MIL-S-16032M

Abstract

This specification covers pressure, temperature, thermostatic, door, water, liquid level, liquid flow, and airflow switches, and single-purpose (smoke or combustion gas) detectors and flame detectors used on Naval ships for visual and audible alarm systems (that is, systems utilizing indicator lights, sirens, bells, alarm panels) in conjunction with steam or air systems, diesel engines, turbines, auxiliary machinery. This specification is not intended to cover thermostatic or pressure operated switches used as operating controls, unless interconnected with an alarm system or specifically required by other primary equipment specifications. <br>Types of switches and detectors shall be designated in the forms, as specified (see <a>3.2.1</a> through <a>3.2.1.5</a> and <a>6.2.1</a>). (See <a>figures 1</a>, <a>2</a>, and <a>3</a> for schematic representation of type designation.) <b><u>Intended Use:</u></b> Switches covered by this specification and their intended use are shown in <a href="#JEFKDAAAAAAAAAAA-X219">tables XIX</a> through <a href="#JEFKDAAAAAAAAAAA-X225">XXV </a>and <a>6.1.1</a>. <a id="JEFKDAAAAAAAAAAA-X219" name="JEFKDAAAAAAAAAAA-X219">TABLE XIX.
