g. Guard supervisory system having key operated electric call boxes.
These should be located strategically throughout the post. By inserting the
key in a cell box, a guard can make a routine tour report or summon
emergency aid.
Tampering with the transmitting key or the call box
automatically locks the box.
This causes a failure of the signal and an
alert for immediate investigation.
18. Alternate Communication System.
Alternate communication systems are
always advisable for use in emergencies.
emergency conditions. Added to the normal flow of messages, the calls may
overload the existing system at the very time that sure and rapid
communication is vital.
The most efficient emergency reporting system
consists of direct connection to the guard or communications center from
telephones strategically placed throughout the post.
Use of these
telephones should be restricted to emergencies and guard reporting only.
Wires of alternate systems should be separated from other communication
lines, and they should be in underground conduits.
For emergency
communication with agencies off post, leased wires or a radio adjustable to
civil police and fire department frequencies should be available.
19. Joint Services Interior Intrusion Detection System (J-SIIDS). J-SIIDS
was designed for standardized use by the DOD.
The J-SIIDS has a high
detection capability with low nuisance alarms when properly installed and
proper phone lines are used. In this text, nuisance alarms are those whose
activation results from other than the actions of a perpetrator.
For
example, stray animals, wind, dust, tall grass, etc., may activate alarms.
a. Use of J-SIIDS. The system was mainly designed for use and security
of arms, ammunition, and explosives (AA&E) areas; however, it had been
certified for use in finance offices, PXs, aircraft hangars, and narcotics
storage areas.
All commercial systems used in lieu of J-SIIDS will be
tested and technically reviewed in accordance with AR 190-13 before purchase
and installation.
b. This system consists of a family of sensors that can be used singly
or in combination. It is to provide detection of intrusion. Sensors are
grouped into the following four categories:
(1) Penetration.
(2) Point.
(3) Motion.
(4) Duress.
c. Under current regulation, AA&E protected by an IDS will use at least
two types of sensors (i.e., penetration and motion).
