Installation Instructions
Model MMB-3
Main Control Board
OPERATION
The Model MMB-3 board from Siemens Industry,
Inc., in each MXL System controls operations
and monitors input device identity, network
communication, and operator commands that are
entered through the MKB Annunciator/ Key-
board. The MMB-3 also provides two analog loop
driver circuits. Each ALD-2I loop can be used as
Class B or Class A and can monitor and control
up to 60 intelligent devices as well as program-
mable device relays. The MMB-3 module can be
programmed and upgraded in the field. It is
equipped with two programmable Class B (Style
Y) or Class A (Style Z) notification appliance
circuits. Each circuit can activate up to 1.5 amps
of audible or visual notification appliances. The
MMB-3 has a user-defined Style 4 or Style 7
MNET communication port.
The module also has auxiliary relays for the
external monitoring of Common System Alarm,
Common System Trouble, and Common Supervi-
sory conditions. The Common Supervisory relay
is user programmable.
The MMB-3 includes a built-in battery charger
and transfer circuit. The charger is microproces-
sor controlled and incorporates a brownout circuit
that switches the System to standby batteries
during the loss or reduction of the primary source
AC.
The System can display the real time battery
voltage, the AC voltage, and the charger current
on the MKB display. It also has a 1 amp, 24 VDC
output that powers CZM-1/-1B6 modules.

Installing the MMB-3 Board
Unpack the MMB-3. Inspect the module, looking
for such things as integrated circuits (ICs) not
firmly seated in their sockets, bent IC pins,
connectors not properly installed, dirt, packing
material on the board, etc.
