In addition to ON and OFF switches that are not located at a central control system, the ACCESS and SECURE
switches are located within the alarmed area. The IDS must be designed to cause an alarm to sound at the
annunciator panel when the system is turned off and when a malfunction occurs. An IDS installed to protect arms
rooms must consist of two types of sensors with different methods of activation (such as a balanced magnetic
switch on the door and ultrasonic motion sensors inside the arms room). When practical, the use of additional
levels of protection (such as duress signaling components) is encouraged.
Components of the DOD standardized system must be used as replacements for installed commercial systems that
The IDS must have a central control station where alarms annunciate, and from which a response force can be
dispatched. The response force should respond to an activated alarm as soon as possible, but in no case may
arrival at the scene take longer than 15 minutes. An alarm bell located only at the protected location is not
acceptable. Alarm circuitry that requires that alarm signals be cleared either by the central control station alarm
monitor or by entering the protected area must be used. The remote clearing of alarms before entering the area
and checking the alarm is not authorized. Some means of communication must be provided between the
protected areas and the monitoring area to coordinate status changes. Facilities located away from military
installations must have a local alarm in addition to monitoring capability. The use of alarm delay switches at
Reserve Component (RC) facilities is discouraged.
Where IDSs are used in civilian communities, arrangements must be made to connect the alarms to civil police
headquarters, to a private security company, or to a monitoring service from which immediate response can be
directed in case of unauthorized entry. The use of a commercial answering service is not authorized. This
coordination with civil authorities is required to ensure that a response force can be directed to the facility
Wherever possible, a daily log is maintained of all alarms received. This log includes the nature of the alarm (for
example, intrusion system failure or nuisance alarm), the date and time the alarm was received, the location, and
the action taken in response to the alarm. Such logs are maintained for a minimum of 90 days, and are reviewed
to identify and correct IDS reliability problems. A DA Form 4930-R (Alarm/Intrusion Detection Record) may be
used to record alarms received. An example of a completed DA Form 4930-R is shown in Figure 3-3. DA Form
4930-R may be reproduced on 8 1/2-by 11-inch paper. A reproducible copy of the DA Form 4930-R is located at
the back of AR 190-11. A computer-generated printout of alarms may be used to instead of this form if all of the
required information is included, or if supplemental information is included in a log.
The daily logs are reviewed periodically to monitor and correct IDS reliability problems. J-SIIDS problem areas
must be described in writing and sent through command channels to the Commander, US Army Belvoir Research
and Development Center, ATTN: AMCPM-PSE, Fort Belvoir, VA 22060-5606.
Transmission lines for the alarm circuits must be electrically supervised and dedicated to minimize undetected
tampering. For an example of this, see the data transmission system (type 1), described in TB 5-6350-264,
Selection and Application of Joint-Services Interior Intrusion Detection System (J-SIIDS), dated 28 July 1986.
Visible lines must be inspected periodically. A protected, independent backup power source of at least four hours
duration must be provided. The provision of telephone communication between a central control station and
alarmed zones (to provide for controlled entry by authorized personnel) should be considered as an adjunct to the
IDS. Telephone dialers and McCoullough Loop Communications applications may not be used.
