Step 1: With the center of the luminaire assembly positioned between the center two nozzles at a distance of 18 inches, adjust the apparatus so that the spray is directly aimed at the luminaires’ photometric nadir (Position #1) of the luminaire.

Step 2: Energize the luminaire for a minimum of 30 minutes, and then turn on the water. After 15 minutes of water application, de-energize the fixture, leaving the water spray on for 15 more minutes.

Step 3: Within 30 minutes of turning off the water spray, rotate the assembly to directly apply spray at electrical entry or access, (Position #2) and repeat Step 2.

Step 4: Immediately after turning off the water spray, dry the exterior surfaces of the assembly(s) using a dry cloth, then open the entry points to investigate whether the luminaire shows any evidence of water entry under the conditions specified (maximum time between turning off the water and opening the assembly(s) to be 15 minutes). Water leakage (water entry) signifies failure for the position and test. Additionally, if any latch releases during the procedure, shall be cause for failure for that position and test.

E. Vibration Test. While attached to its mounting plate in the orientation for which it will be installed, the complete luminaire (same luminaire), with LED lamps and drivers installed, and shall successfully pass a vibration test at 2 g loading for 100,000 cycles in two of the three major axes and a 4 g test for 5000 cycles in one axis chosen by the Quality Assurance Manager.

Each lighting contactor shall be rated for 480V, 3 phase, 3 pole, 30 amp. The contactors shall be electrically held with a 120VAC coil. Provide each lighting contactor with auxiliary contact for status indication and input to the tunnel lighting controller.

G. Control Panel

1. Enclosure

The controller shall be housed in a surface mounted NEMA 12 enclosure of sufficient size to include all input power distribution, operator interface, low voltage control and lighting contactors. All components shall be pre-wired, factory tested and configured in the control panel enclosure

2. Operators and Indicators:

In addition to the operator interface terminal’s keyboard the front panel shall include HAND/OFF/AUTO selector switches and status lights for each controller channel.

Manual Operator control shall be accomplished through a front panel Hand/Off/Auto Selector switch for each channel. The Hand position switches the lighting contactor on, closing its power poles. The Off position switches the lighting contactor off, opening its power poles. The Auto position allows the controller to operate the contactor as the program’s setpoints and timers require. Operator legend and indication nameplates shall be provided.

Each HAND/OFF/AUTO switch’s AUTO position shall be monitored by the tunnel lighting controller.

3. Controller Outputs:

Each output circuit shall have a 2 Amp inductive load rating, capable of operating low voltage electrically held contactors. Single pole 15A interposing relays shall energize high voltage lighting contactor coils. Indication shall display individual circuit status, power on, and sensor condition.

4. Control Panel Power Distribution:

Input power shall be 120VAC and terminate inside control panel. Low voltage control power shall be 24VDC. Control power supply shall be appropriately fused. Circuit breakers shall be used to protect devices over 10A. All high and low voltage components shall be separated by a barrier. Power distribution wiring shall be not less than 14ga.

H. Certification/Start-up

1. The photo lighting control system shall be factory tested to ensure proper operation of all switching controls, analog and digital transmissions, and operator interface.

2. The photo lighting control system shall be ETL certified to comply with the standards of UL/ANSI 508A for industrial control equipment.

EISENHOWER LOCK TUNNEL LIGHTING UPGRADE Page 265540- 14

3. A factory authorized technician shall perform system startup including: sensor calibration, loop checkout, and commissioning.

4. A 2hour training session shall be provided. The training shall include:

a. Sequence of operation

b. Component identification

c. Operator interface terminal menus

d. Communication

e. Maintenance

5. An edited and annotated DVD of the training session shall be provided to the Owner.

PART 3 EXECUTION

3.1 PERFORMANCE REQUIREMENTS

A. Perform all Work in accordance with the requirements of NFPA 70 and 502, and those authorities having jurisdiction. Verify that other construction work is complete to the extent that Luminaires may be installed. Install Luminaires of the type required in the locations shown and make all final electrical connections. Provide accessories as required to properly install the material defined in this section even though these accessories may not be specifically indicated on the Plans. Provide appropriate support(s) for each lighting fixture. Fixtures and support elements shall not be mounted on or in contact with ducts or pipes.

3.2 INSTALLATION

A. Install rows of fixtures accurately on straight lines unless otherwise indicated on the Plans.

Install all necessary hangers, channels, bars, supports, and rods required to align Luminaires.

B. Fixture Adjustment: Provide labor and materials for final adjustment of all fixtures to the Quality Assurance Manager’s satisfaction. Adjustment shall take place immediately before the work is accepted by the Quality Assurance Manager.

C. Meter Alignment: Provide labor and materials for final aiming of all meters to the Quality Assurance Manager’s satisfaction. Aiming shall take place immediately before the work is accepted by the Quality Assurance Manager.
