The IDS is considered for security classification if it meets the specific classifying criteria in AR 380-5. If
classified, appropriate personnel security clearances must be obtained.
Only authorized personnel may be allowed access to unclassified IDS installation wiring diagrams for a specific
facility or location. This also applies to information on known, specific vulnerabilities or counter-measures
affecting the IDS.
According to AR 380-67, The Department of the Army Personnel Security Program, dated 9 September 1988,
civilian employees whose duties involve the design, operation, or maintenance of IDSs require the completion of
a favorable National Agency Check with written inquiries (NACI) before they may be appointed to such
A check of the National Crime Information Center (NCIC) for installers and maintainers of unclassified IDSs is a
command decision. This decision is based on the sensitivity of the area to be protected and the need for quality
control over personnel having access to the area and the IDS.
All installers, maintainers, and operators of unclassified IDSs must undergo a command-oriented security check.
This security check should be made with the area provost marshal or other agencies that might have information
on file that bears on the honesty or stability of the individual. The requirement for command-oriented security
checks should be based on local jurisdiction policies, the local threat and sensitivity, and the vulnerability of the
All keys required to be installed on IDS components must be safeguarded and controlled.
Periodic system operational checks must be made and logged by unit security personnel. A visual inspection of
the components and the conduits is made for evidence of tampering, and operational checks of sensors are made
to ensure that the sensors activate.
Installation physical security inspectors must include a check of each IDS during all security inspections to verify
that the IDSs are operating satisfactorily. These checks must include an inspection of the components and the
conduits for evidence of tampering. The unit's log entries and records regarding the operation and inspection of
each IDS must also be checked.
Before accepting a newly-installed IDS for operation, an inspection must be conducted by qualified technical
personnel to ensure that the system meets the minimum acceptable standards outlined in AR 190-11. The
statement of verification is maintained in the using unit's organizational files. DA Form 4604-R may be used to
record this verification inspection.
The maintenance of IDSs is provided only by qualified personnel. Such maintenance must be performed
consistent with operational requirements to ensure the continuous operation and reliability of each system in use.
The duress signaling system must be considered for arms storage facilities whenever constant surveillance posts
are used to protect category I and category II AA&E.
Signs prominently announcing the presence of an IDS must be displayed on ammunition storage rooms,
magazines, or perimeter barriers using such a system. These signs are affixed at eye level when possible. They
are affixed on the exterior walls containing an entrance to the ammunition or explosives storage room, vault,
building, or magazine. In the case of alarmed barrier fences, they are affixed on the outside of the fence at about
100-meter intervals. They must be placed where they will not hinder observation or fields of fire. Signs
