1INTRODUCTION
This manual contains information regarding
MXL equipment and detectors that are US
Coast Guard approved. The use of any other
equipment in systems required by US Coast
Guard regulations, but not US Coast Guard
approved, should only be considered when
absolutely necessary. Special US Coast
Guard one-time approval would be required.
NOTE: When designing Fire Control
Systems for various types of vessels, the
designer should be aware of the required
vessel type, domestic and SOLAS regula-
tions applicable for that vessel.
The MXL Control Panel from Siemens
Building Technologies, Inc. is an advanced
fire protection and alarm control panel that
provides superior fire protection and multi-
plexed alarm reporting. Its use of unique
multi-processor network design along with
its ability to utilize both analog and conven-
tional detection devices, make it the out-
standing control unit in the life safety field.
Regardless of the size or complexity of the
life safety and security system require-
ments, the MXL system can be used for the
smallest to the largest applications.
The MXL is ideally suited for Marine, institu-
tional and industrial fire and security appli-
cations.
The MXL Control Panel can process logical
decisions based on the status of initiating
devices. The system will also respond to
specified sequences of output circuit operation.
The MXL Control Panel is capable of read-
ing and displaying the sensitivity of remote
intelligent/analog ionization and photoelecric
detection devices at the control panel.
The system complies with the requirements
of NFPA 72 and NFPA13. It is Underwriters
Laboratory 864 and 1076 security listed.
The basic MXL Control Panel can monitor
up to 2 analog loops, each containing up to
60 intelligent devices. Through the addition
of a MOM-4 card cage, the System can be
expanded to as many as 6 analog loops.
(With the addition of PSR-1 power supplies,
the System can be expanded to as many as
34 analog loops.)
The MXL Control Panel can control a wide
variety of System outputs, such as conven-
tional Form C relay contacts, solid state
outputs, supervised outputs to control alarm
notification appliances, municipal tie out-
puts, and leased line outputs.
The MXL Control Panel can process logical
decisions based on the status of initiating
devices. The System can respond with
customer-specified sequences of output
circuit operation.
The System continuously checks all soft-
ware and hardware for proper operation. It
continuously checks all System memory
components, control panel electronic hard-
ware, and the System program. A hardwire
watchdog circuit is provided to ensure that
System programs are functioning properly. If
I. Description of the MXL
Marine Control Panel
2a problem develops with the program or
processor, the watchdog circuit places the
System into a trouble condition and resets it.
To ensure reliable operation, the MXL
System is composed of independent mod-
ules, each with its own microprocessor. If
the main panels central processing unit
stops, these modules, operating in degrade,
still annunciate any alarm or trouble through
common lines called Any Alarm and Any
Trouble. All of the modules communicate
with the MXL Panel through a serial com-
munications system.
All modules are continuously supervised for
their presence and for proper operation.
Problems are shown on the display to aid in
servicing and troubleshooting.
The MXL System is designed so that fire
alarm operation has first priority over all
other modes of operation. If the System
loses battery and commercial power, it
automatically goes through an initialization
routine when power is returned.
EQUIPMENT LOCATION
MXL System equipment shall not be installed
in locations that require an exceptional
degree of protection such as those that are
exposed to weather, seas, splashing,
pressure-directed liquids or similar moisture
conditions. These locations include:
1. On deck
2. A machinery space
3. A cargo space
4. A location within a galley or pantry area,
laundry or water closet which contains a
shower or bath; and
5. Other spaces with similar environmental
conditions.
SOFTWARE
The MXL software was written in a high
level language for ease of maintenance.
The software incorporates a multitasking
operating system that allows the micropro-
cessor to handle many tasks almost simulta-
neously. This enables the MXL System to
handle communications to all initiating and
output option boards and to the annunciator.
This also enables the MXL System to check
that everything is running.
When the MXL Control Panel receives
power, the System runs a start-up proce-
dure that sets up all initial conditions. The
System then starts the operating system
and the initialization routines for all of the
tasks, most of which concern handling
System modules. When the display task is
finished initializing, it displays the default
time and date at powerup. Initialization of
other modules may take several seconds,
but this takes place in the background and
so does not affect System operation.
The MXL System polls all network addresses
to see that all specified modules are present
and that there are no unspecified modules.
Any modules or devices that do not agree with
the programmed data are reported as
troubles on the annunciator.

