batteries. A small, flexible PVC-encased antenna shall be mounted
10 mm 1/2 inch away from the transmitter to ensure reliable
propagation of the alarm signal and rotation of 6.28 rad 360
degrees without damage to the sensor. Provide a case to prevent
corrosion in hostile environments. Transmitter shall be available
in both the very high frequency (VHF) and ultrahigh frequency
(UHF) radio bands. The transmitter shall be FM modulated to
ensure reception and decoding of the alarm signal. Signal
transmitted shall readily interface with the IDS communications
subsystem as specified in paragraph entitled "Radio Frequency
Link." Activation of the sensor shall be by hand-operated switch
protected from accidental activation, yet easily activated by hand
when worn at the waist on a belt. [Sensor activation shall be
automatic when mounted on a belt and the wearer is in a horizontal
position for longer than [one] [5] [15] [_____] minutes,
adjustable. Adjustment of time interval activation shall not be
accessible to operations personnel.]
2.4.15
Basic Automated Access Control
Provide basic automated access control subsystem based upon a modular
distributed microprocessor architecture complete with access control cards
and ready for operation. [Subsystem shall interface with and provide alarm
and other status to the overall IDS.] [Subsystem shall provide monitoring
and control for the IDS.] Subsystem shall meet the Grade [AA] [_____]
communications requirements of UL 1076 and UL 294 and shall have the
capability of controlling up to [32] [_____] card reader and keypad access
control devices. Subsystem shall grant or deny access or exit based upon
keypad identification data, card identification data, or a combination of
both, input through the card reader and keypad access control devices
compared to data stored within the system, as well as time of day and day
of week. Decision to grant or deny access or exit shall be based upon
authorization for such data to be input at a specific location for the
current time period. [Access decisions for high security areas shall be
based upon combination of card and keypad data.] When conditions are met,
a signal shall be sent to the input device location to activate the
appropriate electronic strike or release. Under normal operations,
subsystem shall provide both a hard copy and a magnetic data record of
valid transactions upon occurrence. Record shall include identification of
the individual, location, and time of day. When access is denied, an alarm
shall be initiated and subsystem shall provide a record of time, location,
and reason for denial. Subsystem shall incorporate a provision for
entering a special code to indicate duress from keypad data entry devices.
Code shall cause duress alarm initiation while granting access, when other
authorization criteria are met. Subsystem shall provide an interface to
the IDS to enable identification of alarm type, location, and annunciation
of access control subsystem alarms by the IDS. Subsystem communications
shall be by dual independent multiplexed data communications channels.
Subsystem power requirements shall be as specified in paragraph entitled
"Electrical Power." Access control data bases shall be protected by UPS
and backup batteries as specified in paragraph entitled "Backup Power."
2.4.15.1
Error and Throughput Rates
Rates shall be portal to portal performance averages obtained when
processing individuals one at a time. When serial verification techniques
or multiple attempts are required to satisfy error performance
requirements, features shall not reduce capability to meet throughput
requirements. A Type I error denies access to an authorized enrolled
