remotely. A list of local and remote controls, indications, and alarms shall be for

Metro approval for each specific TPSS design in order to provide its safe and

reliable operation. The interface with the remote operation at ROC shall be

coordinated d with the respective SCADA system connected to the Rail

Operations Control-ROC.

H. Auxiliary Equipment

1. Lighting

Indoor lighting shall be provided by fluorescent fixtures. Design shall provide

for minimum maintained lighting levels of 30 foot-candles vertical, average.

Such lighting shall be located so as to illuminate satisfactorily the vertical

surfaces of equipment such as switchgear and transformer rectifier units.

Locations of lighting fixtures shall be coordinated to avoid interference with

overhead raceways or other major wiring and shall not be directly above

switchgear, rectifiers, or transformers. Outdoor lighting shall be provided by

energy efficient lamp fixtures with built-in photocell control. Design shall

provide a minimum illumination level of one foot-candle at ground level. The

general lighting shall be controlled from switches located near each access

door.

2. Emergency Lighting

Substations shall be provided with emergency lighting from individual self-

contained, maintenance-free units, with one or more lamps mounted on the

equipment and a relaying device arranged to energize the lamps

automatically on failure of AC power. Batteries shall have 1-1/2 hour

minimum cut-off capacity from fully charged state and shall have testing

means accessible from outside. Sufficient fixtures shall be provided to

illuminate egress paths as required by code(s).

3. Convenience Outlets

Duplex convenience 20 amp outlets shall be located approximately 25 feet

apart around the interior walls of the substations And within 10 feet of AC

and DC protection relays (for testing equipment purposes).

4. Auxiliary Equipment

Other auxiliary equipment shall include, but not be restricted to, Batteries

and UPSs for DC and AC control power and essential loads, AC and DC

distribution panels, Local Panel Annunciators- LAPs, Smoke Detectors and

Fire Control Panel-FCP, intrusion detection system, and provision for stray

current corrosion measurements and/ negative return drain connections

I. Construction and Equipment Arrangement

1. Underground Substation rooms or outdoor housing shall have adequate

area to permit placement of electrical equipment and ancillary components

of any manufacturer. Relative spacing and positioning of each equipment

unit shall permit the removal, replacement, or maintenance of such unit

without the necessity of moving other units. The arrangement of the
