OPTIONAL FEATURES:
Self-Kill: Meets the ITE VTSCH-STD Part 2 Specification for "Failed State Impedance" Option
Night Dimming for Red & Green Signals: Meets ITE VTSCH-STD Part 2 Specification for Dimming Option
Communications:
RS 232/485 back to the controller
900Mhz radio to the ITIS S.A.P.S. unit (see ITIS Section for information on S.A.P.S.)
900 Mhz radio communications to a radio receiver installed in the intersection controller
These communication options allow for each signal with this option installed to communicate it's ongoing operational status to a central office database. This can be done through the USA Signal ITIS system S.A.P.S. unit or through the intersection controller if it has the I/O capability. When included in a USA Signal ITIS the software is provided as part of the system that lets the DOT management see action day to day status of all signals installed. With this system such key items as scheduling maintenance for signals that have degraded past the ITE light output specification can be done in a "real-time" mode.
