The photo electric controls, hereinafter referred to as PEC, shall comply with the electrical requirements specified in the standard drawings. The nominal dimensions shall be as shown on the standard drawings. The operating temperature range shall be from - 40 to +158 degrees F with zero to 100 percent relati ve humidity. A time delay shall be incorporated into the circuit to prevent the lights from being turned off at night by transient lights which might be focused on the control. The PEC shall be a conventional glass faced, hermetically sealed cell. A swit ch to permit manual operation of the lighting circuit shall be provided for each PEC. The PEC shall work in conjunction with an external auxiliary load relay for handling the required lighting loads unless specified otherwise. The PEC shall have a built -in lightning arrester and inrush current protection. The encapsulated surge protector shall have a spark- over value of 2 kilovolts and shall interrupt up to 10 kiloamperes of follow - through current without affecting the operating characteristics. Voltage R ating : 120 to 277 volts AC, 60 hertz Load Rating: 8 A LED Turn on: 1.5, ±0.5 foot candles. Turn off: 2.25 foot candles Time delay: 2 to 5 Seconds Fail Mode: ON Power Consumption: Less than 0.65 W Water ingress protection: NEMA 3, raintight Life rated at full load: No less than 10,000 On- Off operations. Regulatory Listings shall include: ANSI C131.10 and RoHS compliant ; UL 773 certified; and Tested to NEMA 410 LED Load Standards.
Unless otherwise specified, an auxiliary contactor shall be used in conjunction with a PEC to control the required lighting loads. The contactor shall have contacts rated to switch the specified lighting loads and shall be normally open. The contactor shall be single -pole or double- pole as required. The contactor shall be installed as shown on the plans. TABLE OF CONTENTS INDEX 946
A manual -off-photo switch shall be installed, as shown on the Standard Drawing to manually activate the contactor to turn the lights on or off. The switch shall be the toggle- type having double- pole, double- throw contacts with the center position being the "off" position, and be rated at 10 amperes at 250 volts A.C. The switch shall be manually activated in the up position and shall be activated by the PEC in the down position. 736- 2.07 Load Center Cabinets: Load Center cabinets, including pole mounted cabinets shall have photoelectric controls and shall also include a concrete foundation, conduit stub- outs, meter socket, rigid metal conduit riser, cabinet housing, panel, br eakers, contactor, selection switch, fuses, dry transformer, internal wiring and other incidentals in accordance with the project plans and these specifications. The load center cabinet housing shall be of NEMA 3 R weather resistant construction and UL 508 listed. The cabinet and doors shall be made from ⅛ inch thick, 5052 -H32 aluminum with mill finish. All exterior cabinets shall have continuous welding and be free of burrs. The cabinet top shall be sloped to prevent water accumulation; and shall be constructed to allow proper ventilation and be equipped with a washable or replaceable air filter. Doors shall be attached using continuous hinges, equipped Corbin locks, and keyed #2 with two keys. Doors shall also be equipped with two position door stops, three- point door latch with rollers for top and bottom strikes and pad -lockable handles. Circuit breakers shall be molded case, thermal magnetic, bolt -on or plug - in type and shall be U.L. listed. Load center cabinets shall have a dead front panel to isolate all live electrical circuitry. The panel shall be fabricated from aluminum sheeting and shall be painted the same as the cabinet. The dead front panels shall be hinged on one side and securely fastened on the other with bolts. Switches, breakers and other components shall have openings to operate from the front panel. 736- 3 Construction Requirements: Each LED light shall be installed as a complete unit. The contractor shall maintain full nighttime operation of the existing lighting system during the duration of the construction project , unless otherwise approved by the Engineer . 736- 4 Method of Measurement: Luminaires will be measured as a unit for each luminaire furnished, installed, and operational .
