The 138 blue light voice communication units covering the UVM campus create an environment students can feel safe in. Each unit is illuminated by a blue light for easy location and contains two communication buttons. The black button connects the user with a UVM Information Operator. When the red button is pressed, UVM Police Services is contacted through a recorded, official 911 line. When red buttons on multiple lights are pressed in succession, Police Services can track which have been pressed and follow the path this creates. Pressing the red button also causes the blue light to go into a flashing strobe mode.
