SECTION 1 - CHARACTERISTICS

1.1

GENERAL

This section describes operating instructions and operational characteristics of the SM-2 Automatic
Crew-overboard light. The information presented herewith is in conformance with U.S. Coast Guard
Specification 46 CFR 161.010 and 161.110.
The SM-2 is a lightweight, compact, battery operated, portable unit which uses modular
construction for basic circuits to simplify maintenance and replacement procedures.
The SM-2 has been redesigned and strengthened to pass the tough UL 1196 testing and MSC.81(70)
1.2

PURPOSE

This unit, shown in Figure 1, is a portable, electronic, floating strobe light, which automatically
rights itself and begins flashing when dropped into water. The SM-2 Light is designed to be carried
aboard all vessels, as well as artificial islands and fixed structures which are located on the outer
continental shelf. It is to be used as part of the required survival equipment complement. The light is
used to mark a position in the water, particularly in a crew-overboard situation. It must be installed
and used in conjunction with other equipment as required by U.S. Coast Guard Regulations.
1.3

COMPONENT RATINGS

Circuit design and component selection is such that component ratings cannot be exceeded when the
unit is operated throughout the entire range of all environmental tests. The SM-2 uses circuit
components and construction techniques, which have been manufactured to the specifications and
requirements of various civilian and Governmental agencies.
1.4

OPERATION

Instructions for operation and maintenance of the SM-2 Light are given on the instruction plate.
(See Figure 2) This unit does not possess any exterior operating controls. Equipment design is such
that controls for use during normal operation would not be detrimental to the reliability of the Light.
The circuit is electronically activated by a gravity switch when the unit is inverted.
1.5

EFFECT OF TESTING

Equipment design is such that application of specified tests will provide no discernible condition
which would be detrimental to the reliability of equipment manufactured in accordance with such
design.
1.6

ENCAPSULATING MATERIALS

Materials used to encapsulate the Module are of the type that will not have any injurious effect on
the insulating materials to which they are applied and do not cause corrosion or deterioration of any
adjacent part. These compounds do not flow at temperatures below +85° C or crack at temperatures
down to -34° C.
