2 - FULL ACTUATED CONTROLLER 8 PHASE Article Description: Delete paragraph 1. Replace paragraph 2 with the following: This item shall consist of furnishing and installing an actuated controller, which shall be a completely digital solid state unit, for controlling the operation of the traffic signal, as indicated on the sequence and timing chart on the plans, and all necessary auxiliary equipment required. The control equipment shall be installed at the location shown on the plans or indicated by the Engineer, and in conformance with these specifications. All equipment must be compatible to operate with the ACTRA Closed Loop System. The traffic signal controller unit (CU), malfunction management unit (MMU), detector amplifiers, and all other ancillary traffic signal components included in the traffic control cabinet shall comply with the National Electrical Manufacturers association (NEMA) Standard No. TS , Traffic Controller Assemblies with National Transportation Communications for ITS Protocol (NTCIP) Requirements. Article Materials: replace the sentence with the following: Replace Article M Controllers with the following: The traffic controller supplied shall conform to Section 3 Controller Units of the NEMA TS 2 Standard. The traffic controller shall be supplied in a TS 2 Type 1 Configuration as required in the list of major traffic signal items included on the plans for each intersection location. Specifically, the controller unit (CU) shall be supplied as an actuated controller; defined as Type A1 in Subsection 3.2 of the NEMA TS 2 Standard. The controller shall utilize an interface conforming to Subsection 3.3 of the NEMA TS 2 Standard. The controller unit shall utilize an input/output interface conforming to the requirements of part of Paragraph for all input/output functions with the Malfunction Management Unit (MMU) and Paragraph for input/output functions with the Terminal Facilities (TF), loop detector amplifiers and auxiliary devices. The controller unit shall be a keyboard entry menu driven unit manufactured by Siemens/Eagle Signal, Model EPAC3608M60NEMA and conform to the Standard Specifications, with internal time base coordination, emergency preemption, and programmatic capability. The controller shall be complete with a module, including modem card and physical connector, to support closed loop communication. Controller shall contain a communications module with USB port. The local system intersection controller shall include all of the following internal functions: 1) Software compatible with the control and data protocol of an Eagle manufactured onstreet master, central office computer and field laptop computer 2) Local time based scheduler including automatic accommodation for daylight savings time 3) Local coordination control

3 4) Local preemption control with at least six programmable internal preemption sequences 5) Data uploading and downloading capability 6) Process system and local intersection detector activity and accumulate samples of vehicle counts, occupancy, speed, stops, and delay 7) Perform extensive failure evaluation of the controller, detectors, and communications; 8) provide local control of remotely selected NEMA and special functions 9) Perform local report generation with printer capability if a printer is attached, including intersection status and performance 10) All controllers of the same manufacturer shall always maintain backward and forward compatibility. A controller supplied today, or in the future must be able to run in a closed loop system supplied in the past without any upgrades or modifications required. Likewise, an older controller shall be capable of operating in a current closed loop system 11) Controllers shall be capable of Adaptive Max s. They shall operate as follows; after a phase maxes out twice in a row and on each successive max out thereafter, one step value will be added to the Adaptive Max until the value of the Dynamic Max is reached. Returning to Normal Max shall be achieved in the same fashion. After a phase gaps out twice in a row on each successive gap out thereafter one step value, and only one step value, will be subtracted from the Adaptive Max until the value of the Normal Max is reached. Each local system intersection controller shall include an internal FSK modem to allow connection to a remote system master. An RS 232C interface shall be provided to allow printing of local reports and database. It shall also be possible to attach a dial up modem to the RS 232C interface to allow remote control and monitoring of the local controller. A separate addressable RS232 port shall be supplied for use with radios or other external device. All controllers shall also have an Ethernet port and be IP addressable to function in an Ethernet system. To minimize training and simplify local programming, all local parameter access shall utilize prompting and English language displays, and all codes needed by the user, if any, shall be on the front panel or on the display screen to avoid the need for memorization or the presence of a manual. TRAFFIC CONTROLLER CABINET The controller cabinets shall conform to the NEMA TS 2 Type 1 Standards, Section 7. Cabinet size shall be as indicated on the plans and as shown below.
