The DVP-120 can drive the buzzer, horn and strobe with different sound patterns to indicate the severity of the 
current conditions. These patterns are selectable by the installer using this group of submenus. Once again, the 
left and right keys will scroll through the signal types and the up and down keys will scroll to the signal sources.
