INTENT
These specifications describe the requirements of the City of Aurora Colorado for traffic signal heads designed to direct the movement of pedestrian traffic.
STANDARDS
Equipment furnished under these specifications shall conform to the standards of NEMA, ITE, IEEE, and UL as applicable.
GENERAL
Pedestrian signals shall consist of a single piece cast aluminum housing, a single piece cast aluminum door frame, a “egg crate” sun visor, a LED signal module, and other appropriate hardware. The subject pedestrian signal shall be capable of displaying, brightly and uniformly, the alternate symbol messages, "HAND" in Portland orange and "WALKING PERSON" in lunar white. The messages shall be full figure (not outline).
CASE
The case shall be one piece corrosion resistant aluminum alloy casting compete with integrally cast top, bottom, sides and back. The case when properly mated to other pedestrian signal components and mounting hardware shall provide a weatherproof enclosure and shall provide for easy access to and replacement of all components. The case shall contain upper and lower openings suitable for bracket mounting. The openings shall accommodate standard 1-1/2" pipe brackets at the top and bottom of the case. Positive positioning to eliminate rotation or misalignment of the signal shall be accomplished by the use of a serrated 72-tooth mounting ring integrally cast into the mounting hole in the case.
DOOR FRAME
The door frame shall be a one piece corrosion resistant aluminum alloy die casting, complete with two hinge lugs cast at the bottom and two latch slots cast at the top of each door. The door shall be attached to the case by means of two stainless steel pins. Stainless steel hinged bolts with captive stainless steel wingnuts and washers shall be attached to the case with the use of stainless steel pins. Hence, latching or unlatching of the door shall require no tools.
VISOR
Each signal shall be provided with a visor designed to eliminate sun phantom. The “egg crate” type visor assembly shall be held in place by the use of stainless steel screws or lens clips. The visor must be removable for cleaning and maintenance purposes.
PAINTING
Prior to final assembly the aluminum pieces shall be thoroughly cleaned, etched and powder coated to provide a low luster flat black finish on the door and visor and a Federal Yellow finish on the housing.
LED MESSAGE MODULE
Each pedestrian signal assembly shall be equipped with a LED signal module. The LED modules shall be weather tight, fit securely in the housing and shall be wired to respective terminals of a three pair screw-type terminal block located inside the pedestrian signal housing. The message-bearing surface of the module shall display fully populated “HAND” and “MAN” side by side symbols. When provided with a countdown timer, the symbols shall be fully populated “HAND” and “MAN” overlapped symbols. Illumination shall be provided by an array of LED lamps behind a rigid lens.
The LED pedestrian signal module shall be a single, self-contained device requiring no additional assembly for installation into existing housings. The lens of the LED pedestrian signal module shall be fabricated from UV stabilized polycarbonate plastic and shall be a minimum of 3/16 ” thick. The “Hand” symbol shall be Portland Orange. The “Man” symbol shall be Lunar White. All Portland Orange LEDs shall be “AlInGaP” technology or equal, and rated for 100,000 hours or more at 25ºC and 20 mA. “ALGaAS ” technology is not acceptable. White LEDs must be InGaN technology. Each individual LED traffic module shall be identified for warranty purposes with the manufacturer’s trade name, serial number and operating characteristics, i.e. rated voltage and power consumption.
ENVIRONMENTAL REQUIREMENTS
LED pedestrian signal modules shall be rated for use in the ambient operating temperature range of -40ºC to +60ºC. LED pedestrian signal modules shall be protected against dust and moisture intrusion per requirements of NEMA Standard 250-1991, sections 4.7.2.1 and 4.7.3.2, for type 4 enclosures.
ELECTRICAL
LED pedestrian modules shall be operationally compatible with current NEMA (TS-1, TS-2) controller assemblies and conflict monitors. LED pedestrian signal modules shall operate from a 60 ±3 Hz AC line over a voltage range of 80 to 135 VAC. The LED circuitry shall prevent perceptible flicker over the voltage range specified above. The LED pedestrian signal module circuitry shall include voltage surge protection against both high and low-repetition noise transients as stated in Section 2.1.6, NEMA Standard TS-2, 1992. Failure of one LED light source shall not result in the loss of more than three LEDs or 5% of the signal light output. LED pedestrian modules must meet Federal Communications Commission (FCC) Title 47, Subpart B, Section 15 regulations concerning electrical noise emission. The LED pedestrian module shall provide a power factor of .90 or greater over the operating voltage and temperature range specified above. Total harmonic distortion (current and voltage) induced into an AC power line by an LED pedestrian module shall not exceed 20% over the specified operating voltage and temperature range.
Message configuration shall be the "HAND" symbol on the left half of the message surface and a "WALKING PERSON" symbol on the right half. The "HAND" and "WALKING PERSON" symbols shall each be a minimum of 11" in height and 7" in width. Message configuration, color and size shall be Class 3 as defined by the I.T.E. Equipment Standard "Pedestrian Traffic Signal Control Signal Indications" dated March 1985.
COUNTDOWN TIMER
LED pedestrian modules equipped with countdown timers shall meet the following requirements:
The countdown module shall be operationally compatible with current NEMA (TS-1, TS-2) controller assemblies and conflict monitors. The countdown timer control module shall be of the “smart” type having a processor capable of setting it’s own time when connected to the pedestrian signal field wires. The timer module shall continuously monitor the pedestrian signal operation for any changes in the timing and shall re-program itself in response to any changes. The module shall blank out the display during the initial cycle while it learns the pedestrian signal timing. The module shall operate in the “Clearance Cycle” or “Coordinated” mode, with the countdown timing only the flashing “Don’t Walk” interval. In the case of recycling pedestrian phases, the countdown signal shall operate normally. When the pedestrian phase is recycled, the countdown signal shall display the correct time and terminate the count even if the solid hand indication is replaced by a walking person indication.
WARRANTY
The pedestrian signal shall be warranted for a minimum of two (2) years from the date of original shipment against defects in workmanship and/or materials. The LED module shall be repaired or replaced by its’ manufacturer if it exhibits a failure due to workmanship or material defect within the first 60 months of delivery.
