1.3 STRUCTURE AND OPERATION OF THE SYSTEM
1.3.1 General description
The base configuration of the System functions as an Intercom command system
and enables to transmit voice communication via PA lines. The alarm generator initiates
an alarm, and the source of entertainment broadcasting plays back radio signals.
The System consists of the mounting rack 19IR or metal cabinet WME with a set of
modules for the proper functionality and connected units (microphone panels,
loudspeakers, etc.), general alarm units (alarm panels and signaling units) and other peripheral
devices.
SC of the following systems manufactured by NPK MSA LLC may be added to
the System: digital talk-back system ICB-131, marine automatic telephone system
ITS-1004,sound reception system NS-201 if it includes an alarm generator with VDR and
fire alarm system.
Figure 1 describes an example of the System composition.

1.3.2 The System’s functionality
The System’s functionality:
to transmit communication via PA lines, selective or pre-defined, at
max. distance of 700 m without quality loss;
to sound general and other types of alarm signaling (including manual and fire
alarm) via PA lines and signaling units; the alarms are initiated by an integrated alarm
generator or external general alarm system;
to broadcast entertainment programs via pre-selected PA lines from one or
several integrated entertainment sources on local loudspeakers or headphones; volume
may be controlled manually on the local loudspeaker or headphone; entertainment source
may be selected by a local selector;
to output signals to external systems (VDR, Integrated Marine Automation
Systems or external PBX);
to operate with two independent general alarm systems, split amplifiers or
broadcasting units;
the system may be controlled from a local or remote microphone panel
independently of the controls status on other microphone panels (if microphone panels
have the same priorities);
voice communication, alarm signaling and external signals from external ship
systems will interrupt entertainment broadcasting,
to control audio quality of transmitted voice communication on each PA lines;
to control sound pressure of sound signaling units; signal tones –at option;
volume control override of loudspeakers (set to min. or Off position) and
program selectors by alarm signal;
to control operation of PA lines (to detect short circuit or rupture);
to provide visual indication of the power status and connection of a subscriber
unit to PA lines;
to switch automatically to standby power in the event of the main power failure
or loss.
1.3.3 Priorities
The System supports the following priorities during operation with external
systems, see table 2.

1.6 MARKING AND SEALING
The System has a nameplate that identifies: the name and serial number, the
Manufacturer, date of manufacturing. The nameplate is attached to the rack enclosure.
The SCs have nameplates identifying the following:
the name and code of the SC;
serial number;
name and address of the Manufacturer;
date of manufacturing;
rated power consumption or net power;
rated current;
rated supply voltage or voltage range;
code of current type if rated frequency is not specified;
IP rating;
weight;
a disposal type;
information on conformity assessment.
The nameplates are attached to the SC casings. The SCs are not sealed.
Note –If a SC is small, information on the nameplate may be reduced and identify
only the name of SC and its serial number. More information is given in the technical
description.
1.7 PACKAGING
The SCs except the mounting rack 19IR are packed in corrugated board boxes,
ensuring their transportation and storage at the warehouse. The mounting rack 19IR is
attached to the tray and wrapped around with stretch film and cardboard, or without
cardboard.
Transport packaging is also used as returnable packaging for transportation of the
SCs to the repair location and back.
The transport packaging is not sealed.
