Introduction - Siemens System 3 Manual

System 3 from Siemens Industry, Inc. was
developed as a flexible, wide range fire detection
and control system. System 3 uses a modular
concept: Only those functions desired in each
system are built into that system. Any number of
various input and output circuits may be custom-
assembled in various size enclosures.
This manual contains information regarding
only System 3 equipment and detectors that
are US Coast Guard approved under
Certificate No. 161.002/17/8. 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.

INTRODUCTION

Drawing No. 315-085585 (Coast Guard Sys-
tem 3 Specification) is considered a part of
this manual (See print in Appendix, page 30).
In addition, the typical internal module to
module wiring of two control panels is shown
on pages 2 and 3 in the form of typical Wire
Lists. Either a wiring list of this type or a
complete point to point wiring diagram should
be furnished with every system and should be
kept as on-board documentation for future
reference in system service and maintenance.
NOTE: When designing Fire Control Systems
for various types of vessels, the designer
should be aware of the required vessel type,
domestic and SOLAS regulations applicable
for that vessel.
