INTRODUCTION
ATTENTION INSTALLER: To assure a trouble free installation,
please read these entire instructions through once before
beginning.
The Sigtronics UltraSound Emergency Intercom System, when used
with Sigtronics noise attenuating headsets provides the emergency
apparatus crew with clear, hands free, voice activated (VOX) intercom.
The system also allows full radio monitoring at all headset positions
as well as radio transmit capability from selected headsets via Push-
To-Talk (PTT) switches.
Applications: The unit is designed for fire apparatus, rescue and
ambulance vehicles, marine emergency equipment, airport ground
vehicles, and mobile emergency command centers.
Voice Activated Intercom (VOX) feature allows “hands free” com-
munication between headsets connected to the UltraSound unit.
Start speaking and the intercom turns on instantly to relay your
message clearly to the other headsets. Stop talking and it turns off
to reduce background noise.
Up to Twelve Headset Positions can be connected to the Ultra-
Sound unit models US-12S and US-12D. More headset positions can
be achieved by wiring additional jacks in parallel. Only one headset,
however, can be plugged into paralleled jacks at one time. This
paralleled jack scheme is most commonly used on pumper trucks
at the pump panel. In this case, the Driver plugs his headset into his
jack while driving. He then unplugs and plugs into the pump panel
when he arrives on scene.
