(5) Inventories of keys and locks will be conducted semiannually. This inventory will include the
backup or second set of keys. Inventory records will be kept in unit files for one year, then destroyed.
c. Intrusion Detection Systems (IDS).
(1) IDS alarms are essential parts of the physical security system. These devices, however, are
not a substitute for barrier protection and administrative control. The IDS shall be an approved DOD
standardized system. One example is the Joint-Service Interior Intrusion Detection System (J-SIIDS).
COs are responsible for ensuring that certain personnel have proper clearance. These are those
persons who must install, maintain, or repair the system.
(2) All structures or containers storing category II and above AA&E will be protected by an IDS.
This will hold true unless such structures or containers are continuously manned or under constant
(3) Plans and specifications for installation of commercial IDSs must be forwarded through
(4) IDSs are sometimes used at arms storage rooms in civil communities. If so, arrangements
will be made, if possible, to connect alarms to civil/campus police headquarters. From there immediate
response can be directed in case of unauthorized entry.
(5) A daily log will be kept of all alarms received. This will include the nature of the alarm.
Examples are intrusion, system failure, or false alarm. When appropriate, a copy of the log should be
forwarded to the supporting engineer office. There the log will receive evaluation, and necessary
maintenance will be ordered.
(6) Transmission lines for the alarm circuits must be electronically supervised. This will
preclude tampering. Lines must also be inspected often by guard personnel. A protected backup
power supply should be approved.
d. Security of tools and high value items.
(1) Tools located in the vicinity of arms storage areas will be secured in a locked container, and
they will be removed from the vicinity of that building or room. Sometimes an arms storage facility is
the only secure location available. If so, such tools will be stored there within a locked container. Other
times the access door to an arms room is located within the unit supply room. If so, tools will not be
stored in the supply room. Examples of such tools are hammers, bolt cutters, chisels, crowbars, and
similar items. These would aid in gaining forced entry.
(2) Other secure storage facilities are often reasonably available. If so, high value items other
than weapons and limited amounts of ammunition will not be stored in the arms room. Examples of
