1.2.10.2
Movement
Standard intruder movement is defined as any movement such as walking,
running, crawling, rolling, or jumping through a protected zone in the most
advantageous manner for the intruder.
1.2.11
False Alarm Rate
1.2.11.1
Interior
A false alarm rate of no more than 1 false alarm per sensor per 30 days at
the specified probability of detection shall be provided.
1.2.11.2
Exterior
A false alarm rate of no more than 1 false alarm per sensor per 5 days at
the specified probability of detection shall be provided.
1.2.12
Environmental Nuisnce Alarm Tate
Environmental alarms during nominal conditions shall not exceed 1 per day
per sensor.
1.2.13
Error and Throughput Rates
Error and throughput rates shall be single portal performance rates
obtained when processing individuals one at a time.
1.2.13.1
Type I Error Rate
Type I error rate is defined as an error where the system denies entry to
an authorized, enrolled identifier or individual. The rate shall be less
than 1 percent.
1.2.13.2
Type II Error Rate
**************************************************************************
NOTE: The designer will decide what level of
security is appropriate for the project. An error
rate of 0.1 percent should be used for medium
security projects, and 0.01 percent should be
selected for extremely high security projects. The
smaller number will be more difficult to meet and
therefore more costly. The designer should
carefully consider the needs of the site when making
this choice.
**************************************************************************
Type II error rate is defined as an error where the system grants entry to
an unauthorized identifier or individual. The entry control Type II error
rate shall be less than [0.1] [0.01] [0.001] percent.
1.2.14
System Throughput
**************************************************************************
NOTE: To support this paragraph the designer will
show the throughput rates needed at each portal on
the drawings or in a table. The designer will
calculate the number of people required to pass
