Nuisance Alarm. An alarm resulting from the detection of an appropriate alarm
stimulus, or failure to use established entry control procedures, but which does not
represent an attempt to intrude into the protected area. Examples of nuisance alarms
would be an improper opening of a monitored exit door or activation of an exterior
intrusion detection system by a DoD maintenance crew. Animal activation of detection
systems is a potential cause of nuisance alarms. Another example would be a wind-
generated alarm of a fence monitoring system caused by flexing of the fence (which can
be compensated for by a wind anemometer). Numerous nuisance alarms can cause
complacency.
Personal Identification Number (PIN). An identification string used as a password to
authenticate identity and gain access to a location or computer resource. Although
there are alphanumeric product options, most hardware entry devices make use of a
numeric keypad. Many computer resource programs require an alphanumeric string.
Physical Protection System, Physical Security System. Means of preventing
unauthorized physical access to a system, such as fences, walls, locks, sensors,
surveillance, and so on.
Premise Control Unit (PCU). A PCU is a specific term defined by DCID 6/9, used to
describe the CPU or local security panel for a SCIF. Per the DCID 6/9 definition: the
PCU receives signals from all associated sensors in the SCIF's alarmed zone and
establishes the alarm status. The alarm status is immediately transmitted to the
monitoring station. Within the monitoring station, a dedicated alarm-monitoring panel
(or central processor) monitors incoming PCU signals. On receiving an alarm signal, a
monitoring station's enunciator generates an audible or visual alarm for the monitoring
personnel.
performance in detecting an intruder within its detection zone.
Proprietary Security Network. A completely self contained dedicated local area
network (LAN) with security system software installed and run on a host server
(computer). Proprietary Security Networks are dedicated to the ESS with no outside
(Internet, LAN, or WAN) connections.
Regional Dispatch Center (RDC). A centralized security command center for multiple
bases and facilities within a geographic region. This location is typically staffed twenty-
four hours a day by staff trained to assess and initiate response for ESS alarms. The
RDC requires interface and communication systems to different bases and facilities.
The RDC concept is a trend of economically consolidating different base ESS at one
centralized location to save money and infrastructure of having different discrete base
operations center.
responsible for a standard (SEIWG-012) pertaining to information encoded on an
access control card. This standard is generally referred to as "SEIWG," although there
are other SEIWG specifications as well. Originally designed by the DoD, the standard's