PSR-1 Remote Power Supply
Figure 15
NET-4 Board
Description of the MXL Control Panel
PSR-1 Remote Power Supply
The PSR-1 module is a microprocessor
controlled remote power supply and battery
charger. This module allows the basic MXL
System to expand to more than 2000 points.
It operates with an MPS-6 or an MPS-12 to
provide 6 or 12 amps of power for various
MXL modules.
The PSR-1 module:
1. Acts as an interface between remote
option modules and the MXL when used
with a NET-4 or NET-7 plug-in
communication module.
2. Can be used to power an MOI/MOD
annunciator driver set.
3. Can be used as an auxiliary power supply
in a stand-alone mode without an MXL.
There are nine status indicators on the PSR-1
(Refer to Figure 14). There are also two
relays used for common alarm and common
trouble or, if programmed, for local alarm and
local trouble.
NET-4 Communication Interface
The NET-4 provides the communication
interface between remote PSR-1 panels and
the main MXL. Each NET-4 connected
represents one network drop on the MXL
System. You can have up to 32 network
drops, including the MMB-2.
The NET-4 installs into the PSR-1 module
which provides all necessary power to the
NET-4. There are no configuration switches or
jumpers on the NET-4. (See Figure 15.)
11
NET-7 Communication Interface
The NET-7 module provides a Style 7
communication interface between the main
MXL and multiple remote panels in an MXL
System. Each NET-7, except the NET-7
connected to the MMB, electrically isolates
the pairs from the local power supply and
isolates ground faults to a single remote
panel. The MMB provides ground fault
detection for the two pairs.
Each NET-7 connected represents one
network drop on the MXL System. There
can be a maximum of 32 drops including the
MMB. The NET-7 has a network address
which must be set on the module and
installed into the CSG-M network map.
The NET-7 offers advanced performance
over the NET-4. NET-7s and NET-4s
cannot be combined in the same system.
MOI-7 Voice and Annunciator Driver
The MOI-7 is an MXL network module that
connects to a graphic annunciator using
MOD-16s and MID-16s. The MOI-7 can be
connected to either Style 4 or Style 7 wiring.
MOD-16 Output Driver
The MOD-16 Output Driver module is a
graphic annunciator driver controlled by the
MOI-7 module. Up to eight MOD-16s can be
used with an MOI-7. Each MOD-16 can
activate up to 16 outputs for a total of 128
outputs.
MID-16 Input Driver
The MID-16 Input Driver provides 16 gen-
eral purpose inputs for user-defined opera-
tions for the MXL. The MID-16 is controlled
by the MOI-7 module. Up to eight MID-16s
can be used with an MOI-7. The function of
each individual input is defined by the usage
assigned to it in the CSG-M.

PIM-1 Peripheral Interface Module
The PIM-1 module is an interface for an
MXL System to remote peripheral devices
such as printers, VDTs and CRTs. It con-
nects an RS-232C device or CRT to an MXL
System without the peripheral device's
protective ground causing a ground fault.
The interface operates at up to 9600 baud
without losing any characters.
CZM-1B6 Remote Conventional Zone
Module
The CZM-1B6 is an MXL intelligent device
that connects a single zone of conventional
devices to an analog loop. The CZM-1B6 can
power up to 15 compatible two-wire, ioniza-
tion or photoelectric smoke detectors. It can
also monitor an unlimited number of shorting
devices such as waterflow switches, thermal
detectors, manual stations, etc.
Each CZM-1B6 can be assigned a
32-character custom alphanumeric message.
It also includes an alarm indicator LED
which is visible through the cover plate.
The CZM-1B6 supports Style D (Class A)
and Style B (Class B) wiring. The module
uses one address on the analog circuit.
LIM-1 Loop Isolator Module
The LIM-1 Loop Isolator Module isolates
short circuits on MXL analog loops. By
placing devices between LIM-1s during
installation, a short in the wiring within that
group is disconnected from the rest of the
loop. The remainder of the devices continue
to operate. The LIM-1 operates in both Style
6 (Class A) and Style 4 (Class B) circuits.

