FIREPOWER MXL-IQ - Manual (Page 2)

The basic MXL-IQ control unit consists of the following
subassemblies: SMB-2 Main Control Board; MPS-6 Power
Supply; MKB-4 Annunciator and Keyboard; MSE-3L
Enclosure. Optional modules which can be installed with
the MXL-IQ System include: MPS-12 Power Supply;
MOM-2 or MOM-4 Expansion Card Cage; CRM-4 Control-
lable Relay Module; CZM-4 Conventional Zone Module;
CSM-4 Controllable Signal Module; PIM-1 Peripheral
Interface Module; CMI-300 CXL Modem Interface Module;
NIM-1R LifeLINK Network Interface Module; MOD-16
Output Driver; MOI-7 Network Interface; MID-16 Input
Module; MXL-VDT Interactive Video Display Terminal; MXL-
G Color Graphic; MXL-GT Color Terminal; a full range of
intelligent/analog detectors and devices (see table 1).
SMB-2 Main Control Board
The function control of the MXL-IQ is contained on the
SMB-2 Main Control Board. The on board 16 bit micro-
processor along with nonvolatile EPROM and Flash
memory allow the system to be custom configured to
meet a wide range of customer requirements. The SMB-2
controls operating sequences and monitors input device
identity, detector sensitivity, network communication and
operator commands entered through the MKB-4 Annuncia-
tor/Keyboard. The SMB-2 also 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 Siemens Fire Safety intelligent input
devices and 60 programmable device output relays.
The SMB-2 is equipped with 2 programmable and
codeable Style Y (Class B) or Style Z (Class A) notification
appliance circuits. Each circuit can activate up to 1.5 amps
of listed audible or visual notification appliances.
Auxiliary relays are provided for external monitoring for
Common System Alarm, and Common System Trouble.
The SMB-2 includes a built-in battery charger and transfer
circuit. The charger is microprocessor controlled and
incorporates a brown out circuit which switches the
system to optional standby batteries during loss or
reduction of the primary source AC. Upon command, the
system is capable of displaying the real time battery
voltage, AC voltage, charge current and other power data
on the MKB-4 Alphanumeric display. It also includes a 1
Amp, 24 VDC, output.
Control, Detector Sensitivity, Alarm Verification by Device
or Zone, 32 Character Custom Alphanumeric Messages
per device, System Operation Passwords and NAC
Coding. The SMB-2 provides a port for connection of the
programming laptop computer.
MKB-4 Annunciator/Keypad
The MKB-4 mounts on a hinged frame in the MSE-3L
enclosure and provides an 80 character backlit LCD
alphanumeric annunciator which continuously scrolls to
display information concerning system status along with
32 character user defined device messages. When
multiple events occur, the MKB-4 displays the last event
of the highest priority. Additional data can be viewed by
depressing 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 a wide variety of
specific menu driven operation, programming and mainte-
nance functions.
A set of 12 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-4 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-4 Annunciator communicates with the SMB-1
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-IQ Control Unit and its expansion modules with
power required for normal operation. The unit incorporates
a resettable circuit breaker on the primary input and
includes a built in AC line filter for surge and noise sup-
pression. The MPS-6 mounts in the MXL-IQ enclosure
backbox. (MSE-3L)
The SMB-2 is fully FIELD PROGRAMMABLE off line using
a laptop computer. Complete system configuration can be
easily uploaded, downloaded or edited using CSGM
custom programming software. Program options include
but are not limited to smoke detector environmental
compensation, Detector Pre-alarm, History Logging,
Output Control by Event; Check and Change Time Based
