INTRODUCTION
The MPA 1600 system is a marine and offshore Public Address and General Alarm system. It meets
the requirements for PA/GA, and entertainment, distribution onboard ships and mobile offshore units.
The system conforms to SOLAS, IMO and IEC regulations. Based on modular design and flexible
configuration, it covers a wide range of installation complexities. Ranging from, small single loop
systems, to large duplicated systems.
1.1
PA CONFIGURATION, CARGO VESSELS
In MPA 1600 system onboard cargo vessels and where GA is not integrated into the PA system there,
is no requirement for a duplicated system. All loudspeaker loops however shall be arranged as closed
loops.
1.2
PA CONFIGURATION, PASSENGER VESSELS
In MPA 1600 system onboard passenger vessels, the requirement is a duplicated system in order to
minimize the effect of one single failure. The centralised duplicated equipment (operation unit and
amplifiers) must be separated and located in different fire zones. The loudspeaker loops from each
system is to be segregated throughout the ship.
All loudspeaker loops shall be arranged as closed loops.
1.3
PA/GA CONFIGURATION, ALL VESSELS
In MPA 1600 system onboard cargo vessels and where GA is integrated into the PA system as a
combined PA/GA system the requirement for duplication is the same as for Pa systems onboard
passenger vessels as described above. (Ch. 1.2)
1.4
TYPE NUMBER / SYSTEM IDENTIFICATION
In order to recognise and identify different version of an MPA1600 system there is an identification
system marked on all cabinets.

INSTALLATION GUIDE
2.1
PLANNING
The installation should be planned in details before commencing. Sound pressure levels and amount of
loudspeakers must be decided. 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.
2.1.1
General
The major requirement of a GA / PA system is sufficient coverage and sound pressure level (SPL) for
alarms and PA messages to be heard throughout the installation.
The minimum requirement during normal operating conditions for GA is 80dBA and at least 10dBA
above the ambient noise level in both interior and exterior spaces. In the cabins sleeping positions and
bathroom the minimum requirement is 75dBA and at least 10dBA above the ambient noise level.