It is a US Coast Guard requirement that the
fire detection system have two sources of
power. Most large ships have both main
generators and emergency generators;
therefore, they can satisfy this requirement
by arranging to have power supplied to the
fire detection system by both the main and
emergency generators.
In cases where there are no emergency
generators, battery backup power to the
system is required. Revised US Coast
Guard regulations have reduced the
required battery operation time to 36 hours
for passenger ships and 18 hours for all
II. Power Requirements
other types of vessels. In cases where it is a
desired option to furnish the fire detection
system with standby battery power, even
when there are main and emergency
generators supplying the system, there is
no specific battery operation time period,
although it would be recommended to be a
minimum of 18 hours.
When the smoke detection system is
furnished with battery backup power, it is
necessary to calculate the system power
requirement to determine the battery am-
pere-hour capacity necessary.
NOTE: An approved Power Transfer Relay must be used for the automatic transfer from
main power to secondary power when the main power source has 15% to 20%
potential variation. The transfer to secondary power creates a visual and audible
trouble signal on the MXL Control Panel. The Model PTR-1 Power Transfer Relay
from Siemens Building Technologies, Inc. was designed for this purpose.
Refer to the MXL Operation, Installation, and Maintenance Manual, P/N 315-092036, for

III. Audible Alarms
ALARM LOCATIONS AND REQUIREMENTS
Ten inch bells are required to sound in the following locations when any alarm initiating device is
actuated.
1. Alarm bell must always sound on the bridge regardless of which zone is in alarm.
2. Alarm bells must sound in the engine room, machinery spaces, and the control room when
the alarm is initiated in any of these spaces. In case the control room might be unattended
at the time of alarm, bells must also be installed in the passageways and lounge areas of
the licensed engineers quarters.
3. If an alarm is not acknowledged (silenced or reset) at the control panel within 2 minutes, the
control panel must automatically cause the General Alarm to sound.
NOTE: If it should be necessary to supplement the 10 inch bell audible output in high
noise background areas with horns, sirens, strobes, flashing or rotating lights,
the wiring to such supplementary alarm devices does not have to be supervised.
However, audible alarms other than bells must always be accompanied by lights
or strobes.
Refer to the MXL Operation, Installation, and Maintenance Manual, P/N 315-092036, for
solutions to design questions regarding specific MXL fire alarm control functions and modules.

V. Remote Annunciation
REMOTE ANNUNCIATORS
When the main control panel is located on the navigating bridge, remote annunciation is not
required by the US Coast Guard. However when the main control panel is located in a fire
control station which is not a constantly attended space, a supervised complete system status
annunciator is required.
IV. Initiating DevicesManual
Intelligent/Analog Manual Station MSI-10B/20B
Conventional Manual Station MS-51/501
Reference US Coast Guard Approved Equipment List
Manual stations are recommended for use with automatic fire detectors. If a fire is observed
before automatic detector response, the manual activation of the station results in the same
system response as automatic detection. Manual stations should be installed throughout the
accommodation spaces, the service spaces, and the control stations.
NOTE: One manual station should be located at each exit. The stations should be readily
accessible in the corridors of each deck so that no part of the corridor is more
than 60 feet (20 meters) from another manual station.
Refer to the MXL Operation, Installation, and Maintenance Manual, P/N 315-092036, for
solutions to design questions regarding specific MXL fire alarm control functions and modules.

