Sigtronics US-12D - Manual

INTRODUCTION
ATTENTION INSTALLER: To assure a trouble free installa-
tion, please read these entire instructions through once
before beginning.
The Sigtronics UltraSound Emergency Intercom System,
when used with Sigtronics noise attenuating headsets pro-
vides 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” communication 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
UltraSound unit models US-12S and US-12D. More headset
positions can be achieved by wiring additional jacks in par-
allel. Only one headset, however, can be plugged into paral-
leled 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 head- set into his jack while driving.
He then unplugs and plugs into the pump panel when he
arrives on scene.
