SQ2MPR Features
- Hand-held remote control allows workers to take manual control of traffic when necessary.
- Work Light provides visual cue of automatic or manual mode status.
- “Patterned” work light flash provides visual cue of red or green system display whilein manual mode.
- Horn provides audible cue that modes have changed (or system failure has occurred).
- Signal Safe Radio provides system switch to automatic, quartz-controlled mode if radio signals are interrupted — all communications errors are monitored and recorded.
- Time/Traffic Programming — user-friendly, intuitive operation supports either time block or traffic information to create the traffic control program.
The set times, operating instructions and fault/error messages are indicated in the display window. In addition, program monitoring is possible in real time while the program is running simply by viewing the display. For example, the operator can see which light has the green signal and the amount of time that remains. Fail-safe programming integrity prevents inadvertent reductions of “clear time” settings by the operator in the work zone.