VI. Detector Application and Spacing
2. THERMAL DETECTORS
2.1 Description and Function
All thermal detectors respond only to exces-
sive heat, which is assumed to be gener-
ated from a flaming fire. The detectors are
designed with different operating principles
as described below.
2.1.1 Fixed Temperature
The air temperature has to exceed the set
ratings of the devices in order to activate it.
The settings are 135 F, 190 F and higher
(on special order).
2.1.2 Rate Compensated
This type of thermal detector is similar to
the fixed temperature detector in operation,
but is compensated to eliminate the expected
thermal lag and, therefore, responds faster.
2.2 Spacing
Maximum approved spacing of thermal
detectors is as follows:
Maximum
Area Protected Distance from
Type (Square Feet) Sidewalls (Feet)
Fixed Temperature (DT-11) 625 (25 X 25) 12.5
Fixed and
Rate of Rise 2500 (50 X 50) 25

1. SMOKE DETECTORS
1.1 Description and Function
Smoke detector is the generic name given
to either ionization type or photoelectric type
detectors. The ionization type responds to
both visible and invisible products of com-
bustion, while the photoelectric type depends
on sensing visible smoke.
1.2 SpacingFor average areas with smooth ceilings and
normal air movement, the maximum recom-
mended spacing is 900 square feet or no
more than 30 feet between centers and 15
feet from a sidewall. In areas with higher air
movement, the detector spacing should be
reduced accordingly.
1.3 Application Limitations
1.3.1 On ceiling heights below 8 feet, the
possibility of unintentional alarms from
tobacco smoke does exist, especially in
areas where people might congregate. It is
recommended that smoke detectors in such
areas have their zones wired through alarm
confirmation module.
1.3.2 Smoke detectors should not be used
in areas where they could be subjected to
steam or moisture condensation such as in
galleys, laundries, etc. Thermal detectors
should be used in such areas.
22
3. PLANNING A FIRE DETECTION
SYSTEM
When planning a fire detection system,
make a choice of detector based on the
kinds of fires expected. The type and
quantity of fuel, possible ignition sources,
ranges of ambient conditions, and the value
of the property to be protected should all be
considered.
In general, heat detectors have the lowest
cost and false alarm rate, but are the slow-
est to respond. Since the heat generated by
small fires tends to dissipate fairly rapidly,
heat detectors are best used to protect
confined spaces, or directly over hazards
where flaming fires can be expected. They
are usually installed on a grid pattern at
their recommended spacing distances or at
reduced spacing for faster response. The
operating temperature of a heat detector
should be at least 25 F above the maxi-
mum expected ambient temperature in the
area protected.
Detector Application and Spacing
Smoke detectors cost more than heat
detectors, but respond faster to fires. They
are better suited to protect large open
spaces than heat detectors because smoke
does not dissipate as rapidly as heat does
in the same size space. Smoke detectors
are either installed according to prevailing
air current conditions or on a grid layout.
Photoelectric smoke detectors are best
used in places where wire insulation or
other smoldering fires may be expected.
Ionization smoke detectors are useful where
fire would be expected to develop into a
small flaming condition soon after pyrolysis.
NFPA Standard 72 Chapter 5 has more
specific information on the installation of the
various types of detectors.
23
3.1 Detector Application
In view of the problems that can be expected with the misapplication and location of detection
devices aboard ship, the guidelines below should be followed when designing systems.
These tables list situations where the use of smoke detectors, ionization and photoelectric
should be avoided.

