MIL-A-17196E

Abstract

This specification covers alarm switchboards, alarm panels, remote signal units, sentry alarm switch, and special alarm connection box for use with Naval surveillance and protective systems. <br>Alarm switchboards shall be of the following types, as specified (see <a>6.2.1</a>): </span><pre> <u>Type</u> <u>Line voltage, 60 hertz (Hz)</u> <u>Supervisory voltage</u><a><u>1</u>/</a> IC/SCG 115 Volts (V) 220 Volts direct current (V d.c.) IC/SFZ or S4FZ 115 V 120 V d.c. IC/SM 115 V 5 + V d.c.; root mean square (rms), &#8722; 0 full-wave, rectified (unfiltered)</pre> <br> <br>The size of the switchboard shall be designated by the full capacity of the enclosure (see <a>3.4.1.1</a> through <a>3.4.1.3</a> and <a>6.2.1</a>). A typical designation of the actual number of circuits required is as follows: <pre> Number of circuits Type Size required ---- ---- ------------------ IC/SM 20 18</pre> <br> <br>Alarm panels shall be of the following types, as specified (see <a>6.2.1</a>): <pre> Number of Supervisory Type lines Line voltage (60 Hz) voltage ---- --------- -------------------- ----------- IC/B51 2 115 V 120 V d.c.<a><u>1</u>/</a> IC/B52 4 115 V 120 V d.c.<a><u>1</u>/</a> IC/BCG51 2 115 V 220 V d.c.<a><u>2</u>/</a> IC/BCG52 4 115 V 220 V d.c.<a><u>2</u>/</a></pre> <br> <br><strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Ship Engineering Center, SEC 6124, Department of the Navy, Washington, DC 20362 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.</strong> <br>Remote signal units shall be of the following types, as specified (see <a>6.2.1</a>): <pre> IC/EA IC/EAP IC/EAW</pre> <br> <br>The sentry alarm switch shall be a type IC/SW. <br>The special alarm connection box shall be the type shown on Drawing SS-402-1701749. <br><b><u>Intended Use:</u></b> Types IC/SCG and IC/BCG switchboards are intended for use with combustion gas and smoke detectors, type IC/CG or IC/CGD. Types IC/SFZ and IC/S4FZ alarm switchboards are intended for use with security systems. The switchboard combines features of both the IC/S and IC/SM type of alarm switchboards; however, added features are employed to render the circuitry and mechanical components tamper resistant. Type IC/SM alarm switchboards are for uses not specifically requiring the IC/SCG, IC/BCG, IC/SFZ or IC/S4FZ (see <a>6.1.1.1</a> and <a>6.1.1.2</a>). Alarm panels are intended for use in alarm systems where only two or four lines are required. Where a larger number of lines is required, a type IC/SM or type IC/SCG alarm switchboard should be used. <br>
