a plug-in type module used to provide
communication between the Cerberus Pyrotronics MXL
and various other MXL Remote Modules. It is designed to
plug into an edge connector type slot on the PSR-1
Network Supply. The NET-4 provides NFPA Style 4 type
communication. This communication is RS-485 operating
at 19.2K Baud. The communication is fully digital.
NET-4
NET-7 Style 7 Network Interface Card
The NET-7 is a microprocessor controlled MXL network
interface module which allows the wiring of the MXL RS-
485 network in an NFPA Style 7 configuration. The NET-7
plugs into a half slot of the MOM-2/4 card cage at the MXL
command center (MMB-1) and the PSR-1 or MOM-4 slot at
the MXL remote units (MXLR, MXLRV). The NET-7 provides
two independent and fully supervised communication
paths allowing system operation through an open as well
as short circuit. It also isolates the power supplies at each
remote unit providing the ability to localize ground fault
conditions. The communication operates at 19.2K Baud
and is digital.
PSR-1 Remote Power Supply
The PSR-1 is a microprocessor controlled remote power
supply and battery charger for use with the Cerberus
Pyrotronics MXL. It operates in conjunction with either an
MPS-6 or MPS-12 to provide 6 or 12 Amps of power for
use with various MXL modules. When used with a NET-4 or
NET-7 plug-in communication module, the PSR-1 becomes
a part of the MXL’s RS-485 Network. It acts as an interface
between remote option modules and the MXL.
PSR-1
PIM-1 Interface Module
The PIM-1 is an MXL option module which provides a
bidirectional isolated RS-232 port for connection to periph-
eral devices such as printers, CRT’s, VDT’s and Color
Graphics. The PIM-1 mounts in the MXL Enclosure. It
connects to the MMB-2 and provides a screw terminal
block for connection of RS-232. A number of supervised
and non-supervised formats are available.
MOI-7 Output/Input Module
The MOI-7 is an MXL RS-485 Network module which
provides a fully programmable serial interface to the MOD-
16 output drivers, MID-16 input drivers. When used with
the MOD-16’s, it provides a serial annunciator or relay
driver. When used with MID-16, it provides programmable
inputs.
Each MOI-7 can operate up to eight MOD-16’s and eight
MID-16’s simultaneously. Each MOD-16 output and MID-
16 input is independently programmable via the MXL
custom software.
PIM-1
MOD-16 Output Driver
The MOD-16 is an output driver module used in conjunc-
tion with the MOI-7 as a part of the Cerberus Pyrotronics
MXL System. Up to eight (8) MOD-16s can be connected
to an MOI-7 interface module. Each MOD-16 provides 16
