1. Installation Guide
1.1 General
1.1.1 Planning: The installation should be planned in details before commencing. The cables should be
listed in a cable plan, with number of pairs etc. The location of each unit in the communication system
should be planned to obtain maximum performance and user availability.

1.1.2 Power: The operating power is 220VAC 60Hz as primary and same AC or 24VDC as backup. With
automatic switching between primary and secondary power source.

1.1.3 Marking: Each cable is to be marked with cable numbers. Each conductor is to be marked with the
specific termination numbers. Please note that MRC uses plug-able screw terminals in all units.

1.1.4 Fastening: Where applicable, the cables and the conductors shall be clamped to the structure with
cable ties.

1.1.5 Preservation: Prior to, during, and after installation the equipment must be handled with care. And
protected against acid holding fluids, pollution, moist, impacts etc. This is in order to avoid damaged
equipment, for which MRC will claim void warranty.

1.1.6 Cable Requirements: All cables used in the MPA system must be of approved ship cable type.
Requirements:
- Common outer screen
- Individually twisted pairs
- Recommended conductor size is minimum 0.75 mm²
- All cabling in the MPA must be a separate network.
- Do not combine different systems in the same cable. This is to prevent disturbance and noise caused
by interference.

1.1.7 Screen Connection

In order to obtain maximum
performance after installation, it is
necessary to terminate the cables and
ground the screens in a good manner.
The cables are to de-isolated by
removing approximately 500mm of the
outer insulation. Then the screen braid
is cut off approximately 30mm longer
than the outer isolation. The conductors
are to be de-isolated and ferruled
before they are inserted into the
terminals.
The outer screen is clamped to the
cable fixing rails inside the cabinet.
Cable ties of a conductive type (metal)
are recommended for best result.

Fig. 1 The cable outer screens are to be terminated as

shown. Conductive type of cable ties is recommended to
obtain best possible screen connections.

1 Operating Description
1.1 Paging Function
Paging is possible from the MPA-9000 PA control unit and the emergency microphones.
It is also possible to page from a PABX line, or other external PA sources.
Paging may be performed in any combination up to the eight zones. And the PTT-key must be
continuously pressed during messages.
General call is activated by keeping the GA switch pressed down for more than half a second.
The PTT and GA switch can be configured to cover a number of zones directly, desired selecting zones.
Default zone selection for PTT is “All zones without zone 1 for cabin room.
Default zone selection for General Alarm Call is “All zones”.
Emergency microphones automatically activate GA switch.

1.2 Attention Tone

When paging, a “ding-dong” attention tone will be distributed over the loudspeakers first. The duration of
this attention tone is approximately 2 seconds. Therefore, wait at least 2 seconds before starting
message

1.3 Priority
The MPA-9000 system has configurable user-priority. There will always be only one user in the system.
Alarms also have configurable priority, but will always have priority over PA-messages. Meaning that an
alarm will override all PA messages, and the user will lose access for a while. PA-user can regain access
by releasing the PTT-key, and then press it again.

1.4 Local Mute

Each MPA-9051 remote control unit has built-in mute relays, which will be active during paging from this
user. Routing local speakers through these relays will minimize the risk of audible feedback.

1.5 Volume Override

Each zone has a "volume override" output that will disable local volume settings.
In an entertainment system it is convenient to have local volume controls at the loudspeaker. However,
alarms and PA messages needs to be distributed at full volume.

1.6 Alarm Activation/Reset.

The alarms may be automatically activated and reset through the alarm interface.
Alternatively a General Alarm switch panel can be used to set/reset up to two different alarms.
An active alarm is indicated on the MPA-9000 operation unit by a green alarm-led. The MPA system can
generate most standard alarm-tones.

1.7 Alarm Priority.

All alarms can be configured with different zones and priority, as shown in the list below. An alarm
always has priority over PA-messages. Thus will an active alarm break down any PA message or
entertainment. The PA user may regain access by releasing the talk key, and then press it once more.
However, an alarm cannot be overridden for a while.

＊CAUTION＊
1) PA emergency broadcasting is possible while GA is in use.
2) Pressing the button of the microphone with W/H authority while operating GA causes PA to shift
automatically to Emergency mode regardless of the speaker selector (in this case, PA will be protected
from unauthorized access).

