METRO RAIL DESIGN CRITERIA SECTION 9 / SYSTEMS

DE304.09 9-128 Revision 4 : 05/09/12

Metro Baseline Re-Baseline: 04/29/10

installations shall be inconspicuous and not easily identifiable to the general

public.

a. The key card shall contain a machine-detectable code indicating unique

security classification number (SCN). When an employee uses a key

card to activate a card reader adjacent to a controlled door, the

subsystem shall release the electric lock if access is authorized for the

specific card, based upon door number, time of day, and day of the

week.

b. The subsystem shall maintain a record on magnetic disk. The record

shall include intrusion alarms, diagnostic alarms, all card reader events

and authorization status. The date, time, location, card identification,

card holder's name, department badge number and SCN shall be

recorded with each record. These records shall be retrievable via both

CRT screen and hard copy. Functions for archiving and restoring

records shall be provided,

c. The IDS server at ROC shall be a pair or computers operating in

primary/standby configuration with automatic failover. All system

configuration and alarm/event data shall reside on RAID protected

shared disk memory.

d. If the subsystem fails or is out of service due to a communications loss

with the IDS server, its functions shall transfer to a backup mode of

operation. While the backup mode is in effect, access to a door shall be

granted when a zone code ascribed to the security classification number

on a card coincides with the zone code assigned to the door where the

card is presented.

e. If both the subsystem and its backup mode fail, door releases shall be

effected from a remote terminal. In the event of a total failure, a

mechanical means of activating door releases for exiting through the

controlled doors shall be provided. This provision shall allow the

preselection of the appropriate failure mode, be it locked or unlocked, for

each specific door.

f. The controlled access or intrusion detection system shall not inhibit

egress.

g. The subsystem shall provide the capability of authorizing and voiding a

single SCN or a group of SCNs. The subsystem shall provide the

capability of assigning employee names, department, badge numbers

and zone codes to each SCN. The subsystem shall provide the

capability of authorizing combinations of door numbers, SCNs, times of

day, and days of the week. The subsystem shall prevent alterations of

the data by unauthorized persons and provide capability for changing

access codes and validations on a real-time basis.

h. The subsystem shall provide selection capability to print out authorized

access and/or print out only rejected access attempts.
