such as batteries, fire alarms.
6. Miscellaneous relays, terminal blocks, and associated
wiring.
7. Input/output modules (IOMs) associated with the TPF backup
control system to provide a secondary independent fiber optic
interface between C02 mimic panel local controls and the TPF
breakers. The TPF backup control system serves as redundant means
of breakers’ monitoring and control in case the associated of the
failure of the TPF’s control Ethernet switch(es), RTAC PLC, the
associated modules and/or the associated communications path
components. Input output modules shall be installed in the C02
panel and the matching pair shall be installed within the AC and DC
switchgear lineups.
8. Interior light fixture with door-activated switch providing
600 lumens minimum and an AFCI 120V AC duplex receptacle.
9. Lamp test button. This may be incorporated in the HMI.
B. The C02 panel shall be fully functional with spare capacity
to accommodate all monitor, control, and display devices and
equipment of the TPF, existing equipment and devices, and any
future additional equipment as indicated. Depending on the type of
the TPF, C02 panel shall provide for monitoring and control of all
facility equipment as indicated.
C. C02 and C04 cabinets shall be implemented as two separate
standalone cabinets. Depending on substation space restrictions,
the District may consider having the C02 panel inhouse the C04
panel and the C04 equipment integrated into C02 panel enclosure
(see detailed requirements for the C04 panel below).
D. The C02 panel, C04 panel, CCA cabinet and related equipment
are based on the use of an industrial grade, off-the-shelf RTAC
type PLC, network switches and operator display capable of
efficient operation in a harsh electrical, high temperature,
vibrating, and physically dirty environment. Obtain District
approval in writing of equipment and components.
E. Ethernet physical ports shall be implemented as interfaces
over fiber-optic media, 100Mb/s multimode or greater. Some
interfaces may use copper Ethernet interface, as shown on the
Contract Drawings. There shall be two independent C04 panel
Ethernet switches (switch stacks) supporting two independent
non-bridgeable VLANs. Equipment shall include the following:
1. One network for use by the C02 PLC data acquisition and
control network (Control VLAN).

ISSUED: DECEMBER 2020 PAGE 8 OF 35 STANDARD SPECIFICATIONS
2. A second network for access to each TPF network device such
as MPR, IPR, NGD, IOM, transformer controller, rectifier
controller, ETTS logic controller and, if applicable, 125 VDC TPF
battery backup system controller maintenance data (Maintenance and
Engineering VLAN).
Interfaces between the C02 PLC and other devices in the TPSS
shall be as indicated and as specified herein. For devices, that
support only a single (not dual) IP-addressable physical port, when
approved by the District, it is acceptable to implement the
Maintenance and Engineering VLAN interface utilizing the devices’
spare serial (or USB-serial) ports and terminal server equipment
connected to the Maintenance VLAN switch. For such cases, to enable
galvanic isolation, this interface shall be done over the fiber
optic media that may use, where necessary, fiber optic media
converter and terminal server equipment between the origin and the
destination of the interface.
F. TPF CCTV cameras and access control panel Ethernet interfaces
shall be connected to the Security Ethernet switch in the CCA
cabinet. TPF VOIP emergency and IP telephone Ethernet interfaces
shall be connected to the VOIP Ethernet switch in the CCA cabinet.
The CCA security Ethernet switch shall be configured to be a part
of the Security VLAN. The CCA VOIP Ethernet switch shall be
configured to be a part of the VOIP VLAN. Both Security and VOIP
VLANs shall be independent from the Control VLAN and the
Maintenance and Engineering VLAN. The CCTV data shall be passed to
a BART centralized location for processing camera video and storage
via BARTNet (see Contract Specifications Section 28 41 29, CCTV for
the detailed requirements of the TPSS CCTV System).
Correspondingly, the TPF access control panel indications and
controls shall interface BART centralized security office via
BARTNet too (see Contract Specifications Section 28 10 01, Access
Control for the detailed requirements of the TPF Access Control
System). The TPF emergency and VOIP telephones shall provide for
telephone signaling with the BART phone system (see Contract
Specifications Section 27 30 01, Telephone Systems for the detailed
requirements of the TPF Telephone System). The CCA Ethernet
switches shall provide for PoE+ compliant power for TPF CCTV
cameras and VOIP Emergency and IP telephones. See detailed
requirements for the CCA cabinet herein.
G. TPF Ethernet switches shall facilitate interfaces to the
corresponding equipment in BART headend offices via single-mode
fiber optic uplinks between the TPF site and the existing BARTNet
Ethernet switches located inside the train control room closest to
the TPF.

to normalize the data prior to sending it to ICS, EBP, or NYMS.
C. Configure the C02 PLC as follows:
1. Perform necessary monitoring and control requirements for
traction power and ancillary equipment in each TPF, including the
data transfer requirements between the C02 PLC, the C02 operator
panel, the C02 mimic panel, the ETTS, and the SCADA PLC.
2. As applicable for each TPF, the 34.5 kV AC circuit breaker,
transformers, rectifiers, PIOMs, NGD, DC buses, DC switchgear and
third rail interconnects schematic reference diagrams present the
C02 panel’s monitoring and control requirements in a hardwired

requirements as shown on the Contract Drawings and as specified
herein.
3. The minimum monitoring and control requirements for traction
power equipment are shown on the Contract Drawings. The monitoring
requirements for all specified ancillary equipment such as AC and

be logic “true” for each i/o point reported to these systems and
“0” representing logic “false” for the i/o point. This shall remain
the case for points that need to be wired in a “fail-safe”
(normally-closed) manner, requiring an additional step to normalize
the data prior to sending it to ICS, EBP, and, if applicable,
NYMS.
