Description The Multisonics 820 controller combines advanced technology with the practical requirements of modern traffic engineering, maintenance and safety. Easy to operate, flexible enough to work in any situation, the 820 is the best choice for many traffic controller applications. The 820 meets or exceeds all current controller standards as described in NEMA Publication No. TS-1 1983. The Multisonics 820 is a two-to-eight phase (with pedestrian service on all phases), four overlap, dual-ring controller. It is designed for immediate operation under the control of a Multisonics VMS - 330 vehicle Management system computer. The 820 can also serve as a stand-alone controller operating in actuated or non-actuated mode, or as part of a hardwired street master system. Standard features (which exceed NEMA requirements) include railroad preemption, emergency vehicle preemption (four channels), internal time based coordinator, programmable dimming and a real-time quartz controlled clock/calendar. The three-part keyboard of the Multisonics 820 is used to set, edit and/or observe all controller timing and features. The user is guided through the simple process by English language menus which prompt for the required responses. All menus and prompts are displayed on a front panel thirty-two character alphanumeric LCD readout. The panel also features a 3” x 3” graphics LCD which displays intersection geometry and status. The latest in electronic technology has been used throughout the 820 to reduce the number of circuit boards to only four: MPU, I/O with NEMA connections, display/keyboard and power supply. All circuitry is enclosed in a heavy-duty black baked–enamel steel structure. For a cost-effective way to meet traffic controller needs while making use of many exclusive standard features, the 820 Traffic Controller from Multisonics is the ideal solution.
