Rainbow Control eventually served 17 communities.  The Rainbow Control system designed by "Doc" O'Brien was considered the "grandfather of all emergency dispatching systems" across the country.

This system dispatched fire, police and ambulance and was also used as a model for the 911 system throughout the country.  Rainbow Control was in existence until December 31, 1989 at which time Westmoreland and Armstrong counties took over dispatching duties for the valley.

Some departments still use these colors to this day!
