Optical Detector Clause Samples

Optical Detector a. The optical detector shall be a lightweight, weatherproof device capable of sensing and transforming pulsed optical energy into electrical signals usable by the phase selection equipment. b. The unit shall be high-impact polycarbonate construction with non-corrosive hardware. c. The unit shall be designed for simple mounting at or near an intersection on mast arm, pedestal, pipe, or traffic signal. d. The unit shall accept optical signals from all approaches to the intersection independently without modification or replacement of the existing phase selector unit. e. The unit shall include a design feature to allow aiming of the 2 optical sensing inputs for skewed approaches or slight curves, and may be field verified. f. The unit shall be responsive to the optical emitter at a distance of 1,800 feet. g. The unit shall be capable of providing the necessary electrical signal to the priority control unit (phase selector) through up to 1,000 feet of optical detector cable.