stabilization equipment, ventilation and
air conditioning equipment, and similar
areas, including the shafts running to
them.
Monitoring Machinery Spaces
Because of the irregular shape of most
machinery spaces and the strong air
currents present, the number and type
of detectors used cannot be based on
the area protected, as is in the common
practice on land-based installations and
ship accommodation spaces. The best
design approach is to pick out all poten-
tial fire outbreak areas and place a fire
detector above each of them at deck
level. Areas of potential fire risk include
the following:
Auxiliary boiler front
Main boiler front
Fuel oil pressure pumps
Auxiliary generator sets
Main diesel engine fuel oil pumps
and injectors
Fuel oil purifiers
Lubricating oil purifiers
Fuel oil transfer pumps
Workshops
Electrical switchboards
Storerooms
Locate additional detectors with fairly
wide spacing to give general cover to
areas not containing special risk.
Detector Application and Spacing
25
Detector Application and Spacing
4. DETECTOR INSTALLATION
After the most suitable detector for the job is
selected, the location of the detector within
the space to be protected should be consid-
ered.
Spot type detectors are usually located on
the ceiling or side wall with the edge of the
detector located no closer than 4 inches
from the wall or ceiling. When heat detec-
tors are installed at their listed spacing,
detection times are approximately equiva-
lent to the operating time of standard 165F
link-and-lever sprinklers. If faster response
is desired, reduce detector spacing. Also,
where ceiling heights exceed 16 feet, or
where ceiling construction is not smooth,
reduce spacings accordingly. Specific
information on the treatment of joisted,
beamed, and sloped ceilings can be found
in Chapter 5 of NFPA (2002 Edition).
When installing any type of heat detector,
consideration should be given to sources of
heat within the protected space which might
cause false alarms. For example, locate heat
detectors away from unit heaters and ovens
where surges of hot air might be expected.
The installation of smoke detectors is more
critical than for heat detectors because
smoke transport is strongly influenced by
the convective air flow patterns within the
protected area. For this reason, smoke
detectors are not assigned a listed spacing
by the testing laboratories other than a
maximum area coverage of 900 square feet
per detector. Although a grid pattern can be
used as a starting point, care must be taken
to appropriately locate the heating supply
registers and return air registers. Smoke
detectors should be located away from
turbulence caused by hot air outlets. The
location of the smoke detectors should favor
return air because the return air draws
smoke toward the detector and because air
velocity at the return tends to be lower.
Smoke stratification also should be consid-
ered when smoke detectors are installed.
Smoke may stratify below a ceiling due to
temperature gradients or air flow along the
ceiling. When stratification is a possibility,
smoke detectors can be installed with
alternate detectors at different levels.
The installation of ionization type detectors
is similar to that of smoke detectors since
fire gases tend to flow with smoke and are
similarly affected by convected flows within
the protected space. They also must be
located away from sources of oxidizable
gases or vapors; for example, away from
substances like aerosol sprays or hydrocar-
bon solvents, as these substances could
cause false alarms.
Refer to the MXL Operation, Installation, and Maintenance Manual, P/N 315-092036, for
solutions to design questions regarding specific MXL fire alarm control functions and modules.

ALD-2I LOOP CONFIGURATION GUIDE
The ALD-2I loading graph on page 33 plots the ALD-2I Loop output current verses the total line
resistance. The results are used to determine the maximum line resistance, which can be
tolerated in conjunction with the number and types of devices connected to the loop. The current
for each device is listed on the graph. Note: This is device inrush current and must be used for
this calculation.
1. Add the individual currents for each device that is to be connected to the loop.
2. Locate the total ALD-2I current on the Y-axis and draw a horizontal line until it intersects
the curve.
3. At the point of intersection draw a vertical line down until it intersects with the X-axis. It is at
this point that the graph will yield the total amount of line resistance that can be tolerated by
the loop.
The ALD-2I loading graph is to used to maximize the number of devices that can be installed on
the ALD-2I loop of an MXL system.
The vertical axis of the graph is milliamperes of current and the horizontal axis is ohms. When
you know either the total device current on an ALD-2I loop or the total resistance (both wires) of
that loop, the graph can be used to determine the other variable.
EXAMPLE #1: The total line resistance of a loop is sixty (60) ohms. By using the graph you
will find that the total allowable device current is seventy-six (76) milliamperes.
EXAMPLE #2: The total device current on a loop is going to be eighty (80) milliamperes. By
using the graph you find that the maximum allowable loop resistance is fifty-
five (55) ohms.