(QAS-ADD-008/0/09.09.25) manual\pabx\MPA-9000\MPA-9000_eng.doc ( MRC MARINE RADIO CO., LTD.)

 MARINE RADIO CO.,LTD. Subject : PAGA System Page : (40 / 47)
주/선박무선 Date : 2010.12.09 Doc. : MPA-9000_Eng(Rev. 1.0)

3) Operating GA by pressing the GA switch during regular PA broadcast from W/H causes regular
broadcast to continue. In this case, releasing and pressing the relevant microphone again cause PA to
shift automatically to emergency mode.
4) Once an GA STOP signal is issued, GA stops even if it is in use. A PA STOP signal is also supplied.
5) A PA STOP signal is delivered from GA to PA and an GA STOP signal from PA to GA.
6) The contact point capacity of the Dry Contact should be at least 1A or higher.

② GA bell, buzzer, PA speaker, or other equipment (7 short and 1 long tones)
③ PA stop signal: GA delivering the contact point signal to PA
④ On/off button for the W/H microphone
⑤ GA stop signal: Contact point signal sent from PA to GA
⑥ PA system speaker

1.8 Broadcasting Priority

This system is operated in the following order:
1. 1st : Emergency broadcasting from the wheelhouse - highest priority among emergency, fire, and
other alarms
2. 2nd : General(Abandon/Muster) alarm
3. 3rd : Fire(HC/H2S) and other alarm
4. 4th : Automatic Call : Paging by "0"
5. 5th : Regular broadcasting from the PA main control unit
6. 6th : Broadcasting from the radio, cassette, CD, etc. on the GA

1.9 Talk-Back (Max: Seven (7) positions) - Talk-Back Area

: Wing PORT/STBD
: Upper Deck FORE/AFT
: Steering Gear Room
: ECR (Engine Control Room)
: CCR (Cargo Control Room)

1.10 Entertainment
The MPA-9000 system can have up to 4 entertainment sources. This can be radio SW/AM/FM or
CD-players, CD-shuttle, DVD, tape cassette players and an external source like TV or video signals
(options). These sources can be distributed to any of the 6 zones. Configuration is done through the
keypad on the MPA-9000 front-panel. Status in each zone is also indicated on the same keypad.

1. Commissioning Test and Troubleshooting

The longevity of the equipment depends on maintenance and management. Therefore, the system
should be inspected periodically in order to prevent unexpected damage. Before conducting inspection,
however, turn off the main power switch in order to prevent electric shock and short circuit.
(1) Cleaning: Remove the grease and dirt thoroughly using a soft cloth.
(2) Inspection of Components: Check the components for abnormalities such as the corrosion of wires,
soldering, and corrosion of the copper foil of the printed wire circuit board.
(3) Voltage Check: Check the voltage at the checkpoints of the circuit in order to detect any and all
abnormalities as early as possible.

1.1 Power Source

Status Cause of Defect Inspection and Repair
Power line breakage Check for power line breakage.
Poor contact Check the contacts of terminals.
Power defect Fuse breakage Check the fuse holder.
Rectifier defect Check the RECTIFIER I/O.
Rated voltage IC defect Check the 7812, 7805 I/O (rated voltage IC).

1.2 Speaker
Status Cause of Defect Inspection and Repair
Output transformer defect Check the transformer's 10Ω, 12Ω.
Check SP terminals 3, 1, and 2 of the terminal board
Speaker Poor contact

output defect
Speaker line defect Check for speaker line breakage or misplacement.
Speaker defect Check the transformer inside the speaker.

1) For regular broadcasting, a signal is sent through Output 1 and Output 3. Setting the analog tester to
resistance and connecting to Output 1 and Output 3 cause a "click" sound to be generated. In this case,
the volume can be controlled, and the broadcast, stopped by turning the switch off.
2) For Emergency broadcast, a signal is sent through Output 2 and Output 3, continuing even when the
switch is turned "Off." Setting the analog tester to resistance and connecting to the terminals cause a
"click" sound to be generated similar to Section 1.
