MMB-2 Main Control Board
The function control of the MXL is contained on the MMB-2
Main Control Board. The MMB-2 controls, operates and
monitors input device identity, network communications as
well as operator commands that are entered through the
MKB annunicator/keyboard. All operations are supported
by either the MPS-6 or the MPS-12 power supply, eliminat-
ing the need for external power supplies. The MMB-2 is a
direct replacement of the MMB-1 therefore providing total
backward compatibility.
The MMB-2 provides 2 ALD (Analog Loop Driver) circuits.
Each ALD loop can be configured as Style 4 (Class B) or
Style 6 (Class A) and can monitor and control up to 60
Cerberus Pyrotronics analog input devices and 60 pro-
grammable device relays. The MMB-2 is equipped with 2
programmable and codable Style Y (Class B) or Style Z
(Class A) notification appliance circuits. Each circuit can
activate up to 1.5 amps of Cerberus Pyrotronics audible
and visual notification appliances.
The MMB-2 includes a built-in battery charger and transfer
circuit. The charger is microprocessor controlled and
incorporates a brownout circuit that switches the system to
standby batteries during the loss and reduction of the
primary source AC. Upon command, the system is ca-
pable of displaying the real time, battery voltage, AC
voltage and the charge current and other power data on the
MKB alphanumeric display. It also has a 1 amp, 24 VDC
output that powers the CZM-1 modules.
The MMB-2 is designed with a built-in mounting bracket.
The MMB-2 mounts directly to the MBR-MP mounting plate
for mounting in either the MME-3 or MME-6 backbox
enclosure. The MMB-2 can also be mounted in the MBR-2
or MBR-1 enclosures. MBR-1 requires additional mounting
brackets.
The on-board 16 bit microprocessor along with nonvolatile
EPROM and Flash memory allow the system to be custom
configured to meet a wide range of customer requirements.
The MMB-2 provides a port for connection to a laptop
computer allowing for off-line field programming. Com-
plete system configuration can be easily uploaded, down-
loaded, edited and changes verified using AccuLINK™
custom programming software with integrated Compare™
system software. Program options include but are not
limited to EnviroLINK™, smoke detector environmental
compensation with two maintenance alert levels,
ChronoLINK™ history logging, output control by event,
check and change time based control, detector sensitivity,
alarm verification by device or zone, 32 character custom
alphanumeric messages, system operation passwords and
NAC coding.
MKB-2 Annunciator/Keypad
The MKB-2 mounts on a hinged frame in the MXL enclo-
sure and provides an 80 character backlit LCD alphanu-
meric annunciator which continuously scrolls to display
information concerning system status along with 32
character user defined device messages. When multiple
events occur, the MKB-2 displays the last event of the
highest priority. Additional data can be viewed by depress-
ing the NEXT key. At any time, the display scroll can be
stopped by depressing the HOLD button. Switches are
provided for acknowledging fire alarms, supervisories,
security conditions, and system troubles. An individual
switch is also provided for silencing the system notification
appliance circuits. A separate switch is used for resetting
the control panel.
A 10 digit numeric keypad is supplied to allow entry of the
user passwords, as well as perform specific menu driven
operation, programming and maintenance functions.
Another series of switches located on the MKB-2 allows
user access to the TSP-40 Thermal Strip Printer, when
used.
A set of user assignable “Function” keys provide single
button access to a variety of system commands. These
switches may be used to perform system operation such
as “Drill,” manual relay control, zone disconnect, etc.
Contained on the MKB-2 annunciator are system status
indicator LED’s which can function even if the main system
microprocessor fails. They provide indication of Main
Power On, Fire Alarm, Security Condition, System Trouble,
Supervisories, System Audibles Active/Silenced and Partial
System Disable.
The MKB-2 Annunciator communicates with the MMB-2
Main Control Board through the system network link.

MPS-6 Power Supply
The MPS-6 is a fully supervised power supply which
provides the system with primary DC power. It is rated at
6.5 Amps and is unfiltered and unregulated. It supplies the
MXL Control Unit and its expansion modules with power
