CABINET INSPECTION <br /> Check the controllers, relays, and detectors to ascertain that they are functioning properly and <br /> make all necessary repairs and replacement. <br /> Keep interior of controller cabinet in a clean and neat condition at all times. <br /> 2. OBSERVE SIGNALS <br /> Observe the signals at the time of the bi-annual cabinet inspection. This involves stopping and <br /> watching for correct detection and timing operation. <br /> 3. DETECTION TESTING <br /> Test and inspect vehicle detection inductance loops, loop detectors, and pedestrian detection <br /> during cabinet visit bi-annually. <br /> 4. VIDEO DETECTION TESTING <br /> Inspect, maintain, and clean all video detection and surveillance systems every six months or as <br /> needed, to achieve clean lenses, proper alignment and proper focus. This shall include system <br /> camera, lenses, camera housings and hood/shield, pan, tilt, and zoom mechanisms and motors, <br /> mounting brackets and hardware, poles, microprocessors, controller, cables and communication <br /> equipment, and other related components. Maintenance shall include modifications to <br /> programmable detection zones. <br /> E. ANNUAL <br /> 1. RELAMP <br /> Clean reflectors, lenses and lamps once every twelve (12) months or as needed. Replacement <br /> of lamps shall be performed on the same occasion as the cleaning required in this provision. <br /> 2. CONTROLLER CHECK <br /> Remove and clean and overhaul the controller (except solid-state), relays, special auxiliary <br /> control equipment, and time clocks once a year or more often if necessary. When solid state <br /> controllers malfunction, they shall be removed, repaired, and bench checked. Solid state <br /> controllers shall not be removed for annual maintenance inspections. <br /> This annual check should verify software with central office software and reprint cabinet pack <br /> timings sheet. Controller check shall occur during a bi-annual cabinet inspection. <br /> 3. CONFLICT MONITOR TESTING <br /> Conduct a complete test of each conflict monitor and malfunction management unit. The <br /> following tests shall be performed: Indicator, System/Timing, ConflicWoltage/Clearance, <br /> Green/Green Permissive, Complete Permissive, and Extended (inc. Red/Green Dual Display, <br /> Watchdog Failure, etc.). It is recommended that testing be performed with the aid of an <br /> automated conflict monitor tester. <br /> 4.
