2.4.15.4
Card Reader and Keypad Access Control Devices
**************************************************************************
NOTE: Specify only one type of access control card.
Be sure card type and card readers are compatible
with each other.
**************************************************************************
Devices shall be tamper alarmed, tamper and vandal resistant, and solid
state, containing no electronics which could compromise the access control
subsystem should the subsystem be attacked. Devices shall be surface,
semiflush, pedestal, or weatherproof mountable as specified for each
individual location. [Each device shall contain a visual display, mounted
on the face, to indicate access or exit request processing, request
approval, and request denial.] Card readers shall be the [proximity]
[insertion] [swipe-through] type and shall be capable of reading [magnetic
stripe] [high coercivity magnetic stripe] [Wiegand] [Hollerith] [proximity]
[_____] type access control cards. Keypads shall contain an integral
12-digit tactile keyboard with digits [arranged in numerical order]
[scrambled for each access or exit request]. Keypad shall be [a
stand-alone device] [or] [integrated into the card reader].
2.4.15.5
Access Control Cards
**************************************************************************
NOTE: Determine the format, logo, and wording for
the cards from the using activity before final
design. A unique facility code may only be
available with the purchase of 5000 cards or more.
**************************************************************************
Cards shall be manufactured with capability of modification and lamination
during enrollment process without reduction of readability for use as a
picture and identification badge. Cards shall contain binary coded data
arranged in a scrambled pattern as a unique identification code stored on
or within the card and of the type readable by the subsystem card readers.
Include within the card binary data a nonduplicated unique facility access
control subsystem identification code common to access control cards
provided. [Cards shall be designed for use as a photo identification card
suitable for lamination.]
2.4.16
Communications
Communications shall link together subsystems of the IDS. IDS
communications links shall be via hardwire (cable) [or radio frequency].
Communications links shall be supervised. Common communications interface
devices shall be provided throughout the IDS. Sensor to control unit
interface shall be by dry relay contact normally open or normally closed,
except as specified otherwise. Control unit to central alarm reporting and
display processor interface shall be digital, asynchronous, or multiplexed
data. Individual data bits shall be grouped into word format and
transmitted as coded messages. Interface shall be implemented by modems
which function as a communications controller, perform data acquisition and
distribution, buffering message handling, error checking, and signal
regeneration as required to maintain communications.
