Installation & Configuration Procedures
2.1 General Description
This section describes the procedures for installing and configuring the
SPA-V2 Public Address System. It is recommended that this section be
read together with delivered project documentation before installing the
system. The SPA system is designed for rugged use. However, as with
any other electronic equipment, reasonable care and judgment must
be exercised when handling this equipment. Hard shocks and rough
handling may damage electronic components.
L
Note that this manual describes the standard SPA-V2 system and equipment. For
systems with additional equipment and configuration, see project documentation
and relevant manuals.
2.2
Receiving and Inspecting the Equipment
Before unpacking the SPA system delivery, check the packing carton
for signs of damage. Any damage to the carton should be reported to
the supplier before proceeding further. When delivery is Ex Works, the
transporter is liable for damages incurred.
Open the carton, carefully remove the contents and check for any signs
of mechanical damage.
The SPA delivery package can, depending on the order, contain the
following equipment (see attached packing list):
● Rack containing amplifiers, modules, etc.
●
Microphone control panels and alarm control panels
●
Technical and User manuals
●
Microphones
● Speakers of different types
2.3
Planning the Installation
The design of the SPA rack depends on the functions that the system
requires, i.e. whether it shall be a PA (Public Address) or a combined
PA/GA (Public Address and General Alarm) system. (See section 2.)
To be able to plan the loudspeaker installation, you need the GA plan for
the vessel. The number of loudspeakers required depends on whether
the system is a PA or PA/GA system. GA for passenger vessels must
have two systems, each in a different fire zone.
